“…A literature search resulted in more than 200 papers published since 1978 when the first bmr mutants were developed [84]. Furthermore, many reviews have focused on digestion efficiency, lignin composition and improved saccharification [21,26,86,87,138,139]. Here bmr2, bmr6 and bmr12 are presented.…”

Biomass rich in lignocellulose from grasses is a major source for biofuel production and animal feed. However, the presence of lignin in cell walls limits its efficient utilisation such as in its bioconversion to biofuel. Reduction of the lignin content or alteration of its structure in crop plants have been pursued, either by regulating genes encoding enzymes in the lignin biosynthetic pathway using biotechnological techniques or by breeding naturally-occurring low lignin mutant lines. The aim of this review is to provide a summary of these studies, focusing on lignin (monolignol) biosynthesis and composition in grasses and, where possible, the impact on recalcitrance to bioconversion. An overview of transgenic crops of the grass family with regulated gene expression in lignin biosynthesis is presented, including the effect on lignin content and changes in the ratio of p-hydroxyphenyl (H), guaiacyl (G) and syringyl (S) units. Furthermore, a survey is provided of low-lignin mutants in grasses, including cereals in particular, summarising their origin and phenotypic traits together with genetics and the molecular function of the various genes identified.

“…Genetically improved germplasm with high biomass yield and better compositional quality have the potential to improve sorghum of biomass conversion to ethanol (Torres et al., 2016). Thus, information on combining ability is needed to identify potentially superior parents and hybrids, as well as to assist in defining the pattern of genetic effects on quantitative trait expression in biomass sorghum (Goyal & Kumar, 1991; Silva et al., 2018). The effects of general combining ability (GCA) estimates provide information on the frequency of favorable alleles with additive effects present in the parental lines.…”

“…The cross‐breeding scheme is another very important factor in the improvement of autogamous plants. In addition, gene pyramidation is interesting in this process, to add as many genes as possible to one line, and also recommended when the number of parents to be crossed in an autogamous‐breeding program is high (Silva et al., 2018).…”

Biomass sorghum [Sorghum bicolor (L.) Moench] is considered as a raw material of great potential for bioenergy generation. The objective of this study was to estimate the combining ability of biomass sorghum of A and R lines, carrying the bmr-6 allele, evaluating different crop years and site effect, aiming at the bioenergetic potential for the production of second-generation ethanol. Four male-sterile lines (A), and 10 fertility restorative lines (R) were used, obtaining 40 hybrids bmr and sensitive to the photoperiod. From the F 1 seeds, four experiments were conducted in different crop years and sites. The data were submitted to individual diallel analysis according to IV model proposed by Griffing (1956), adapted for partial diallel design by Geraldi and Miranda Filho (1988). Promising lines were identified to breeding line groups A and R, aiming to obtain new lines breeding to obtain superior hybrids. The crop year and site effects were significant for most traits. The use of partial diallel analysis is promising for the biomass sorghum breeding program and A and R lines with potential bioenergetic were identified for the production of second-generation ethanol.

“…This sorghum type usually has stem higher than 5 m, more number of leaves, fibrous roots, greater potential for vegetative growth, and is suitable for mechanization [10]. Besides producing secondgeneration ethanol, biomass sorghum also releases energy during biomass combustion [11]. It is a good substitute to corn and sugarcane with additional benefit of less water consumption.…”

Biomass for Bioenergy - Recent Trends and Future Challenges

Plant-based renewable biofuels guarantee sustainable solutions to food and energy demands. High-biomass C4 grasses including sugarcane, corn, and sorghum are potential candidates for bioenergy. Among these, sorghum enjoys the status of a highly diverse food, feed, and biofuel source worldwide. The natural attributes like abiotic stress tolerance, diverse genetic base, viable seed industry, and sound breeding system make sorghum a perfect candidate for establishing an efficient and low-cost biofuel industry. Scientists are exploring ways to exploit forage, sweet, and biomass sorghums as climate-smart energy crops. In this context, conventional breeding has played a significant role in developing high-yielding sorghum varieties. For biomass sorghum, stem compositional analysis helps screen low lignin and high polysaccharide types as feedstocks for biofuels. Recent tools of phenomics, genomics, proteomics, and genome editing are key players of designing eco-friendly bioenergy sorghum. Here, we report stem compositional analysis and proteomicsbased evaluation of USDA sorghum germplasm as a baseline to develop sorghum as a biofuel feedstock.
