We performed a genetic analysis of sRNA abundance in flag leaf from an immortalized F2 (IMF2) population in rice. We identified 53,613,739 unique sRNAs and 165,797 sRNA expression traits (s-traits). A total of 66,649 s-traits mapped 40,049 local-sQTLs and 30,809 distant-sQTLs. By defining 80,362 sRNA clusters, 22,263 sRNA cluster QTLs (scQTLs) were recovered for 20,249 of all the 50,139 sRNA cl...

In order to study effect of phosphorus fertilizer and micronutrients foliar application on yield sorghum, a field experiment was conducted in at 2011 in Research Farm of Payame Noor University of Zahedan, Iran. This experiment was done as split plot Based on randomized complete block design with three replications. Experiment treatments included: micronutrients foliar application containing ele...

Senescence is a highly regulated process which is under genetic control. In monocarpic plants, the onset of fruit development is the most important factor initiating the senescence process. During senescence, a large fraction of plant nutrients is reallocated away from vegetative tissues into generative tissues. Senescence may therefore be regarded as a highly effective salvage mechanism to sav...

general and specific combining ability of some rice lines and cultivars with irri sources were determined using the line × tester procedure (5 pure lines were crossed with 4 local cultivars as tester). parents and their progenies were planted in a randomized complete block design with three replications in the research field of iran rice research institute. traits such as yield and its componen...

Stagonospora nodorum blotch (SNB) caused by Stagonospora nodorum is a severe disease of wheat (Triticum aestivum) in many areas of the world. S. nodorum affects both seedling and adult plants causing necrosis of leaf and glume tissue, inhibiting photosynthetic capabilities, and reducing grain yield. The aims of this study were to evaluate disease response of 280 doubled haploid (DH) individuals...

The present study consists of 21 rice genotypes including one check variety that were evaluated in 2021 to genetic variability, correlation and path coefficient for thirteen quantitative characters. Observation recorded the variability parameters, yield its attributing traits. On basis mean performance MTU-1224 was found be superior grain per hill followed by, BPT-329, KNM-118 MTU-1001 give hig...

Different plant species have different levels and locations of silicon accumulation in their tissues, and may or may not have silica bodies. Grasses usually accumulate these bodies, which may have different shapes depending on the genotype. Besides, this element can be beneficial to crops. The present study aimed to examine the forms and locations of silicon accumulation, as well as silicon con...

Hybrid rice varieties have higher yield potential over inbred varieties. This improvement is not always translated to the grain yield and its physiological causes are still unclear. In order to clarify it, two field experiments were conducted including two popular indica hybrids (BRRI hybrid dhan2 and Heera2) and one elite inbred (BRRI dhan45) rice varieties. Leaf area index, chlorophyll status...

Immunoaffinity purification of polyribosomes (polysomes) from crude leaf extracts of Arabidopsis (Arabidopsis thaliana) was achieved with transgenic genotypes that overexpress a translational fusion of a ribosomal protein (RP) with a His(6)-FLAG dual epitope tag. In plants with a cauliflower mosaic virus 35S:HF-RPL18 transgene immunopurification with anti-FLAG agarose beads yielded 60-Svedberg ...

the experiment was performed to evaluate the morphological, phenological and yield aspects of two different echinochloa species, including barnyardgrass (e. crus-galli) and watergrass (e. orizoides) as a new-introduced weed species. the study was conducted as a 2-years pot-experiment under outdoor condition at rice research institute of iran (rrii) in rasht. the results demonstrated that; time ...
