Epigenetic mechanisms are integral to plant growth, development, and adaptation to environmental stimuli. Over the past two decades,our comprehension of these complex regulatory processes has expanded remarkably, producing a substantial body of knowledge on both locus-specific mechanisms and genome-wide regulatory patterns. Studies initially grounded in the model plant Arabidopsis have been broadened to encompass a diverse array of crop species, revealing the multifaceted roles of epigenetics in physiological and agronomic traits. With recent technological advancements, epigenetic regulations at the single-cell level and at the large-scale population level are emerging as new focuses. This review offers an in-depth synthesis of the diverse epigenetic regulations, detailing the catalytic machinery and regulatory functions. It delves into the intricate interplay among various epigenetic elements and their collective influence on the modulation of crop traits. Furthermore, it examines recent breakthroughs in technologies for epigenetic modifications and their integration into strategies for crop improvement. The review underscores the transformative potential of epigenetic strategies in bolstering crop performance, advocating for the development of efficient tools to fully exploit the agricultural benefits of epigenetic insights.

Neural Regeneration Research 2025年第6期20卷 1735-1748页

Dysregulation of neurotransmitter metabolism in the central nervous system contributes to mood disorders such as depression, anxiety, and post–traumatic stress disorder. Monoamines and amino acids are important types of neurotransmitters. Our previous results have shown that disco-interacting protein 2 homolog A(Dip2a) knockout mice exhibit brain development disorders and abnormal amino acid metabolism in serum. This suggests that DIP2A is involved in the metabolism of amino acid–associated neurotransmitters. Therefore, we performed targeted neurotransmitter metabolomics analysis and found that Dip2a deficiency caused abnormal metabolism of tryptophan and thyroxine in the basolateral amygdala and medial prefrontal cortex. In addition, acute restraint stress induced a decrease in 5-hydroxytryptamine in the basolateral amygdala. Additionally, Dip2a was abundantly expressed in excitatory neurons of the basolateral amygdala, and deletion of Dip2a in these neurons resulted in hopelessness-like behavior in the tail suspension test. Altogether, these findings demonstrate that DIP2A in the basolateral amygdala may be involved in the regulation of stress susceptibility. This provides critical evidence implicating a role of DIP2A in affective disorders.

The genome of rice dwarf phytoreovirus (RDV) is composed of 12 double-stranded RNA segments, of which segment S6 encodes a non-structural protein Pns6 identified as the movement protein. In this report, Pns6 with a 6-histidine tag at the N-terminal was expressed in E. coli after induction under low temperature (18℃) and low concentration (0.4 mmol/L and 0.2 mmol/L) of IPTG, and then purified by Ni-chelated affinity chromatography. Stability analysis indicated that the expressed HisPns6 protein was stable at 37℃ after 24 h treatment. This recombinant protein was then used to make monoclonal antibody. Total 18 hybridoma clones were obtained. The specificity of antibodies was tested by Western blot using native Pns6 extracted from RDV-infected rice leaves, and 15 positive clones were confirmed. Mapping of the antigenic sites of Pns6 using antibodies showed that the most sensitive antigen determinant is located in the C-terminal region (the 296th-509th amino acids) of Pns6, which is confirms bioinformatics analysis.

We used our collection of Arabidopsis transcription factor （TF） ORFeome clones to construct protein microarrays containing as many as 802 TF proteins. These protein microarrays were used for both protein-DNA and proteinprotein interaction analyses. For protein-DNA interaction studies, we examined AP2/ERF family TFs and their cognate cis-elements. By careful comparison of the DNA-binding specificity of 13 TFs on the protein microarray with previous non-microarray data, we showed that protein microarrays provide an efficient and high throughput tool for genome-wide analysis of TF-DNA interactions. This microarray protein-DNA interaction analysis allowed us to derive a comprehensive view of DNA-binding profiles of AP2/ERF family proteins in Arabidopsis. It also revealed four TFs that bound the EE （evening element） and had the expected phased gene expression under clock-regulation, thus providing a basis for further functional analysis of their roles in clock regulation of gene expression. We also developed procedures for detecting protein interactions using this TF protein microarray and discovered four novel partners that interact with HY5, which can be validated by yeast two-hybrid assays. Thus, plant TF protein microarrays offer an attractive high-throughput alternative to traditional techniques for TF functional characterization on a global scale.

