Nitrogen assimilation enzyme gene transcripts from pod formation through to seed filling. (A) Gene transcript abundance patterns for NADH- and Fd-glutamate synthase (GOGAT). In early pods and seeds, Fd-GOGAT transcripts (Glyma03g28410 and Glyma19g31120) are more abundant, while later in seed development NADH-GOGAT (Glyma14g32500 and Glyma19g16450) transcripts are more highly expressed. (B) Allantoin metabolism gene transcript abundance (Supplementary Data File S5) is highest during early pod set and seed formation (Glyma13g31430, allantoinase). RPKM, reads per kilobase per million.
