An urban evolved invasive plant tolerates experimental climate change

📖 nph.onlinelibrary.wiley.com/doi/10.1002/...
by Flory et al.

Societal Impact Statement also available in ES, HR and ZH

#PlantScience

Urban sites had lower soil moisture, were hotter, and had more impervious surface than rural sites, and invasive plants were smaller at urban sites and more urbanized sites.

Exciting progress at MSU! 🌱

The Rhee Lab’s new semi-field research site is ready for C-SPIRIT pennycress experiments investigating plant responses to drought and candidate compounds.

We can’t wait to see C-SPIRIT research take root here!

Food plants are vital to human and planetary health, but their diversity is threatened, making food security, nutrition, and environmental goals more difficult to achieve.

🌱🧬 BRIEF COMMUNICATION 🧬🌱

Conserved residues within the swapped N-terminal transmembrane domain are essential for PDCT function, and co-expression of complementary inactive N- and C-terminal PDCT mutants partially restores activity - Balogh et al.

🔗 doi.org/10.1093/jxb/...
#PlantScience 🧪

Fig. 1 (shortened, full legend in paper): Sequence and structural analysis of PDCT and targeted mutagenesis of GmPDCT1. (A) Sequence alignment of eight selected, characterized PDCTs. Alignments were performed using ClustalOmega and visualized with ESPript3.2. Regions corresponding to the eight α-helices (coloured in rainbow colours; transmembrane, with black boxes; peripheral, no box) that make up the structure are annotated below. The conserved motifs typical of LPT proteins, C2 (SGH) and C3 (HXXXD), are highlighted in pink. Red arrows above the alignments indicate the residues targeted for mutagenesis, including E75 and D89 (this study) and D230 (Ulch et al., 2025). (B) Predicted structure (by AlphaFold 3) of GmPDCT1 as an N-terminal domain-swapped homodimer. The structure is shown as a cartoon, with key α-helices (α1–8) of one protomer identified and coloured in a rainbow scheme. Note that α2 from the N-terminus of one protomer completes the active site of its binding partner.

🌱🧬 RESEARCH 🧬🌱

This study identifies 11 soybean MYB transcription factors that regulate root suberin formation and reveals a hierarchical transcriptional network, providing new insights into how soybean roots establish protective barriers - Lu et al.

Fig. 4.Suberin deposition in soybean hairy roots overexpressing GmMYB genes. Hairy roots were harvested 15 days after induction, and tissues were sampled 2 cm from the root tip. Suberin deposition was visualized by fluorol yellow (FY088) staining in soybean hairy roots from the empty-vector control (EV) and 11 GmMYB overexpression lines. White arrows indicate ectopic suberin deposition in GmMYB41b, GmMYB41d, GmMYB74/102a, GmMYB74/102d, GmMYB53/92, and GmMYB93 overexpression lines. Scale bars = 50 μm.

The cover image shows Leontice incerta, a desert plant of Leonticeae (Berberidaceae) from Xinjiang, China. The bladderlike inflated fruits of L. incerta enable seed dispersal as tumbleweeds, which may be responsible for the extensive distribution of this genus across the open and dry habitats of Central Asia.

🌱🧬 Three structural studies reveal how receptor NUT reads a disulfide-locked cyclic SCREW peptide and recruits BAK1.

The cyclic region, not the C-terminus, forms the co-receptor interface—a distinct recognition mode for LRR-RKs. #plantscience @natplants.nature.com www.nature.com/articles/s41...

Conceptual figure describing how evidence from climate-smart land management studies links land-use systems, biogeochemical and biophysical outcomes, and social and economic contexts. A practice's climate-smart status is determined by its net climate impact (CO2, CH4, and N2O combined), while its adoption and durability at scale are separately shaped by context-specific social feasibility and economic viability, meaning a climate-smart practice may still see limited or uneven adoption depending on social and economic factors. In our review, we found uneven representation of studies across systems and incomplete greenhouse gas accounting, making it challenging to assess if, when, where, and how land management practices deliver climate benefits.

🌸 FLOWERING NEWSLETTER REVIEW 🌸

MADS-box transcription factors specify floral organ identity at the primordia stage, but also have late and spatially restricted roles in developing or mature floral organs, which Désert et al. explore in this review 🧬

🔗 doi.org/10.1093/jxb/...

#PlantScience 🧪

Fig. 1 (shortened, full legend in paper): Chosen examples of floral MADS-box transcripts or proteins with a precise spatial localization described in developing or mature floral organs. (A) Orchid Phalaenopsis perianth-code. The dorsal sepal, petal, lateral sepal, and lip express different combinations of OAGL6-1, OAGL6-2, OAP3-1, and OPA3-2 proteins, forming complexes with OPI (not displayed here). The lateral sepal shows a further zonation into its upper and lower part, expressing different protein complexes. Adapted from Hsu et al. (2021). (B) During rice floret development, OsMADS2 is distally and laterally enriched in the lodicules, which restricts lodicule elongation (for simplicity, only expression in the lodicule is depicted here). In the pistil, OsMADS2 expression is enriched in the ovary adaxial layers and ovule outermost layers. OsMADS4, in contrast, is uniformly expressed in the lodicule and in the ovule.
