Leaves are one of the organs involved in plant assimilation and transpiration. Different leaf development processes can result different shapes. Tomato plants have typical compound leaves. It is helpful to explore regulatory factors affecting morphogenesis tomatoes cultivate varieties with high photosynthetic efficiency. We used tomato shape mutants Petroselinum (Pts), Trifoliate (tf2), Entire ...

Here, we characterize a plastidial thioredoxin (TRX) isoform from Arabidopsis thaliana that defines a previously unknown branch of plastidial TRXs lying between x- and y-type TRXs and thus was named TRX z. An Arabidopsis knockout mutant of TRX z had a severe albino phenotype and was inhibited in chloroplast development. Quantitative real-time RT-PCR analysis of the mutant suggested that the exp...

Plant-specific NAC transcription factors (TFs) constitute a large family and play important roles in regulating plant developmental processes and responses to environmental stresses, but only some of them have been investigated for effects on disease reaction in cereal crops. Virus-induced gene silencing (VIGS) is an effective strategy for rapid functional analysis of genes in plant tissues. In...

In plants, resistance (R) gene-mediated defense confers resistance to a specific pest or pathogen following recognition of their avirulence (Avr) effectors. R-Avr mediated resistance is often conferred by a hypersensitive response that results in localized cell death at the infection site which starves the pathogen or pest. Mi-1 is a tomato R gene that confers resistance to rootknot nematodes, ...

Brassinosteroids (BRs), plant steroid hormones, play essential roles in modulating cell elongation, vascular differentiation, senescence, and stress responses. However, the mechanisms by which BRs regulate plant mitochondria and resistance to abiotic stress remain largely unclear. Mitochondrial alternative oxidase (AOX) is involved in the plant response to a variety of environmental stresses. I...
