The RAV1 transcription factor positively regulates leaf senescence in Arabidopsis
Leaf senescence is a developmentally programmed cell death process that constitutes the final step of leaf development and involves the extensive reprogramming of gene expression. Despite the importance of senescence in plants, the underlying regulatory mechanisms are not well understood. This study reports the isolation and functional analysis of RAV1, which encodes a RAV family transcription ...
متن کاملWRKY22 transcription factor mediates dark-induced leaf senescence in Arabidopsis.
Arabidopsis WRKY proteins are plant-specific transcription factors, encoded by a large gene family, which contain the highly conserved amino acid sequence WRKYGQK and the zinc-finger-like motifs, Cys(2)His(2) or Cys(2)HisCys. They can recognize and bind the TTGAC(C/T) W-box ciselements found in the promoters of target genes, and are involved in the regulation of gene expression during pathogen ...
متن کاملThe Dof transcription factor OBP3 modulates phytochrome and cryptochrome signaling in Arabidopsis.
Plants perceive subtle changes in light quality and quantity through a set of photoreceptors, including phytochromes and cryptochromes. Upon perception, these photoreceptors initiate signal transduction pathways leading to photomorphogenic changes in development. Using activation-tagging mutagenesis to identify novel light-signaling components, we have isolated a gain-of-function mutant, sob1-D...
متن کاملA Dof Transcription Factor, SCAP1, Is Essential for the Development of Functional Stomata in Arabidopsis
Stomata are highly specialized organs that consist of pairs of guard cells and regulate gas and water vapor exchange in plants [1-3]. Although early stages of guard cell differentiation have been described [4-10] and were interpreted in analogy to processes of cell type differentiation in animals [11], the downstream development of functional stomatal guard cells remains poorly understood. We h...
متن کاملThe Arabidopsis transcription factor WRKY27 influences wilt disease symptom development caused by Ralstonia solanacearum.
WRKY transcription factors play a key role in modulating the plant defense transcriptome. Here we show that the Arabidopsis mutant wrky27-1, which lacks a functional WRKY27 transcription factor, showed delayed symptom development in response to the bacterial wilt pathogen Ralstonia solanacearum. Additionally, wrky27-1 plants did not express PR marker genes upon infection, as also observed in re...
