A study was conducted with 36 tomato germplasm [PGRC (19), The Netherlands (7), Japan (2), and Bangladesh (9)] with 3 check varieties in the research field of the Olericulture Division of Horticulture Research Centre (HRC), Bangladesh Agricultural Research Institute (BARI), Gazipur during the winter season of 2022-23 to identify promising tomato breeding germplasm. All the germplasm showed differences in most of the parameters studied. Considerable variation was observed for fruit yield per hectare varied from 39 to 144 tons, while the highest fruit yield per hectare was harvested from the germplasm viz., BD 7759B, BD 7757, BD 7751, BD 7301, QM, BD 7759A, BD 7762, QF, BD 7753, BD 8886, BD 10351, NL-1A, SLA-19. The number of locules, total soluble solids (TSS) and plant height at last harvest varied from 2 to 6.6, 2.6 to 5.9%, and 66 to 154cm, respectively. The TYLCV infection (%) and leaf-sucking pest infestation (%) were observed with a 1 to 20% range in the field condition in both cases. So, we can select that germplasm has zero per cent infestation. Considering the plant growth habit, earliness, different yield contributing horticultural traits, virus and pest infestation thirteen germplasm viz., BD 7759B, BD 7757, BD 7751, BD 7301, QM, BD 7759A, BD 7762, QF, BD 7753, BD 8886, BD 10351, NL-1A, SLA-19 were selected as breeding materials for further tomato improvement program. 展开更多

The carotenoid isomerase gene(BoaCRTISO)of Chinese kale was targeted and edited using the CRISPR/Cas9 system in the present study.The results showed a high mutation rate(81.25%),and 13 crtiso mutants were obtained.Only two types of mutations,insertions and replacements,were found.Both the total and individual carotenoid and chlorophyll concentrations of the biallelic and homozygous mutants were reduced,and the total levels declined by 11.89–36.33%.The color of the biallelic and homozygous mutants changed from green to yellow,likely reflecting a reduction in the color-masking effect of chlorophyll on carotenoids.The expression levels of most carotenoid and chlorophyll biosynthesis-related genes,including CRTISO,were notably lower in the mutants than in the WT plants.In addition,the functional differences between members of this gene family were discussed.In summary,these findings indicate that CRISPR/Cas9 is a promising technique for the quality improvement of Chinese kale and other Brassica vegetables. 展开更多

The combined application of organic and mineral fertilizers can be a proper way of nutrition management to increase the yield and quality and to mitigate environmental impacts of chemicals and the pertaining costs. The impact of different rates of sulfur-containing humic acid was studied on yield and nutrient uptake of the fruits of olive “Zard” three-year-old trees in a trial based on a Randomized Complete Block Design with three replications in Shariati College of Tehran, Iran. The studied treatment was sulfur-containing humic acid at four rates of 0, 20, 25 and 30 kg&sdot;ha&minus;1, which was applied at two stages. The highest fresh weight, dry weight, chlorophyll b, carotenoid, N and Cu contents were related to humic acid rate of 20 kg&sdot;ha&minus;1. The highest fruit length, chlorophyll a and total chlorophyll were observed in control. The highest K, Fe and Mn contents were obtained from plants treated with 30 kg&sdot;ha&minus;1 humic acid. Plants treated with 25 kg&sdot;ha&minus;1 exhibited the highest P and Zn contents. All in all, the application of sulfur-containing humic acid at different rates had favorable impacts on quantitative and qualitative traits of olive fruits. 展开更多

