Gibberellins (GA) has diverse effects on plant growth and development including seed germination, leaf expansion, hypocotyls and stem elongation, and flower initiation etc. We are interested in the molecular mechanism controlling plant growth and flowering underlying GA signaling in plants. We use the Arabidopsis and rice as model plants; carry our screens for new mutants based on the repressing/suppressing for GA responses, which will identify genes encoding proteins required for GA signaling. We are using genetic, molecular and biochemical approaches to investigate the functions of their encoded products, to gain an understanding of the mechanism of GA-mediated growth in Arabidopsis growth and GA-mediated induction of α-amylase activity in rice.

Investigation of biochemical processes and regulatory mechanisms underlying the adaptation to low nitrogen (N) can aid in understanding how N is used efficiently in plants. Recent studies have uncovered the involvement of multiple biological processes in plant adjustment to low N. The altered response to low N stress of the T-DNA mutant of folylpolyglutamate synthetase gene was observed. The mutant seedlings failed to establish an adaptive response to N limitation and had shorter primary roots, more anthocyanins, starch, and amino acids, but fewer fresh weight, soluble protein, fructose, and glucose as compared to wild-type (WT) seedlings with low nitrate. Gene expression studies in low nitrate-treated seedlings revealed decreased transcripts for a number of genes involved in folate biosynthesis and N metabolism. In addition, the mutant had higher nitrate reduction ability and lower activity of glutamine synthetase than the WT, implying that N assimilation under N limitation was drastically perturbed because of a loss of function. These results indicate that folylpolyglutamate synthetase gene is required for adaptation to N limitation in Arabidopsis and provide a new insight into a potential interaction between folate and N metabolism.

We have three major lines of research: methylation of phytohormones, molecular mechanisms of leaf flatness, branching and gametogenesis, and genetic analysis of rice resistance against rice blast fungal disease.

Plant hormones are essential for many aspects during development. The homeostasis of phytohormones are regulated by many interacting pathways including de novo biosynthesis, degradation and disactivation by forming conjugates. We intend to study, at both the molecular and cellular level, the role of a newly found modification, methylation, of the phytohormones in plant development, so that new layers of understanding would be added to the complexity of regulation of the phytohormone activities. Meanwhile, we are also interested in dissecting the molecular mechanisms behind specific developmental processes, including leaf flatness, branching and gametogenesis in Arabidopsis by analyzing loss-of-function mutants. In addition to Arabidopsis, we also pay attention to the molecular mechanisms involved in the emergence, maintenance and evolution of the resistance of rice plants, a monocot model plant, to the fungal blast disease.

Cristobal Uauy 【吴为, JIC】
Our work seeks to identify genes underlying wheat QTL with significant agronomic impact and facilitate their effective deployment into modern breeding varieties. Using map-based cloning we have been able to identify genes that determine QTL for complex traits such as senescence and grain nutrient content (Uauy et al. 2006) as well as broad-race resistance to stripe rust (Uauy et al. 2005; Fu et al. 2009). In addition we have developed two TILLING populations in tetraploid and hexaploid wheat as reverse genetics resource that will hopefully enable more researchers to pursue wheat functional genomics and provide novel allelic diversity for wheat improvement (work done with Jorge Dubcovsky and Luca Comai at UC Davis).
