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.

In the intricate process of natural product biosynthesis, a metabolon can enhance metabolic flux by associating sequential enzymes. A fungal metabolon, comprising of flavin-dependent monooxygenase Spe F and P450 monooxygenase Spe G, is identified in the biosynthesis of spiro polycyclic alkaloids(+)-notoamide B and its diastereomer(+)-versicolamide B. Using notoamide E as a substance, Spe F/Spe G metabolon can control the stereoselectivity of its 2,3-epoxidation, followed by hydrogen atom ion at C-17 to generate reactive epoxide tau-m A with dienyl iminium unit. Subsequently,(+)-notoamide B and(+)-versicolamide B are produced via tandem nonenzymatic inverse-electron-demand Diels-Alder reaction and semipinacol rearrangement. This provides the first example of metabolon in the biosynthesis of spiro-prenylated indole alkaloids.

A new loss-of-function allele 28y reveals a role of ARGONAUTE1 in limiting asymmetric division of stomatal lineage ground cell

引用

Journal of Integrative plant Biology 2014年第6期56卷 539-549页

作者： Kezhen Yangy Min Jiangy Jie Le key laboratory of plant molecular physiology Institute of Botany the Chinese Academy of Sciences

In Arabidopsis thaliana L., stomata are produced through a series of divisions including asymmetric and symmetric divisions. Asymmetric entry division of meristemoid mother cellproduces two daughter cells, the smal er meristemoid and the larger sister cell, a stomatal lineage ground cell（SLGC）. Stomatal lineage ground cells can differentiate into epidermal pavement cells but have the potential to divide asymmetrical y, spacing divisions, to create satel ite meristemoids. Peptide ligands and TOO MANY MOUTHS （TMM） and ERECTA family receptors regulate the initiation of stomatal lineages, activity, and orientation of spacing divisions. Here, we reported that a natural mutant 28y displayed an increased stomatal density and index. Using map-based cloning, we identified mutation in ARGONAUTE1 （AGO1） as the cause of 28y phenotypes. Time-lapse tracing of stomatal lineage cells reveals that stomatal overproduction in 28y is caused by the excessive asymmetric spacing division of *** genetic results demonstrated that AGO1 acts down-stream of TMM and negatively regulates the SPCH transcripts, but in a brassinosteroid-independent manner. Upregulation of AGAMOUS-LIKE16 （AGL16） in 28y mutants suggests that AGO1 is required to restrict AGL16-mediated stomatal spacing divisions, an miRNA pathway in addition to ligand-receptor signaling modules.

plant villins: Versatile actin regulatory proteins

引用

Journal of Integrative plant Biology 2015年第1期57卷 40-49页

作者： Shanjin Huang Xiaolu Qu Ruihui Zhang key laboratory of plant molecular physiology Institute of Botany the Chinese Academy of Sciences

Regulation of actin dynamics is a central theme in cell biology that is important for different aspects of cell physiology. Villin, a member of the villin/gelsolin/fragmin superfamily of proteins, is an important regulator of actin. Villins contain six gelsolin homology domains （G1-G6） and an extra headpiece domain. In contrast to their mammalian counterparts, plant villins are expressed widely, implying that plant villins play a more general role in regulating actin dynamics. Some plant villins have a defined role in modifying actin dynamics in the pollentube; most of their in vivo activities remain to be ascertained. Recently, our understanding of the functions and mechanisms of action for plant villins has progressed rapidly, primarily due to the advent of Arabidopsis thaliana genetic approaches and imaging capabilities that can visualize actin dynamics at the single filament level in vitro and in living plant cells. In this review, we focus on discussing the biochemical activities and modes of regulation of plant villins. Here, we present current understand- ing of the functions of plant villins. Finally, we highlight some of the key unanswered questions regarding the functions and regulation of plant villins for future research.

Rice bZIP protein,REB,interacts with GCN4 motif in promoter of Waxy gene

引用

Science China(Life Sciences) 2002年第4期45卷 352-360页

作者：程世军洪孟民王宗阳 Shanghai Institute of plant physiology and National key laboratory of plant molecular Genetics Chinese Academy of Sciences Shanghai China

A bifactorial endosperm box (EB), which contains an endosperm motif (EM) and a GCN4 motif, was found in rice Wx promoter. EB was found in 5′ upstream region of many seed storage protein genes accounting for these genes expression exclusive in endosperm among various cereals. Many reports demonstrated that the bZIP transcription activators isolated from wheat, barley and maize, etc. regulate the gene expression through binding to the GCN4 motif. In this research, we showed that GCN4 sequence could be recognized by nuclear proteins extracted from immature rice seeds. Furthermore, a rice bZIP protein, REB was isolated by using PCR method and REB fusion protein was expressed in E. coli. The results of gel shift analysis showed that REB could recognize and bind to the GCN4 motif in the Wx gene in addition to binding to the target sequence in the promoter of α-globulin.

CRISPR Primer Designer:Design primers for knockout and chromosome imaging CRISPR-Cas system

引用

Journal of Integrative plant Biology 2015年第7期57卷 613-617页

作者： Meng Yan Shi-Rong Zhou Hong-Wei Xue National key laboratory of plant molecular Genetics Shanghai Institute of Plant Physiology and Ecologythe Chinese Academy of Sciences

The clustered regularly interspaced short palin- dromic repeats （CRiSPR）-associated system enables biologists to edit genomes precisely and provides a powerful tool for perturbing endogenous gene regulation, modulation of epigenetic markers, and genome architecture. However, there are concerns about the specificity of the system, especially the usages of knocking out a gene. Previous designing tools either were mostly built-in websites or ran as command-line programs, and none of them ran locally and acquired a user- friendly interface. In addition, with the development of CRISPR-derived systems, such as chromosome imaging, there were still no tools helping users to generate specific end-user spacers. We herein present researchers to design primers CRISPR Primer Designer for for CRISPR applications. Theprogram has a user-frfendly interface, can analyze the BLAST results by using multiple parameters, score for each candidate spacer, and generate the primers when using a certain plasmid. In addition, CRISPR Primer Designer runs locally and can be used to search spacer clusters, and exports primers for the CRiSPR-Cas system-based chromosome imaging system.

Rice caryopsis development Ⅰ: Dynamic changes in different cell layers

引用

Journal of Integrative plant Biology 2016年第9期58卷 772-785页

作者： Xiaoba Wu Jinxin Liu Dongqi Li Chun-Ming Liu key laboratory of plant molecular physiology Institute of BotanyChinese Academy of SciencesBeijing 100093China

Rice caryopsis as one of the most important food sources for humans has a complex structure that is composed of maternal tissues including the pericarp and testa and filial tissues including the endosperm and embryo. Although rice caryopsis studies have been conducted previously, a system- atic characterization throughout the entire developmental process is still lacking. In this study, detailed morphological examinations of caryopses were made during the entire 30- day developmental process. We observed some rapid changes in cell differentiation events and cataloged how cellular degeneration processes occurred in maternal tissues. The differentiations of tube cells and cross cells were achieved by 9 days after pollination （DAP）. In the testa, the outer integument was degenerated by 3 DAP, while the outer layer of the inner integument degenerated by 7 DAP. In the nucellus, all tissues with the exception of the nucellar projection and the nucellar epidermis degenerated in the first 5 DAP. By 21 DAP, all maternal tissues, including vascular bundles, the nucellar projection and the nucellar epidermal cells were degenerated. In summary, this study provides a complete atlas of the dynamic changes in cell differentiation and degeneration for individual maternal cell layers of rice caryopsis.
