　　Research Interests:

　　Modification of grass pea for food and feed applications. Grass pea ( Lathyrus sativus L.) is a very important potential crop in the arid and semiarid regions for its comparable protein content with soybean and more resistant to different biotic and abiotic stress under climate change and food security. However, incorporating grass pea as a major component in the diet is a challenge because the seed accumulates neurotoxic β-N-oxalyl-L-α,β-diaminopropionic acid (β-ODAP) and deficiency in sulfur-containing amino acids. Further, the presence of anti-nutritional factors such as trypsin inhibitor and elicitation of allergic reactions in susceptible individuals also disturb its utilization. The goal of our research program is to improve the overall quality of grass pea seed composition by molecular biological approaches.

　　Regulation mechanism of phyllotaxy formation. Phyllotaxy is a key feature of plant development and one of the most fascinating patterns in biology. It could also affect the output of grains like maize. It had been well known that plant hormones like auxin, cytokinin and gibberellins play important roles in phyllotaxy formation. At the same time, several key genes expression like PIN1 and KNOXI were verified playing roles in phyllotactic pattern and related to hormone accumulation and distribution. Recently, we obtained a tricussate whorled phyllotaxis mutant from gloxinia that do not harbor any other abnormal phenotype. The goal of our research program is to investigate the molecular mechanism of plant phyllotactic patterning.
