🌳 RESEARCH 🌳

Exposing alder & oak to differing blue-to-red light ratios reveals species-specific responses in conductance & photosynthetic mechanisms, showing that water-use efficiency reductions occur via different physiological pathways - Diao et al.

🔗 doi.org/10.1093/jxb/...
#PlantScience 🧪
Fig. 8.Biochemical, mesophyll, and stomatal limitations on the photosynthetic response to increasing blue-light fraction for grey alder and holm oak. The biochemical (dAbiochem), mesophyll (dAmeso), and stomatal (dAstom) limitations were calculated according to Equation 9. (A) Grey alder. (B) Holm oak. At each %B level, dAbiochem, dAmeso, and dAstom were further normalized by multiplying them by dAn/dAcalc, where dAn is the difference between the maximum and current An. (C) The integrated relative limitations by Vcmax (maximum carboxylation rate of Rubisco; σbiochem), gm13 (total mesophyll conductance; σmeso), and gsc (stomatal conductance to CO2; σstom) across the different %B levels. All data are means (±SD), n=5 biological replicates.

🍃🌳🍂 #PhDAlert! MSc in #ForestEcology, #PlantPhysiology or #EnvironmentalSciences? Eager to apply a wide range of approaches, from #ecophysiology and experimental fieldwork to #RemoteSensing and modelling🛰️? We offer a #PhD position in Tree #Phenology: apply.refline.ch/273855/1788/... #ScienceJobs
Job offer: The Swiss Federal Institute for Forest, Snow and Landscape Research WSL is part of the ETH Domain. Approximately 600 people work on the sustainable use and protection of the environment and on the handling of natural hazards. The Research Unit Forest and Soil Ecology, which investigates how changing environmental conditions affect forest ecosystem functioning, is seeking a candidate to join the Ecosystem Ecology group starting on 1 January 2026 (or upon appointment) as a PhD candidate in Tree Phenology and Ecophysiology You will be working within the SNF funded project “From leaf-out to senescence: integrating daylight and temperature dynamics into phenological process-based models to enhance autumn phenology modelling”. Unlike leaf-out timing, leaf senescence is particularly challenging to predict, partly because many internal factors are involved and remain poorly understood. You will investigate how changing environmental conditions — including variations in temperature, daylight, and water availability — affect leaf senescence, with the goal of improving phenological models. To achieve this, you will combine manipulative experiments, long-term phenological observations, and large-scale remote sensing data. You will also apply both statistical and mechanistic modelling approaches and contribute to publishing results in international scientific journals. You hold a Master’s degree in in forest ecology, ecology, plant physiology, environmental science, or a related field. You are eager to apply a wide range of approaches, from ecophysiology and experimental fieldwork to remote sensing and modelling. You have a good command of English, work in a structured and independent manner, enjoy collaborating within a team and are comfortable using statistical software, preferably R. The workplace will be at WSL in Birmensdorf (approximately 20 minutes outside of Zurich), and the PhD enrolment will be at the University of Bern.

Congratulations to all authors @agbioworld.bsky.social👏

@plantteaching.bsky.social @cellpress.bsky.social
In this work, together with my wonderful co-authors (Yiran Li, Channapatna Prakash, and Zhangli Hu), we discuss how climate change-driven combined abiotic stresses threaten global crop productivity, and how panomics, AI-driven breeding, single-cell omics, and advanced phenotyping can guide the way for stress-smart crops of the future🌱 🔑 𝙆𝙚𝙮 𝙞𝙣𝙨𝙞𝙜𝙝𝙩𝙨: Panomics + AI = unlocking novel molecular targets & pathways Field-level validation + spatial/single-cell omics for real-world solutions Synthetic biology and epigenome editing as next-gen breeding strategies Crop wild relatives as hidden reservoirs of resilience Designing "genetic circuits" and "full-gene packages" for enhanced tolerance Ultimately, we propose panomics as a “social insurance” for crops, equipping them to withstand real-world stress combinations and secure sustainable agriculture in a changing climate 🌍✨
