FREE AMINO ACID DIFFERENCES BETWEEN CYTOPLASMIC MALE STERILE AND NORMAL FERTILE ANTHERS

Comparative Analyses of Some of the Free Amino Acids in Anthers of Fertile and Genetic Cytoplasmic Male Sterile Sorghum.

ENETIC cytoplasmic male sterility in Sorghum is fundamentally an aspect of the problem of gene action and nuclear-cytoplasmic interaction. Our interest in the problem stems not from a concern with the practical use so effectively being made of the failure of certain lines to produce functional pollen but rather from a desire to know more about the basic components of this process as an example ...

Differential Proteomic Analysis of Anthers between Cytoplasmic Male Sterile and Maintainer Lines in Capsicum annuum L

Cytoplasmic male sterility (CMS), widely used in the production of hybrid seeds, is a maternally inherited trait resulting in a failure to produce functional pollen. In order to identify some specific proteins associated with CMS in pepper, two-dimensional gel electrophoresis (2-DE) was applied to proteomic analysis of anthers/buds between a CMS line (designated NA3) and its maintainer (designa...

Proteolytic activity in anther extracts of fertile and cytoplasmic male sterile petunia.

Proteolytic activity is compared in anther extracts from Petunia parodii fertile and cytoplasmic male sterile lines. It is characterized relative to developmental stage of the anthers, effect of variable incubation times, pH of isolation buffers, and degradation of marker proteins. In fertile anthers, proteolytic activity increases at the end of microsporogenesis and peaks early in microgametog...

Callus Formation and Differentiation in Tissue Cultures of Normal and Texas Cytoplasmic Male-Sterile Corn

Comparative Transcriptome Profile of the Cytoplasmic Male Sterile and Fertile Floral Buds of Radish (Raphanus sativus L.)

Radish cytoplasmic male sterility (CMS) has been widely used for breeding in Raphanus and Brassica genera. However, the detailed regulation network of the male sterility remains to be determined. Our previous work has shown that the abnormalities in a CMS radish appeared shortly after the tetrad stage when microspores were malformed and the tapetal cells grew abnormally large. In this work, his...
