摘要
A single dominant gene Gc controls the trait of high chlorophyll. (Chl) content in rice (cultivar (cv.) Zhenshan 9713). The contents of Chl b and total. Chl. increased 100% and 25%, respectively, when Gc was introduced. In addition, photosynthetic rate, biomass and grain yield also increased by 20%, 17% and 16%, respectively. Three simple sequence repeats (SSR) markers (rm462, rm6340 and rm6464) that are linked to Gc were identified by amplification of DNA samples from near-isogenic lines using two hundred pairs of primers. The genetic distances on the short arm of rice chromosome 1 between Gc and rm6464, rm6340 and rm462 were 0, 0.588 and 1.18cM, respectively. (C) 2007 Elsevier GmbH. All rights reserved.
