Three-week old plants of rice (Oryza sativa L. cv CT9993 and IR62266) developed gradual water stress over 23 days transpiration without watering, during which period the mid-day leaf potential declined to ∼–2.4 MPa, compared with ∼–1.0 MPa in well-watered controls. More than 1000 protein spots that were detected extracts by proteomic analysis showed reproducible abundance within replications. Of these proteins, 42 a significant change under stress, 27 them exhibiting different response...
Perennial grains hold promise, especially for marginal landscapes or with limited resources where annual versions struggle.
Abstract There is an urgent need for agricultural systems to intensify sustainably, increasing crop productivity, farmer livelihoods and soil health while using fewer resources. Crop perennialization, the conversion of especially annual grains perennial forms, has shown such possibility. Here we report successful breeding rice assess its performance potential. Domesticated, Asian ( Oryza sativa ) was hybridized with African relative longistaminata . From a single planting, irrigated produced...
Drought stress is the major constraint to rice ( Oryza sativa L.) production and yield stability in rainfed ecosystems. Identifying genomic regions contributing drought resistance will help develop cultivars suitable for through molecular marker assisted breeding. Quantitative trait loci (QTLs) linked plant water indicators, phenology traits under irrigated conditions were mapped by means of a doubled‐haploid (DH) population 154 lines from cross CT9993‐5‐10‐1‐M/IR62266‐42‐6‐2. The DH...
Removing carbon dioxide (CO2) from the atmosphere and storing (C) in resistant soil organic matter (SOM) is a global priority to restore fertility help mitigate climate change. Although it widely assumed that retaining rather than removing or burning crop residues will increase SOM levels, many studies have failed demonstrate this. We hypothesised microbial nature of provides predictable nutrient stoichiometry (C:nitrogen, C:phosphorus C:sulphur–C:N:P:S) target using supplementary nutrients...
Abstract The rice orthologue of maize domestication gene Teosinte branched 1 ( Tb1 ) affects tillering. But, unlike gene, it was not selected during domestication. Here, we report that an OsTb1 duplicate OsTb2 has been artificially upland adaptation and natural variation in is associated with tiller number. Interestingly, transgenic overexpressing this shows increased rather than decreased tillering, suggesting gains a regulatory effect opposite to following duplication. Functional analyses...
In the rainfed lowlands, rice ( Oryza sativa L.) develops roots under anaerobic soil conditions with ponded water, prior to exposure aerobic and water stress. Constitutive root system development in has been reported have a positive effect on subsequent expression of adaptive traits extraction during We examined effects phenotyping environment identification quantitative trait loci (QTLs) for constitutive morphology using 220 doubled‐haploid lines (DHLs) from cross ‘CT9993‐5‐10‐1‐M’ (CT9993;...
AbstractGenotypic variation in the root system is a potential source for improving drought tolerance of rainfed lowland rice (Oryza sativa L.). Our work aimed at characterizing both constitutive traits (those present under well -watered conditions) and adaptive developed response to rewatering) among eight diverse genotypes three sets greenhouse experiments (experiments 1, 2, 3). Under well–watered conditions, genotypic was observed shoot ratio, growth rate, specific length, deep mass per...
Transpiration efficiency, W, the ratio of plant carbon produced to water transpired and isotope discrimination leaf dry matter, Δd, were measured together on 30 lines C4 species, Sorghum bicolor, in glasshouse eight grown field. In glasshouse, mean W observed was 4.9 mmol C mol-1 H2O range 0.8 mol -1 H2O. The Δd 3.0 0.4‰. field, lower at 2.8 4.6‰. Significant positive correlations between for plants consistent with theory, opposite those C3 showed that variation an integrated measure...
Duration of the drought period is important for plant response during and after rewatering. We hypothesized that, if duration extended, (1) high seedling vigor rapid development a deep root system will not be advantageous, (2) osmotic adjustment more important. Six diverse rice (Oryza sativa L.) genotypes were selected from rainfed lowland germplasms to examine adjustment, their relationship with biomass production rewatering, under two different durations (shorter prolonged) in greenhouse....
