Characteristics of biological control agents and their antagonism against rice pathogens and pests
Rice is an important staple food for over half of the world’s population. Rice production routinely faces the risk of pathogen and pest outbreaks which may cause significant yield loss such as rice root-knot nematodes, bacterial leaf blight, and brown planthopper. Currently, pesticide use is the …

Common Accommodation Mechanisms for Mutualistic and Detrimental Fungi in Oryza sativa (Rice) Roots
Rice roots engage in symbiosis with ancient symbiotic fungi such as R. irregularis, whilst resisting invasion of the detrimental fungus M. oryzae, a major causative agent of the rice blast (leaf) disease. M. oryzae can also invade rice roots with simple non-melanised hyphopodia formed on the rice …

Effect of soil amendments on the chemical transformation of arsenic and the microbial diversity in rice paddy microbiome
… arsenic biogeochemistry. For sustainable rice production, rice needs to be free from arsenic. Different soil amendments such as animal manure in flooded paddy soil could enhance arsenic reductive mobilization, biomethylation, and volatilization which could be a useful option for the …

Forest-based poverty alleviation in North-Eastern Vietnam
… seasonal increases mainly based on crop (maize, rice, root) and forest protection for Bac Kan, and seasonal increases for particular forest products (firewood, timber/poles) and crop (maize, rice) for Thai Nguyen. Poor people in both provinces have less diverse income sources. By using poverty …

Image-based deep learning approaches for plant phenotyping
… phenotyping tasks, including characterization of rice root anatomy based on microscopic root cross-section images, estimation of sorghum stomatal density and area based on microscopic images of leaf surfaces, and estimation of the chalkiness in rice exposed to high night temperature based on …

The role of the apoplastic transport barriers for radial water and ion uptake in rice (Oryza sativa L.) and corn (Zea mays L.) roots
For rice, the overall radial hydraulic conductivity (Lpr) was lower than those of other cereal roots. The stele/endodermis, aerenchyma, and the outer part of roots (OPR) arrange in series and their resistances to the overall radial water flow are additive. However, the hydraulic resistance of the …

Genetic Control of Root System Architecture in Rice
… century. Improvement of cultivation of rice, a primary source of calories for nearly half of the world’s people, provides a unique opportunity to address this challenge. As breeding in cereals has largely focused on aboveground phenotypes, root system traits represent potential …
