The basic premise of high yield in rice is to improve leaf photosynthetic efficiency and coordinate the source-sink relationship in rice plants. Quantitative trait loci (QTLs) related to morphological traits and chlorophyll content of rice leaves were detected at the stages of heading to maturity, and a major QTL (qLSCHL4) related to flag leaf shape and chlorophyll content was detected at both ...

Previous studies with 95 bread wheat doubled haploid lines (DHLs) from the cross Chinese Spring (CS)xSQ1 trialled over 24 yearxtreatmentxlocations identified major yield quantitative trait loci (QTLs) in homoeologous locations on 7AL and 7BL, expressed mainly under stressed and non-stressed conditions, respectively. SQ1 and CS contributed alleles increasing yield on 7AL and 7BL, respectively. T...

abstract this research was conducted in toroq experimental field station, mashhad, iran, for two successive cropping seasons (2000-2002), using split plot experimental design based on complete randomized blocks with three replications. moisture stress treatments (at seven levels) were assigned to main plots, including: d1 ( full irrigation), d2 (no irrigation from one-leaf to double ridge) stag...

Segregating F4 families from the cross between drought sensitive (Yecora Rojo) and drought tolerant (Pavon 76) genotypes were made to identify SSR markers linked to leaf chlorophyll content, flag leaf senescence and cell membrane stability traits in wheat (Triticum aestivum L.) under water-stressed condition and to map quantitative trait locus (QTL) for the three physiological traits. The paren...

to identify the high yielding lines with optimal characteristics, 40 recombinant inbred lines derived from a cross between ‘norstar’ (winter wheat) and ‘zagros’ (spring wheat) cultivars were examined using a randomized complete block design with three replications in 2014 at the research station of faculty of agriculture, university of tabriz, iran. the measured characters consisted of peduncle...

Appropriate leaf rolling enhances erect-leaf habits and photosynthetic efficiency, which consequently improves grain yield. Here, we reported the novel lateral organ boundaries domain (LBD) gene OsLBD3-7, which is involved in the regulation of leaf rolling. OsLBD3-7 works as a transcription activator and its protein is located on the plasma membrane and in the nucleus. Overexpression of OsLBD3-...

The aim of this experiment was that study the effect of drought stress and different chemical and organic fertilizers systems on wheat flag leaf chlorophyll. This experiment was conducted as split plot based on completely randomized block design (CRBD) with four replications during 2009-2010 at experimental fields of Ramin university. Irrigation treatments were achived in I1(irrigation droped ...

The transcriptomes of senescing flag leaves collected from barley field plots with standard or high nitrogen supply were compared to identify genes specifically associated with nitrogen remobilization during leaf senescence under agronomically relevant conditions. In flag leaves collected in field plots with high nitrogen supply, the decline in chlorophyll content was delayed. By comparing chan...

The fortification of cereal grains with metal micronutrients is a major target to combat human malnutrition of Fe and Zn. Based on recent studies showing that N fertilization can promote Fe and Zn accumulation in cereal grains, we investigated here the influence of nitrate- or ammonium-based N fertilization on the accumulation of Fe, Zn, and Cu as well as metal chelator pools in flag leaves and...
