Sweet sorghum is a promising target for biofuel production. It is a C4 crop with low input requirements and accumulates high levels of sugars in its stalks. However, large-scale planting on marginal lands would require improved varieties with optimized biofuel-related traits and tolerance to biotic and abiotic stresses. Considering this, many studies have been carried out to generate genetic and genomic resources for sweet sorghum. In this review, we discuss various attributes of sweet sorghum that make it an ideal candidate for biofuel feedstock, and provide an overview of genetic diversity, tools, and resources available for engineering and/or marker-assisting breeding of sweet sorghum. Finally, the progress made so far, in identification of genes/quantitative trait loci (QTLs) important for agronomic traits and ongoing molecular breeding efforts to generate improved varieties, has been discussed.

1988 lncRNAs were identified in sweet sorghum roots under cadmium treatment; lncRNA 15962 and lncRNA 11558 were validated to be the key lncRNAs involved in regulating cadmium accumulation and translocation. Cadmium (Cd) has become one of the most harmful and widespread pollutants with industry development. Sweet sorghum is an ideal plant for phytoremediation of Cd-contaminated soil.

Unlabelled: Sorghum, the fifth largest global cereal crop, comprises various types, such as grain, sweet, forage, and biomass sorghum, delineated by their designated end uses. Among these, sweet sorghum ( (L.) Moench) stands out for its unique versatility, exceptional abiotic stress tolerance and large biomass serving the multi-purpose of high-sugar forage, syrup, and biofuel production.

Biomass crops engineered to accumulate energy-dense triacylglycerols (TAG or 'vegetable oils') in their vegetative tissues have emerged as potential feedstocks to meet the growing demand for renewable diesel and sustainable aviation fuel (SAF). Unlike oil palm and oilseed crops, the current commercial sources of TAG, vegetative tissues, such as leaves and stems, only transiently accumulate TAG. In this report, we used grain (Texas430 or TX430) and sugar-accumulating 'sweet' (Ramada) genotypes of sorghum, a high-yielding, environmentally resilient biomass crop, to accumulate TAG in leaves and stems.

Lignin nanoparticles (LNPs) exhibit application potential in fields such as ultraviolet (UV) shielding, antioxidant materials, and water purification owing to their versatile chemical structure. However effective, nontoxic solvent-based strategies to synthesize LNPs with diverse morphologies have not been reported. This study presents a continuous biorefinery method to produce monodisperse LNPs with diverse morphologies from isopropanol-solubilized lignin (IPA-lignin).
