A nuclear pore complex (NPC) component, HIGH EXPRESSION OF OSMOTICALLY RESPONSIVE GENE 1 (HOS1), has been recognized as a negative regulator of plant cold responses and flowering. Here, we challenged the role of HOS1 in regulating flowering in response to salinity stress. Interestingly, we discovered that HOS1 can directly interact with and ubiquitinate transcription factor SPL9 (SQUAMOSA PROMOTER BINDING PROTEIN-LIKE 9) to promote its protein degradation in response to salinity stress. Moreover, we demonstrated that HOS1 and SPL9 antagonistically regulate plant flowering under both normal and salt stress conditions. HOS1 was further shown to negatively regulate the expression of SPLs and several key flowering genes in response to salinity stress.

Helix-loop-helix/basic helix-loop-helix (HLH/bHLH) complexes play important roles in fine-tuning plant development. However, the function of these genes in plant immunity and how they are regulated remain obscure. Here, we identified an atypical bHLH transcription factor, Oryza sativa (Os)HLH46, that interacts with rice receptor-like cytoplasmic kinase (RLCK) Os BRASSINOSTEROID-SIGNALING KINASE1-2 (OsBSK1-2), which plays a key role in rice blast resistance. OsBSK1-2 stabilized OsHLH46 both in vivo and in vitro. In addition, OsHLH46 positively regulates rice blast resistance, which depends on OsBSK1-2. OsHLH46 has no transcriptional activation activity and interacts with a typical bHLH protein, OsbHLH6, which negatively regulates rice blast resistance. OsbHLH6 binds to the promoter of OsWRKY45 and inhibits its expression, while OsHLH46 suppresses the function of OsbHLH6 by blocking its DNA binding and transcriptional inhibition of OsWRKY45. Consistent with these findings, OsWRKY45 was up-regulated in OsHLH46-overexpressing plants. In addition, the oshlh46 mutant overexpressing OsbHLH6 is more susceptible to Magnaporthe oryzae than is the wild type, suggesting that OsHLH46 suppresses OsbHLH6-mediated rice blast resistance. Our results not only demonstrated that OsBSK1-2 regulates rice blast resistance via the OsHLH46/OsbHLH6 complex, but also uncovered a new mechanism for plants to fine-tune plant immunity by regulating the HLH/bHLH complex via RLCKs.","PeriodicalId":195,"journal":{"name":"Journal of Integrative Plant Biology","volume":"66 12","pages":"2754-2771"},"PeriodicalIF":9.3,"publicationDate":"2024-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11622533/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142454304","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

More than 170 chemical modifications have been identified in RNAs, with N6-methyladenosine (m6A) being the most abundant modification in eukaryotic mRNAs. The addition and removal of m6A marks are catalyzed by methyltransferases (referred to as “writers”) and demethylases (referred to as “erasers”), respectively. In addition, the m6A marks in mRNAs are recognized and interpreted by m6A-binding proteins (referred to as “readers”), which regulate the fate of mRNAs, including stability, splicing, transport, and translation. Therefore, exploring the mechanism underlying the m6A reader-mediated modulation of RNA metabolism is essential for a much deeper understanding of the epigenetic role of RNA modification in plants. Recent discoveries have improved our understanding of the functions of m6A readers in plant growth and development, stress response, and disease resistance. This review highlights the latest developments in m6A reader research, emphasizing the diverse RNA-binding domains crucial for m6A reader function and the biological and cellular roles of m6A readers in the plant response to developmental and environmental signals.

The Zmski3 mutants showed retarded plant growth and constitutively activated defense responses, while the ZmSKI3 overexpression lines are more susceptible to Curvularia lunata and Bipolaris maydis. Consistently, the expression of defense-related genes was generally up-regulated, while expressions of growth-related genes were mostly down-regulated in leaves of the Zmski3-1 mutant compared to that of wild type. In addition, 223 differentially expressed genes that are up-regulated in Zmski3-1 mutant but down-regulated in the ZmSKI3 overexpression line are identified as potential target genes of ZmSKI3. Moreover, small interfering RNAs targeting the transcripts of the defense- and growth-related genes are differentially accumulated, likely to combat the increase of defense-related transcripts but decrease of growth-related transcripts in Zmski3-1 mutant.

