Abstract:
Salinity stress in paddy field had retarded the annual rice productivity influenced by ionic
imbalance, physiological damage and biochemical breakdown. Few reports had
categorized rice as a salt sensitive crop manifested in slow vegetative growth rate and
delayed reproductive stage. In parallel towards high rice market demands, the
establishment of new rice variety with high tolerance towards salt is important to
overcome the tragic rice agriculture lost due to soil problems. The opening of newly
paddy arable land is impossible due to urbanization. Instead of an exploitation of plant
genetic sources in conventional crop breeding, advances in molecular breeding should be
priority due wider genetic materials. Omega-3-Fatty Acid Desaturase (ω3-FAD) gene
from marine microalgae Chorella Vulgaris strain UMT-M1 was employed in this study as
a desired insert as the gene clustered as a saline-combat regulator. An initiative in this
new variety production require the optimization of powerful tissue culture protocol.
