Divergent evolution of genes in the genus : impacts of annuals and perennials' life history strategies.

Within the family , the genus is composed of two subgenera annuals (2n=40) and perennials. This life strategy transition may have differentially affected the evolution of various gene families. Its cultivated species has high level of susceptibility to major pathogens including viruses, bacteria and fungi.

Melatonin-Induced Protection Against Plant Abiotic Stress: Mechanisms and Prospects.

Global warming in this century increases incidences of various abiotic stresses restricting plant growth and productivity and posing a severe threat to global food production and security. The plant produces different osmolytes and hormones to combat the harmful effects of these abiotic stresses. Melatonin (MT) is a plant hormone that possesses excellent properties to improve plant performance under different abiotic stresses.
