Symptom evolution in rice genotypes under iron toxicity conditions

Effects of Rhizobacteria on iron uptake and root iron plaque formation in lowland rice under conditions of iron toxicity

Selection and testing of reference genes for accurate RT-qPCR in rice seedlings under iron toxicity

Reverse Transcription quantitative PCR (RT-qPCR) is a technique for gene expression profiling with high sensibility and reproducibility. However, to obtain accurate results, it depends on data normalization by using endogenous reference genes whose expression is constitutive or invariable. Although the technique is widely used in plant stress analyzes, the stability of reference genes for iron ...

Genetic and biochemical analysis of high iron toxicity in yeast: iron toxicity is due to the accumulation of cytosolic iron and occurs under both aerobic and anaerobic conditions.

Iron storage in yeast requires the activity of the vacuolar iron transporter Ccc1. Yeast with an intact CCC1 are resistant to iron toxicity, but deletion of CCC1 renders yeast susceptible to iron toxicity. We used genetic and biochemical analysis to identify suppressors of high iron toxicity in Δccc1 cells to probe the mechanism of high iron toxicity. All genes identified as suppressors of high...

Evaluation of salinity tolerance in rice genotypes

Salinity is considered as one of important physical factors influencing rice (Oryza sativa L.) production. Knowledge of salinity effects on rice seedling growth and yieldcomponents would improve management practices in fields andincrease our understanding of salt tolerance mechanisms in rice. This study was designed to assess the role of Saltol QTL in regards to effects of salinity on plant gro...

Combining ability of rice genotypes under coastal saline soils

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 ...
