| 1 | MicroRNAs in tomato plants显示文摘MicroRNAs (miRNAs) are a specialized class of small silencing RNAs that regulate gene expression in eukaryotes.In plants,miRNAs negatively regulate target mRNAs containing a highly complementary sequence by either mRNA cleavage or translational repression.As a model plant to study fleshy fruit ripening,miRNA studies in tomato have made great progress recently.MiRNAs were predicted to be involved in nearly all biological processes in tomato,particularly development,differentiation,and biotic and abiotic stress responses.Surprisingly,several miRNAs were verified to be involved in tomato fruit ripening and senescence.Recent studies suggest that miRNAs are related to host-virus interactions,which raises the possibility that miRNAs can be used as diagnostic markers for response to virus infection in tomato plants.In this review,we summarize our current knowledge systematically and advance future directions for miRNA research in tomato. | ZUO JinHua WANG YunXiang LIU HaiPing MA YuanZheng JU Zheng ZHAI BaiQiang FU DaQi ZHU Yi LUO YunBo ZHU BenZhong | 2011 | Science China(Life Sciences)2011，54，7： | 13 |
| 2 | Plant Small RNAs: Biogenesis, Mode of Action and Their Roles in Abiotic Stresses显示文摘Small RNAs (sRNAs) are 18-30 nt non-coding regulatory elements found in diverse organisms, which were initially identified as small double-stranded RNAs in Caenorhabditis elegans. With the development of new and improved technologies, sRNAs have also been identified and characterized in plant systems. Among them, micro RNAs (miRNAs) and small interfering RNAs (siRNAs) are found to be very important riboregulators in plants. Various types of sRNAs differ in their mode of biogenesis and in their function of gene regulation. sRNAs are involved in gene regulation at both transcriptional and post-transcriptional levels. They are known to regulate growth and development of plants. Furthermore, sRNAs especially plant miRNAs have been found to be involved in various stress responses, such as oxidative, mineral nutrient deficiency, dehydration, and even mechanical stimulus. Therefore, in the present review, we focus on the current understanding of biogenesis and regulatory mechanisms of plant sRNAs and their responses to various abiotic stresses. | Praveen Guleria Monika Mahajan Jyoti Bhardwaj Sudesh Kumar Yadav | 2011 | Genomics, Proteomics & Bioinformatics2011，9，6： | 10 |
| 3 | The epigenetic involvement in plant hormone signaling显示文摘The biosynthesis and signaling of plant hormones play a critical role in almost all biological processes.It is well-documented that phytohormones cross-talk with each other.Epigenetic mechanisms were suggested to regulate expression of downstream targets in hormone signaling pathways that help implement hormone functions.This new layer of complexities that integrate epigenetic information such as DNA methylation,chromatin remodeling,histone modification,microRNAs and siRNAs with plant hormone signaling and regulations of gene expression,has been gradually revealed.In this short review,the author tries to assemble recent progress to establish a molecular linkage between these two large and momentum research fields and also to help readers digest the literature. | ZHU YuXian | 2010 | Chinese Science Bulletin2010，55，21： | 4 |

| 6 | 甘蓝型油菜角果和种子发育相关的Bna-novel-miR432功能分析显示文摘为了探究miRNA在油菜花器官发育、角果和种子发育中的功能,本研究在甘蓝型油菜不同发育阶段角果和种子小RNA测序数据分析中,筛选到一个新的miRNA,命名为Bna-novel-miR432,并将其转化至拟南芥中进行功能分析.研究发现过表达Bna-novel-miR432拟南芥开花时间显著提前,并且发现其雄蕊发育存在缺陷,导致雌蕊授粉不完全.在对其花粉育性进行检测时发现过表达材料花粉育性显著降低.对角果发育统计发现,过表达拟南芥株系的角果变短,角果中种子数量显著减少,且部分角果存在败育的现象.此外,在种子发育方面,过表达材料种子中胚的发育也出现滞后的现象.以上结果表明,Bna-novel-miR432参与调控植物开花时间、雄蕊和花粉的发育以及果实的形成等生物学过程中发挥一定的调控功能. | 刘倩 王鑫 赵云 | 2022 | 四川大学学报(自然科学版)2022，59，5： | 0 |
