1.1.1.195 | G575A/G192D | the nucleotide substitution G575A occurs in BdCAD1 of the Bd4179 line, and consequently induces the G192D change in the highly conserved glycine-rich NADPH binding site GLGGVG | Brachypodium distachyon |
1.1.1.195 | additional information | screening of a chemically induced population of Brachypodium mutants (Bd21-3 background) for red culm coloration and identification of two mutants, Bd4179 and Bd7591, with mutations in the BdCAD1 gene. The amount of sinapic acid ester-linked to cell walls is measured for in the lignin-related CAD grass mutants. Functional complementation of the Bd4179 mutant with the wild-type BdCAD1 allele restores the wild-type phenotype and lignification. The Bdcad1 alleles are responsible for the reddish-brown phenotype | Brachypodium distachyon |

1.1.1.195 | malfunction | in CAD1 mutants Bd4179 and Bd7591, the mature stems displaye reduced CAD activity and lower lignin content. Their lignins are enriched in 8-O-4- and 4-O-5-coupled sinapaldehyde units, as well as resistant inter-unit bonds and free phenolic groups. By contrast, there is no increase in coniferaldehyde end groups. Saccharification assays reveal that Bd4179 and Bd7591 lines are more susceptible to enzymatic hydrolysis than wild-type plants. The Bdcad1 alleles are responsible for the reddish-brown phenotype, overview. Wild-type BdCAD1 rescues the altered lignin profile of Arabidopsis and Brachypodium CAD mutants. Saccharification yields are improved in Bdcad1 mutant lines but biomass yield is not compromised | Brachypodium distachyon |
1.1.1.195 | physiological function | involvement of BdCAD1 in lignification. Wild-type BdCAD1 rescues the altered lignin profile of Arabidopsis and Brachypodium CAD mutants | Brachypodium distachyon |
