RRFT1 (Redox Responsive Transcription Factor 1) is involved in extracellular ATP-regulated gene expression in Arabidopsis thaliana seedlings

As an apoplast signal molecule, extracellular ATP (eATP) is involved in the growth regulation of Arabidopsis thaliana seedlings. Recently, RRFT1 was revealed to be involved in eATP- regulated seedling growth. To further verify the role of RRTF1 in seedlings' eATP response, expression of 20 eATP...

Description
Summary:	As an apoplast signal molecule, extracellular ATP (eATP) is involved in the growth regulation of Arabidopsis thaliana seedlings. Recently, RRFT1 was revealed to be involved in eATP- regulated seedling growth. To further verify the role of RRTF1 in seedlings' eATP response, expression of 20 eATP-responsive genes in wild type (Col-0) and RRTF1 null mutant (rrtf1-1) seedlings were investigated by using realtime quantitative PCR. After 0.5 mM ATP stimulation, the response of these genes' expression in rrtf1-1 seedlings was significantly different from that in Col-0 seedlings. Proteins which are encoded by these genes include transcription factors, plasma membrane receptors like kinases, ion influx/efflux transporters and hormone signaling components. The results indicated that RRTF1 may be involved in eATP regulated physiological responses via regulating the expression of some functional genes.
