Food insecurity which has been aglobal threat, forces researchers todevelop crops with increased productivity even under varying climatic conditions. Rice, being asignificant staple and strategic crop, helps ensure economic stability, food, and nutritional security globally. Itmeets 20% ofthe calorie requirement ofpeople residing all over the world. Lately, rice cultivation and research have been facing hitherto unprecedented difficulties inthe context ofclimate-induced water scarcity and dwindling resources ofmanpower, arable land, etc. Inthis regard, direct seeded rice (DSR) asaresource conservation technique isgaining popularity asapotential...

Despite all the complications that arise with root research, such asslow, laborious, and unclear genetics, roots are apromising object ofinterest for breeders because many root traits are compatible with high yield potential. Itis agreat challenge for further research that there isawide demand for information onthe “hidden half ofplant metabolism” from many research fields. Wehave summarized the main obstacles inroot system research and sketched asolution for breeding infield conditions sothat the result was more meaningful tothe farmer. (i) The most important challenge inroot research islinking the functional identification...

Temperature isakey parameter that influences the uptake and subsequent utilization ofnitrogen byplants. Both suboptimal and supraoptimal temperatures can impair nutrient uptake. The close relatives ofbread wheat provide apossible source for breeders toincrease stress tolerance. The effect ofthe increasing temperature (5, 10, 15, 20 and 30C) onnitrate uptake and metabolism infive modern spring cultivars ofbread wheat (Triticum aestivum L.) and two cultivars ofemmer wheat (Triticum dicoccon Schrank), was monitored. Wheat plants were grown under controlled conditions inhydroponics. The parameters ofMichaelis-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 to83.33 in...

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. GOnegatively affected root growth and higher diameters of GO caused more adverse effects on the root. In total 3724GO-responsive genes were identified in root by transcriptome analysis. 70 differentially...
