Ca2 + 信使系统是植物体内重要的信号通路 ,它将许多细胞外信号转化为细胞内的信号以影响许多蛋白激酶活性 ,从而引起植物生长发育的多种反应 .在正常Ca2 + 浓度下 ,仅激素处理不能生根的丝瓜外植体 ,处以不同Ca2 + 浓度处理时 ,随Ca2 + 浓度升高 ,外植体生根数明显加快并增多 ,且有少量植株叶腋处异化生根 ,在一定程度上改变了腋芽的发育方向 ,这说明Ca2 + 改变了卷须芽或花芽的
Studies of the living embryo sacs of Torenia fournieri reveal that the actin cytoskeleton undergoes dramatic changes that correlate with nuclear migration within the central cell and the primary endos
Detailed observation of the microstructural features of 11 fault gouge and 3 fault breccia samples collected from Tianjingshan-Xiangshan fault zone has revealed that fault gouge can be classified into
Two contrasting barley (Hordeum vulgare L.) cultivars: Kepin No.7 (salt sensitive), and Jian 4 (salt tolerant) were grown hydroponically to investigate the microdistribution of mineral ions in roots a
Relativistic (E>1.6 MeV) electron flux enhancements during Solar Energetic Particle (SEP) events as observed by the synchronous FY-2 satellite at orbit located at 105° E are investigated. Energetic pr
Acid invertase (EC 3.2.1.26) is one of the key enzymes involved in the carbohydrate sink-organ development and the sink strength modulation in crops. The experiment conducted with Starkrimson apple (M
We recognized 6 sets of reflecting P- and S-wave events from Mono and other interfaces within the crust, respectively, with the wide-angle seismic data acquired from 510 km-long Selincuo-Yaanduo profi
Cold-active enzymes have received little research attention although they are very useful in industries. Since the structure bases of cold adaptation of enzymes are still unclear, it is also very diff
The Canglangpu Stage of Lower Cambrian Series is widely distributed along both sides of the Tanlu (Tancheng-Lujiang) Fault Zone in the Jiao-Liao-Xu-Huai regions. In the Liaodong Peninsula, the Canglan
Jasmonates are a new class of plant hormones that play important roles in plant development and plant defense. The COI1 gene was previously shown to be required for jasmonate-regulated plant fertility
