S.  aPlant small heat shock proteins and its interactions with biotic stress.h[electronic resource]  c2016  ap. 19-39. v. 10.  vv. 10.  aSmall heat shock proteins were first identified during heat shock stress, but currently have been often associated to plant biotic stresses. Considered stress defense proteins, HSP20s functions are especially related to interact with unfolded model substrate proteins, in ATP-independent manner, and keep them in a folding-competent state for subsequent refolding. These proteins have been reported to serve a role in plant-response against the most important crop phytopathogens in the world, such as nematodes and fungi. Their activation role during biotic stress is not completely elucidated, but some researches have demonstrated that in some occurrences of plant response to biotic stresses, there is a crosstalk between the abiotic stress responses. Some genetic evidence has revealed that the chaperones play a critical role in plant immunity. One hypothesis is the chaperone activity can provide the stability and accumulation of R proteins, and thus for the entire defense signaling cascade coordination. However, the researches about this issue still need to better elucidate HSP20 pathways and function in plant biotic stress.  abiotic stress  aEstresse biótico1 aSILVA, S. M.
