To control this disease, we prepared a slow-controlled release granule with an ethylicin-loaded core-shell structure. We analyzed the release characteristics, disease control efficacy, and impacts on soil microorganisms of ethylicin sustained release granules (ESRG) using high performance liquid chromatography, field experiments, and high-throughput sequencing. The ESRG exhibited a release rate of 46.86% at 20 °C and 57.49% at 35 °C on day 7 in soil with 10% moisture content, and 65.48% at 20 °C and 83.99% at 35 °C on day 7 in soil with 30% moisture content, demonstrating a dual response to temperature and moisture. In the field experiment, the relative control efficacy against tobacco bacterial wilt disease reached 42.33% on day 106. High-throughput sequencing results revealed that ESRG treatment enhanced bacterial diversity, while decreasing fungal diversity in the soil. Furthermore, ESRG treatment reduced the relative abundance of Ralstonia spp. and Fusarium spp. by 74.48% and 11.76%, respectively, at 15–20 cm depth. These findings can provide an important basis for ethylicin in the control of bacterial wilt disease.","PeriodicalId":16762,"journal":{"name":"Journal of Plant Biology","volume":"68 4","pages":"301-311"},"PeriodicalIF":0.0,"publicationDate":"2025-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s12374-025-09474-8.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147902907","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.

Several environmental factors such as altitude, physiognomy, and atmospheric temperature can affect the cultivation of <i>A. gigas</i>. Therefore, climate change is likely to influence the growth of <i>A. gigas</i> and the synthesis of its active ingredients. This study aimed to investigate the effects of different carbon dioxide concentrations and temperatures according to Shared Socioeconomic Pathways (SSP) scenarios (SSP1-2.6, SSP2-4.5, SSP3-7.0, SSP5-8.5) on the growth, physiological activities, and antioxidant activities of <i>A. gigas</i>. The photosynthesis rate of <i>A. gigas</i> under SSP1-2.6 and SSP5-8.5 conditions showed a steady reduction. Chlorophyll a, total chlorophyll, and carotenoid content decreased with the prolongation of the growing season under climate change conditions. Chlorophyll a fluorescence showed significantly higher RC/CSo, RC/ABS, PI_abs, SFI_abs in higher CO₂ concentration and temperature conditions. Only the total dry weight of <i>A. gigas</i> for each climate change scenario was significantly different, while the other growth characteristics were not significantly different because of high inter-individual variation. The antioxidant activities of <i>A. gigas</i> (DPPH, ABTS, and NO scavenging activities) under each of the different conditions showed no significant differences. The reducing power was significantly increased in SSP5-8.5 compared to SSP1-2.6. The differences in phenolic contents of both aerial parts and root parts were not statistically significant, while the flavonoid content of aerial parts increased depending on the temperature and CO₂ concentration.

In this study, we investigated the molecular mechanisms underlying pollen tube germination and elongation in rice, focusing on the interaction between OsPUB14 and OsMTD2 and its impact on reactive oxygen species (ROS) regulation. Expression studies revealed that <i>OsPUB14</i> was highly expressed in pollen and anther tissues, indicating its involvement in pollen function. We demonstrated that OsPUB14 belonging to group II U-box domain proteins, interacts with the kinase domain of OsMTD2 (a pollen-specific CrRLK1L member) and degrades it. This interaction subsequently reduces OsMTD2-mediated ROS generation. Moreover, the overexpression of <i>OsPUB14</i> resulted in decreased ROS levels and reduced fertility in rice plants, emphasizing its role in reproductive processes. Yeast two-hybrid screening identified OsCRK10P and OsNET2D as potential interactors of OsPUB14, further expanding our understanding of the regulatory networks associated with pollen development.

Flowers of <i>I. tenuifolia</i> began to open in late March and mid – April, and it exhibited a concentrated flowering pattern. Four types of bees were effective pollinators of this species. Flowers of <i>I. tenuifolia</i> are self-incompatible and not capable of autonomous selfing, outcross pollination ensures reproductive success in natural population.

Resource addition of water and fertilizer had no significant effect on seed production, but weather conditions affected pollinator activity and influence female reproduction through pollen availability.

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 summary, it emphasizes the importance of understanding LHP1’s role in plant development for breeding purposes.</p>","PeriodicalId":16762,"journal":{"name":"Journal of Plant Biology","volume":"21 1","pages":""},"PeriodicalIF":2.9,"publicationDate":"2024-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141503481","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}
