Purification and characterization of a novel trypsin inhibitor from Solanum tuberosum subsp. andigenum var. overa: Study of the expression levels and preliminary evaluation of its antimicrobial activity.

Protease inhibitors (PIs) have been traditionally recognized by their potential biomedical application in events with exacerbation of endogenous proteases activity. Plant PIs have gained interest as naturally occurring molecules, which usually show lower environmental impact residual toxicity than synthetic compounds. In this work, we isolated, cloned, expressed and purified a novel trypsin inhibitor from S.

Effects of different Fe supplies on mineral partitioning and remobilization during the reproductive development of rice (Oryza sativa L.).

Background: Minimal information exists on whole-plant dynamics of mineral flow through rice plants and on the source tissues responsible for mineral export to developing seeds. Understanding these phenomena in a model plant could help in the development of nutritionally enhanced crop cultivars. A whole-plant accumulation study, using harvests during reproductive development under different Fe supplies, was conducted to characterize mineral accumulation in roots, non-flag leaves, flag leaves, stems/sheaths, and panicles of Kitaake rice plants.
