Heat Stressor

Goat is popularly known as ‘poor man’s cow’, rears mostly by the rural people due to better adaptive capability to harsh environment. Heat stress either hot or cold; negatively influence the goat productive and reproductive performance. Both survivability and reproductive performance of goat most often depend on its ability to cope with heat stressor. Goats can rears in a wide range of environment and geography may it be hilly terrain or undulating topography due to cope with the heat stress via combination of behavioral, morphological, physiological, biochemical, metabolic, hormonal and molecular changes at the gene level. All these adaptive mechanisms and genes are important for the assessment of heat stress, adaptability and strategies for management, production of heat-tolerant transgenic goat using advance biotechnological tools for sustainable goat production in challenged environment due to climate change.

The present study observed the effect of heat stress on ovarian development, fecundity, and vitellogenin gene expression in silkworm,Bombyx mori. The result showed that the heat shock treatment to spinning larvae and pupae at 39°C (1 h and 2 h) did not cause any adverse effect on the reproductive performance ofB. mori.However, the heat shock treatment at 42°C or above caused a decrease in the fecundity. The heat shock treatment to day 2 pupae for 2 h at 45°C caused a drastic effect on the development of ovary as measured by gonadosomatic index. The study thus showed that a brief exposure ofBombyxlarvae and pupae to a temperature of 42°C or higher, much prevalent in tropical countries like India, greatly affects the ovarian development and reproductive performance of this commercially important insect. The study further showed a developmental- and tissue-specific expression of vitellogenin mRNA in fat body and ovary upon heat shock. When heat shock treatment was done at 39°C and 42°C to spinning larvae, ovary showed an upregulation in the expression of vitellogenin mRNA, whereas fat body failed to do so. However, at 45°C, both fat body and ovary showed a downregulation. The heat shock treatment to day 2 pupae showed an upregulation in the vitellogenin mRNA expression in both fat body and ovary, even at 45°C. The upregulation in the expression of vitellogenin upon heat shock indicates its role in thermal protection ofBombyxlarvae and pupae.
