Accumulation of storage proteins in plant seeds is ...

Amyloids of Vicilin resist digestion by gastrointestinal enzymes, persist in canned peas, and exhibit toxicity for yeast and mammalian cells. Our finding for the first time reveals involvement of amyloid formation in the accumulation of storage proteins in plant seeds.

Jul 23, 2020  The storage proteins form aggregates resistant to treatment with ionic detergents in pea seeds. Resistance to treatment with ionic detergents is a typical feature of amyloids, discriminating them from the majority of other nonamyloid protein complexes [].We decided to study whether storage proteins form detergent-resistant aggregates in plant seeds.
