  Arabidopsis epidermal cell development is a model system for studying cell development, cell differentiation, and the cell cycle.Our previous studies have shown that the zinc finger protein GIS family genes, GIS, GIS2, and ZFP8, control shoot maturation and trichome initiation by integrating gibberellins and cytokinin signaling in Arabidopsis.

Recent evidence demonstrates that both copper amine oxidase (CuAO) and phospholipase D (PLD) are involved in abscisic acid (ABA)-induced stomatal closure.In this study, we investigated the interaction
Plant innate immunity generally consists of two branches, pathogen associated molecule patterns (PAMPs)-triggered innate immunity (PTI) and effector-triggered immunity (ETI).Significantly accumulating
Some of cellular components have been identified to function in abscisic acid (ABA) regulation of stomatal aperture, including calcium, cytoskeleton, phosphatidic acid (PA).In this study, phospholipas
Phototropins (photl and phot2) contribute redundantly to high-intensity blue light (HBL)-induced phototropic curvature of hypocotyls in Arabidopsis thaliana, which restricts the understanding of the m
The lipid-derived hormone jasmonic acid (JA) and structurally related jasmonates (collectively referred to as JAs) play essential roles in controlling plant defense, anthocyanin accumulation, trichome
Heterotrimeric G proteins have been shown to function as key players in hydrogen peroxide (H2O2) production in plant cells, and ethylene is known to induce stomatal closure via H2O2 generation, but wh
Lipid phosphate phosphatase (LPP) hydrolyzes diacylglycerol pyrophosphate (DGPP) to generate phosphatidic acid (PA) and PA to generate diacylglycerol (DAG), but more preference DGPP to PA.In Arabidops
The expression of genes encoding components of the ABA and metabolic signalling pathway in developing barley endosperm and embryo was investigated.The genes included HvRCAR35_47387 and HvRCAR35_2538 (
Phosphorus (P) is crucial nutrient element for crop growth and development.However, the network pathway regulating homeostasis of phosphate (Pi) in crops has many molecular breeding unknowns.Here, we
拟南芥表皮细胞是研究细胞发育、细胞分化和细胞周期的一个模型系统.我们以前的研究表明,锌指蛋白GIS家族基因,GIS、GIS2和ZFP8主要通过整合赤霉素和细胞分裂素的信号调控拟南芥表皮毛起始.最近,我们克隆了两个新的锌指蛋白基因ZFP5和ZFP6,它们通过不同的植物激素信号同时控制表皮毛和根毛细胞的起始和发育.我们试验结果表明它们主要在根特别是根毛细胞中表达.ZFP5和ZFP6基因突变主要表现导致
