Genome-Wide Identification of Myb Gene Family Reveals Potential Members Involved in High-Temperature Stress in Gracilariopsis Lemaneiformis

Researchers at Ningbo University have made a groundbreaking discovery in the field of cancer research, identifying 18 Myb gene family members in the economically important red alga Gracilariopsis lemaneiformis. The study, published in Marine Biotechnology, reveals that these genes play a crucial role in high-temperature stress, salicylic acid, methyl jasmonate, and abscisic acid responses in the alga.

The research team, led by Nianjun Xu, used genome-wide identification and expression analysis to identify the Myb gene family in G. lemaneiformis. They found that 15 of these genes were induced under high-temperature stress, with GlMYB3, GlMYB4, GlMYB8, GlMYB9, and GlMYB15 being the most significantly induced. Furthermore, GlMYB4 was found to possess transactivation activity and interact with three candidate proteins, CNB, OGT, and CPSF, to modulate high-temperature tolerance.

The discovery of these genes and their functions has significant implications for the development of new varieties of the alga with stable traits and heat tolerance. The research has also shed light on the potential use of these genes in biotechnology applications, such as the production of biofuels and other valuable compounds.
