Phosphate Starvation Inducible Metabolism in Lycopersicon esculentum: II. Characterization of the Phosphate Starvation Inducible-Excreted Acid Phosphatase.
Three-day-old suspension cultured cells of Lycopersicon esculentum transferred to a Pi-depleted medium had 2.7 times the excreted acid phosphatase (Apase) activity of cells transferred to a Pi-sufficient medium. Cell growth during this time period was identical for the two treatments. Excreted Apase activity was resolved into two fractions on a Sephadex G-150 column. Most of the phosphate starv...
متن کاملPhosphate Starvation Inducible Metabolism in Lycopersicon esculentum: III. Changes in Protein Secretion under Nutrient Stress.
Phosphate starvation increased the secretion of at least six proteins by suspension cultured tomato (Lycopersicon esculentum L. and L. pennellii) cells. Cells exhibited a biphasic response to phosphate (Pi) starvation. The early phase involved enhanced secretion of three proteins in response to transfer to a Pi-depleted media, while biomass accumulation continued at the same rate as in the Pi-s...
متن کاملPhosphate Starvation Inducible Metabolism in Lycopersicon esculentum: I. Excretion of Acid Phosphatase by Tomato Plants and Suspension-Cultured Cells.
Both tomato (Lycopersicon esculentum cv VF 36) plants and suspension cultured cells show phosphate starvation inducible (psi) excretion of acid phosphatase (Apase). Apase excretion in vitro was proportional to the level of exogenous orthophosphate (Pi). Intracellular Apase activity remained the same in both Pi-starved and sufficient cells, while Apase excreted by the starved cells increased by ...
متن کاملLeucine aminopeptidase: an inducible component of the defense response in Lycopersicon esculentum (tomato).
A leucine aminopeptidase (EC 3.4.11.1) cDNA clone (DR57) that was induced in response to Pseudomonas syringae pv. tomato (P.s. tomato) infection was isolated using a subtractive hybridization-enriched cDNA probe. Genomic DNA blot analysis showed that the tomato genome had two leucine aminopeptidase genes. The levels of DR57 mRNAs after P.s. tomato infection and mechanical wounding were determin...
متن کاملProteomic analysis of tomato (Lycopersicon esculentum) pollen.
In flowering plants, pollen grains are produced in the anther and released to the external environment with the primary function of delivering sperm cells to the female gametophyte. This study was conducted to identify proteins in tomato pollen and to analyse their roles in relation to pollen function. Tomato is an important crop which is grown worldwide and is an excellent experimental system....
