Six lines and five testers were crossed in line x tester fashion and the F1s were evaluated under coastal saline situation. The ratio between the estimates of additive and dominance variances indicated preponderance of nonadditive gene action for the characters namely, plant height, number of productive tillers, boot leaf length, panicle length, grain weight per primary panicle and grain yield ...

Multivariate analyses were performed using 13 morphological traits and 13 molecular markers (10 SSRs and three ISSRs) to assess the phylogenetic relationship among tungro resistant genotypes. For morphological traits, the genotypes were grouped into six clusters, according to D(2) statistic and Canonical vector analysis. Plant height, days to flowering, days to maturity, panicle length, number ...

The functions of the three isoenzymes of cytosolic glutamine synthetase (GS1;1, GS1;2, and GS1;3) and two NADH-glutamate synthases (NADH-GOGAT1 and NADH-GOGAT2) in rice (Oryza sativa L.) were characterized using a reverse genetics approach and spatial expression of the corresponding genes. OsGS1;2 and OsNADH-GOGAT1 were mainly expressed in surface cells of rice roots in an NH4 (+)-dependent man...

The erect panicle model super-rice can rationally transform the solar energy into accumulated organic matter (biomass) and increase grain yield. The phenotype of erect panicle architecture controlled by DENSE AND ERECT PANICLE 1 (DEP1) has been used in rice breeding for nearly a century owing to its high-yield, lodging tolerance with strong stem, reasonable population structure and high nitroge...

Grasses produce tiller and panicle branching at vegetative and reproductive stages; the branching patterns largely define the diversity of grasses and constitute a major determinant for grain yield of many cereals. Here we show that a spatiotemporally coordinated gene network consisting of the MicroRNA 156 (miR156/)miR529/SQUAMOSA PROMOTER BINDING PROTEIN LIKE (SPL) and miR172/APETALA2 (AP2) pa...

Although flowering time is often associated with plant size, little is known about how flowering time genes affect plant architecture. We grew four rice lines having different flowering time genotypes (hd1 ehd1, hd1 Ehd1, Hd1 ehd1 and Hd1 Ehd1) under distinct photoperiod conditions. By using genotype-treatment combinations that resulted in similar flowering times, we were able to compare the ef...
