Heat stress response and transposon control in plant shoot stem cells.

ABSTRACT: Plants have an impressive repertoire to react to stress conditions that limit regular growth. Elevated temperatures beyond the optimal range cause rapid and specific transcriptional responses, resulting in developmental alterations and plasticity. Heat stress also causes chromatin decondensation and activation of some transposable elements (TEs), endangering genomic integrity. This is especially risky for stem cells in the shoot apical meristem (SAM) that potentially contribute to the next generation. We examined how the heat stress response in SAM stem cells of Arabidopsis (Arabidopsis thaliana) is different from that in other tissues and whether the elements of epigenetic TE control active in the meristem are involved in specific heat protection of stem cells.
