Abstract:

The sexual reproduction in flowering plants is highly sensitive to hot or cold temperature stresses, thus temperature is fatal to reproductive success. This review describes studies of temperature stress on plant sexual reproductions, which suggests that pollen development may be the most sensitive reproductive stage. Transcriptome and proteomic studies shows that the genes including calmodulin, calcium dependent protein kinase 2, HSFs, and HSPs, might be involved in heat stress response pathways that function during pollen development. Understanding how plants cope with stress during reproductive development provides the oppotunity to identify genetic traits that can improve temperature tolerance in selected crop breeding and agronomic plants by genetic engineering.

Key words: Cold stress, Fertilization, Gene expression, Heat stress, Plant sexual reproduction, Pollen
