Expression profiling of yield related genes in rice cultivars under terminal drought stress.

Background: Rice crop may experience a significant reduction in yield-up to 50%-due to two occurrences during drought stress: unsuccessful peduncle elongation in panicle exertion and ineffective grain filling. The comprehension of mechanisms that promote drought tolerance during these growth phases is crucial for the production of rice that can withstand drought conditions, thus averting a decrease in crop yield.

Methods And Results: The expression of two xyloglucan endo transhydrolase/glucosylase genes (OsXTH 5 and 19) in peduncle tissue and a sucrose transporter gene (OsSUT1) in flag leaf sheath were assessed.

Superior adaptation of aerobic rice under drought stress in Iran and validation test of linked SSR markers to major QTLs by MLM analysis across two years.

Drought is one of the biggest challenges for rice (Oryza sativa L.) production in rainfed areas. Developing "aerobic rice" cultivars could be a valuable alternative to irrigated/rainfed areas.

Identification of CBF14 and NAC2 Genes in Aegilops tauschii Associated with Resistance to Freezing Stress.

Low temperature as one of the most important environmental factors limits the productivity of plants across the world. Aegilops, as a wild species of Poaceae, contains low temperature-responsive genes. In this study, we analyzed morphological (wilting, chlorosis, and recovery) and physiological (ion leakage) characteristics to identification of a cold-tolerant genotype.

Preparation of microparticles of naproxen with Eudragit RS and talc by spherical crystallization technique.

Microparticles of naproxen with Eudragit RS and talc were prepared by the spherical crystallization technique, i.e. quasi-emulsion solvent diffusion method.
