Root patterning: SHORT ROOT on the move [PDF]

open access: yesCurrent Biology, 2001
The radial pattern of the plant root is determined by the action of two transcription factors, SHORT ROOT and SCARECROW, which are produced in different cell types. The SHORT ROOT protein has now been shown to move from cell to cell, regulating transcription of the downstream SCARECROW gene in the target cells.

Agricultural intensification reduces microbial network complexity and the abundance of keystone taxa in roots

open access: yesThe ISME Journal, 2018
Root-associated microbes play a key role in plant performance and productivity, making them important players in agroecosystems. So far, very few studies have assessed the impact of different farming systems on the root microbiota and it is still unclear

Redefining fine roots improves understanding of below-ground contributions to terrestrial biosphere processes.

open access: yesNew Phytologist, 2015
Fine roots acquire essential soil resources and mediate biogeochemical cycling in terrestrial ecosystems. Estimates of carbon and nutrient allocation to build and maintain these structures remain uncertain because of the challenges of consistently ...

Resistance screening of white yam (Dioscorea rotundata Poir.) accessions against Meloidogyne incognita (Kofoid & White, 1919) Chitwood, 1949 using yam vines

open access: yesActa Agriculturae Slovenica, 2022
Root-knot nematode (Meloidogyne incognita) is an economically important phytoparasitic nematode species. In yam production, therefore, breeding for nematode resistance is an important environmentally friendly tool to manage root-knot nematodes damage ...
