Light significantly influences plant stress responses, with chloroplasts playing a pivotal role as both energy providers and light sensors. They communicate the nucleus through retrograde signals, including secondary metabolites reactive oxygen species (ROS). To investigate contribution of chloroplast redox biochemistry to biotic we studied interactions tobacco leaves expressing alternative electron shuttle flavodoxin virulent nonhost Pseudomonas syringae pathovars under dark conditions....
Tomato is the most important horticultural crop worldwide. Domestication has led to selection of highly fruited genotypes, and harvest index (HI), defined as ratio fruit yield over total plant biomass, usually employed a biomarker agronomic value. Improvement HI might then result from increased production and/or lower vegetative growth. Reduction in biomass been accomplished various species by expression flavodoxin, an electron shuttle flavoprotein that interacts with redox-based pathways...
Water limitation represents the main environmental constraint affecting crop yield worldwide. Photosynthesis is a primary drought target, resulting in over-reduction of photosynthetic electron transport chain and increased production reactive oxygen species plastids. Manipulation chloroplast distribution by introducing alternative sinks has been shown to increase plant tolerance multiple challenges including hydric stress, suggesting that similar strategy could be used improve crops. We show...
Foliar development involves successive phases of cell proliferation and expansion that determine the final leaf size, is characterized by an early burst reactive oxygen species generated in photosynthetic electron transport chain (PETC). Introduction alternative PETC acceptor flavodoxin tobacco chloroplasts led to a reduction size associated lower expansion, without affecting number per leaf. Proteomic analysis showed biogenesis proceeded stepwise wild-type leaves, with accumulation...
