“…Gas exchange is a key mechanism in plant tissues for maintaining cellular functions and energy production. Stomatal regulation plays an important role in preventing transpiration and water loss through the stomata, with stomatal opening often resulting in up to 90% water loss [ 36 , 37 ]. When transpiration rates increase, stomatal closure reduces water loss in sorghum.…”

Drought stress is one of the most severe natural disasters in terms of its frequency, length, impact intensity, and associated losses, making it a significant threat to agricultural productivity. Sorghum (Sorghum bicolor), a C4 plant, shows a wide range of morphological, physiological, and biochemical adaptations in response to drought stress, paving the way for it to endure harsh environments. In arid environments, sorghum exhibits enhanced water uptake and reduced dissipation through its morphological activity, allowing it to withstand drought stress. Sorghum exhibits physiological and biochemical resistance to drought, primarily by adjusting its osmotic potential, scavenging reactive oxygen species, and changing the activities of its antioxidant enzymes. In addition, certain sorghum genes exhibit downregulation capabilities in response to drought stress. Therefore, in the current review, we explore drought tolerance in sorghum, encompassing its morphological characteristics and physiological mechanisms and the identification and selection of its functional genes. The use of modern biotechnological and molecular biological approaches to improving sorghum resistance is critical for selecting and breeding drought-tolerant sorghum varieties.

Plant breeders leverage mutagenesis using chemical, biological, and physical mutagens to create novel trait variations. Many widely used sorghum genotypes have a narrow genetic base, which hinders improvements using classical breeding. Enhancing the diversity of the sorghum genome thus remains a key priority for sorghum breeders. To accelerate the genetic enhancement of sorghum, an extensive library comprised of seeds from 150,000 individual mutant plants of the Sorghum bicolor inbred line BTx623 was established using ethyl methanesulphonate (EMS) as a mutagen. The sorghum mutant library was bulked into 1498 pools (~100 seed heads per pool). In each pool, DNA was extracted from a subset of the seed and screened using the FIND‐IT technology based on droplet digital PCR. All 43 nucleotide substitutions that were screened using FIND‐IT were identified, demonstrating the potential to identify any EMS‐derived mutation in an elite line of sorghum within days. This diverse library represents the largest collection of sorghum mutants ever conceived, estimated to cover 240% of all possible EMS‐induced mutation points within the Sorghum genome. Using FIND‐IT, the speed at which a specific desired EMS‐derived mutation can be identified is a major upgrade to conventional reverse genetic techniques. Additionally, the ease at which valuable variants can be integrated into elite commercial lines is a far simpler and less expensive process compared to genome editing. Genomic variations in the library will have direct utility as a breeding resource for commercial sorghum applications, allowing enhanced adaptation to climate change and enhanced yield potential in marginal environments.

The potential for sorghum to be the driver of economic development in Sub-Saharan economies, including South Africa, is enormous. However, there has been a notable decline in the production, use, and consumption of sorghum due to the changes in preferences and lifestyle of its consumers in Southern Africa. While existing and extant studies have studied the benefits and impacts of sorghum on the African economy, there is an inadequate understanding of the feasibility of sorghum farming in South Africa using Garrett’s ranking technique. As a result, this study explores the feasibility of sorghum farming in the Nyoni area of KwaZulu Natal, South Africa. Hence, a survey was conducted with a sample size of 150 respondents that were purposively selected. An interview schedule was also used to collect primary data, and the data were analyzed using Garrett’s ranking technique. The results of this study indicated that edaphic factors, climatic factors, volatile markets, information transfers, education, drought resistance variety, access to credit, and technological advancement were critical in making sorghum farming feasible in the Nyoni area of KwaZulu Natal. Therefore, this study recommends that there is an overarching need to explore the feasibility of sorghum farming, starting at a smaller scale until a more stable state of marketability and potential profitability has been established.
