In a groundbreaking study, scientists from the Agharkar Research Institute (ARI) in Pune, India, collaborating with Savitribai Phule Pune University, have uncovered the genetic mechanisms responsible for seedlessness in grapes. Published on April 1 in the journal 'BMC Plant Biology', the research, led by Ravindra Patil, focuses on a seedless mutant derived from the high-yielding grape variety ARI-516. Through microscopic analysis, the team found that the mutant exhibited abnormal pollen structures and low viability, leading to complete failure of pollen germination, a critical factor in seedlessness. The study employed advanced transcriptomic and whole-genome sequencing analyses, revealing downregulated genes linked to pollen development and reproductive structures. Patil emphasized that the seedless trait is driven by pollen sterility and defects in reproductive development, resulting in parthenocarpy—fruit formation without fertilization. Prashant Dhakephalkar, director of ARI, noted that the identified genes could serve as molecular markers for developing superior seedless grape varieties, enhancing yield and adaptability.
