Abstract:
In Oryza sativa, indica and japonica are pivotal subpopulations, and other subpopulations such as aus and aromatic are considered to be derived from indica or japonica. In this regard, Oryza sativa accessions are frequently viewed from the indica/japonica perspective. This study introduces a computational method for indica/japonica classification by applying phenotypic variables to the logistic regression model (LRM). The population used in this study included 413 Oryza sativa accessions, of which 280 accessions were indica or japonica. Out of 24 phenotypic variables, a set of seven phenotypic

Abstract:
Oryza sativa ssp. javanica rice varieties exhibit a wide variation in the phenotypes of several important agronomic traits, including grain quality, grain shape, plant architecture, disease resistance, and high adaption to an unfavorable environment, indicating a great potential for rice improvement. DNA molecular markers are basic and critical tools in genetic analysis and gene mining. However, only a few whole-genome variation analyses have been performed in Oryza sativa ssp. Javanica (tropical japonica rice), and this has hampered the utilization of such an important resource. In this study

To investigate genetic diversity within and differentiation between the indica and japonica subspecies, 22 accessions of indica and 35 of japonica rice were examined by five microsatellite loci from each chromosome totalling 60 loci. Mean gene diversity value in the indica rice (H=0·678) was 1·18 times larger than in the japonica rice (H=0·574).

Mesocotyl elongation in rice is essential for seedling emergence. Our previous screening identified weedy rice accessions (Oryza sativa f. spontanea L.) (WR04-6) with unusual long mesocotyl. In this study, using rice cultivar Akihikari (Oryza sativa, subspecies japonica) as control, we observed that weedy rice accessions display more extensive microtubules (MTs) depolymerization in the early stage of mesocotyl elongation. At the end of mesocotyl elongation, the predominant MTs in weedy rice are transversely oriented, while, Akihikari has oblique MTs arrays.
