Analysis of flavonoids in pubescence of soybean near-isogenic lines for pubescence color loci

Article Abstract:

A study was conducted to investigate the nature of flavonoids in the pubescence of near-isogenic lines (NILs) for the loci by extracting flavonoids with methanol from pubescence of cultivar Clark. The results suggested that Td loci may encode a structural or a regulatory gene controlling flavone biosynthesis. Pigments remained visible in pubescence after methanol extraction, suggesting that a major part of the pigments was polymerized.

Genetics of promiscuous nodulation in soybean: nodule dry weight and leaf color score

Article Abstract:

The segregation pattern of promiscuous nodulation is studied using two measures of N(sub 2) fixation effectiveness, nodule dry weight (NDW) and leaf color score (LCS) per plant. LCS represented total effectiveness of nodulation to provide nitrogen for the plant.
