Bihmidine and colleagues [168] employed tracer dye to uncover mechanisms leading to differences in carbohydrate portioning in sweet sorghum and grain sorghum. Sweet sorghum can be grown in many regions of the United States. Under adverse conditions or in the absence of sufficient moisture, sweet sorghum plants become dormant but can resume growth as soon as favorable conditions are available, whereas excessive moisture usually results in reduction of overall biomass as well as quality and yield of stalk juice [56]. Anami and colleagues [163] have recently reviewed the key biotic and abiotic stresses that impact sorghum crop. Sustainable alternative fuel feedstock opportunities, challenges and roadmaps for six US regions. 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. Plant Signal Behav. 1099. ; 2016. 2015;15(186):1–22. “Sweet Sorghum in some ways is similar to corn,” says Don Slack, Ph.D., professor in the Department of Biosystems Engineering.. “But it’s a much more drought tolerant, heat tolerant plant.” Through the research in Slack’s lab, he and his graduate students are finding better ways to grow the plants and optimize their production … Recently, a comprehensive survey of all the resources encompassing mutant populations, QTL dissection, identification, and isolation of genes controlling important agronomic traits, that are necessary for advancing molecular breeding and deeper understanding of the system, has been reported [69, 70]. 2016;9(1):40.

Therefore, screening and selection of appropriate varieties for each region is critical for optimum results. PLoS ONE. British Petroleum. Plant Cell Tiss Organ Cult. Rono and colleagues studied the effect of interaction between genotype and its environment on juice and ethanol production [166], whereas Ghate and coworkers analyzed near isogenic lines of sweet sorghum genotype S35 (having stay green loci) and showed that remobilization of sugars occur from stem to grains during drought stress [167]. The consensus map consisted of 1997 markers mapped to 2029 unique loci spanning 1603.5 cM. As reported for several other crops, genotype also directly affects the morphology and frequency of embryogenic calli [140]. Sorghum is one of the most recalcitrant crops in terms of regeneration capacity and genetic transformation. Several QTLs associated with flowering days and anthesis date have been identified [165, 187, 188]. Introduction. Sweet sorghum-dynamics of sugar yield in relation to phenological stages. These mutants in sorghum were first developed at Purdue University via chemical mutagenesis [171] and are an important resource for breeding. Since then, several sorghum varieties have been transformed through Agrobacterium-mediated transformation procedures and transformation efficiency has also improved [145, 153].
