New paper out! 🌱
Plant defence isn’t a free upgrade.
We show phloem proteins can boost resistance to one attacker but increase susceptibility to another (incl. cyst nematodes).
Great collaboration 🙌

Fig. 1.Gas exchange and chlorophyll fluorescence from survey measurement. (A) CO2 assimilation rate, (B) stomatal conductance, and (C) operating efficiency of PSII (ΦPS2) of switchgrass were measured using an LI-6800 infrared gas analyzer with fluorometer. Filled circles are averages, with different colors representing the treatment when drought was implemented (n=20). Shaded regions represent developmental stages (gray=vegetative stage, red=flowering stage, blue=senescence stage). Bars on the circles represent the SEM. Means with different letters are significantly different according to an ANOVA and a Tukey’s post-hoc test (P<0.05).
🌾🔥 RESEARCH 🔥🌾
Drought timing reshapes switchgrass metabolism and biofuel quality: early drought boosts stress resilience but creates fermentation inhibitors such saponins, while late drought improves ethanol yield – Basyal et al.

💭 What would you research with €100M?
🌍 If you could study anything, what would it be?

Fig. 2.Micro-computed tomography (CT) of internal seed structure in wild cucumber. (A) Schematic representation of seed organization showing the three main components: internal tissues (yellow), air cavities (blue), and seed coat (red). (B, C) Longitudinal micro-CT sections of non-buoyant (B) and buoyant (C) seeds. (D, E) Transverse micro-CT sections of non-buoyant (D) and buoyant (E) seeds.
🥒 RESEARCH 🥒
Wild cucumber shows seasonally induced differences in seed structure and morphology, resulting in variable buoyancy and a dual dispersal strategy that may enhance its invasiveness across dynamic riparian environments – Dołkin-Lewko et al.

Fig. 1 (shortened, full legend in paper): Generation of transgenic Arabidopsis for identification of HIT4-interacting proteins using TurboID proximity labeling and MS. (A) Schematic diagram of the constructs used to generate transgenic Arabidopsis lines for TurboID labeling. The experimental construct contains a FLAG-TurboID-HIT4 fusion under control of the native HIT4 promoter, followed by a NOS terminator. The control construct contains a FLAG-TurboID fusion driven by the CaMV 35S promoter with a NOS terminator. (B) Western blot confirming the expression of FLAG-TurboID in both F-TbID/hit4-1 and F-TbID-HIT4/hit4-1 lines, whereas FLAG-TurboID-HIT4 was only detected in F-TbID-HIT4/hit4-1 plants. Rubisco large subunit (Rubisco LS) stained with Coomassie Brilliant Blue (CBB) served as a loading control. Uncropped blots are shown in Supplementary Fig. S1. (C) Complementation analysis of transgenic lines.
🌡️🧬 RESEARCH 🧬🌡️
Arabidopsis plants use a heat-responsive protein pair, HIT4 and PUB49, to loosen tightly packed DNA, helping them survive high temperatures through a newly discovered stress adaptation mechanism – Wu et al.

Fig. 10 (shortened, full legend in paper): Outline of the main differences in the N status of barley resulting from the joint action of elevated CO2 (ECO2) and temperature (ET) under drought conditions (CETE versus CATA) at the vegetative, anthesis, and maturity stages. The boxes at the bottom of the figure represent the environmental factor (ECO2 or ET) that had the greatest impact on the N status of barley at each developmental stage. The circles represent the key variables that define this N status, and the arrows indicate the direction of the effect. The colour of the letters inside the circles and the border lines indicate which was the primary environmental factor influencing it, blue for CO2, red for temperature, and grey for no effect. The colour of filled circles indicates the influence of the secondary environmental factor: blue for CO2 and red for temperature. Dotted lines suggest an effect on a certain variable to be investigqated in greater depth in future research.
🌾🌡️ RESEARCH 🌡️🌾
Under the future drought scenario, elevated CO2 leads to an imbalance in the C/N status, affecting barley N metabolism as phenology progresses, while elevated temperature hinders grain set – Yoldi-Achalandabaso et al.

Graphical abstract (shortened, full abstract in paper): Pollinators share the complex information and resource landscape of their host plants with herbivores. Yet, how sap feeders affect floral attractiveness to pollinators remains poorly understood, despite the critical role of this tripartite interaction in natural and agricultural ecosystems. In dioecious plant species, which display pronounced sexual dimorphism, these intricate interactions may vary in magnitude and direction between females and males, with significant implications for plant population dynamics and species co-evolution. In this study, we examined how infestation by the oligophagous aphid Brachycaudus lychnidis affects sex-specific interactions between the dioecious plant Silene latifolia and its specialist moth pollinator Hadena bicruris.
🌸🐜 RESEARCH 🐜🌸
Aphid infestation alters multiple visual and chemical floral traits in a plant sex-specific manner, leading to reduced attractiveness to moth pollinators in female plants, but not in males – Zill et al.

Fig. 1.Reverse vulnerability segmentation in Populus species is only observed in branches grown for >1 year in the field. Mean leaf (black) and stem (gray) optical vulnerability curves of (A) P. trichocarpa (n=3, mean ±SE) grown in a glasshouse; (B) in young single-year growth branches (circle) and older (4–6 year old) branches (triangle) of P. grandidentata (n=4, mean ±SE); and (C) in 3-year-old glasshouse- (circle) and field- (triangle) grown branches of P. deltoides (n=4, mean ±SE). The solid horizontal line represents 50% of the embolized xylem area.

Older, field-grown stems of poplars are more vulnerable to drought than leaves – Rimer et al.

Spring has truly sprung - in the planetary North - with this plant cutting about mattresses(!),
and how fungi can help to repurpose them.

Fig. 1 (shortened, full legend in paper): BEL11 transcript level and tuberization in vitro. (A) Verification of decreased BEL11 transcript level in lines 1, 10, 12, and 19 in 4-week-old in vitro cultivated plants under an LD photoperiod, normalized to the copy number of the reference transcript—polyubiquitin. The WT was set to 1. Three technical replicates were performed for each cDNA dilution (5× and 50×). (B) Timing of tuber onset. (C) Total tuber weight. (D) Average distance of tuber to stolon base. (E) Appearance of tuberizing stolons. For (B–E), node cuttings cultivated in vitro on TIM under darkness were evaluated 7, 14, 21, 28, and 35 DAT (B) and 35 DAT (C–E), respectively. The WT and four independent BEL11 RNAi lines: 1, 10, 12, and 19; for (A) n=3–11, for (B–D) n=28–30. For (A), error bars represent the standard deviations. Repeated measures ANOVA (A) or one-way ANOVA (C and D), Dunnett’s two-sided multiple-comparison test with control was used for statistical evaluation.
