The plant heat stress protein, Hsp101, and the yeast ortholog, Hsp104, are required to confer thermotolerance in plants and yeast (Saccharomyces cerevisiae), respectively. In addition to its function during stress, Hsp101 is developmentally regulated in plants although its function during development is not known. To determine how the expression of Hsp101 is regulated in cereals, we investigate...
Medicinal plante Borazambol with the scientific name of Perovskia abrotanoides Karel. belongs to the family Lamiaceae. It is growing wild in the margin of mountainous roads of arid and cold climate of north Iran. It is for a long time that indigenous people by different methods in traditional medicine use its products in preventing and curing diseases. In this research, essential oils of Perovs...
The response of plants to drought stress depends on several factors including the plant developmental stage and the length and severity of the stress applied. Common bean (Phaseolus vulgaris L.) is the most important pulse crop that is cultivated worldwide for human consumption. Understanding of the mechanisms responsible for its response to drought is, therefore, essential. An increasing numbe...
BACKGROUND In tightly closed human habitats such as space stations, locations near volcano vents and closed culture vessels, atmospheric CO(2) concentration may be 10 to 20 times greater than Earth's current ambient levels. It is known that super-elevated (SE) CO(2) (>1,200 µmol mol(-1)) induces physiological responses different from that of moderately elevated CO(2) (up to 1,200 µmol mol(-1)),...
Plants respond to environmental stresses by altering gene expression, and several genes have been found to mediate stress-induced expression, but many additional factors are yet to be identified. OsNAP is a member of the NAC transcription factor family; it is localized in the nucleus, and shows transcriptional activator activity in yeast. Analysis of the OsNAP transcript levels in rice showed t...
Transcribing Bacillus cereus DNA was visualized by means of autoradiography of electrophoretically separated EcoRI restriction endonuclease DNA fragments hybridizing 32P-labeled RNA. Hybridization of RNA of dormant spores, vegetative cells, and outgrowing spores indicates the following. (i) A large fraction of the nonribosomal RNA in dormant spores is transcribed at a limited number of regions ...
The effect of drought on the chickpea variety ILC 3279 was investigated at the vegetative stage. After 20 days from sowing, the plants subjected to drought stress for 3, 5 and 7 days imposed by withholding water were permitted to recover by rewatering for 2 days after 3, 5 and 7 days of drought. Shoot elongation, leaf production, fresh and dry biomass reduced while MDA and proline accumulation ...
