MABBI – Research conducted by Bagus Herwibawa and Florentina Kusmiyati from Physiology and Plant Breeding Laboratory, Faculty of Animal Husbandry and Agriculture, Diponegoro University entitled Kontribusi Genomika dalam Penemuan Gen Toleran Salinitas pada Tanaman Padi.
Adverse environmental conditions, such as salinity, are major challenges limiting the productivity of rice. Salinity tolerance is highly complex and involves many genes. Therefore, it is difficult to conclude universally how rice responds to salinity. We aimed to explain the contribution of genomics to gene discovery of salinity tolerance in rice. Currently, genomics has contributed to the discovery of salinity tolerance related genes in rice, by comparative genomic and genome-wide association studies. The development of a genome database is also useful for identifying gene families related to salinity tolerance between species, based on homology and synteny. The obtained genes related to salinity tolerance can be used in marker-assisted backcrossing, marker-assisted selection, and genomic selection, however, the genes are not optimally used. The use of new tools, such as genetic engineering and genome editing areprovided newer and faster avenues to generate salt-tolerant rice. However, both tools also are not much used the obtained salinity tolerant genes. The research trends in online databases are predicted to continue to increase because it is cheap, relatively easy, and capable to produce predictive data. The databases, of course, must be able to be used by all researchers and plant breeders in Indonesia. (Tri/MABBI)
