Influential Factors of Restorer of New Cytoplasmic Male Sterile(NER) on Anther Culture

Some influential factors of anther culture were studied preliminarily by conducting anther culture of the restorers of new cytoplasmic male sterile （NER）. Several results were obtain from this experiment and they were listed as follow：① MS cultrure medium with such hormones as 2,4-D 2 mg/L,6-BA 0.5 mg/L, NAA 0.5 mg/L was the best suitable for callus induction of NER. ②The difference of induction rate was significantly different between different plant age groups. From the 110th day to 141th day,the induction rate was increased with the increase of age and the difference of induction rate reached 0.01 significant difference level. The induction rate reached the highest value in the 141th day then it declined gradually. ③The combined use of 2, 4-D and 6-BA with proper increase of 2,4-D was good for inducing callus. ④The green plantlet induction rate of NER was increased when the concentration of 6-BA increased from 2 mg/L to 4 mg/L. Adding ZT from 0.5 mg/L to 2 mg/L. 6-BA would led 2.47% increase of green plantlet olantlet induction rate.

Establishment on Isolated Microspore Culture Optimized System for Restorer of New Cytoplasmic Male Sterile (NER) of Brassica napus L.

[Objective]The aim was to establish optimized system for NER isolated microspore culture of Brassica napus L.. [Method]Twenty varieties of NER of Brassica napus were grown under uncontrolled temperature and light conditions,and their isolated microspore from anthers were used as explants in vitro culture. The influencing factors of microspore culture were preliminarily studied. [Result]The difference of genotypes was important influencing factors to embryoid yield. The embryoid yield increased by supplementing with 6-BA and NAA,culturing in solid-liquid double layer medium with activated charcoal; The difference was not significant of embryoid yield between culturing in medium supplemented with colchicines and the CK. The rates of cotyledonous embryoids directly developed into normal plantlets increased through enriching with 0.1-0.2 mg/L NAA and being treated on slim illumination two days before being inducted into normal plantlets. [Conclusion]The technical system of microspore culture of restorer of new cytoplasmic male sterile （NER） was established,which and lays a foundation for accelerating genotype purification of NER introgressive line.

Size fractionated biomass and productivity of phytoplankton and new production in the Prydz Bay and the adjacent Indian sector of the Southern Ocean during the austral summer 1998/1999

The paper deals with the studies on the cell abundance, the composition of dominant species, size fractionated biomass and productivity of phytoplankton, new production, the environmentally restricted mechanism in the Prydz Bay and the adjacent Indian sector of the Southern Ocean during the austral summer 1998/1999. The results showed that there was marked feature of spatial zonation in the sea areas investigated. In the Prydz Bay and its adjacent continental shelf, the biomass and productivity of phytoplankton were high; those of continental slope and open ocean area were obviously low. The nutrient concentration had opposite distribution trend, due to the consumption of phytoplankton. It mainly affected by the vertical stability of water column, grazing pressure of zooplankton, temperature and light etc. The results of size-fractionation showed that the average contribution of netplankton to total chlorophyll a in studied sea areas was 52.2 %, those of nano- and picoplankton were 29.4 % and 18.4 %, respectively. The average contribution of netplankton to total primary production was 52.4 %, those of nano- and picoplankton were 28.7 % and 18.9 %, separately. It is same as previous conclusion that the contribution of picoplankton to productivity is slightly larger than that to biomass of phytoplankton communities. The average new production and f-ratio were 230.6 mg/ (m(2.)d) and 0.43, respectively.

A new species of Phyllochaetopterus Grube,1863(Polychaeta:Chaetopteridae)from Hainan Island,South China Sea

Abstract Phyllochaetopterus species are widely distributed on the coast of China. Here, Phyllochaetopterus hainanensis n. sp., a new species collected from Hainan Island （China）, is reported. It is characterized by having a V-shaped peristomium, two eyespots covered by a pair of large curved peristomial notopodia （cirri located beneath the palps）, 13-14 chaetigers in the anterior body region, with three enlarged modified chaetae on the fourth notopodium, and more than five chaetigers in the middle body region. The modified chaeta has a slightly inflated head with an obliquely truncate end. The new species resembles Phyllochaetopterus socialis Clapar6de, 1869, but differs in the shape of peristomial notopodia and peristomium. Twelve species of Phyllochaetopterus have been described from the Pacific Ocean, including the new species described here. An identification key to the known Pacific species is provided together with a brief discussion of the taxonomic value of the eyespots for the genus.

Autophagy inhibition: a new therapeutic target in spinal muscular atrophy

Spinal muscular atrophy（SMA）is a hereditary pediatric motor neuron（MN）disease：survival motor neuron 1（SMN1）gene mutation determines MN degeneration and,consequently,muscle atrophy,breathing and swallowing difficulties,and,in the most severe cases,premature death.A second unaffected gene（SMN2）is present,but it can only produce a limited amount of functional protein,modulating the disease severity and progression.

A new record from China of epiphytic marine algae,Acrochaete leptochaete(Chaetophoraceae,Chlorophyta)with its primary experimental biology

Acrochaete leptochaete, a species in Chaetophoraceae （Chlorophyta）, was observed during our recent laboratory culture of the macroalgae Chaetornorpha that was originally collected from an intertidal pool in Rongcheng, Shandong Province, China. This is the first record of this species in China. Its morphology, taxonomy, and distribution were introduced and discussed in detail. Isolated culture experiments at different temperatures （9-29℃） and light intensities （36-108 μmol/m^2.s） were also carried out. The culture-based observations have extended our knowledge of growth morphology and general biology of the species.
