Article Synopsis
- The assembly of specific cell wall polysaccharides is vital for plant growth and requires the complex of RAPID ALKALINIZATION FACTOR 4 (RALF4) and LEUCINE-RICH REPEAT EXTENSIN 8 (LRX8) for cell wall integrity during pollen tube development.
- The LRX8-RALF4 complex has a unique heterotetrametric structure that interacts specifically with demethylesterified pectins, influenced by the charge of the RALF4's surface.
- This interaction helps organize the cell wall polymers into a necessary reticulated network, highlighting RALF4's crucial dual role in both structural support and signaling during
The () gene in and is required for arbuscular mycorrhizal (AM) symbiosis. The moss has a close homolog (, ), although it does not form AM. Here, we explore the phylogeny of and in land plants, and study the expression and developmental function of in We show that is expressed primarily in the protonema, the early filamentous stage of moss development, and later in rhizoids arising from the leafy gametophores and in adult phyllids.
