Biolistic Transformation of Japonica Rice Varieties

2020
Genetic improvement of rice is crucial to achieve global food security as rice is an important staple crop for more than half of the global population. One of the methodologies for genetic improvement is biolistic delivery of genetic components into plant cells.

Enigmatic double-stranded RNA in Japonica rice

Plant Molecular Biology, 1993
We have found a linear, 16 kb, double-stranded RNA (dsRNA) in symptomless Japonica rice (Oryza sativa L.) that is not found in Indica rice (Oryza sativa L.). The dsRNA was detected in every tissue and at every developmental stage, and its copy number was approximately constant (about 20 copies/cell). Double-stranded RNA was also detected in two strains

Mapping of qChalk1 controlling grain chalkiness in japonica rice

Molecular Biology Reports, 2023
Rice grain chalkiness is an undesirable characteristic that affects grain quality. The aim of this study was to map QTLs controlling grain chalkiness in japonica rice.In this study, two japonica rice cultivars with similar grain shapes but different grain chalkiness rates were crossed and the F2 and BC1F2 populations were subjected to QTL-seq analysis ...

Utilization of weedy rice for development of japonica hybrid rice (Oryza sativa L.)

Plant Science, 2011
Two representative weedy rice lines, three typical japonica varieties and three typical indica varieties were used for 6 pairs of reciprocal crosses. The morphological traits of twelve F(1) hybrid lines, their parents and four elite cultivars were investigated for heterosis over mid-parent (HM), over parent (HP) and competitive heterosis (CH) analysis.

Rice, Japonica (Oryza sativa L.)

2014
The importance of rice, as a food crop, is reflected in the extensive global research being conducted in an effort to improve and better understand this particular agronomic plant. In regard to biotechnology, this has led to the development of numerous genetic transformation protocols.

Anther Culture and Chromosome Doubling in Mediterranean Japonica Rice

2021
Anther culture is the most used technique to produce doubled haploid lines in rice. This technique is well developed in a wide range of indica rice genotypes. However, in japonica type, and more specifically, the Mediterranean japonica, the protocols are yet to be optimized.

Analysis of Vietnamese rice germplasm provides an insight into Japonica rice differentiation

Plant Breeding, 2003
AbstractGenetic differentiation among landraces of rice in northern Vietnam that lie in the centre of genetic diversity of Asian cultivated rice was analysed using DNA markers, and morphological and physiological traits to obtain an insight into the genetic differentiation of Asian rice.

Indica-japonica differentiation in Chinese rice landraces

Euphytica, 1993
Ninety Chinese rice landraces were examined with special reference to the indica-japonica differentiation in terms of traditional criteria, isozyme analysis and PCR analysis of the chloroplast DNA (cpDNA). Cultivars were separated into indica and japonica defined by a discriminant function (Z) based on key characters, as well as by isozyme genotypes ...

Analysis of Rice Blast Resistance Dominant Genes and their Combinations in Japonica Rice

Physiologia Plantarum
AbstractRice blast is a disastrous fungal disease affecting rice (Oryza sativa L.) and undermines world food security. Different ecological conditions and genetic backgrounds altered the effectiveness of rice blast resistance genes. Anhui (China) is a high‐incidence area and has long been affected by rice blast.

GERMPLASM EVALUATION FOR SALT TOLERANCE IN JAPONICA RICE

2020
Soil salinity is one of the environmental constraints that affect crop cultivation worldwide. Among cereals, rice (Oryza sativa L.) is one of the most salt-sensitive although cultivars can differ in their response to salt stress. In European coastal rice areas, the salt wedge intrusion phenomenon caused by the rise in the sea levels consequent to the ...
