Abstract:
Rice (Oryza sativa L.) is an important food crop species and most widely grown cereal. A key objective of rice breeding is the development of high-yielding, photosynthetically efficient rice varieties. In recent years, many outstanding genes have been used in rice breeding due to the constant development of molecular breeding technique, which is highly important for increasing rice yields. Increasing rice yield necessitates the discovery of novel genes and alleles from the rice gene pool, as well as genetic manipulation of novel traits. To increase the rice yield, it is required to find superior alleles influencing yield component traits. Using publically available sequence data from the IRRI 3K rice genome sequencing project, this work attempted to examine the allelic diversity of a chloroplast localized protein YL1 (LOC_Os02g05890) gene across a diverse set of 186 rice accessions. YL1 has 135 INDELs and 87 SNPs (Single Nucleotide Polymorphisms) according to allelic diversity analysis. In this study, four haplotypes (H1, H2, H3 and H4) contributed by six non synonymous SNPs were identified for YL1.
