The major part of the world’s food supply relies heavily on cereal crop cultivation. Today’s cereal production faces an existential challenge to ensure food security for all. This problem is complex but at least partially compounded by the environmental limitations to agricultural production. Cereal crops are continually exposed to resource deficits and a plethora of abiotic and biotic stresses, which compromise grain yield and quality.
The two resources with the greatest influence on cereal crop productivity are water and nitrogen (N). Insufficiency of water adversely affects many biochemical processes and physiological functions within plants. Water shortage restricts nutrient availability in plants, and during drought episodes, crops may suffer from both water and N deficiency. In this regard, we need more meticulous knowledge about the sophisticated interplay between water and N transportation. As an essential macronutrient, N amply contributes to the accumulation of biomass by affecting photosynthesis and the synthesis of proteins and nucleic acids. Besides promoting growth, N availability has a direct influence on plant responses to stress. Contemporary scientific approaches render new possibilities for insight into the interaction between N limitation/excess and alterations in the expression of specific genes, and in transcriptomic, metabolomic, and phenomic patterns in cereal plants responding to different abiotic and biotic stressors.
The current challenge of increasing resource-use efficiency (NUE and WUE) in cereal crops, and improving plant-stress tolerance and grain production, requires profound understanding of the genetic variation and genetic architecture of the so-called subtraits making up NUE, WUE, and stress tolerance. The genetic diversity within germplasm collections is a key foundation upon which agriculture and food security are based. We are lucky to have a vast part of this diversity preserved in ex situ seed genebanks. “Exotic” germplasm collections, in particular, composed of landraces, old varieties, and wild relatives, represent a rich pool of useful traits and genes, which can be incorporated into a crop’s genome.
We invite contributions to this Special Issue from scientists who do research in the field of plant physiology, biochemistry, molecular biology, molecular genetics, pathology and entomology, plant–soil interactions, and molecular breeding in cereals. Articles are welcome that address the intricate relationships between water and N transport, NUE and WUE, NUE and tolerance to nutrient deficiency, N and carbon metabolism, N and abiotic stress tolerance, the triggered signaling cascades, breeding for resource-use efficiency or for stress tolerance, the potential and utilization of genetic resources for improving nutrient-use efficiency and stress tolerance in cereals. Interdisciplinary works are particularly welcome. We believe that it is now possible to develop integral research on the whole plant, cellular, and subcellular level to gain new knowledge to support designing novel genotypes for modern on-target agriculture.

Abstract: Strigolactones (SLs) are biosynthetically carotenoid-derived terpenoid lactones. The natural SLs were grouped into two types, namely, strigol-type and orobanchol-type, and so far, there are 20 SLs have been identified from different plant kingdom or species. The more stable SLs called GR24 derived synthetically utilized for the investigation of SLs responses. SLs are one of the crucial endogenous plant hormones that possess a multifactorial role in plant and rhizosphere interactions, controlling mycorrhization and lateral shoot branching. SLs participated in the organization of plant architecture by reducing bud outgrowth in addition to various morphological and developmental processes collectively with other plant growth hormones namely auxins, cytokinins, gibberellins, and abscisic acid (ABA). SLs are regulating root growth and root organization structure through inhibiting lateral root production along with enhancing the root-hair elongation. The targeted genetic engineering of SLs leads to up- or down-regulation of crucial associated SLs genes and, in turn, potential alterations in rooting and vegetative systems and assist in generating plants more appropriate to different situations such as drought, salt stress, cold, water deficit, various biotic and abiotic stresses. This short review presents a clear outline of the structure, types, biosynthesis, signaling mechanisms of SLs. In addition to this, their potential function in plant growth and development and response to stress conditions was also provided shortly.
