Abstract

An auxin autotrophic Arachis hypogea cell culture was sensitive to stress treatments leading to water loss whereas the growth of its auxin-supplemented counterpart was unaffected under similar conditions. Here we show that an hour of transient auxin treatment in the post stress period was sufficient for restoring the auxin autotrophic growth potential of the stress driven quiescent Arachis cells. Qualitative proteome analysis revealed protein turnover to have a role in mediating auxin-originated signals in these cells. In consonance, MG132 a cell permeable inhibitor of the ubiquitin mediated protein turnover completely inhibited the auxin dependent growth restoration of the stressed Arachis cells. Thus protein turnover is a necessary downstream event in exogenous auxin mediated stress tolerance in Arachis cells.
