WRKY22 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 Ca2+-dependent protein kinase CPK3 is required for MAPK-independent salt-stress acclimation in Arabidopsis
Plants use different signalling pathways to respond to external stimuli. Intracellular signalling via calcium-dependent protein kinases (CDPKs) or mitogen-activated protein kinases (MAPKs) present two major pathways that are widely used to react to a changing environment. Both CDPK and MAPK pathways are known to be involved in the signalling of abiotic and biotic stresses in animal, yeast and p...
متن کاملSubmergence confers immunity mediated by the WRKY22 transcription factor in Arabidopsis.
Transcriptional control plays an important role in regulating submergence responses in plants. Although numerous genes are highly induced during hypoxia, their individual roles in hypoxic responses are still poorly understood. Here, we found that expression of genes that encode members of the WRKY transcription factor family was rapidly and strongly induced upon submergence in Arabidopsis thali...
متن کاملSTIFDB—Arabidopsis Stress Responsive Transcription Factor DataBase
Elucidating the key players of molecular mechanism that mediate the complex stress-responses in plants system is an important step to develop improved variety of stress tolerant crops. Understanding the effects of different types of biotic and abiotic stress is a rapidly emerging domain in the area of plant research to develop better, stress tolerant plants. Information about the transcription ...
متن کاملGene amplification from cryopreserved Arabidopsis thaliana shoot tips.
Cryopreservation is a way to store elite quality plant germplasms. The exact mechanism of stress tolerance during cryopreservation is unknown. Unavavailability of a detailed protocol for understanding the molecular genetics of plant cryostress is a major obstacle in plant cryobiology research. This paper describes the methods of extraction of total RNA from cryogenically stored plant tissues ac...
