Food insecurity which has been a global threat, forces researchers to develop crops with increased productivity even under varying climatic conditions. Rice, being a significant staple and strategic crop, helps ensure economic stability, food, and nutritional security globally. It meets 20% of the calorie requirement of people residing all over the world. Lately, rice cultivation and research have been facing hitherto unprecedented difficulties in the context of climate-induced water scarcity and dwindling resources of manpower, arable land, etc. In this regard, direct seeded rice (DSR) as a resource conservation technique is gaining popularity as a potential...

Quo vadis, breeding for an efficient root system, in the era of climate change?Review

Despite all the complications that arise with root research, such as slow, laborious, and unclear genetics, roots are a promising object of interest for breeders because many root traits are compatible with high yield potential. It is a great challenge for further research that there is a wide demand for information on the “hidden half of plant metabolism” from many research fields. We have summarized the main obstacles in root system research and sketched a solution for breeding in field conditions so that the result was more meaningful to the farmer. (i) The most important challenge in root research is linking the functional identification...

Temperature dependence of nitrate uptake kinetics in Triticum aestivum L. and Triticum dicoccon Schrank cultivarsOriginal Paper

Temperature is a key parameter that influences the uptake and subsequent utilization of nitrogen by plants. Both suboptimal and supraoptimal temperatures can impair nutrient uptake. The close relatives of bread wheat provide a possible source for breeders to increase stress tolerance. The effect of the increasing temperature (5, 10, 15, 20 and 30 °C) on nitrate uptake and metabolism in five modern spring cultivars of bread wheat (Triticum aestivum L.) and two cultivars of emmer wheat (Triticum dicoccon Schrank), was monitored. Wheat plants were grown under controlled conditions in hydroponics. The parameters of Michaelis-Menten kinetics,...

Yellow rust (YR), caused by Puccinia striiformis f.sp. tritici (Pst), is a global threat to wheat production. In this study the response of 46 wheat and triticale cultivars to Pst at the adult plant stage (APS) was evaluated during two successive growing seasons at Sulaimania, Iraq. Also, we used a molecular analysis to find the yellow rust resistance (Yr) genes present in the individual cultivars. The results revealed large differences in the response to Pst between the cultivars. Most of the cultivars were susceptible to YR; the mean coefficients of infection (CI) varied from 0.23 in cv. Sarah to 83.33 in...

Transcriptome analyses reveal the toxicity of graphene oxide with different diameters on buckwheat root growthOriginal Paper

Graphene-based materials (GBMs) have become potential soil pollutants due to their wide applications in agricultural environments. Although physiological mechanisms of plant responses to GBMs have been previously explored, the underlying molecular mechanisms remain unclear. In this paper, we analysed the physiological and transcriptomic changes of buckwheat (Fagopyrum spp.) roots exposed to 100 mg/L graphene oxide (GO) with different diameter. GO negatively affected root growth and higher diameters of GO caused more adverse effects on the root. In total 3 724 GO-responsive genes were identified in root by transcriptome analysis. 70 differentially...
