Journal Article
Shah, F. M., Razaq, M., Ali, Q., Shad, S. A., Aslam, M., & Hardy, I. C. W. (2019). Field evaluation of synthetic and neem-derived alternative insecticides in developing action thresholds against cauliflower pests. Scientific Reports, 9, doi:10.1038/s41598-019-44080-y

Synthetic chemical pesticides can enhance crop yields but also have undesired effects. Alternative ‘botanical insecticides’ may also have non-target effects on pollinators and biocontrol services. Employing action thresholds (ATs) can reduce pesticid... Read More

A core mechanism for specifying root vascular pattern can replicate the anatomical variation seen in diverse plant species (2019)
Journal Article
Mellor, N., Vaughan-Hirsch, J., Kümpers, B. M., Help-Rinta-Rahko, H., Miyashima, S., Pekka Mähönen, A., …Bishopp, A. (2019). A core mechanism for specifying root vascular pattern can replicate the anatomical variation seen in diverse plant species. Development, 146, doi:10.1242/dev.172411

Pattern formation is typically controlled through the interaction between molecular signals within a given tissue. During early embryonic development, roots of the model plant Arabidopsis thaliana have a radially symmetric pattern, but a heterogeneou... Read More

A regulatory module controlling GA-mediated endosperm cell expansion is critical for seed germination in Arabidopsis (2018)
Journal Article
Sánchez-Montesino, R., Bouza-Morcillo, L., Marquez, J., Ghita, M., Duran-Nebreda, S., Gómez, L., …Oñate-Sánchez, L. (2019). A regulatory module controlling GA-mediated endosperm cell expansion is critical for seed germination in Arabidopsis. Molecular Plant, 12(1), 71-85. doi:10.1016/j.molp.2018.10.009

A key component of seed germination is the interplay of mechanical forces governing embryo growth and the surrounding restraining endosperm tissue. Endosperm cell separation is therefore thought to play a critical role in the control of this developm... Read More

Methane transport in agricultural soil after injection of isotopically-enriched methane in the sub-surface (2018)
