A factorial completely randomized block design experiment with three replications was carried out in greenhouse to evaluate cereal genotypic variation in phosphorus (P) acquisition and utilization efficiency in a calcareous soil with low available P (4.6 mg P kg-1 soil) and high total P (1260 mg P kg-1 soil). Treatments consisted of eight bread wheat (Triticum aestivum L.), three durum wheat (T...

Aluminum (Al)-tolerance of different cultivars shows considerable differences. Elevation of rhizosphere pH is an external Al-resistant mechanism of plants. To elucidate the correlation between Al tolerance and the capacity of plants to modify the rhizosphere pH at different Al-tolerant levels, a comparative study on the wheat (Triticum aestivum L.) cultivars ET8 (Al-tolerant) and ES8 (Al-sensit...

Wheat is a cereal grain and one of the world's major food crops. Recent advances in wheat genome sequencing are by now facilitating its genomic and proteomic analyses. However, little is known about possible differences in total protein levels of hexaploid versus tetraploid wheat cultivars, and also knowledge of phosphorylated wheat proteins is still limited. Here, we performed a detailed analy...

Heat-responsive miRNAs regulate the expression of the transcription factors (HSFs) and majority of the heat stress-associated genes (HSPs). Here we report identification of few heats responsive miRNAs in wheat (Triticum aestivum L.)through de novo sequencing on Illumina Hiseq 2000. Validation of identified miRNAs in endospermic tissues of thermotolerant (HD2985) and thermosusceptible (NIAW-34-3...

The Russian wheat aphid (RWA), Diuraphis noxia (Kurdjumov), is one of the main pests small-grain cereal crops, including bread wheat, Triticum aestivum (Poaceae). In a series glasshouse experiments, we evaluated systemic effect endophytic Beauveria bassiana strain PPRI 7598 on D. biotype RWASA1 using three South African cultivars, Gariep, Molopo, and Kariega. objectives study were: (a) to deter...

ADP-glucose pyrophosphorylase (AGPase), the key enzyme in starch synthesis, consists of two small subunits and two large subunits with cytosolic and plastidial isoforms. In our previous study, a cDNA sequence encoding the plastidial small subunit (TaAGPS1b) of AGPase in grains of bread wheat (Triticum aestivum L.) was isolated and the protein subunit encoded by this gene was characterized as a ...

Winter cultivars of rye (Secale cereale L., cv Musketeer) and wheat (Triticum aestivum L. cvs Kharkov and Monopol), but not a spring cultivar of wheat (Glenlea), grown at cold-hardening temperatures showed, at high irradiances, a higher proportion of oxidized to reduced primary, stable quinone receptor (QA) than did the same cultivars grown under nonhardening conditions. In addition, there was ...

The photosynthetic responses to moderately high temperatures (38 degrees C, imposed at 21% or 2% O(2) in air and 1500 mumol m(-2) s(-1)) were compared in wheat (Triticum aestivum L.) cultivars grown in northern regions of Ukraine and expected to be relatively sensitive to high temperatures ('North' cultivars) and in cultivars grown in southern regions and expected to be relatively heat-tolerant...

Background: Global climate change facilitates the spread of diseases winter bread wheat ( Triticum aestivum L.) and increases yield losses caused by a combination these drought. Prevention depends on identification resistance genes introduction into commercial cultivars. Objective: The objective study was to evaluate widespread diseases, drought other agricultural traits amongst members diversi...

Resistance gene analog-expressed sequence tag (RGA-EST)-based markers have been used for variety discrimination and studies of genetic diversity in wheat. Our aim is to increase the competitiveness of public wheat breeding programs through intensive use of modern selection technologies, mainly marker-assisted selection. The genetic diversity of 77 wheat nucleotide binding site (NBS)-containing ...