Huahui 1 is an elite transgenic male sterile restorer line of wild rice abortive-type that expresses a Bacillus thuringiensis (Bt) δ-endotoxin and provides effective and economic control oflepidopteran insects. To exploit Huahui 1 to develop a new Bt rice, the insertion site of the Bt gene was determined by thermal asymmetric interlaced PCR (TAIL-PCR). Bt was located in the promoter region ofLOC. Os10g10360, approximately 5.35 Mb from the telomere of the short arm of chromosome 10. For the first time, a Bt cytoplasmic male sterile (CMS) system was developed by introgressing Bt from Huahui 1. The recipient CMS system used consisted of Indonesia paddy rice-type II-32B (maintainer line) and II-32A (male sterile line). Marker-assisted selection was used to increase selection efficiency in the backcrossing program. In BC5F1, the Bt plant 85015-8 was selected for further analyses, as it had the highest SSR marker homozygosity. In addition, the linkage drag of the foreign Bt gene in 85015-8 was minimized to 8.01-11.46 Mb. The foreign Bt gene was then delivered from 85015-8 into II-32A. The resultant Bt II-32A and Bt II-32B lines were both resistant to lepidopteran in field trials, and agronomic traits were not disturbed. The maintainability of II-32B, and the male sterility and general combining ability of II-32A, were not affected by the Bt introgression. This study demonstrates a simple and fast approach to develop Bt hybrid rice. 展开更多

The study was conducted with 18 eggplant lines/variety at the farm of Olericulture Division, HRC, Bangladesh Agricultural Research Institute, Gazipur during the winter season of 2017-18 to develop new green type high yielding OP variety having tolerance to eggplant fruit and shoot borer and bacterial wilt. The lines varied significantly for their response to all characters (P SM 083F required minimum 105 days to first harvest. Maximum marketable fruit number was obtained by SM083A (30.33). Heavy sized fruit was harvested by SM275 (175 g), followed by SM289 (170 g), SM279 (169 g), SM083E (165 g), SM253 (164 g). The range of fruit infection by BFSB was 10.33% - 19.007%, while lowest in SM262 (10.33%). In case of bacterial wilt (BW) infestation at field level performance, zero percent incidence was observed in SM262, SM275, SM279, SM291B. The yield range of eggplant lines was 18.62 - 43.36 t/ha. The highest fruit yield was recorded from the line SM 275 (43.36 t/ha), which was statistically similar with which was statistically similar with SM 279 (39.85 t/ha), SM 291B (38.59 t/ha), SM083B (38.42 t/ha), SM 262 (38.17 t/ha), SM 253 (37.43 t/ha). Considering earliness, tolerance to fruit infection by BFSB, bacterial wilt infestation, attractive fruit shape and fruit colour, the lines SM 275, SM 279, SM 291B, SM083B, SM 262, SM 253 were found promising. So these six lines can be selected for further confirmation. 展开更多

The study took place at Bangladesh Agricultural Research Institute’s Olericulture Division’s research farm from March 2021 to February 2022 (BARI). In a protected net house, we investigated the impact of five different types of vegetables on various maturation stages, including tomato, broccoli, sweet pepper, cucumber, and netted melon. Vegetables cultivated under protected conditions in a transparent poly-film net house can improve quality, maturity, fruit size, and yield. When fruits and vegetables are picked before they are fully mature, they may stay green for longer, but they may not ripen to a satisfactory color and flavor, resulting in a loss of consumer confidence. Furthermore, because fruit continues to grow until the harvest, immature fruit will be smaller than mature fruit, reducing harvest yield. We tried to determine the right maturation stages in order to avoid product loss during our investigation. The tomato was found to be an appropriate size (6.5 cm length and 6.2 cm diameter), weight (84 g), TSS (4.5 percent), pH (4.3), “turning red”, and “tasty” at the week 5 stage, while the broccoli was found to be an appropriate size (12.0 cm length and 13.0 cm diameter), weight (360 g), and “green” color at the week 5 stage. At the week 6 stage, the nettled melon was found to be of appropriate size (15.2 cm length and 14.5 cm diameter), weight (800 g), TSS (10.8 percent), pH (6.3), “net fully developed” on the fruit skin and “much tasty,” while cucumber was found to be of appropriate size (8.8 - 10.8 cm length and 2.2 - 2.9 cm diameter), weight (61 - 88 g), TSS (3.8 - 4.1 percent), pH (6.3), “less powdery”. As a result, establishing the optimal maturity of our research will benefit both consumers and growers. 展开更多

