objective: ageing of the stored seed is a natural phenomenon and the seeds tend to lose viability even under ideal storage conditions. accelerated ageing has been recognized as a good predictor of the storability of seed lots. aged seeds show decreased vigor and produce weak seedlings that are unable to survive once reintroduced into a habitat. the characteristics of the chemical composition of...

during the recent decades, substantial changes are made in the borders and contents of physiology as a basic course for the students in medicine. here some strategies are presented to preserve the classical and integrative approaches in teaching physiology, while these approaches extent our knowledge to molecular, sub-cellular and cellular levels.

Borage is an important medicinal plant which must be cultivated commercially in order to meet the ever-increasing demand for pharmaceutical industry. This study was done under hydroponics condition. Seeds of Borage were obtained from Neka Research Center (North of Iran). After applying Benomyl fungicide, the seeds were rinsed with distilled water and planted in vermiculite. After germination an...

Small heat shock proteins (sHSPs) are a diverse group of proteins and are highly abundant in plant species. Although majority of these sHSPs were shown to express specifically in seed, their potential function in seed physiology remains to be fully explored. Our proteomic analysis revealed that OsHSP18.2, a class II cytosolic HSP is an aging responsive protein as its abundance significantly inc...
