Identification of differentially expressed genes in sorghum (Sorghum bicolor) brown midrib mutants.
Sorghum, a species able to produce a high yield of biomass and tolerate both drought and poor soil fertility, is considered to be a potential bioenergy crop candidate. The reduced lignin content characteristic of brown midrib (bmr) mutants improves the efficiency of bioethanol conversion from biomass. Suppression subtractive hybridization combined with cDNA microarray profiling was performed to...
متن کاملAlteration in Lignin Biosynthesis Restricts Growth of <i>Fusarium</i> spp. in Brown Midrib Sorghum
Funnell-Harris, D. L., Pedersen, J. F., and Sattler, S. E. 2010. Alteration in lignin biosynthesis restricts growth of Fusarium spp. in brown midrib sorghum. Phytopathology 100:671-681. To improve sorghum for bioenergy and forage uses, brown midrib (bmr)6 and -12 near-isogenic genotypes were developed in different sorghum backgrounds. The bmr6 and bmr12 grain had significantly reduced colonizat...
متن کاملCharacterization of novel Brown midrib 6 mutations affecting lignin biosynthesis in sorghum.
The presence of lignin reduces the quality of lignocellulosic biomass for forage materials and feedstock for biofuels. In C4 grasses, the brown midrib phenotype has been linked to mutations to genes in the monolignol biosynthesis pathway. For example, the Bmr6 gene in sorghum (Sorghum bicolor) has been previously shown to encode cinnamyl alcohol dehydrogenase (CAD), which catalyzes the final st...
متن کاملAlteration in lignin biosynthesis restricts growth of Fusarium spp. in brown midrib sorghum.
To improve sorghum for bioenergy and forage uses, brown midrib (bmr)6 and -12 near-isogenic genotypes were developed in different sorghum backgrounds. The bmr6 and bmr12 grain had significantly reduced colonization by members of the Gibberella fujikuroi species complex compared with the wild type, as detected on two semiselective media. Fusarium spp. were identified using sequence analysis of a...
متن کاملCell growth and product formation kinetics of biohydrogen production using mixed consortia by batch process
The cell growth and product formation kinetics of anaerobic biohydrogen production by mixed anaerobic cultures was investigated using unstructured models in the present study. They described the realtionship between biomass growth and product formation in the hydrogen production process. Experimental results show that the Logistic model and LeudekingPiret model could be adopted to describe the ...
