Seed-borne rice endophytes are capable of disseminating into host plant tissues as well as to their rhizosphere. Here, we investigated the occurrence of siderophore-producing bacteria (SPB) in the seed endospheres of two distinct rice (Oryza sativa L.) cultivars, TK8 (ssp. japonica) and TCN1 (ssp. indica), and their dissemination into the rhizospheres through culture-dependent methods.

Salinity has a significant impact on rice production in coastal, arid and semi-arid areas in many countries, including countries growing temperate rice, such as Kazakhstan. Salinity tolerant temperate japonica rice accessions were identified in this study, these accessions are important resources for breeding programs. SNPs located in the promising QTLs and candidate genes could be used for future gene validation and marker assisted selection.

Hill rices (Oryza sativa L.) are direct seeded rices grown on hill slopes of different gradients. These landraces have evolved under rainfed and harsh environmental conditions and may possess genes governing adaptation traits such as tolerance to cold and moisture stress.

125 rice samples of 10 rice varieties (Daithom8, IR50404, Jasmine85, DS1, OM4900, OM5451, OM6976, OM7347, ML202, Glutinous rice) collected from 10 provinces in the Mekong Delta were not different in grain length ranging from medium to long and were mainly tapered in shape. Except for DS1, because of the Japonica variety, it is round in shape.

Due to the diversity of rice varieties and cropping systems in China, the limitation of seeding density and seedling quality makes it hard to improve machine-transplanted efficiency. Previous studies have shown that indica and japonica varieties varied in machine transplanting efficiency and optimal seeding density.

Heilongjiang Province is a high-quality japonica rice cultivation area in China. One in ten bowls of Chinese rice is produced here. Increasing yield is one of the main aims of rice production in this area. However, yield is a complex quantitative trait composed of many factors.

Balancing the yield, quality and resistance to disease is a daunting challenge in crop breeding due to the negative relationship among these traits. Large-scale genomic landscape analysis of germplasm resources is considered to be an efficient approach to dissect the genetic basis of the complex traits.

Regarding the content of total polyphenols, the maximum average value obtained was 477 g Eq g-1 for rice from both countries and the best results for antioxidant activity, using the Photoquem® method with methanolic extract, was 3.43 µM Eq Trolox g-1 for the Italian rice samples. These results indicate that the technological processes influence the nutritional and functional quality of rice grain from these countries.

Genetic improvement of root system architecture is a promising approach for improved uptake of water and mineral nutrients distributed unevenly in the soil. To identify genomic regions associated with the length of different root types in rice, we quantified root system architecture in a set of 26 chromosome segment substitution lines derived from a cross between lowland indica rice, IR64, and upland tropical japonica rice, Kinandang Patong, (IK-CSSLs), using 2D & 3D root phenotyping platforms.

Rice plants are sensitive to the agro-climate conditions, being photoperiod one of main factor contributing to their adaptation to the region where they are grown. Dissecting the genetic bases underlying diversity in rice populations adapted to specific environmental conditions is a fundamental resource for breeding. In this study we have analysed a collection of japonica varieties adapted to temperate regions to perform association studies with traits of high agronomical interest such as heading date, plant height, number of panicles, panicle length and number of grains per panicle.

The brown plant hopper (BPH), Nilaparvata lugens, is one of the major pest of rice (Oryza sativa). Plant defenses against insect herbivores have been extensively studied, but our understanding of insect responses to host plants’ resistance mechanisms is still limited.

Lanthanum (La) is a rare earth element that can infuence plant growth and development. However, the efect of La on growth, yield formation and 2-acetyl-1-pyrroline (2-AP, a key compound responsible for the aroma of rice) biosynthesis in aromatic rice (Oryza sativa L. subsp. japonica Kato) has not been reported.

Since environmental issues have become a priority for everyone on the planet, and the fact that growing demand for fossil fuels will soon lead to a reduction in world reserves, except for climate change due to their use and greenhouse gas emissions. The aim of this work was to assess the potential for the introduction of biofuels and find the optimal conditions for the enzymatic hydrolysis of Japonica Rice husk. In addition, evaluate the positive and negative consequences because of the use and implementation of this technology.

Rice recombinant inbred lines (RILs) of Japonica x Indica cross were grown in irrigated conditions for identification of quantitative trait loci (QTLs) for yield associated traits. One hundred twenty one RIL lines were evaluated in the field environment. A total of one hundred twenty two SSR markers were used for polymorphism out of forty markers that showed parental polymorphism. Forty SSR markers were used to construct the genetic linkage map. In total, nine QTLs were identified for yield attributing traits.

Improvement of indica rice lines is a challenging task through application of anther culture as they are recalcitrant to culture distinctive to japonica rices. Current investigation aimed to verify the effect of cold pretreatment and phytohormones on the anther culture response of 6 crosses. Cold pretreatment for 7-10 days at 100C was found to have profound effect on callus induction frequency irrespective of the media employed and the prolonged treatment over the optimum showed to be inhibitory...
