The tobacco BY-2 cell system is a unique model cell line for the study of dynamic features of plant cells. As extension of Volume 53, Tobacco BY-2 Cells, which presented basic aspects of the cell system, this present volume provides a wealth of new approaches. Topics include: various aspects of the cell cycle and cellular dynamics using BY-2 cells; physiological and developmental aspects of BY-2 cells; recent developments in the knowledge of intracellular traffic of BY-2 cells; BY-2 cells as hosts for infectious diseases; dynamic features of mitochondrial fusion and division; BY-2 cells as tools to elucidate the biosynthesis of isoprenoids; recent developments in the omics of BY-2 cells; and novel techniques for handling BY-2 cells. This latest volume in the series is an invaluable source of information for scientists in basic and applied plant biology.

Medicinal and Aromatic Plants XII comprises 18 chapters. It deals with the distribution, importance, conventional propagation, micropropagation, tissue culture studies, and the in vitro production of important medicinal and pharmaceutical compounds in the following plants: Artemisia annua, Coriandrum sativum, Crataegus, Dionaea muscipula, Hyoscyamus reticulatus, Hypericum canariense, Leguminosae, Malva, Ocimum, Pergularia tomentosa, Phellodendron amurense, Sempervivum, Solanum aculeatissimum, S. chrysotrichum, S. kasianum, Stephania, Trigonella, and Vaccinium. It is tailored to the needs of advanced students, teachers, and research scientists in the fields of pharmacy, plant tissue culture, phytochemistry, biomedical engineering, and plant biotechnology in general.

It is our pleasure to present the 53rd volume of the Biotechnology in Agric- ture and Forestry (BAF) series. This is the second issue of the BAF series edited by the new editorial team consisting of Professors Horst Lorz, University of Hamburg, Hamburg, Germany, Jack Widholm, University of Illinois, Urbana, USA,and Toshiyuki Nagata,University of Tokyo,Tokyo,Japan. This series was originally founded by the late Professor Y. P. S. Bajaj,Delhi,India,in 1986. The current volume is somewhat unique, since in this volume only one plant cell line,the tobacco BY-2 cell line,is handled,while previous volumes mainly dealt with plants having certain economical importance. Nonetheless, the three editors of this volume,Professors Dirk Inze,Seiichiro Hasezawa and Toshiyuki Nagata,believe that most scientists who are working in the ?eld of plant s- ences will enjoy seeing this volume as a kind of source book of the unique tobacco BY-2 cells. Indeed,tobacco BY-2 cells have,over the years,gained the status as a model plant system,comparable to HeLa cells for human research. The current book is very timely because a wealth of basic knowledge on plant cells related to,e. g. ,cell division,cytoskeleton,cytokinesis,plant hormone s- naling,etc. ,has been gathered from experiments with this cell line. As re?ected in the contents,the accumulated knowledge of the BY-2 cell line is enormous and there is no other cell line that has been so important for progress in the plant sciences. Such knowledge should be shared with scientists from the ?elds of both applied and basic plant science.

Genome sequence studies have become more and more important for plant breeding. Brassicas and Legumes: From Genome Structure to Breeding comprises 16 chapters and presents both an overview and the latest results of this rapidly expanding field. Topics covered include: genome analysis of a flowering plant, Arabidopsis thaliana; the sequence of the Arabidopsis genome as a tool for comparative structural genomics in Brassicaceae; application of molecular markers in Brassica coenospecies; the molecular genetic basis of flowering time variation in Brassica species; quantitative trait loci for clubroot resistance in Brassica oleracea; structural differences of S locus between Brassica oleracea and Brassica rapa; Brassica and legume chromosomes; sequence analysis of the Lotus japonicus genome; introduction of an early flowering accession ‘Miyakojima’ MG-20 to molecular genetics in Lotus japonicus; genetic linkage map of the model legume Lotus japonicus; construction of a high quality genome library of Lotus japonicus; genome analysis of Mesorhizobium loti: a symbiotic partner to Lotus japonicus; molecular linkage map of the model legume Medicago truncatula; genetic mapping of seed and nodule protein markers in diploid alfalfa (Medicago sativa); mapping the chickpea (Cicer arietinum) genome: localization of fungal resistance genes in interspecific crosses.  

Somatic hybrids through the fusion of plant protoplasts have widened the genetic variability of cultivated plants. As "Somatic Hybridization in Crop Improvement I", published in 1994, this volume describes how this discipline can contribute to the improvement of crops. It comprises 24 chapters dealing with interspecific and intergeneric somatic hybridization and cybridization. It is divided into four sections:I. Cereals: Barley, rice, and wheat.II. Vegetables and Fruits: Arabidopsis, Asparagus, Brassica, chicory, Citrus, Cucumis, Diospyros, Ipomoea, and various Solanaceous species, e.g., tomato, potato, and eggplant.III. Medicinal and Aromatic Plants: Atropa, Dianthus, Nicotiana, and Senecio.IV. Legumes/Pasture Crops: Alfalfa.This book is tailored to the needs of advanced students, teachers and researchers in the fields of plant breeding, genetic engineering, and plant tissue culture.
