Appropriate leaf shape has proved to be useful in improving photosynthesis and increasing grain yield. To understand the molecular mechanism of leaf morphogenesis, we identified a rice mutant nrl1, which was characterized by a phenotype of narrow and rolled leaves. Microscopic observation showed that the mutation significantly decreased the number of vascular bundles of leaf and stem. Genetic analysis...
Tiller number is highly regulated by controlling the formation of tiller bud and its subsequent outgrowth in response to endogenous and environmental signals. Here, we identified a rice mutant htd2 from one of the 15,000 transgenic rice lines, which is characterized by a high tillering and dwarf phenotype. Phenotypic analysis of the mutant showed that the mutation did not affect formation of tiller...
A thermo-sensitive chlorophyll deficient mutant was isolated from more than 15,000 transgenic rice lines. The mutant displayed normal phenotype at 23°C or lower temperature (permissive temperature). However, when grown at 26°C or higher (nonpermissive temperature) the plant exhibited an abnormal phenotype characterized by yellow green leaves. Genetic analysis revealed that a single nuclear-encoded...
