Digital imaging combined with genome-wide association mapping links loci to plant-pathogen interaction traits (Plant Phys.)

Resistance to plant pathogens is often studied as a qualitative trait than quantitative, focusing on the lesion size and pathogen numbers. However, resistance to generalist plant pathogens, such as Botrytis cinerea, is known to involve multiple genes. Fordyce et al. used high-throughput phenotyping…

Rhizosphere microbiota structure alters to enable wilt resistance in tomato (Nature Biotech. - $)

Plants are frequently attacked by pathogens, but the pathogen-resistance is often attributed to the host. While interactions between the plant and its microbiota are recognized for their role in plant growth, their role in pathogen resistance is unknown. Kwak et al. studied the effect of soil-borne pathogen Ralstonia…

The genetic architecture of colonization resistance in Brachypodium distachyon to non-adapted stripe rust (Puccinia striiformis) isolates (PLOS Gen.)

The host range of a pathogen depends on its ability to overcome various plant defense barriers and successfully complete its life cycle. Although host “jumps” are considered rare, the pathogens are able to infect plants other than their usual host with varying degree of success. Yellow stripe rust…

The Arabidopsis negative regulator of root hydraulics XND1 is involved in abiotic and biotic stress responses  (Nature Comm.)

Proper uptake and management of water is essential for plant growth and adaptation to stress. However, there are gaps in the understanding of the genetics of root hydraulics, including the regulatory components. Tang et al. used a genome-wide associate analysis approach to identify XYLEM NAC DOMAIN 1 (XND1),…
