The Language of Ornaments:An Anthropological Insight Into the Ethnic Ornaments of the Karbis of Assam,India

North Eastern region of India enjoys a place of pride in the whole of the country for its immensely rich assembly of tribal cultures.Among the prominent tribes of the region are the Karbis who possess unique traditions and cultures distinct from the other tribes.The Karbis are fond of ornaments and since the ancient day they have been using natural objects as ornaments,silver ornaments are used extensively by them.Preparation of different kinds of ornaments occupies an important part of material culture of the Karbis.Ornaments with distinctive colour,motifs,and designs not only reflect the cultural identity of the Karbis but are also indicative of the possession of rich cultural heritage and traditional knowledge.In this present endeavour,an attempt has been made to delineate the ethnic ornaments of the Karbis of Assam,India,along with the motifs of the designs in it which stands as one of the integral aspects of their cultural heritage.

Designing of future ornamental crops: a biotechnological driven perspective

With a basis in human appreciation of beauty and aesthetic values,the new era of ornamental crops is based on implementing innovative technologies and transforming symbols into tangible assets.Recent advances in plant biotechnology have attracted considerable scientific and industrial interest,particularly in terms ofmodifying desired plant traits and developing future ornamental crops.By utilizing omics approaches,genomic data,genetic engineering,and gene editing tools,scientists have successively explored the underlying molecular mechanism and potential gene(s)behind trait regulation such as floral induction,plant architecture,stress resistance,plasticity,adaptation,and phytoremediation in ornamental crop species.These signs of progress lay a theoretical and practical foundation for designing and enhancing the efficiency of ornamental plants for a wide range of applications.In this review,we briefly summarized the existing literature and advances in biotechnological approaches for the improvement of vital traits in ornamental plants.The future ornamental plants,such as light-emitting plants,biotic/abiotic stress detectors,and pollution abatement,and the introduction of new ornamental varieties via domestication of wild species are also discussed.

High-throughput discovery of plastid genes causing albino phenotypes in ornamental chimeric plants

Chimeric plants composed of green and albino tissues have great ornamental value.To unveil the functional genes responsible for albino phenotypes in chimeric plants,we inspected the complete plastid genomes(plastomes)in green and albino leaf tissues from 23 ornamental chimeric plants belonging to 20 species,including monocots,dicots,and gymnosperms.In nine chimeric plants,plastomes were identical between green and albino tissues.Meanwhile,another 14 chimeric plants were heteroplasmic,showing a mutation between green and albino tissues.We identified 14 different point mutations in eight functional plastid genes related to plastid-encoded RNA polymerase(rpo)or photosystems which caused albinism in the chimeric plants.Among them,12 were deleterious mutations in the target genes,in which early termination appeared due to small deletion-mediated frameshift or single nucleotide substitution.Another was single nucleotide substitution in an intron of the ycf3 and the other was a missense mutation in coding region of the rpoC2 gene.We inspected chlorophyll structure,protein functional model of the rpoC2,and expression levels of the related genes in green and albino tissues of Reynoutria japonica.A single amino acid change,histidine-to-proline substitution,in the rpoC2 protein may destabilize the peripheral helix of plastid-encoded RNA polymerase,impairing the biosynthesis of the photosynthesis system in the albino tissue of R.japonica chimera plant.

Seed Morphology and Seedling Variation of Four Ornamental Lupin Pedigrees

[Objective] This study was conducted to reveal seed characteristics, variation and their effects on seedling growth of ornamental lupins. [Method] The phenotypic characteristics and germination rate of the seeds of four excellent lupin pedigrees were measured, and then their correlations with seeding growth were analyzed. [Result] There were abundant variations among the four ornamental lupin pedigrees. Pink seeds had the largest volume and red seeds had the largest 1 000seed weight. The variation coefficients for the seed morphological traits among the four pedigrees ranged from 2.97% to 14.34%. Seed specific weight and 1 000-seed weight could be used as important indicators for selection in breeding because of their higher variability. Seed weight variation of ornamental lupin was mainly depen- dent on seed width variation. There was small variation in seed length. The seeds of the four ornamental lupin pedigrees started to germinate one day after sowing, and the germination period was 5 d. Germination rate coefficient and germination index of pink and red seeds were higher than those of blue seeds, but blue seeds had the largest germination rate. 1 000-seed weight shared significantly positive correlations with seed germination rate, germination potential and seedling retention rate. Round and large seeds had some advantages in germination. Full seeds had higher germination rate and speed, and seedling retention rate. There was a significant relationship between seed length-width ratio and the number of leaflets of seedlings. [Conclusion] The results provided references for the evaluation of seed phenotypic diversity and breeding research of ornamental lupins.

Effect of LaCl_3 on Resistance and Absorptive Capacity to Formaldehyde of Indoor Ornamental Plants under Formaldehyde Stress

[Objective] This study aimed to determine the effect of rare earth biological regulator LaCl3 on the absorptive capacity to formaldehyde of four indoor ornamental plants, and to screen out the plant whose absorptive capacity to formaldehyde can be increased most greatly by LaCl3. [Method] Effect of LaCl3 on absorptive capacity to formaldehyde of four indoor ornamental plants was studied through fumigating in laboratory. Simultaneously, the indoor ornamental plant, which could significantly en- hance the degradation capacity of formaldehyde, was screened out to study the physiological and biochemical mechanisms of formaldehyde resistance. [Result] The ability to absorb formaldehyde of four indoor ornamental plants was enhanced by dif- ferent ranges after spraying with LaCl3 at suitable concentrations. The ability to ab- sorb formaldehyde of Hedera nepalensis var. sinensis, Chlorophytum comosum, Scindapsus aureun and Sansevieria trifasciata increased by 15.16%, 4.72%, 19.75% and 7.68%, respectively. In the four indoor ornamental plants, the capacity of S. au- reun to absorb formaldehyde was greatly improved by spraying LaCl3. When S. au- reun was stressed by formaldehyde, its chlorophyll content decreased by 39.87%, membrane permeability, MDA accumulation and POD activity increased by 8.17%, 56.92%, and 11.32%, respectively. However, compared the pre-spraying group with the no-spraying group under formaldehyde stress, chlorophyll content of S. aureun reduced less, membrane permeability and MDA cumulative both increased less, but POD activity increased more. [Conclusion] The formaldehyde absorption capacity of S. aureun was mostly improved after LaCl3 was sprayed.
