TaWAKL8-2B, a wall-associated receptor-like kinase, mediates wheat rust resistance by linalool and ROS accumulation - Stress Biology Wall-associated receptor kinases (WAKs) and WAK-likes (WAKLs) play pivotal roles in regulating plant immunity, through multiple downstream signaling components. However, knowledge of WAKs/WAKLs in wheat immune responses to rust diseases remain limited. In this study, we identified and characterized a wheat WAKL, TaWAKL8-2B, which is upregulated during wheat resistance to both Puccinia striiformis f. sp. tritici (Pst) and Puccinia triticina (Ptt), indicating its role in wheat resistance to these two rust fungi. Transgenic wheat plants overexpressing TaWAKL8-2B exhibited enhanced resistance to stripe rust and leaf rust, accompanied by increased reactive oxygen species (ROS) production and up-regulated defense-related gene expression. Whereas, knockout TaWAKL8-2B reduced resistance to Pst and Ptt with less ROS accumulation, highlighting its positive role in wheat resistance. RNA-seq analysis revealed that 33 genes encoding ROS-scavenging enzymes were upregulated in TaWAKL8-2B-KO plants, explaining the reduced ROS. KEGG analysis enriched the monoterpenoid pathway, particularly the linalool biosynthesis pathway, with linalool synthases significantly downregulated in TaWAKL8-2B-KO plants. Correspondingly, linalool synthase content and linalool content decreased in knockout plants. Collectively, our findings uncover a novel mechanism by which TaWAKL8-2B positively modulates wheat rust resistance through modulating linalool biosynthesis and peroxidase activity. These results enhance our understanding of TaWAKL8-2B mediated immune signaling and offer a promising gene for improving wheat broad-spectrum resistance to rust diseases.

This is a collage with the main picture showing me, standing on snow in front of the Umeå Town Hall. I have integrated a picture from a thermometer showing that it had 21 °C in my flat, while it had -21 °C outside.

The picture was taken in the city center of Umeå, in the direction of City Hall Square. In the foreground, 2 "stones" are glowing and fairy lights are strung between the trees. The sky is dark blue.

Frost-covered branches shimmer in the sunlight, with intricate ice crystals visible against a blue sky. The blurred background shows a snowy mound and trees.

View from the windows of the Bildmuseet towards Öbacka. The landscape is blanketed in snow, including the frozen Ume River, creating a serene winter scene.

#Throwback to a year ago today: I arrived in Umeå, Sweden, for my research stay. The #Cava lab gave me a warm welcome (unlike the weather – it was -21 °C!). I loved learning HPLC-MS analysis of #peptidoglycan and exploring snowy Umeå. ❄️ 1/3

S1E2 | Laura Bacete | Plant Cell Wall Stiffness No Time To Read · Episode

I had the pleasure today of collaborating in the amazing podcast “No time to read” by @aribidopsis talking about my last paper on #cellwall integrity. Check it out here!

open.spotify.com/episode/4Mtz7r…

THESEUS1 modulates cell wall stiffness and abscisic acid production in Arabidopsis thaliana Plant cells can be distinguished from animal cells by their cell walls and high turgor pressure. Although changes in turgor and stiffness of cell walls seem coordinated, we know little about the mechanism responsible for coordination. Evidence has accumulated that plants, like yeast, have a dedicated cell wall integrity maintenance mechanism. This mechanism monitors the functional integrity of the wall and maintains it through adaptive responses when cell wall damage occurs during growth, development, and interactions with the environment. The adaptive responses include osmo-sensitive-induction of phytohormone production, defence responses as well as changes in cell wall composition and structure. Here, we investigate how the cell wall integrity maintenance mechanism coordinates changes in cell wall stiffness and turgor in Arabidopsis thaliana . We show that the production of abscisic acid (ABA), the phytohormone modulating turgor pressure and responses to drought, depends on the presence of a functional cell wall. We find that the cell wall integrity sensor THESEUS1 modulates mechanical properties of walls, turgor loss point and ABA biosynthesis. We identify RECEPTOR-LIKE PROTEIN 12 as a new component of cell wall integrity maintenance controlling cell wall damage-induced jasmonic acid production. Based on the results we propose that THE1 is responsible for coordinating changes in turgor pressure and cell wall stiffness. Significance statement Plants need to constantly adapt to a changing environment. This includes responses to biotic and abiotic stress. Key elements influencing the response to abiotic stress are the plant cell walls surrounding all cells and the phytohormone abscisic acid, which influences turgor pressure in plants. Turgor pressure in plant cells is much higher than in animal cells and a key driver of plant growth and development. Here we investigate the mechanism regulating cell wall stiffness and coordinating changes in stiffness and turgor. We characterize key elements of the mechanism and dissect its mode of action. This knowledge will enable us to pursue novel approaches to improve plant resistance to drought stress, which is crucial in a rapidly changing environment. ### Competing Interest Statement The authors have declared no competing interest.
