Increased lodging resistance in long-culm, low-lignin gh2 rice for improved feed and bioenergy production
Lignin modification has been a breeding target for the improvements of forage digestibility and energy yields in forage and bioenergy crops, but decreased lignin levels are often accompanied by reduced lodging resistance. The rice mutant gold hull and internode2 (gh2) has been identified to be lignin deficient. GH2 has been mapped to the short arm of chromosome 2 and encodes cinnamyl-alcohol de...
متن کاملCulm in rice straw as a new source for sugar recovery via enzymatic saccharification.
Rice straw was manually dissected and two main fractions were recovered: a culm and a leaf sheath/blade fraction, in order to evaluate their potential as feedstocks for the recovery of fermentable sugars. In the case of cv. Koshihikari and Milkyqueen, most soft carbohydrates (SCs: glucose, fructose, sucrose, starch, and beta-1,3-1,4-glucan) were present in the culms, reaching 47.9% and 89.2% of...
متن کاملGenetic interaction between 2 tillering genes, reduced culm number 1 (rcn1) and tillering dwarf gene d3, in rice.
Mutant genes, reduced culm number 1 (rcn1) and bunketsuwaito tillering dwarf (d3), affect tiller number in rice (Oryza sativa L.) in opposite directions. The d3 mutant was reported to increase tiller number and reduce plant stature. Our objective was to compare the phenotype of the d3rcn1 double mutant with each single mutant and parental rice cultivar "Shiokari" and to clarify whether the Rcn1...
متن کاملGibberellin deficiency pleiotropically induces culm bending in sorghum: an insight into sorghum semi-dwarf breeding
Regulation of symmetrical cell growth in the culm is important for proper culm development. So far, the involvement of gibberellin (GA) in this process has not yet been demonstrated in sorghum. Here, we show that GA deficiency resulting from any loss-of-function mutation in four genes (SbCPS1, SbKS1, SbKO1, SbKAO1) involved in the early steps of GA biosynthesis, not only results in severe dwarf...
متن کاملUtilization of Stiff Culm Trait of Rice smos1 Mutant for Increased Lodging Resistance
Although the introduction of semi-dwarf trait into rice has led to improved lodging resistance making it capable of supporting high grain yield, lodging still remains a concern when attempting to further increase the grain yield of rice. However, improving the lodging resistance in rice by depending on the semi-dwarf trait alone is possible only up to a certain limit, beyond which other traits ...
