A probable pathway of ureide assimilation in pigeon pea pods

Abstract

Ureides (allantoin and allantoic acid) and the activities of glutamine synthetase, glutamate dehydrogenase, uricase. allantoinase and urease, the enzymes presumbly involved in the assimilation of ureides, were determined both in the vegetative organs and reproductive structures at 15-day interval starting from day 75 after sowing to complete maturity of the crop (day 120 after sowing). Based on the concentration of ureides and the distribution of the above enzymes in various plant parts, a probable pathway of ureide assimilation in pigeonpea pods has been proposed.
