Metabolism As a Function of Water Potential in Air-Dry Seeds of Charlock (Sinapis arvensis L.).
A new method is described for studying the metabolism of air-dry seeds. An initial pulse of (14)CO(2) was supplied to seeds maintained in air at controlled low water potentials for 6 months. Seeds were also infiltrated with 2-(14)C-acetate and with (14)C-l-leucine at 0 C, redried rapidly at 0 C, and maintained at controlled low water potentials for 4 to 6 weeks. The metabolism of the air-dry se...
متن کاملDormancy in Seeds of Charlock (Sinapis arvensis L.): Early Effects of Gibberellic Acid on the Synthesis of Amino Acids and Proteins.
Charlock (Sinapis arvensis L.) seeds were imbibed with 10 mm GA(3) for 24 hours at 0 C. After equilibration at 25 C, a 5-fold increase in radioactivity in the amino acids labeled from 2-(14)C-acetate was observed within 2 hours. The total amount of amino acids was reduced to half, and the specific radioactivity increased approximately 10-fold, indicating a diversion of metabolites for amino aci...

15 صفحه اولSeed dormancy is modulated in recently evolved chlorsulfuron-resistant Turkish biotypes of wild mustard (Sinapis arvensis)
Biotypes of the broad-leaved wild mustard (Sinapis arvensis L.) found in wheat fields of Aegean and Marmara region of Turkey were characterized and shown to have developed resistance to sulfonylurea (chlorsulfuron), an inhibitor of acetolactate synthase (ALS). DNA sequence analysis of the ALS genes from two such resistant ("R") biotypes, KNF-R1 and KNF-R2, revealed point mutations, CCT (Pro 197...
