| cytoplasm affects grain weight and filled-grain ratio in indica rice. | cytoplasmic effects on agronomic traits--involving cytoplasmic and nuclear genomes of either different species or different cultivars--are well documented in wheat but have seldom been demonstrated in rice (oryza sativa l.). to detect cytoplasmic effects, we introgressed the nuclear genomes of three indica cultivars--guichao 2, jiangchengkugu, and dianrui 449--into the cytoplasms of six indica cultivars - dijiaowujian, shenglixian, zhuzhan, nantehao, aizizhan, and peta. these 18 nuclear substitu ... | 2011 | 21631950 |