Co-suppression in transgenic Petunia hybrida expressing chalcone synthase A (chsA)

引用

Science China(Life Sciences) 2001年第6期44卷 661-668页

作者：李艳惠有为张仲凯黄兴奇李毅 peking-yale joint Center for plant molecular genetics and agrobiotechnology National Laboratory of Protein Engineering and Plant Genetics Engineering College of Life Sciences Peking University Beijing 100871 China

Chalcone synthase A is a key enzyme in the anthocyanin biosynthesis pathway. Expression of chsA gene in transgenic Petunia hybrida resulted in flower color alterations and co-suppression of transgenes and endogenous genes. We fused the β-glucuronidase (uidA) gene to the C-terminal of chsA gene, and transferred the fusion gene into Petunia hybrida via Agrobacterium tumefaciens. GUS histochemical staining analysis showed that co-suppression occurred specifically during the development of flowers and co-suppression required the mutual interaction of endogenous genes and transgenes. RNA in situ hybridization analysis suggested that co-suppression occurred in the entire plant, and RNA degradation occurred in the cytoplasm.

GAMT2 Encodes a Methyltransferase of Gibberellic Acid That is Involved in Seed Maturation and Germination in Arabidopsis

引用

Journal of Integrative plant Biology 2007年第3期49卷 368-381页

作者： Shufan Xing Genji Qin Yan Shi Zhangliang Chen Hongya GU Li-Jia Qu National Laboratory for Protein Engineering and plant Genetic Engineering Peking-Yale Joint Research Center for Plant Molecular Genetics and AgroBiotechnology College of Life Sciences Peking University Beijing 100871 China National plant Gene Research Center (Beijing) Beijing 100101 China

Salicylic acid methyltransferase （SAMT）, benzoic acid methyltransferase （BAMT） and theobromine methyltransferase （TH）（henceforth, SABATH） family proteins belong to a unique class of mehtyltransferase that can methylate small molecular compounds Including indole-3-acidic acid （IAA）, salicylic acid （SA） and jasmonic acid （JA）, in plants. Here we report that the GAMT2 protein, which has 34.2% similarity with IAMT1 in the amino acid sequence, can methylate gibberellic acid （GA）. Biolnformatics analysis suggests that GAMT2 may be able to methylate one molecule larger than SA. GAMT2 is predominantly expressed in the developing seed embryo and endosperm in Arabidopsis. During seed germination, the expression of GAMT2 decreases until the cotyledons expand out of the seed coat. Overexpression of GAMT2 in Arabidopsis resulted in multiple phenotypes, including dwarfism, retarded growth, late flowering, and reduced fertility, which are similar to the phenotypes of GA-deficient mutants. Seed germination assay showed that GAMT2 overexpression in plants was hypersensitive to GA biosynthesis inhibitor （ancymidol） and abscisic acid （ABA） treatments, whereas the GAMT2 null mutant （SALK_075450） was slightly Insensitive to such treatments, suggesting that GAMT2 may methylate GA or ABA. Enzyme activity analysis indicated that GAMT2 was able to methylate GA3 into Methyi-GA3 in vitro, but could not methylate ABA. Microarray analysis on GAMT2 overexpression plants suggested that Methyl-GA may be an Inactive form of GA in Arabidopsis. These data suggest that GAMT2 Is Involved in seed maturation and germination by modulating GA activity.

Carotenoids play an important role in many physiological processes in plants and the phytoene desaturase gene （PDS3）encodes one of the important enzymes in the carotenoid biosynthesis pathway. Here we report the identification andanalysis of a T-DNA insertion mutant of PDS3 gene. Functional complementation confirmed that both the albino anddwarf phenotypes of the pds3 mutant resulted from functional disruption of the PDS3 gene. Chloroplast development wasarrested at the proplastid stage in the pds3 mutant. Further analysis showed that high level of phytoene was accumulatedin the pds3 mutant. Addition of exogenous GA3could partially rescue the dwarf phenotype, suggesting that the dwarfphenotype of the pds3 mutant might be due to GA deficiency. Microarray and RT-PCR analysis showed that disruptingPDS3 gene resulted in gene expression changes involved in at least 20 metabolic pathways, including the inhibition ofmany genes in carotenoid, chlorophyll, and GA biosynthesis pathways. Our data suggest that the accumulated phytoenein the pds3 mutant might play an important role in certain negative feedbacks to affect gene expression of diverse cel-lular pathways.
