Abstract Chemicals and Solutions Leucine-rich repeat receptor-like kinases (LRR-RLKs) are well known to act in plant growth, development, and defense responses.Plant LRR-RLKs locate on cell surface to sense and initiate responsive signals to a variety of extracellular stimuli, such as microbe-associated molecular patterns (MAMPs) released from microorganisms.LRR-RLKs are also present in microbes and function in microbial growth and development, but their roles in communicating with hosts are largely unknown.A recent study published in Nature Communications uncovered that a microbial LRR-RLK, PsRLK6, is required for oospore development in the sexual reproduction of Phytophthora sojae, an oomycete pathogen that causes root and stem rot in soybean.

Meanwhile, PsRLK6 is recognized as a novel type of MAMP by an unknown plant LRR receptor-like protein and triggers immune responses in soybean, tomato, and Nicotiana benthamiana.The findings reveal dual roles of a pathogen LRR-RLK in determining both Apple Shaped Acrylic Plaque life through sexual reproduction and death through triggering plant immunity.
