The B-box transcription factor BBX5 enhances UV-B resistance by promoting anthocyanin biosynthesis in Arabidopsis.

Ultraviolet-B (UV-B) light, a natural component of sunlight, plays a crucial role in the regulation of plant growth and development. B-box (BBX) proteins are zinc-finger transcription factors essential for plant growth, development, and responses to abiotic stress. The role of BBX5 in UV-B stress responses has not been previously identified.

Genome-wide analysis of autophagy-related genes in Medicago truncatula highlights their roles in seed development and response to drought stress.

Autophagy is a highly conserved process of degradation of cytoplasmic constituents in eukaryotes. It is involved in the growth and development of plants, as well as in biotic and abiotic stress response. Although autophagy-related (ATG) genes have been identified and characterized in many plant species, little is known about this process in Medicago truncatula.