Plastids are crucial organelles that respond to light, but the effects of light on plastid RNA processing following transcription remain unclear. In this study, we systematically examined the influence of light exposure on plastid RNA processing, focusing on RNA splicing and RNA editing. We demonstrated that light promotes the splicing of transcripts from the plastid genes rps12, ndhA, atpF, petB, and rpl2. Additionally, light increased the editing rate of the accD transcript at nucleotide 794 (accD-794) and the ndhF transcript at nucleotide 290 (ndhF-290), while decreasing the editing rate of the clpP transcript at nucleotide 559 (clpP-559). We have identified key regulators of signaling pathways, such as CONSTITUTIVELY PHOTOMORPHOGENIC 1 (COP1), ELONGATED HYPOCOTYL 5 (HY5), and PHYTOCHROME-INTERACTING FACTORs (PIFs), as important players in the regulation of plastid RNA splicing and editing. Notably, COP1 was required for GENOMES UNCOUPLED1 (GUN1)-dependent repression of clpP-559 editing in the light. We showed that HY5 and PIF1 bind to the promoters of nuclear genes encoding plastid-localized RNA processing factors in a light-dependent manner.

Here, we describe the CSC-interacting factor CASPARIAN STRIP MEMBRANE DOMAIN-LIKE1 (GhCASPL1), which contributes to SCW thickening by influencing CSC stability on the plasma membrane. GhCASPL1 is preferentially expressed in fiber cells during SCW biosynthesis and encodes a MARVEL domain protein. The ghcaspl1 ghcaspl2 mutant exhibited reduced plant height and produced mature fibers with fewer natural twists, lower tensile strength, and a thinner SCW compared to the wild type. Similarly, the Arabidopsis (Arabidopsis thaliana) caspl1 caspl2 double mutant showed a lower cellulose content and thinner cell walls in the stem vasculature than the wild type but normal plant morphology. Introducing the cotton gene GhCASPL1 successfully restored the reduced cellulose content of the Arabidopsis caspl1 caspl2 mutant. Detergent treatments, ultracentrifugation assays, and enzymatic assays showed that the CSC in the ghcaspl1 ghcaspl2 double mutant showed reduced membrane binding and decreased enzyme activity compared to the wild type. GhCASPL1 binds strongly to phosphatidic acid (PA), which is present in much higher amounts in thickening fiber cells compared to ovules and leaves. Mutating the PA-binding site in GhCASPL1 resulted in the loss of its colocalization with GhCesA8, and it failed to localize to the plasma membrane. PA may alter membrane structure to facilitate protein–protein interactions, suggesting that GhCASPL1 and PA collaboratively stabilize the CSC.

In this study, we identified a C2H2-type zinc-finger transcription factor, CitZAT4, the expression of which was markedly induced by ethylene. CitZAT4 directly binds to the CitPSY promoter and activates its expression, thereby promoting carotenoid biosynthesis. Transient expression in Satsuma mandarin fruit and stable transformation of citrus calli showed that overexpressing of CitZAT4 inhibited CitLCYE expression, thus inhibiting α-branch yellow carotenoid (lutein) biosynthesis. CitZAT4 overexpression also enhanced the transcript levels of CitLCYB, CitHYD, and CitNCED2, promoting β-branch orange carotenoid accumulation. Molecular biochemical assays, including yeast one-hybrid (Y1H), electrophoretic mobility shift (EMSA), chromatin immunoprecipitation quantitative polymerase chain reaction (ChIP-qPCR), and luciferase (LUC) assays, demonstrated that CitZAT4 directly binds to the promoters of its target genes and regulates their expression. An ethylene response factor, CitERF061, which is induced by ethylene signaling, was found to directly bound to the CitZAT4 promoter and induced its expression, thus positively regulating CitZAT4-mediated orange coloration in citrus fruit. Together, our findings reveal that a CitZAT4-mediated transcriptional cascade is driven by ethylene via CitERF061, linking ethylene signaling to carotenoid metabolism in promoting orange coloration in the flavedo of Satsuma mandarin fruit.

Knockout of GhMYB30D04 gene in cotton (KO) results in a reduction of GhLTPG1 transcripts with lower accumulation of PIPs, leading to shorter fibers and lower fiber yield. Conversely, GhMYB30D04 overexpression (GhMYB30D04-OE) causes richer PIPs and longer cotton fibers, mimicking the effects of exogenously applying PIPs on the ovules of GhMYB30D04-KO and wild type. Furthermore, GhMYB30D04 interacts with GhHD1, the crucial transcription factor of fiber initiation, to form an activation complex stabilized by PIPs, both of which upregulate GhLTPG1 expression. Comparative omics-analysis revealed that higher and extended expressions of LTPG1 in fiber elongation mainly correlate with the variations of the GhMYB30D04 gene between two cotton allotetraploids, contributing to longer fiber in G. babardense. Our work clarifies a mechanism by which GhHD1–GhMYB30D04 form a regulatory module of fiber elongation to tightly control PIP accumulation.
