Profiling elemental contents in wheat grains and clarifying the underlying genetic systems are important for breeding of biofortified crops. Our objective was to evaluate potential 269 Afghan landraces increasing cultivars. The three major (Mg, K, P) minor (Mn, Fe, Zn) elements were measured by energy dispersive X-ray fluorescence spectrometry. Large variations observed among landraces. Marker-based heritability estimates low moderate, suggesting that complex quantitative traits. Genetic...

Gene expression after leaf rust infection was compared in near-isogenic wheat lines differing the Lr10 resistance gene. RNA from susceptible and resistant plants used for cDNA library construction. In total, 55 008 ESTs were sequenced two libraries, then combined assembled into 14 268 unigenes further analysis. Of these ESTs, 89% encoded proteins similar to (E value of ≤10−5) characterized or annotated NCBI non-redundant database representing diverse molecular functions, cellular...

The advancements in high-throughput sequencing technology have disclosed the substantial role of plant non-coding RNAs (ncRNAs), a relatively lessexplored but potent regulatory component, fine-tuning responsestoabiotic and biotic stresses. Among these ncRNAs, long (lncRNAs) microRNAs (miRNAs) are well-recognized robust elements that can modulate gene regulation at transcriptional, post-transcriptional, epigenetic levels. Emerging empirical evidence supports intricate orchestration...

Landraces are an important source of genetic diversity in common wheat, but archival collections Afghan wheat landraces remain poorly characterised. The recent development array based marker systems, particularly single nucleotide polymorphism (SNP) markers, provide excellent tool for examining the local populations. Here we used SNP analysis to demonstrate importance and found tremendous province-specific characteristics unique this geographic region.A total 446 were analysed using genotype...

Fusarium graminearum is responsible for head blight (FHB), which a destructive disease of wheat that makes its quality unsuitable end use. To understand the temporal molecular response against this pathogen, microarray gene expression analysis was carried out at two time points on three genotypes, spikes were infected by graminearum. The greatest number genes upregulated in Nobeokabouzu-komugi followed Sumai 3, whereas minimum Gamenya days after inoculation (dai). In Nobeokabouzu-komugi,...

Fusarium head blight (FHB), caused by graminearum, is a serious disease of wheat (Triticum aestivum L.) associated with contamination the mycotoxin deoxynivalenol (DON). The FHB-resistant cultivar 'Sumai 3' has been used extensively around world. existence variation in FHB resistance among accessions discussed. In this study, genetic collected from six countries were identified using SSR markers; our results demonstrate unique chromosome regions Sumai 3-AUT and 3-JPN ('Sumai Austria Japan,...

Cyanobacteria or blue green algae are prokaryotic photosynthetic microorganism that produces a wide array of substances, including plant growth regulators. In the case regulators, gibberellin, auxin, cytokinin, ethylene, abscisic acid and jasmonic have been detected in cyanobacteria. Many substances added to tissue culture media order promote regeneration.

The recent development in high‐throughput genotyping techniques requires new statistical methods to analyze large datasets. current available linkage mapping software are time consuming and limited terms of the maximum number markers that can be mapped on a single group. In this paper, we propose Perl pipeline, SimpleMap. This tool significantly improve speed currently with minimal impact marker order map length by limiting consideration duplicated tightly linked molecular during group...
