Respostas bioquímicas e moleculares ao estresse por calor em culturas e plantas hortícolas

Autoria SCIMAGO INSTITUTIONS RANKINGS

Resumo

Vários estresses abióticos afetam o crescimento e desenvolvimento de plantas, sendo um deles responsável por severas perdas na produção de culturas e hortícolas no mundo, o estresse por calor. Nesse artigo, o efeito do estresse por calor (superior a 30-35 °C para diferentes espécies) em culturas e plantas hortícolas e seu efeito na indução de outros estresses, incluindo estresse osmótico e oxidativo são discutidos. As plantas demonstram respostas bioquímicas e moleculares após receberem sinais ambientais como altas temperaturas e toleram condições indesejáveis.
