Plant cell separation and adhesion. Annual Plant Reviews, Volume 25.

Since the publication of Addicott's book Abscission (1982) andKoslowsky's book Shedding of Plant Parts (1973) no text bookhas appeared charting the subsequent progress in our understandingof the physiological and hormonal control of abscission andadhesion. The present volume is thus very timely and is an excellentexample of how molecular genetics had enhanced plant biologyat both basic and applied levels. While the authors fail totell us who this book is aimed at, there is no question thatit has intrinsic scientific interest and contributes stronglyto improving our understanding through new molecular experimentalmethods. It may also be important in agriculture and horticulture.However, in many chapters, the molecular and genetic informationis too introverted for readers whose interest is not primarilyin molecular genetics. A list of the titles of the chapters alone indicates the widescope of this     

Flowering and its manipulation. Annual Plant Reviews, Volume 20

Flowering is at the heart of plant biology. As the organ forsexual reproduction, the flower is the site of genetic recombinationand the source of genetic diversity and, through seed production,the site of multiplication and dispersal. Grains produced throughthe flowering process provide the components of staple dietsfor most of the world's population. Flowering has also had aprominent position in the molecular and genetic revolution inthe last two decades where models of flower development, suchas Arabidopsis and Antirrhinum, have provided leading insightsinto the mechanisms controlling development, morphogenesis,differentiation and     

Senescence processes in plants. Annual Plant Reviews, Volume 26.

This is a timely book that addresses many of the recent advancesin the plant senescence field. Senescence is an important developmentalstep in the life cycle of a plant or a plant organ and the processcan have a considerable influence on agriculture. Leaf senescenceis induced as part of plant development but can also be prematurelyinduced as a result of environmental changes or harvesting.Premature     

Cell cycle control and plant development. Annual Plant Reviews, Volume 32

There is an increasing awareness amongst the plant cell cyclecommunity that cell cycle genes interface with growth and development.Increasingly, snippets of information have shown that growthand development can be affected by over-expression of cell cyclegenes, although how this interface operates and how cell cyclegenes talk to developmental genes remains shrouded in mystery.In this one consolidated volume, a group of internationallyrenowned plant cell cyclists have turned their thoughts to theproblem. This is both welcome and timely. Not surprisingly,several authors tackle the cellular and organismic theoriesof development in relation to cell number and cell size.     

植物表观遗传学相关研究进展

表观遗传学是研究没有DNA序列变化,并且可以遗传的基因功能变化的学科。表观遗传在植物生长发育过程中起着极其重要的作用,现对其主要研究内容及相关进展进行综述。     

Special Issue on Plant Epigenetics

Epigenetics refers to gene regulation at the chromatin level. This can occur via modification of the DNA and the core proteins of the chromatin, histones （Liu et al., 2014）. In this issue, Reyes （2014） reviews recent advances in the roles of ATP-dependent chromatin-remodeling complexes on devel- opment, phytohormone response, and RNA-mediated silenc- ing and Da Ines et al. （2014） report the role of chromatin remodeling in homologous chromosome pairing. In addition, Over and Michaels （2014） discuss the emergent roles of plant histone linker proteins in gene regulation, cell division, and development.     

植物表观遗传与DNA甲基化

表观遗传在植物生长发育过程中起着极其重要的作用。甲基化是基因组DNA的一种主要表观遗传修饰形式,是调节基因功能的重要手段。介绍了植物体中胞嘧啶甲基化现象,RNA指导的DNA甲基化的信号分子、作用机制,以及与RNA介导的基因沉默机制之间的区别和RNA对转座子的表观控制。
