In the absence of SAL1 or in response to drought and high light, PAP accumulates and can move between the chloroplast and the nucleus, where it inhibits exoribonucleases, thereby inducing stress-responsive genes.</p></abstract><abstract><p>Compartmentation of the eukaryotic cell requires a complex set of subcellular messages, including multiple retrograde signals from the chloroplast and mitochondria to the nucleus, to regulate gene expression. Here, we propose that one such signal is a phosphonucleotide (3′-phosphoadenosine 5′-phosphate [PAP]), which accumulates in <italic>Arabidopsis thaliana</italic> in response to drought and high light (HL) stress and that the enzyme SAL1 regulates its levels by dephosphorylating PAP to AMP. SAL1 accumulates in chloroplasts and mitochondria but not in the cytosol. <italic>sal1</italic> mutants accumulate 20-fold more PAP without a marked change in inositol phosphate levels, demonstrating that PAP is a primary in vivo substrate. Significantly, transgenic targeting of SAL1 to either the nucleus or chloroplast of <italic>sal1</italic> mutants lowers the total PAP levels and expression of the HL-inducible <italic>ASCORBATE PEROXIDASE2</italic> gene. This indicates that PAP must be able to move between cellular compartments. The mode of action for PAP could be inhibition of 5′ to 3′ exoribonucleases (XRNs), as SAL1 and the nuclear XRNs modulate the expression of a similar subset of HL and drought-inducible genes, <italic>sal1</italic> mutants accumulate XRN substrates, and PAP can inhibit yeast (<italic>Saccharomyces cerevisiae</italic>) XRNs. We propose a SAL1-PAP retrograde pathway that can alter nuclear gene expression during HL and drought stress.</p></abstract></article-meta></front></pmc></record>Pour manipuler ce document sous Unix (Dilib)
