Molecular Basis of Wrinkled Pea Seed

In This Video you will learn about molecular explanation of wrinkled pea shape. During Mendel’s pea experiments, he noted that some varieties of peas had round seeds, while others had irregular wrinkled seeds. As a result of crossing these two pea variants, Mendel discovered that the round-seeded and wrinkled-seeded traits were two facets of the same character, suggesting to modern plant scientists that a single gene determines whether seeds are round or wrinkled. During the 1980s, John Innes Centre researchers began investigating the biochemical differences between round and wrinkled seeds. They discovered that the high sugar content in developing wrinkled seeds draws in large amounts of water through osmosis, causing the seed to swell. The seeds then lose volume as they mature and dry out to give a wrinkled appearance. #mendalianGenetics
