Systems acclimation to osmotic stress in zygnematophyte cells Zygnematophytes are the closest algal relatives of land plants. They hold key information to infer how the earliest land plants overcame the barrage of terrestrial stressors, prime of which is osmotic...

Thanks for noticing!

Luckily, in both our algae (Zygnema and Mesotaenium) key (standard and osmotic-specific) stress-related proteins like LEA, AKR, ELIP, SuSy, AHA & tonoplast channels are strongly unregulated.

Algae under salt stress—(un)expected adaptation! 🧬🌱 With Tanya’s collaboration, we found that Mesotaenium adapts well but takes on a short filamentous form instead of its usual single-cell shape! One strategy? PMEs —but many unknown genes are at play.

Exciting findings! 🚀 With the collaborative work of Birgit & Lukas, we highlight the crucial role of FLAs in osmotic & ionic stress response in our algae. While their exact mechanism remains a mystery, our results point to PTMs of sugar groups. Also noteworthy: XTHs are strongly upregulated! 🧬✨
