background: the effect of heat stress on physiologicalparameters has been well documented. however, there arereports of a genetic based heat tolerance in some sheep breeds.objectives: the aim of the present study was to monitor thephysiological responses of an iranian fat-tailed breed againstheat stress and an acute stress insult. methods:atotal numberof 15 fall-born ram lambs were selected and...

The response to drought stress is a complicated process involving stress sensing, intracellular signaltransduction, and the execution of a cellular response. Transcription factors play important roles in the signaling pathways including abiotic stress. In the present study a rice NF-YA transcription factor gene was partially characterized following dehydration. Disrupting the gene via a T...