The genetic architecture of yield was studied in a five parent half diallel cross of bottle gourd at the experimental field of Olericulture Division, Horticulture Research Centre (HRC), Bangladesh Agricultural Research Institute (BARI), Gazipur during the winter season of 2016-17. The values of mean square for GCA (general combining ability) and SCA (specific combining ability) were highly significant which suggested the presence of both additive and non-additive genetic variance in the population. But the higher magnitude of GCA compared to SCA indicated predominance of additive genetic variance. In most of the cases, the cross between poor and poor parents showed positive SCA effect for fruit yield, which indicated the higher yield. The estimates of mid parent heterosis ranged from &#8722;19.0 to 31.8 percent and the better parent heterosis ranged from &#8722;28.4 to 20.5 percent. Analysis for genetic components of variation suggested that additive components were more important in the inheritance of fruit yield. This character was observed being controlled by two to three pairs of genes or groups of genes. Narrow sense heritability was 55 percent indicating probability of selection in generations. The graphical analysis also indicated wide genetic diversity among the parents. 展开更多

The study was undertaken to identify the suitable mulch paper for different high-value vegetables during the winter season of November 2019 to March 2020 at the Olericulture research field of Bangladesh Agricultural Research Institute, Gazipur, Bangladesh. The study was a randomized complete block design with 3 replications. Four vegetable varieties viz., tomato, brinjal, capsicum and broccoli and 3 mulch treatments viz., T1 = Silver over black mulch;T2 = Black mulch;T3 = No mulch were included in this study. Different vegetables responded differently with the changes of mulches irrespective of different characters. it was clear that fruit number, average fruit weight, fruit length, fruit diameter were strongly related to soil moisture content. The effect of different plastic mulches on fruit weight per plant and yield (t/ha) was significant. Mulching produced higher fruit yield per plant and fruit yield per hectare than for the control, indicating that the mulch had a positive effect in generating increased fruit yield. Silver over black plastic mulch produced the highest fruit yield viz., 98.05 t/ha (tomato), 54.11 t/ha (brinjal), 34.33 t/ha (capsicum), 26.09 t/ha (broccoli) followed by black and no mulches, while the control plot produced the lowest fruit yield. 展开更多

Soil contamination by heavy metals is a serious environmental problem worldwide, and reduction of heavy metal accumulation in vegetables grown on contaminated land is a matter of urgency. A pot experiment was conducted to study the effects of intercropping with the Cd hyperaccumulators Solanum nigrum and Solanum photeinocarpum from two ecoclimatic regions, Ya'an and Chengdu, Sichuan Province, China, on the growth and cadmium (Cd) uptake of eggplant (Solanum melongena L.). The biomass, photosynthetic pigment contents, and activities of antioxidant enzymes of eggplant were enhanced by intercropping. The biomass of eggplant was the highest after intercropping with S. photeinocarpum from Ya'an, but did not differ significantly from that after intercropping with S. nigrum from Chengdu. The shoot Cd content of eggplant was significantly reduced by intercropping with the hyperaccumulators, which ranked as follows: S. nigrum from Chengdu 〉 S. nigrum from Ya'an 〉 S. photeinocarpum from Chengdu 〉 S. photeinocarpum from Ya'an, with the decreases being 19.60%, 14.36%, 9.66%, and 6.42%, respectively, as compared with the control. The lowest shoot Cd content and translocation factor of eggplant were attained after intercropping with S. nigvum from Chengdu. Therefore, it was feasible to intercrop eggplant with S. nigrum and S. photeinocarpurn on Cd-contaminated soil. 展开更多

