The seed consists of several layers of specialized cell-types that divide and differentiate following a highly regulated programme in time and space. A cytological approach was undertaken in order to study the histo-differentiation at mid-embryogenesis in Medicago truncatula as a model legume, and in Pisum sativum using serial sections of embedded immature seed. Little published information is ...

Seed development and nitrogen (N) storage depend on delivery of amino acids to seed sinks. For efficient translocation to seeds, amino acids are loaded into the phloem in source leaves and along the long distance transport pathway through xylem-phloem transfer. We demonstrate that Arabidopsis thaliana AMINO ACID PERMEASE2 (AAP2) localizes to the phloem throughout the plant. AAP2 T-DNA insertion...

Fruit and seed development in plants is a complex biological process mainly involved in input and biosynthesis of many storage compounds such as proteins and oils. Although the basic biochemical pathways for production of the storage metabolites in plants are well characterized, their regulatory mechanisms are not fully understood. In this study, we functionally identified rapeseed (Brassica na...

A detailed knowledge of storage reserve accumulation in developing seeds can provide vital information to create strategies for improving the lipid content as well as the natural value of castor (Ricinus communis L.) crop. After hand pollination (female flowers-tagged), seed filling (lipid and protein accumulation) in castor bean is initiated as early as 7 days after pollination (DAP). Accumula...

The Eruca sativa (Taramira) germplasm, comprising 102 accessions was evaluated for total seed storage proteins via sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE). The accessions were collected from different ecological areas of Pakistan. Total seed storage proteins were electrophoretically separated on 12.5 to 15.0% polyacrylamide gels. A total of 17 protein bands were det...
