S., Barry, L., Moukouanga, D., Barnard, S., Bhosale, R., Pridmore, T., Gantet, P., Vadez, V., Cubry, P., Kane, N., Bennett, M., Atkinson, J. A., Laplaze, L., Wells, D. M., & Grondin, A. (2024). Root metaxylem area influences drought tolerance and transpiration in pearl millet in a soil texture dependent manner

Pearl millet is a key cereal for food security in drylands but its yield is strongly impacted by drought. We investigated how root anatomical traits contribute to mitigating the effects of vegetative drought stress in pearl millet.

We examined ass... Read More about Root metaxylem area influences drought tolerance and transpiration in pearl millet in a soil texture dependent manner.

A novel root hair mutant, srh1, affects root hair elongation and reactive oxygen species levels in wheat. Frontiers in Plant Science, 15, Article 1490502. https://doi.org/10.3389/fpls.2024.1490502

Background: Root hairs are single-celled projections on root surfaces, critical for water and nutrient uptake. Here, we describe the first short root hair mutant in wheat (Triticum aestivum L.), identified in a mutagenized population and termed here...

Root Hairs: An under-explored target for sustainable cereal crop production (2024)
Journal Article
Tsang, I., Atkinson, J. A., Rawsthorne, S., Cockram, J., & Leigh, F. (2024). Root Hairs: An under-explored target for sustainable cereal crop production. Journal of Experimental Botany, 75(18), 5484–5500. https://doi.org/10.1093/jxb/erae275

To meet the demands of a rising human population, plant breeders will need to develop improved crop varieties that maximize yield in the face of increasing pressure on crop production. Historically, the optimization of crop root architecture has repr... Read More about Root Hairs: An under-explored target for sustainable cereal crop production.

Soil structure is a crucial soil physical property that determines a soil's ability to support the growth and development of plants. Soil compaction modifies soil structure by reducing pore space between soil particles thereby leading to a denser soi...

Organ loss occurs frequently during plant and animal evolution. Sometimes, non-functional organs are retained through evolution. Vestigial organs are defined as genetically determined structures that have lost their ancestral (or salient) function. D...
