SCIENCE AND TECHNOLOGY
Architect of Pollen development & Seed formation identified

• Scientists have identified a novel gene that plays a crucial role in the development of stamens (male reproductive structure) including pollen grain and seed formation, in Arabidopsis flowering plants related to cabbage and mustard. The study opens up new possibilities for improving crop fertility and seed production.
• Pollen formation represents a very important developmental stage in plant life cycle. It represents the male gametophyte and its role is to deliver the genetic material to the embryo sac.
• The production and transfer of viable pollen grains to the stigma, germination of the pollen grains, growth of the pollen tubes down the style, and effective fertilization are necessary for the formation of a successful seed set. Thus, understanding the pollen development process not only elucidate the basic mechanism of sexual reproduction of flowering plants but also add valuable information for subsequent manipulation in crop production.
• Recent investigations on pollen development by Prof. Shubho Chaudhuri’s lab at Bose Institute, Kolkata, an autonomous institution of Department of Science and Technology, identified a novel gene named HMGB15, a non-histone protein that restructures chromatin, plays a crucial role in the development of stamens (male reproductive structure) in ArabidopsiS.
• Molecular analysis indicated that several developmental pathways like biosynthesis of phytohormone jasmonic acid (JA), apoptosis of tapetal cells and actin polymerization dynamics have been severely affected in the HMGB15 loss of function mutants.

SPORTS
Harbhajan & Sania Mirza Named Dubai Sports Council Ambassadors

• The Dubai Sports Council has appointed four global sports icons as its Sports Ambassadors, including former Indian cricketer Harbhajan Singh and renowned tennis player Sania Mirza.
• This initiative aims to enhance Dubai’s reputation as a global sports destination and strengthen its sports ecosystem by attracting prestigious international events, nurturing local talent, and promoting sports tourism.
• Promote Dubai as a premier sports destination globally.
• Strengthen Dubai’s sports ecosystem through the attraction of international events.
• Support local talent development and encourage sports tourism.
