Abstract This chapter discusses current progress and prospects of molecular breeding and strategies for developing better saline-tolerant sorghum (Sorghum bicolor) varieties. Most molecular breeding techniques for salt tolerance have been carried out in controlled environments where the plants were not exposed to any variation of the surrounding environment, producing reliable results. Due to the polygenic nature of salt tolerance, the identified quantitative trait loci (QTLs) could be false QTLs. Therefore, QTL validation is important in different plant populations and field conditions. Subsequently, marker validation is important before utilizing marker-assisted selection for screening salt-tolerant plants. Combining molecular breeding with conventional breeding can hasten the development of salt-tolerant sorghum varieties.

Abstract Out of the different objectives of wheat breeding, this chapter focuses on the direct increment of wheat yields via genetic improvement of the crop. The efficiency of modern molecular techniques, along with the availability of the whole-genome sequence of wheat, in mining wheat germplasm for allele-specific desirable traits is also discussed.

Abstract This chapter discusses the applications of CRISPR-mediated genome editing to improve the abiotic stress tolerance (such as drought, heat, waterlogging and cold tolerance) of maize. CRISPR/Cas9 has great potential for maize genome manipulation at desired sites. By using CRISPR/Cas9-mediated genome editing, numerous genes can be targeted to produce elite maize cultivars that minimize the challenges of abiotic stresses. In the future, more precise and accurate variants of the CRISPR/Cas9 toolbox are expected to be used for maize yield improvement.

Abstract Citrate transporters belonging to the multidrug and toxic compound extrusion (MATE) family of membrane transporters in sorghum and maize, SbMATE and ZmMATE1, respectively, play a major role in aluminium (Al) tolerance. However, these MATE members show regulatory differences, as well as peculiarities in their genetic effect and mode of action. These aspects, which are discussed in this chapter, have to be considered to design successful breeding programmes in order to achieve maximum Al tolerance and, consequently, to improve grain and biomass production in regions of the world with Al toxicity. As shown in this chapter, target genes with major effects and molecular tools are available for marker-assisted breeding for improving Al tolerance both in sorghum and maize. However, wide adaptation to acid soils should be sought by pyramiding genes controlling different traits such as drought tolerance, P acquisition, resistance to diseases and other stresses commonly found in each agroecological environment.

Abstract This paper discusses wheat responses to heat stress (including morphological and growth, cellular structure and physiological responses) and the molecular-genetic bases of heat response in wheat (including topics on mapping quantitative trait loci related to heat tolerance and the role of functional genes in response to heat stress). The improvement of heat tolerance of wheat by comprehensive strategies is also described. It is believed that with the emphasis on genetic resource exploration and with better understanding of the molecular basis, heat tolerance will be improved during wheat breeding programmes in the future.

Abstract Understanding the impact of excess moisture (EM) on maize plants at various growth stages, and studying the phenological, physiological and molecular responses of tolerant maize genotypes towards adaptation to EM stress, could help define ways in which this trait could be improved through targeted breeding. Thus, this chapter discusses the (i) impact of EM stress on maize plants, (ii) phenological adaptations and physiological mechanisms leading to EM stress tolerance in maize, and (iii) molecular signature of EM stress tolerance. Genetic studies on EM stress tolerance in maize are presented, and the application of molecular mreeding for EM tolerance in maize is described.
