A Review on: Photo protective role of non-photosynthetic pigments and leaf pubescence against UV-B radiation in the traditional rice varieties

Origin of life was never being thought without considering the role of UV radiation. Once the “boon” is slowly becoming “curse” for life, similarly enhanced UV-B radiation have harmful effect on rice productivity. Rice (Oryza sativa L.) plants are exposed to many biotic and abiotic factors but the problem of enhanced UV-B radiation created by the anthropogenic activities resulted in Ozone layer depletion. Focusing on this, the main objective of study is to summarize the various response of traditional and wild rice varieties of western part of Odisha against the enhanced UV-B radiation. However no screening of traditional rice varieties for UV-B resistance hitherto. Traditional rice varieties have contains high amount of anthocyanin, flavonoides and pubescent hair which are act as quencher of UV-B radiation. Rice plants are performing well to cope up with such problems but depletion of stratospheric Ozone layer has created the threat of enhanced UV-B radiation which causes the reduction of productivity by reducing the rate of photosynthesis, plant growth and overall yield in most of the rice cultivars. So, the scope of further research should be focused on the selection of tolerant species for improving knowledge, scope of genetic improvement and other protective response of Rice varieties against UV-B radiation and provide insight for the breeders to develop stress resistance rice genotype in the near future.
