Abstract

<div class="line" id="line-15"> Developing a robust root system is crucial to plant survival and competition for soil resources. Here we report that the non&hyphen;specific phospholipase C 5 (NPC5 ) and its derived lipid mediator diacylglycerol (DAG ) mediate lateral root (LR ) development during salt stress in  A rabidopsis thaliana  . T&hyphen;DNA knockout mutant  npc5&hyphen;1  produced few to no LR under mild NaCl stress, whereas overexpression of  NPC 5  increased LR number. Roots of  npc5&hyphen;1  contained a lower level of DAG than wild type, whereas  NPC 5  overexpressor exhibited an increase in DAG level. Application of DAG , but not phosphatidic acid, fully restored LR growth of  npc5&hyphen;1  to that of wild type under NaCl stress.  NPC 5  expression was significantly induced in Arabidopsis seedlings treated with NaCl .  Npc 5&hyphen;1  was less responsive to auxin&hyphen;mediated root growth than the wild type. These results indicate that NPC 5 mediates LR development in response to salt stress and suggest that DAG functions as a lipid mediator in the stress signalling. </div>