Flavonoid biosynthetic genes are often coordinately regulated in a temporal manner during flower or fruit development, resulting in specific accumulation profiles of flavonoid compounds. R2R3-MYB-type transcription factors (TFs) "recruit" a set of biosynthetic genes to produce flavonoids, and, therefore, R2R3-MYBs are responsible for the coordinated expression of structural genes. Although a wealth of information regarding the identified and functionally characterized R2R3-MYBs that are involved in flavonoid accumulation is available to date, this is the first review on the global regulation of MYB factors in the flavonoid pathway. The data presented in this review demonstrate that anthocyanin, flavone/flavonol/3-deoxyflavonoid (FFD), proanthocyanidin (PA), and isoflavonoid are independently regulated by different subgroups of R2R3-MYBs. Furthermore, FFD-specific R2R3-MYBs have a preference for early biosynthetic genes (EBGs) as their target genes; anthocyanin-specific R2R3-MYBs from dicot species essentially regulate late biosynthetic genes (LBGs); the remaining R2R3-MYBs have a wider range of target gene specificity. To elucidate the nature of the differential target gene specificity between R2R3-MYBs, we analyzed the DNA binding domain (also termed the MYB-domain) of R2R3-MYBs and the distribution of the recognition cis-elements. We identified four conserved amino acid residues located in or just before helix-3 of dicot anthocyanin R2R3-MYBs that might account for the different recognition DNA sequence and subsequently the different target gene specificity to the remaining R2R3-MYB TFs. 展开更多

Plant metabolites are important for plant development and human health.Plants of celery(Apium graveolens L.)with different-colored petioles have been formed in the course of long-term evolution.However,the composition,content distribution,and mechanisms of accumulation of metabolites in different-colored petioles remain elusive.Using ultra-high performance liquid chromatography-tandem mass spectrometry(UHPLC-MS/MS),1159 metabolites,including 100 lipids,72 organic acids and derivatives,83 phenylpropanoids and polyketides,and several alkaloids and terpenoids,were quantified in four celery cultivars,each with a different petiole color.There were significant differences in the types and contents of metabolites in celery with different-colored petioles,with the most striking difference between green celery and purple celery,followed by white celery and green celery.Annotated analysis of metabolic pathways showed that the metabolites of the different-colored petioles were significantly enriched in biosynthetic pathways such as anthocyanin,flavonoid,and chlorophyll pathways,suggesting that these metabolic pathways may play a key role in determining petiole color in celery.The content of chlorophyll in green celery was significantly higher than that in other celery cultivars,yellow celery was rich in carotenoids,and the content of anthocyanin in purple celery was significantly higher than that in the other celery cultivars.The color of the celery petioles was significantly correlated with the content of related metabolites.Among the four celery cultivars,the metabolites of the anthocyanin biosynthesis pathway were enriched in purple celery.The results of quantitative real-time polymerase chain reaction(q RT-PCR)suggested that the differential expression of the chalcone synthase(CHS)gene in the anthocyanin biosynthesis pathway might affect the biosynthesis of anthocyanin in celery.In addition,HPLC analysis revealed that cyanidin is the main pigment in purple celery.This study explored the differences in the types and contents of metabolites in celery cultivars with different-colored petioles and identified key substances for color formation.The results provide a theoretical basis and technical support for genetic improvement of celery petiole color. 展开更多

Carotenoids are secondary metabolite responsible for colored pigments in plants and microbes(Li et al.,2022).They are a class of C40 tetraterpenoids consisting of eight isoprenoid units,and can be classified into carotenes and xanthophylls on the basis of their functional groups(Saini et al.,2015).Carotenes can be lin‐ear(phytoene,phytofluene,andζ-carotene)or branched(β-carotene andα-carotene).Xanthophylls compriseβ,β-xanthophylls(β-cryptoxanthin,zeaxanthin,violaxanthins,and neoxanthin)andβ,ε-xanthophylls(α-cryptoxanthin,α-carotene,and lutein). 展开更多
