Description Accepted date: June 22, 2016
Leaf is a source organ that serves dual function in photosynthesis and transpiration. As a primary
interface between plant and ecosystem, it performs a range of biological processes from carbon assimilation and
metabolite partitioning to plant productivity. Basic features of the leaf functionality are conserved in angiosperms
exhibiting common and unique characteristics. Spinach has been the model crop for studying leaf function,
primarily photosynthesis. It is a reservoir of several hundreds of primary and secondary biomolecules. To better
understand the molecular basis for photochemical reaction and metabolic partitioning, we developed leaf
proteome of Indian spinach (Beta vulgaris var. all green). LC-ESI-MS/MS analysis identified 639 proteins exhibiting
discrete molecular features and functions, including photosynthesis, transpiration, gaseous exchange, transport,
redox status, cell defense, and floral induction besides the presence of proteins with unknown function. This
represents the first comprehensive foliage proteome of green leafy vegetable. Together, this work provides
important insights into the molecular networks underlying spinach leaf biological processes.
