Abstract:
This timely volume brings together expert reviews of the recent significant advances in our knowledge and understanding of the organisation of the higher plant nucleus, and in particular in the relationship between nuclear organisation and the regulation of gene expression. Rapid progress has been made in a number of key areas over the last five years, including description and characterization of proteins of the nuclear envelope and nuclear pore complex, novel insights into nucleoskeletal structures, as well as developments related to chromatin organization, function and gene expression. These advances open the way for new research into areas such as stress tolerance, plant-pathogen interactions and ultimately crop improvement and food security. Continued research into plant nuclear structure, genome architecture and gene regulation also enriches our understanding of the origin and evolution of the nucleus and its envelope. Edited by world-class researchers in plant cell biology, and comprising contributions from internationally-renowned academics, this latest volume in the prestigious Annual Plant Reviews series brings together a wealth of knowledge in the burgeoning field of plant nuclear structure and genetics.   Annual Plant Reviews, Volume 46: Plant Nuclear Structure, Genome Architecture and Gene Regulation is a vital resource for advanced students, researchers and professionals in plant science and related disciplines. Libraries in all research establishments where plant science, biochemistry, molecular biology, genetics and genomics and agricultural science are taught and studied will find this excellent volume an essential addition to their shelf.
