“…2). SbLEA3;1 and SbLEA3;2 were expressed at early stage of seed development and elevated significantly at maturity, while SbLEA3;3 and SbLEA3;4 expressed only in mature seeds (Dalal et al 2013). Expression pattern of stress associated protein (SAP) family gene (SbSAP14) was identified in root at 0, 2, 4, 8, and 12 h under high salt stress (250 mM) (Wang et al 2013).…”

“…These findings suggested that these 2 genes could potentially be used in improving salt stress tolerance in sorghum. Four late abundant embryogenesis 3 (LEA3) family genes (SbLEA3;1, SbLEA3;2, SbLEA3;3 and SbLEA3;4) were identified from the genome sequences of sorghum and their expression pattern was analyzed in seeds (at early and maturity stage) and leaf of sorghum under high salt stress (150 mM NaCl) (Dalal et al 2013). Among the 4 LEA3 family genes, 2 genes (SbLEA3;1 and SbLEA3;3) were highly expressed in leaf under salt stress (Fig.…”

Main conclusion Identification of molecular markers and characterization of nutrient transporters could help to improve the tolerance under abiotic and low nutrient stresses in sorghum ensuring higher yield to conserve food securityAbstract Sorghum is an important cereal crop delivering food and energy security in the semi-arid tropics of the world. Adverse climatic conditions induced by global warming and low input agriculture system in developing countries demand for the improvement of sorghum to tolerate various abiotic stresses. In this review, we discuss the application of marker-assisted breeding and nutrient transporter characterization studies targeted towards improving the tolerance of sorghum under drought, salinity, cold, low phosphate and nitrogen stresses. Family members of some nutrient transporters such as nitrate transporter (NRT), phosphate transporter (PHT) and sulphate transporter (SULTR) were identified and characterized for improving the low nutrient stress tolerance in sorghum. Several quantitative trait loci (QTL) were identified for drought, salinity and cold stresses with an intention to enhance the tolerance of sorghum under these stresses. A very few QTL and nutrient transporters have been identified and validated under low nitrogen and phosphorus stresses compared to those under drought, salinity and cold stresses. Marker-assisted breeding and nutrient transporter characterization have not yet been attempted in sorghum under other macro-and micro-nutrient stresses. We hope this review will raise awareness among plant breeders, scientists and biotechnologists about the importance of sorghum and need to conduct the studies on marker-assisted breeding and nutrient transporter under low nutrient stresses to improve the sorghum production.

“…These findings suggest that these two genes could potentially be used in improving stress tolerance of sweet sorghum. Dalal et al (2013) identified four genes encoding LEA3 proteins in the sorghum genome and further classified them into LEA3A and LEA3B subgroups based on the conservation of LEA3 specific motifs. The changes in the expression levels of the SbLEA3 genes in response to abiotic stresses, such as soil moisture deficit and osmotic, salt and temperature stress suggest that the LEA3 genes have non-redundant functions in stress tolerance in sorghum.…”

Sorghum is an important source of food, feed and brewing raw material, and is expected to be a promising bioenergy crop. Sorghum is well known for its strong resistance to abiotic stress and wide adaptability, and salt tolerance is one of its main characteristics. Increasing sorghum planting acreage on saline-alkalien land is one way to effectively use this kind of marginal soil. In this paper, domestic and overseas research on plant tolerance to soil salinity and alkalinity in sorghum, including salt-tolerant genetics and breeding, physiology, cultivation, and identification of tolerant germplasms, are reviewed. Suggestions for further studies on salinity and alkalinity tolerance in sorghum are given, and the prospects for sorghum production in saline-alkalien land are discussed.

“…[6] Subsequently, Dalal et al reported that the salt tolerance of sorghum is determined by genes and mainly inherited along the male line. [7] The content of osmotic regulators, such as proline, which is regulated by protein-encoding genes, would be increased to enhance sorghum resistance to stress factors. [8] Due to its high yield, rapid liquefaction, low viscosity during liquefaction and high fermentation speed, sorghum was used as a high biotransformation efficiency material to produce industrial ethanol and biofuel instead of corn.…”

KT and Nuo sorghum are planted in saline‐alkali (SA) soil (KT‐S, Nuo11‐S) and nonsaline‐alkali (NSA) soil (KT‐S, Nuo11‐NS) to demonstrate the impact of SA stress on the structure and properties of sorghum starch. SA decreases the amylose content (27.57%–20.43%) but increases the B2 + B3 chain content of branched amylopectin (18.86%–19.57%) in KT, in contrast to Nuo. The X‐ray diffraction (XRD) and small‐angle X‐ray scattering (SAXS) results confirms the crystallinity of sorghum starch, and the degree of ordering in semicrystalline lamellae is arranged as follows: Nuo11‐S > Nuo11‐NS > KT‐S > KT‐NS. Differential scanning calorimetry (DSC) confirms that SA improves thermal stability of starch granules. The noodles made of sorghum starch exhibit significant hydrolysis resistance compared to common noodles, and a higher hydrolysis rate is shown in SA‐starch noodles. Overall, it is essential to understand the fine structure and physicochemical properties of starch isolated from sorghum planted in different soils to help determine its appropriate applications.
