The role of phospholipase A(2) in Arabidopsis root growth and microtubule organisation was investigated using a specific inhibitor, aristolochic acid. At 0.5-1.5 microm concentrations, this inhibitor reduced root elongation and caused radial swelling of the root tip. The normally transverse cortical
The WRKY family genes, which play an important role in plant morphogenesis and stress response, were selected based on the data of the full-length transcriptome of Asarum heterotropoides. Using AtWRKY33, which regulates the synthesis of the camalexin in the model plant Arabidopsis to compare
Phospholipase A(2) (PLA(2)) catalyses the hydrolysis of phospholipids into lysophospholipids and free fatty acids. Physiological studies have indicated that PLA(2) is involved in stomatal movement. However, genetic evidence of a role of PLA(2) in guard cell signalling has not yet been reported. To
