Regulation of hordein synthesis in barley high lysine mutant Notch-2.
Genomic DNA isolated from barley cv. NP 113 and its high lysine mutant Notch-2, and restricted with different restriction enzymes was hybridized with B1 and C-hordein DNA probes. Similar Southern hybridization patterns were observed between NP 113 and Notch-2. Dot blot hybridization analysis of RNA isolated at different developmental stages and from different tissues of seed showed temporal as well as tissue specific expression. The results obtained indicate that regulation at the level of transcription/post transcription may be responsible for lower accumulation of hordein in mutant Notch-2.
