The issue of MeHg-contaminated rice, and the current understanding of the Hg cycling in the rice paddy ecosystem are presented, including the mechanism and processes of Hg species accumulation in rice plants and Hg methylation/demethylation processes in rice paddies and the primary controlling factors are presented.

It was concluded that three main problems in the current breeding of rice blast resistance are availability of few R (resistance) genes that confer resistance to both seedling and panicle blast, the resistance effect of pyramided lines is not the result of a simple accumulation of resistance spectrum, and only a few R genes have been successfully used for molecular breeding.

Experimental results analysis demonstrates that the proposed Rice-Fusion multimodal data fusion framework outperforms the outcome of unimodal frameworks in rice disease diagnosis.

Abstract Pot experiments were carried out to study the effects of rice straw (RS) and rice straw ash (RSA) on the growth of early rice and α-diversity of bacterial community in soils around rare earth mining areas of Xunwu and Xinfeng counties in South Jiangxi of China. The results showed that the exploitation of rare earth resources leads to soil pollution around rare earth mining areas and affects the growth of rice, and the content of rare earth elements (REEs) in rice was positively correlated with that in soils and negative correlated with dry weight of rice; The addition of RS to soils a...

Results indicates that the Yangtze River basin, especially Hunan, required more attention due to the elevated Cd concentrations in soil-rice ecosystems, and will provide a scientific reference for Cd pollution control and management with respect to paddy field ecosystems in China and other countries.

Torrefaction is an effective pretreatment process of biomass to enhance energy density and reduce moisture and oxygen contents. The kinetics analysis is important to estimate the torrefaction efficiency and understand the thermal degradation characteristics of torrefied biomass. In this study, the pyrolysis kinetics (Flynn–Wall–Ozawa method, Kissinger–Akahira–Sunose​ method, and Starink's method) of rice husk (RH), rice straw (RS), and their torrefied solid products were investigated under different heating rates. The results demonstrated that the increase of torrefaction temperature decreased...

This study conducted an extensive literature review on rice husk ash (RHA), with a focus on its particle properties and their effects on the fresh, mechanical, and durability properties of concrete when used as a partial cement replacement. The pozzolanic property of RHA is determined by its amorphous silica content, specific surface area, and particle fineness, which can be improved by using controlled combustion and grinding for use in concrete. RHA particle microstructures are typically irregular in shape, with porous structures on the surface, non-uniform in dispersion, and discrete throug...

Globally, protecting the environment is one of the major concerns and there is a need for an hour to accomplish the same by dropping numerous harmful activities such as less dependence on fossil fuels and tailpipe emissions. Additionally, a huge investment made on waste disposal is particularly not economical; but recycling is from the viewpoint of producing energy from renewable resources. These further result in the development of society in an eco-friendly way. Exploiting biodegradable wastes like agricultural or forestry residues, a non-edible portion is value-added biological products (bi...

A genome-scale gene expression resource covering the inflorescence-to-floret transition during early reproductive development is constructed, and it is demonstrated that a WOX transcription factor, DWARF TILLER1 (DWT1), regulates flower meristem activity.

Recent advances in studies on molecular interactions between rice and R. solani are summarized and multiple effective strategies have been developed to generate rice cultivars with enhanced sheath blight resistance.

Rice is food consumed regularly and is vital for the food security of over half the world’s population. Rice production on a global scale is predicted to rise by 58 to 567 million tonnes (Mt) by 2030. Rice contains a significant number of calories and a wide variety of essential vitamins, minerals, and other nutritional values. Its nutrients are superior to those found in maize, wheat, and potatoes. It is also recognised as a great source of vitamin E and B5 as well as carbohydrates, thiamine, calcium, folate, and iron. Phytic acid and phenols are among the phenolic compounds found in rice, al...

A framework that maps the activities defined in rice smart farming, data used in data modelling and machine learning algorithms used for each activity defined in the production and post-production phases of paddy rice is presented.

This graph-based super pan-genome of rice consisting of a 251-accession panel comprising both cultivated and wild species of Asian and African rice reveals extensive structural variations (SVs) and gene presence/absence variations and facilitates pinpointing of lineage-specific haplotypes for trait-associated genes.

Rice is generally sensitive to chilling stress, which seriously affects growth and yield. Since early in the last century, considerable efforts have been made to understand the physiological and molecular mechanisms underlying the response to chilling stress and improve rice chilling tolerance. Here, we review the research trends and advances in this field. The phenotypic and biochemical changes caused by cold stress and the physiological explanations are briefly summarized. Using published data from the past 20 years, we reviewed the past progress and important techniques in the identificatio...

Abstract Rice production and research have met unprecedented challenges in recent years. Yield and total production have plateaued for many years in some major producing rice‐producing countries while the demand from populations in poverty is ever increasing. For example, more than 100 million additional people became extremely poor, mostly from Asia and sub‐Saharan Africa in 2020 alone. Rice is not only the calorie source for half of the global population but also the key staple food for the world's poorest and undernourished people living in Asia and Africa. In this review, we have analysed ...

The resulting suite of plant prime editors enable point mutations, insertions and deletions in rice and wheat protoplasts through codon, promoter, and editing-condition optimization.

Instant (pre-cooked) rice contained fourfold higher levels of plastics, suggesting that industrial processing potentially increases contamination, and washing the rice with water significantly reduced plastic contamination.

Salinity is one of the major abiotic stresses which impose constraints to plant growth and production. Rice (Oryza sativa L.) is one of the most important staple food crops and a model monocot plant. Its production is expanding into regions that are affected by soil salinity, requiring cultivars more tolerant to saline conditions. Understanding the molecular mechanisms of such tolerance could lay a foundation for varietal improvement of salt tolerance in rice. In spite of extensive studies exploring the mechanism of salt tolerance, there has been limited progress in breeding for increased sali...

Irrigated rice-growing communities in sub-Saharan Africa are exposed to greater malaria risk, as well as more mosquitoes, and there is an urgent need to improve methods for growing rice without producing mosquitoes.

The identification and characterization of the produced mycotoxins and their biosynthetic pathways in U. virens highlights the pathogen a unique tool to unveil novel mechanisms for the interactions beteen nonobligate biotrophic pathogens and their hosts.
