TITTLE: Plant unique COST1 protein balances growth and stress tolerance via autophagy

ABSTRACT:

In plants, macroautophagy/autophagy has been reported to function in various biotic and abiotic stress-response pathways, but few direct regulators linking stress and autophagy have yet been identified. We recently identified a mutant, termed cost1 (Constitutively Stressed 1), which has strong drought tolerance with constitutive induction of autophagy and broad expression of normally stress-responsive genes. The COST1 protein negatively regulates autophagy by direct interaction with the key autophagy adaptor ATG8E, thus directly linking autophagy and drought tolerance. Moreover, plant growth and development in the cost1 mutant is greatly retarded, suggesting that COST1 controls the tradeoff between growth and stress tolerance.
