Soluble proteins and isoenzymes from seeds of diverse male steriles of sorghum, (Sorghum bicolor (L.) Moench)

Abstract

A comparison of soluble protein, esterase, GDH and ADH isoenzyme patterns in seeds of different steriles, maintainers and restorer lines exhibited similarities as well as differences. Soluble protein patterns from sterile and maintainer lines differed both qualitatively and quantitatively. Based on the esterase patterns, male steriles with different cytoplasms could be separated into three groups (i) Ck 60A and B; Nagpur A and B, (ii) M 35-1A and 1 B, M 31-2A and 2B, (iii) G1A and B, VZM2A and 2B. Each group could further be differentiated on the basis of minor differences in esterase isoenzyme patterns within each group. ADH and GDH patterns in general were similar in both sterile and maintainer lines.

THE RELATIONSHIP BETWEEN MALE STERILITY AND MEMBRANE LIPID PEROXIDATION AND ANTIOXIDANT ENZYMES IN WHEAT (Triticum aestivum L.)

“…IAA content is closely related to the accumulation of nutrients in anther. Higher POD activity in sterile lines can lead to the IAA greatly decomposition and oxidation, which causing IAA deficiency in the process of male organ development and causing a further substance metabolism disorder, energy loss, leading to the occurrence of male sterility (Banga et al, 1984;Tripathi et al, 1983). In this study, the POD activity was always higher than NW in PMS, which was consistent with the above research results of IAA deficiency leading to the occurrence of male sterility.…”

“…Tripathi et al (1983) compared total protein, esterase, alcohol dehdrogenase, and glutamate dehydrogenase patterns from seed extracts of male sterile, maintainor, and restorer lines of S. bicolor. Variability was seen in esterase patterns.…”
