Over 40 years ago, in what is surelyone of the most famous throw-away lines in botany,Ledbetter and Porter (1963) suggested that the similar orientationsof cytoplasmic microtubules and structures considered to becellulose microfibrils in the cell wall was not coincidental.This notion led almost single-handedly to the present and enduringinterest amongst certain plant cell biologists in understandingthe role of microtubules in wall formation. And as a resultof this intense interest in such matters, it has become clearthat microtubules are not only just one componentamongst an ever-expanding array of 相似文献

Cell walls have long been recognized as important and uniquefeatures of plant cells, contributing not only to the architectureof plant organs but also to the control of growth, to the exclusionof pathogens and to the production and transmission of signallingmolecules. Gross measurements of plant cell composition establishedlong ago that the plant devotes a large 相似文献

Plant nutritionis ultimately an applied subject that seeks to understand theprocesses and mechanisms that underpin the uptake, assimilationand internal redistribution of nutrients by plants and thento use this information to improve the yield or quality of harvestedplant parts, be they grains, storage roots or leafy vegetables.The subject now also encompasses the understanding of the responsesof plants to nutrient toxicities (e.g. salinity) as well asnew topics such as metal hyperaccumulation and 相似文献

One can learn a lot about thegeochemistry of submerged soils in this book by Kirk. However,it is not, as the title implies, focused on the biogeochemistryof all submerged soils. In Chapter 1 Kirk gives a very briefoverview 相似文献

This book (a translation fromSchulze et al., 2002) is one of the most comprehensive textbooksof plant ecology so far. The authors aim to for the firsttime bring together and clearly organize the large subdisciplinesof plant ecology and, to a large extent they have succeeded.The book is well written, and its more than 500 illustrationsare beautifully laid out and well chosen to help the readerunderstand the theory. It is clearly suitable not only 相似文献

The InstantNotes series from Bios will probably be familiar to manyreaders. The series' success is evident in the second editionsthat are appearing, e.g. the current volumealbeit nowunder the Taylor and Francis label. Content This book does what it says on the label; it provides noteson (probably) all of the topics within the compass of present-dayplant biology. Primarily, it deals with anatomy,growth and development, physiology, reproduction, and economicuses and ecology of flowering plants (angiosperms). However,it does cover other phyla of the Kingdom Plantae (principallyin two taxonomy/evolution sections), and algae(along 相似文献

Highly specializedpollination systems, such as figs and their wasp or orchidsthat deceive bees in trying to make them mate with their floralorgans, are intuitively appealing to most people and have, therefore,gained far more attention both in popular and scientific literaturethan the more generalized pollination systems. For a long timethe dominant view was that many, or perhaps even most, plantpollinatorinteractions were specialized. In 1996 Waser and his colleaguestried to stir things up by writing an article in which theyargued that, in contrast to common belief, generalization waswidespread in plantpollinator systems. Ten 相似文献

The technique ofmicrocasting to unravel certain aspects of the three-dimensionalanatomy of animals (especially man) and plants goes back a longtime, but it is only recently that it has been perfected intoa fine art and a useful operational tool in plant anatomy, moreor less simultaneously by Jean-Pierre André in Franceand by Tomoyuki Fujii and co-workers in 相似文献

Sulphur metabolism of plants (I'll stick with British Englishspelling here) has always received less attention and attractedless funding than has research on nitrogen and phosphorus. Oneof the most important reasons no doubt is that, unlike nitrogenand phosphorus, sulphur availability to plants was rarely aproblem. As the post-World War II use of fertilizer 相似文献

Googling the termmolecular ecotoxicology results in less than 1000hits compared to more than 8·5 million for moleculargenetics. Hence, we are dealing with a rather new orless well-defined and less propagated field of science. Springer'sbook Molecular ecotoxicology of plants edited by H. Sandermannmay therefore fill a gap and it is unique in focusing on plants.A first introductory chapter sets the stage and tries to definethe term for a broad 相似文献

The left-hand side of equation (2·8), on p. 671, shouldread {1 (1 – 1)}–1/2 (21 – 1) rather than{(1 – 1)/1}1/2 (21 – 1). Reflecting this change,the left-hand side of equation (3·1) on the same pageshould be altered to , and the formula at the foot of p. 677 should be modified to {1 (1– 1)}–1/2 (21 – 1) + Op(n–1/2). No otherformula is affected, and the left-hand side of (2·8)is still increasing in 1. The numerical results, discussed in4, are influenced in minor ways. In the simulation study, absolutebias is reduced, and variance is either slightly increased orslightly decreased. In the real-data example, using the nonparametricapproach to analysis, mean squared error is further reduced,from 0·0011 to 0·0004. We are grateful to HiroKasahara and Katsumi Shimotsu for pointing out the error. 相似文献
