Furthermore, mycorrhizal fungi can form common mycelial networks (CMNs) that simultaneously interconnect multiple plants. Increasing lines of evidence suggest that CMNs can function as conduits, transferring stress-related systemic signals between plants. Between-plant signaling mediated by haustoria and CMNs likely has a profound impact on plant interactions with other organisms and adaptation to environmental factors.

Most chloroplast proteins are imported from the cytosol via multiprotein translocons in the outer and inner envelope membranes (the TOC and TIC complexes, respectively), or via one of several noncanonical pathways, and then sorted by different systems to organellar subcompartments. Chloroplast proteolysis is equally complex, involving the concerted action of internal proteases of prokaryotic origin and the nucleocytosolic ubiquitin-proteasome system (UPS). The UPS degrades unimported proteins in the cytosol and chloroplast-resident proteins via chloroplast-associated protein degradation (CHLORAD). The latter targets the TOC apparatus to regulate protein import, as well as numerous internal proteins directly, to reconfigure chloroplast functions in response to developmental and environmental signals.</p>","PeriodicalId":8335,"journal":{"name":"Annual review of plant biology","volume":"74 ","pages":"259-283"},"PeriodicalIF":23.9,"publicationDate":"2023-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9514861","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}

Given their ability to change the chromatin status quo, SWI/SNF remodelers are critical for cell fate reprogramming with pioneer and other transcription factors, for responses to environmental challenges, and for disease prevention. Recent cryo-electron microscopy and mass spectrometry approaches have uncovered different subtypes of SWI/SNF complexes with unique properties and functions.
