Root architecture and leaf photosynthesis traits and associations with nitrogen-use efficiency in landrace-derived lines in wheat (2022)
Journal Article
Kareem, S. H., Hawkesford, M. J., DeSilva, J., Weerasinghe, M., Wells, D. M., Pound, M. P., Atkinson, J. A., & Foulkes, M. J. (2022). Root architecture and leaf photosynthesis traits and associations with nitrogen-use efficiency in landrace-derived lines in wheat. European Journal of Agronomy, 140, Article 126603. https://doi.org/10.1016/j.eja.2022.126603

Root system architecture (RSA) is important in optimizing the use of nitrogen. High-throughput phenotyping techniques may be used to study root system architecture traits under controlled environments. A root phenotyping platform, consisting of germi...

Non-invasive isotope-based hydrodynamic imaging in plant roots at cellular resolution (2022)
Presentation / Conference Contribution
Couvreur, V., Pascut, F. C., Dietrich, D., Leftley, N., Reyt, G., Boursiac, Y., Calvo-Polanco, M., Casimiro, I., Maurel, C., Salt, D. E., Draye, X., Wells, D. M., Bennett, M. J., & Webb, K. F. (2022, May). Non-invasive isotope-based hydrodynamic imaging in plant roots at cellular resolution. Presented at EGU General Assembly 2022, Vienna, Austria and online

A key impediment to studying water-related mechanisms in plants is the inability to noninvasively image water fluxes in cells at high temporal and spatial resolution. Here, we report that Raman microspectroscopy, complemented by hydrodynamic modellin... Read More about Non-invasive isotope-based hydrodynamic imaging in plant roots at cellular resolution.

Root system size and root hair length are key phenes for nitrate acquisition and biomass production across natural variation in Arabidopsis (2022)
Journal Article
De Pessemier, J., Moturu, T. R., Nacry, P., Ebert, R., De Gernier, H., Tillard, P., Swarup, K., Wells, D. M., Haseloff, J., Murray, S. C., Bennett, M. J., Inze, D., Vincent, C. I., & Hermans, C. (2022). Root system size and root hair length are key phenes for nitrate acquisition and biomass production across natural variation in Arabidopsis. Journal of Experimental Botany, 73(11), 3569-3583

The role of root phenes in nitrogen (N) acquisition and biomass production was evaluated in 10 contrasting natural accessions of Arabidopsis thaliana L. Seedlings were grown on vertical agar plates with two different nitrate supplies. The low N treat...

Systems approaches reveal that ABCB and PIN proteins mediate co-dependent auxin efflux (2022)
Journal Article
Mellor, N. L., Voß, U., Ware, A., Janes, G., Barrack, D., Bishopp, A., Bennett, M. J., Geisler, M., Wells, D. M., & Band, L. R. (2022). Systems approaches reveal that ABCB and PIN proteins mediate co-dependent auxin efflux. Plant Cell, 34(6), 2309–2327. https://doi.org/10.1093/plcell/koac086

Members of the B family of membrane-bound ATP-binding cassette (ABC) transporters represent key components of the auxin-efflux machinery in plants. Over the last two decades experimental studies have shown that modifying ABCB expression affects auxin...

Identification of QTL and underlying genes for root system architecture associated with nitrate nutrition in hexaploid wheat (2022)
Journal Article
GRIFFITHS, M., ATKINSON, J. A., Gardiner, L. J., SWARUP, R., POUND, M. P., WILSON, M. H., BENNETT, M. J., & WELLS, D. M. (2022). Identification of QTL and underlying genes for root system architecture associated with nitrate nutrition in hexaploid wheat. Journal of Integrative Agriculture, 21(4), 917-932. https://doi.org/10.1016/s2095-3119%2821%2963700-0

The root system architecture (RSA) of a crop has a profound effect on the uptake of nutrients and consequently the potential yield. However, little is known about the genetic basis of RSA and resource adaptive responses in wheat (Triticum aestivum L....

X-ray CT reveals 4D root system development and lateral root responses to nitrate in soil (2022)
Journal Article
Griffiths, M., Mellor, N., Sturrock, C. J., Atkinson, B. S., Johnson, J., Mairhofer, S., York, L. M., Atkinson, J. A., Soltaninejad, M., Foulkes, J. F., Pound, M. P., Mooney, S. J., Pridmore, T. P., Bennett, M. J., & Wells, D. M. (2022). X-ray CT reveals 4D root system development and lateral root responses to nitrate in soil. Plant Phenome Journal, 5(1), Article e20036. https://doi.org/10.1002/ppj2.20036

The spatial arrangement of the root system, termed root system architecture, is important for resource acquisition as it directly affects the soil zone explored. Methods for phenotyping roots are mostly destructive, which prevents analysis of roots o... Read More about X-ray CT reveals 4D root system development and lateral root responses to nitrate in soil.
