Proteomics approaches have been a useful tool for determining the biological roles and functions of individual proteins and identifying the molecular mechanisms that govern seed germination, vigour and viability in response to ageing. In this work the dry seed proteome of four Arabidopsis thaliana genotypes, that carry introgression fragments at the position of seed longevity quantitative trait...

We show that seed-specific overexpression of the sunflower (Helianthus annuus) HaHSFA9 heat stress transcription factor (HSF) in tobacco (Nicotiana tabacum) enhances the accumulation of heat shock proteins (HSPs). Among these proteins were HSP101 and a subset of the small HSPs, including proteins that accumulate only during embryogenesis in the absence of thermal stress. Levels of late embryoge...

The tonoplast intrinsic proteins TIP3;1 and TIP3;2 are specifically expressed during seed maturation and localized to the seed protein storage vacuole membrane. However, the function and physiological roles of TIP3s are still largely unknown. The seed performance of TIP3 knockdown mutants was analysed using the controlled deterioration test. The tip3;1/tip3;2 double mutant was affected in seed ...

Water absorption is a prerequisite for seed germination. During imbibition, water influx causes the resumption of many physiological and metabolic processes in growing seed. In order to obtain more complete knowledge about the mechanism of seed germination, two-dimensional gel electrophoresis was applied to investigate the protein profile changes of rice seed during the first 48 h of imbibition...

A study was performed to study the effect of drought stress on protein changes of five wheat genotypes. Wheat genotypes were planted in early November, growing season of 2008-2009. The experiment was carried out in a factotial design with three replications. Two drought stress levels (irrigated and Non irrigated) and five genotype of wheat (F103-L-1-12//PONY/OPATA, F1.158/FDL//BLO/3/SH14414/CRO...

ABSTRACT Background Antibiotic resistance makes antimicrobial peptides (AMPs) agents an alternative for treatment of pathogenic diseases. They are isolated from various animals invertebrates, vertebrates and plants. The present study shows the electrophoretic pattern of protein and peptides from Vicia Faba seed and reports our first attempt to study the antibacterial activity of Vicia faba...
