UV RESISTANCE LOCUS 8 signalling enhances photosynthetic resilience to herbicide‐induced damage in Arabidopsis thaliana

open access: yesNew Phytologist, EarlyView.
Summary Perception of low irradiance ultraviolet B (UV‐B) light (280–315 nm) by the UV RESISTANCE LOCUS 8 (UVR8) photoreceptor initiates signalling pathways that enhance plant defences to UV‐B damage, mitigating the effects of higher photon irradiances.

Old player, new roles: defining the role of the plastidial phosphorylase

open access: yesNew Phytologist, EarlyView.
Summary The plastidial phosphorylase (Pho1 or Phs1; E.C. 2.4.1.1) is a ubiquitous enzyme among plants that catalyzes the formation and degradation of glucans. Although the first report connecting Pho1 with starch metabolism came out > 80 years ago, its precise role is still a matter of debate.

Phenotypical Expression of Maize Seedlings from Lines with the “Tallos Gemelos” Trait [PDF]

open access: yesAdvances in Botany, 2015
In the Colegio de Postgraduados in Mexico, we have generated lines of maize (Zea mays L.) with the particularity that from a seed two or more stalks emerge and develop normally, calling that character “tallos gemelos.” This trait possibly modifies the proportions of the constituent tissues of the seed and could increase the nutritional and ...

Mechanisms driving functional divergence of transcription factor paralogs

open access: yesNew Phytologist, EarlyView.
Summary Transcription factors (TFs) are core components of the regulatory toolkits that control gene expression. The sophistication of these regulatory toolkits dramatically increased during Eukaryotic evolution, accomplished in part by the duplication of existing TFs and the subsequent repurposing of these new paralogs. This process, termed functional

Local adaptation of both plant and pathogen: an arms‐race compromise in switchgrass rust

open access: yesNew Phytologist, EarlyView.
Summary In coevolving species, parasites locally adapt to host populations as hosts locally adapt to resist parasites. Parasites often outpace host local adaptation since they have rapid life cycles, but host diversity, the strength of selection, and external environmental influence can result in complex outcomes.
