GBSS1 (Granule-bound starch synthase1) controls amylose synthesis in all cereals.Previous reports on its regulation have been primarily focused on its transcriptional and post-transcriptional levels.I
By investigating on the specific field observation and breeding cultivation of an unique endangered plant (Begonia fimbristipula Hance) in Dinghushan Mountain, Guangdong Province, its cross-breeding i
Drought poses a serious threat to the sustainability of rice (Oryza sativa) yields in rain-fed agriculture.The bHLH transcription factors play important roles in the regulation of plant development an
Long-chain acyl-Coenzyme A (CoA) synthetases (LACSs) catalyze the formation of long-chain acyl-CoA which play important roles in fatty acid metabolism, including phospholipids, triacylglycerol (TAG) b
温敏雄性不育(temperature sensitive male sterility,MS)在现代杂交水稻培育方面起着举足轻重的作用。为了探究植物温敏雄性不育的分子机制,我实验室通过EMS诱变野生型拟南芥Col-0,获得了一株温敏雄性不育突变体,该突变体表现为16℃可育,23℃半不育,27℃完全不育。通过图位克隆,发现该突变体突变基因为a tms1,为单碱基突变,其编码一个脂酰辅酶A合成酶。采用
The moss Physcomitrella patens is an ideal model plant to study plant developmental processes.To better understand the mechanism of protoplast regeneration, we have carried out cellular and phosphopro
In Arabidopsis, the roles of the NIPs in the arsenite distribution in plants remain poorly understood.Here, we report that Arabidopsis NIP3;1 and NIP 1;1 play different major roles in the shoot and ro
The continuing rise in atmospheric CO2 causes closing of stomatal pores and regulates stomatal development, and thus globally regulates plant water loss, CO2 influx and water use efficiency.But this C
LST8 (GβL) negatively regulates amino acid biosynthesis as a component of the TOR pathway in yeast.There are two homologs of LST8 in Arabidopsis, AtLST8.1 (At2g22040) and AtLST8.2 (At3g18140).Here we
植物氨基酸转运载体(amino acid transporter,AAT)是负责氨基酸跨膜运输的膜蛋白,在植物生长发育过程中起着十分重要的作用。通过异源表达分析等方法,在拟南芥中已经至少鉴定出60个AAT基因,其中许多基因的功能也被揭示。但是,到目前为止,水稻基因组中AAT基因的数量、种类及其生物学功能仍然不十分清楚。
