Past research has focused on how plant immune receptors sense danger signals during infection and signaling mechanisms. How pathogens, particularly those that infect flowers and roots, breach physical barriers of different host tissues and establish niches for proliferation has received less attention. Recent advances indicate that different pathogens employ specialized mechanisms to manipulate the physiology, metabolism, growth, and development of specific host cells to breach various physical barriers and create a microenvironment suitable for pathogen proliferation and dissemination. Importantly, the plant immune system actively engages these processes to counter pathogenesis. Furthermore, emerging evidence increasingly points to different roles of specific plant cells in sensing the pathogen and cell-cell communication that is important for the establishment of immunity at the organism level.</p>","PeriodicalId":7944,"journal":{"name":"Annual review of cell and developmental biology","volume":" ","pages":"307-330"},"PeriodicalIF":11.4,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144207465","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nodal has become a paradigm for a morphogen that employs multiple mechanisms for tissue patterning, including concentration- and duration-dependent effects, feedback regulation, reaction-diffusion interactions, and scale invariance. Nodal signaling activates a broad set of target genes that specify cell types, remodel the intracellular and extracellular milieu, and drive cell movements and morphogenesis.

Here, we review recent advances in the regulation of protocadherin (Pcdh) and olfactory receptor (OR) gene clusters. These clusters present similar challenges in that cells must express a limited number of each type of gene stochastically. Probabilistic Pcdh and OR choice is accomplished through tunable enhancer-promoter interactions, but these interactions are regulated by distinct mechanisms. At the Pcdh locus, cohesin-mediated DNA loop extrusion dictates enhancer-promoter communication, whereas OR genes communicate with their enhancers through multichromosome assemblies involving the protein LDB1.

We compare how proteomes of condensates overlap within and across species, and we present functionally analogous condensates across organisms. Additionally, we discuss the potential role of condensation in early life, suggesting that phase separation could have facilitated the selection and concentration of prebiotic molecules, promoting essential biochemical processes.
