„Baa-Varia“ - love it 😂
50 runaway sheep ram-paged through a German supermarket in rural Baa-varia, causing shear mania on Monday morning.

After breaking away from their 500-strong herd, the brazen sheep spent 20 minutes milling around in the Penny supermarket before ewe-turning and seeing themselves out.

At the end of 2024 I did a chronological round up of all the #plantscience in @science.org that year.
So how did 2025 pan out? This year, I’m grouping papers thematically instead of chronologically so read on to find out what exciting plant science came out over the last 12 months. (1/22)

The small GTPase MaROP10 interacts with MaRIC6 to regulate rhizobial infection in Melilotus albus
The symbiotic nitrogen fixation process between legume roots and rhizobia initiates at the root hairs. Rhizobia initially colonize the tip of the root hairs and induce its curling to become entrapped. However, the specific molecular mechanisms underlying root hair deformation and curling in response to rhizobial infection remain unclear. In this study, transcriptome analysis of wild-type JiMa389 and nodulation-deficient mutant jima61 of Melilotus albus, the Rho-like small GTPase MaROP10. Our results show that MaROP10 functions as an interacts with the Nod factor receptor NFR5 to regulate rhizobia-induced root hair deformation and infection thread formation during the early stages of rhizobial infection. To elucidate the mechanism of MaROP10, we further identified its downstream potential effector protein, MaRIC6, which positively regulates root hair deformation and infection thread formation. Taken together, MaROP10 likely integrates signals from the symbiotic receptor NFR5 to regulate downstream signaling pathways through its effector MaRIC6, thereby coordinating root hair deformation and infection thread development during the early stages of rhizobial infection.

Organelles do NOT have a single uniform pH.
And if you think they must, because “protons diffuse fast,” this paper is for you.

Network Inference Reveals Distinct Transcriptional Regulation in Barley against Drought and Fusarium Head Blight
We analyzed transcriptional networks in barley under single and combined Fusarium head blight (FHB) and drought stress. We applied complementary Weighted Gene Correlation Network Analysis (WGCNA) to identify stress-associated gene co-expression modules and GENIE3 to infer gene regulatory networks (GRNs). Integration of these frameworks revealed strong overlaps between co-expression modules and GRN clusters, highlighting robust regulatory patterns. Key transcription factors (TFs) were identified based on their weighted node degrees, reflecting their connectivity within the network. Independent analysis of paired transcription factor binding sites in promoter regions further supported predicted regulatory interactions. Notably, WRKY TFs emerged as central regulators of FHB response, consistent with their known roles in defense and secondary metabolite biosynthesis, but did not appear in drought-associated contexts. For bHLH or NAC TFs, individual family members steered FHB or drought responses but not both. Our findings demonstrate the power of combining network inference and motif enrichment to identify candidate TFs controlling stress responses, providing a solid foundation for targeted functional validation. ### Competing Interest Statement The authors have declared no competing interest.

We asked how can protein complexes diversify without compromising their function and explored this question using the plant #exocyst complex.
