High density molecular linkage map is a prerequisite to identify the quantitative traits loci. Construction of linkage maps, using mapping populations derived from two major subspecies: indica and japonica in rice, have been reported. However, limited work was conducted in indica subspecies. Present studies focused to construct a molecular map based on indica × indica (Shaheen Basmati × Pokkali...

This study focuses on the growth and morpho-physiological responses of Malaysian commercial variety MR219 rice to salinity stress during early vegetative stages, specifically germination five-leaf stage. For responses, seeds were grown for 10 days in different salt concentrations. Low significantly improves seed increases total number germinated seeds. However, higher (160 mM NaCl) inhibits red...

Salinity is a major threat to rice production worldwide. Several studies have been conducted to elucidate the molecular basis of salinity tolerance in rice. However, the genetic information such as quantitative trait loci (QTLs) and molecular markers, emanating from these studies, were rarely exploited for marker-assisted breeding. To better understand salinity tolerance and to validate previou...

The GATA gene family is one of the most conserved families of transcription factors, playing a significant role in different aspects of cellular processes, in organisms ranging from fungi to angiosperms. GATA transcription factors are DNA-binding proteins, having a class IV zinc-finger motif CX2CX17-20CX2C followed by a highly basic region and are known to bind a consensus sequence WGATAR. In p...

In semiarid regions, soil salinity, like drought, restricts crop productivity, causing food shortages among most inhabitants—the smallholder subsistence farmers. Seasonal wetlands formed in these regions during the rainy seasons could be utilised for rice (Oryza spp.) cultivation to increase security, but is sensitive salinity. Field and greenhouse-pot experiments were performed at University o...

Combining ability along with heterosis was elucidated in the 21 F1 hybrid population of rice derived from a 7 × diallel mating design. Furthermore, to formulate strategy for marker-based prediction heterosis, molecular genetic diversity (GD) then surveyed among seven parental lines RAPD markers. Analysis combining revealed significant GCA and SCA variances ratio between aforesaid parameter more...

A novel yellow colony-forming bacterium, strain P3B162T was isolated from the pokkali rice rhizosphere from Kerala, India, as part of a project study aimed at isolating plant growth beneficial rhizobacteria from saline tolerant pokkali rice and functionally evaluate their abilities to promote plant growth under saline conditions. The novel strain P3B162T possesses plant growth beneficial traits...
