Background: Direct seeding is an efficient cultivation technique in rice. However, poor low temperature germinability (LTG) of modern rice cultivars limits its application. Identifying the genes assoc...
Leaf rolling and discoloration are two chilling-injury symptoms that are widely used as indicators for the evaluation of cold tolerance at the seedling stage in rice. However, the difference in cold-r...
The market success of any rice cultivar is exceedingly dependent on its grain appearance, as well as its grain yield, which define its demand by consumers as well as growers. The present study was und...
We report here the suitable explant with high efficiency of transformation and the positive effects of timentin over other antibiotics like carbenicillin and cefotaxime on the elimination of Agrobacte...
Heritability is an important genetic parameter of the trait under selection. 193 F2:3 families of a cross between 'MousaTarom' and '304' were evaluated under field conditions. The studied traits were ...
Gene expression in tiller development by the semidwarfing gene sd-1 was studied under two different nitrogen levels. A Japonica tall variety Norin 29, its semidwarfing near isogenic line SC-TN 1, and ...
Two experiments were carried out to analyze the expression of some agronomic characteristics by semidwarfing gene sd-1, which has played an important role in improvement of rice productivity per area....
Rice garin shattering habit is closely associated with the abscission layer formed at the base of sterile lemmas (empty glumes). In the current study, the character expression of sh-2, one of the repr...
Brassinolide (BL), a brassinosteroid, applied to rice plants in pots promotes panicle ripening. In this study, we examined the effect of BL applied at the meiosis and flowering stages on endogenous le...
The thermo-sensitive genic male sterile (TGMS) T29s line was sterile when exposed to daily mean temperatures of 24.1°C or above during the critical stage (from 15 to 11 days before heading). It was co...
To elucidate the major physiological process to cause genotypic variation in the seedling vigor of rice, we analyzed the dry matter accumulation in the seedling for diverse cultivars distinguishing he...
Thirty-nine chromosome segment substitution lines (CSSLs) population derived from a Koshihikari/Kasalath cross was used for quantitative trait locus (QTL) analysis of plant type in rice (Oryza sativa ...
Cloning of a Cytochrome P450 Gene Induced by Ethylene Treatment in Deepwater Rice (Oryza sativa L.)
Changes in gene expression patterns by high nitrogen (High-N) and High-N plus cooling at the young microspore stage (High-N-cooling) in rice mature anthers were analyzed by semiquantitative RT-PCR wit...
A method to demonstrate varietal differences in seedling establishment of rice under low temperatures and methods of data analyses are discussed. Nursery boxes were filled with sieved soil up to 0, 4...
