Large scale germplasm screening for identification of novel rice blast resistance sources

Frontiers in Plant Science, 2014
Rice is a major cereal crop that contributes significantly to global food security. Biotic stresses, including the rice blast fungus, cause severe yield losses that significantly impair rice production worldwide. The rapid genetic evolution of the fungus

Natural rice rhizospheric microbes suppress rice blast infections [PDF]

BMC Plant Biology, 2014
The natural interactions between plant roots and their rhizospheric microbiome are vital to plant fitness, modulating both growth promotion and disease suppression. In rice (Oryza sativa), a globally important food crop, as much as 30% of yields are lost due to blast disease caused by fungal pathogen Magnaporthe oryzae. Capitalizing on the abilities of

Introgression of blast resistance genes (putative Pi-b and Pi-kh) into elite rice cultivar MR219 through Marker-Assisted Selection

Frontiers in Plant Science, 2015
Blast is the most common biotic stress leading to the reduction of rice yield in many rice-growing areas of the world, including Malaysia. Improvement of blast resistance of rice varieties cultivated in blast endemic areas is one of the most important ...

Multimodal Locomotion in Insect‐Inspired Microrobots: A Review of Strategies for Aerial, Surface, Aquatic, and Interfacial Motion

Advanced Robotics Research, EarlyView.
This review identifies key design considerations for insect‐inspired microrobots capable of multimodal locomotion. To draw inspiration, biological and robotic strategies for moving in air, on water surfaces, and underwater are examined, along with approaches for crossing the air–water interface.

Characterization of Rice Mutants with Enhanced Susceptibility to Rice Blast

Molecules and Cells, 2005
As a first step towards identifying genes involving in the signal transduction pathways mediating rice blast resistance, we isolated 3 mutants lines that showed enhanced susceptibility to rice blast KJ105 (91-033) from a T-DNA insertion library of the japonica rice cultivar, Hwayeong.

Defending rice crop from blast disease in the context of climate change for food security in Nepal

Frontiers in Plant Science
Blast, caused by Pyricularia oryzae (teleomorph Magnaporthe oryzae), is one of the most devastating diseases in rice, causing 10-30% yield losses and threatening Nepal’s food and nutritional security. The Himalayan foothills are hotspots for blast fungus
