Inducer of CBF expression 1 (ICE1) has long been acknowledged as a master regulator in the cold response, positively modulating the expression of cold-inducible <i>CBF</i> genes. However, recent studies that ICE1 is not involved in the regulation of <i>CBF</i> genes have challenged this established notion, prompting a critical reevaluation of the ICE1-CBF regulatory model. To address this controversy, <i>ice1-2</i> mutants were germinated on media containing 1% glucose and grown under short periodic conditions, ensuring comparable growth to wild-type (WT) plants before cold treatment. Surprisingly, our modified growth conditions revealed no discernible differences in the cold induction of <i>CBF</i> genes and their downstream targets between WT plants and <i>ice1-2</i> mutants. Moreover, cold-induced degradation of ICE1, mediated by the E3 ubiquitin ligase high expression of osmotically-responsive genes 1 (HOS1), was notably absent in two different <i>ICE1</i> transgenic plants. Consistent with this, cold-responsive gene expression profiling showed no difference between WT plants and <i>hos1</i> mutants. All our data strongly suggest that the HOS1-ICE1 regulatory module does not play a role in the cold regulation of the <i>CBF</i> signaling pathway in <i>Arabidopsis</i>.</p>","PeriodicalId":16762,"journal":{"name":"Journal of Plant Biology","volume":"7 1","pages":""},"PeriodicalIF":2.9,"publicationDate":"2024-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142250113","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Polycomb group (PcG) proteins in Polycomb repressive complexes (PRC1 and PRC2) especially regulate cellular and developmental processes in eukaryotes through epigenetic mechanisms. <i>Arabidopsis thaliana</i> has a fascinating name, LIKE HETEROCHROMATIN PROTEIN 1 (LHP1), called TERMINAL FLOWER 2 (TFL2). This protein was initially recognized as the plant equivalent of animal HP1 due to the presence of a chromo domain and a chromo shadow domain. It can bind to the trimethylated lysine 27 of histone H3 (H3K27me3) mark spread throughout the genome and regulate gene expression. This is crucial for the plant PcG system, which PRC2 establishes for epigenetic control. Although LHP1 has been found to perform diverse functions, it is still unclear whether these functions are carried out through similar mechanisms and whether it regulates the same target genes. This highlights the need for further research on LHP1 to better understand its mechanisms and functions. The following review provides detailed information about LHP1, which is closely linked to histone marks and the regulation of gene expression and explores how LHP1 influences flower timing and root development to improve crop traits. Recent progress in tomato and soybean production highlights the crucial role of LHP1 in shaping crop characteristics. The review suggests that LHP1 may control H3K27me3 in different plant species by regulating specific genes through epigenetic mechanisms.

In the last decades, intensive researches have revealed the molecular mechanisms underlying this phenomenon, particularly using <i>Arabidopsis</i> model plant. Most Brassicaceae family plants, including the <i>Arabidopsis</i>, require vernalization for floral transition. Brassicaceae family plants can be classified into two groups: seed vernalization responsive type and plant vernalization responsive type. Cabbage belongs to plant vernalization responsive type. Molecular details on plant vernalization responsive trait of cabbage on vernalization are still poorly understood. In this study, we conducted a transcriptomic analysis of the cabbage inbred line ‘BN2348’ in response to vernalization. Similar to the case of <i>Arabidopsis</i>, two <i>VIN3</i> homologs (<i>BoVIN3.C3</i> and <i>BoVIN3.C2</i>) were highly induced by the exposure to long-term cold in <i>B. oleracea</i>. Our transcriptome analysis identified that two <i>FT</i> homologs (<i>BoFT.C2</i> and <i>BoFT.C6</i>) and three <i>SOC1</i> homologs (<i>BoSOC1.1.C4</i>, <i>BoSOC1.2.C4</i>, and <i>BoSOC1.C3</i>) were functioning for the regulation of floral transition in <i>B. oleracea</i>. In addition, by phylogenic and syntenic analyses, a total of five <i>FLC</i> homologs, named <i>BoFLC1.a</i>, <i>BoFLC1.b</i>, <i>BoFLC2</i>, <i>BoFLC3</i>, and <i>BoFLC5</i>, were identified in the genome of <i>B. oleracea</i>.

As green plant vernalization type, it might suggest the existence of vernalization-insensitive <i>BoFLC</i> homologs in young seedlings might be the reason why cabbage exhibits longer exposure of cold compared to seed vernalization type plants such as Chinese cabbage and <i>Arabidopsis</i>.
