Phytohormone Levels in Different Types of Symbiotic Mutants of Pea

Phytohormone Levels in Different Types of Symbiotic Mutants of Pea The levels of the phytohormones auxin and gibberellin were studied in the original pea (Pisum sativumL.) cultivars Rondo and Ramonskii 77 and in different types of symbiotic mutants (non-nodulating, with single nodules, and supernodulating) induced from them. The results obtained indicated that the levels of the phytohormones in the symbiotic mutants depend on the plant's genotype, developmental phase, and infection with rhizobia. Two mutants were isolated whose phytohormonal status markedly differed from the original forms. These mutants may be used for identification of the genes that determine the auxin and gibberellin statuses. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Journal of Genetics Springer Journals

Abstract

The levels of the phytohormones auxin and gibberellin were studied in the original pea (Pisum sativumL.) cultivars Rondo and Ramonskii 77 and in different types of symbiotic mutants (non-nodulating, with single nodules, and supernodulating) induced from them. The results obtained indicated that the levels of the phytohormones in the symbiotic mutants depend on the plant's genotype, developmental phase, and infection with rhizobia. Two mutants were isolated whose phytohormonal status markedly differed from the original forms. These mutants may be used for identification of the genes that determine the auxin and gibberellin statuses.
