Recent Advances in Flowering Time Control
The onset of flowering is an important step during the lifetime of a flowering plant. During the past two decades, there has been enormous progress in our understanding of how internal and external (environmental) cues control the transition to reproductive growth in plants. Many flowering time regulators have been identified from the model plant Arabidopsis thaliana. Most of them are assembled in regulatory pathways, which converge to central integrators which trigger the transition of the vegetative into an inflorescence meristem. For crop cultivation, the time of flowering is of upmost importance, because it determines yield. Phenotypic variation for this trait is largely controlled by genes, which were often modified during domestication or crop improvement. Understanding the genetic basis of flowering time regulation offers new opportunities for selection in plant breeding and for genome editing and genetic modification of crop species.
Epigenomics
Epigenetic modifications act on DNA and its packaging proteins, the histones, to regulate genome function. Manifest as the heritable methylation of DNA and as post-translational histone modifications, these molecular flags influence the architecture and integrity of the chromosome, the accessibility of DNA to gene regulatory components and the ability of chromatin to interact within nuclear complexes. While a multicellular individual has only one genome, it has multiple epigenomes reflecting the diversity of cell types and their properties at different times of life; in health and in disease. Relationships are emerging between the underlying DNA sequence and dynamic epigenetic states and the...
Predicative Forms in Natural Language and in Lexical Knowledge Bases
This book presents, by means of a number of articles, a survey and a set of projects in computational lexical semantics. The most crucial aspects of ongoing research on predicates are presented: verb semantic classifications, relations between syntax and semantics, Wordnet for Verbs, multilinguism, lexical knowledge bases and lexical acquisition, the generative lexicon. Predicative Forms in Natural Language and in Lexical Knowledge Bases is designed for professors, researchers and graduate students in the area of language processing and semantics.
Annual Plant Reviews, Senescence Processes in Plants
The scientific and economic significance of plant senescence means that much effort has been made to understand the processes involved and to devise means of manipulating them agriculturally. During the past few years there has been considerable progress in this regard, especially in the molecular, genetic and genomic aspects. Senescence has a tremendous impact on agriculture. For example, leaf senescence limits crop yield and biomass production, and contributes substantially to postharvest loss in vegetable and ornamental crops during transportation, storage and on shelves. In addition, proteins, antioxidants and other nutritional compounds are degraded during senescence. Senescing tissues ...

Firsthand
It’s time for a nonfiction feast. Firsthand takes readers into the lives and minds of genteel doomsayers, autistic activists, currency rebels, and audacious climate engineers. Follow spelling reformers, misunderstood criminals, Egyptian revolutionaries, pro-GMO environmentalists, and, of course, the Illinois man whose left hand was sewn onto his right wrist. This collection of David Wolman’s writing contains fifteen stories from Wired, Nature, The Atavist, the author’s books and more. Go ahead: dig in.
Genetics and Genomics of Brachypodium
Grasses dominate many natural ecosystems and produce the bulk calories consumed by humans either directly in the form of grains or indirectly through forage/grain fed animals. In addition, grasses grown as biomass crops are poised to become a significant source of renewable energy. Despite their economic and environmental importance, research into the unique aspects of grass biology has been hampered by the lack of a truly tractable experimental model system. Over that past decade, the small, annual grass Brachypodium distachyon has emerged as a viable model system for the grasses. This book describes the development of extensive experimental resources (e.g. whole genome sequence, efficient transformation methods, insertional mutant collections, large germplasm collections, recombinant inbred lines, resequenced genomes) that have led many laboratories around the world to adopt B. distachyon as a model system. The use of B. distachyon to address a wide range of biological topics (e.g. disease resistance, cell wall composition, abiotic stress tolerance, root growth and development, floral development, natural diversity) is also discussed.
Plant Biology
Plant Biology is a new textbook written for upper-level undergraduate and graduate students. It is an account of modern plant science, reflecting recent advances in genetics and genomics and the excitement they have created. The book begins with a review of what is known about the origins of modern-day plants. Next, the special features of plant genomes and genetics are explored. Subsequent chapters provide information on our current understanding of plant cell biology, plant metabolism, and plant developmental biology, with the remaining three chapters outlining the interactions of plants with their environments. The final chapter discusses the relationship of plants with humans: domestication, agriculture and crop breeding. Plant Biology contains over 1,000 full color illustrations, and each chapter begins with Learning Objectives and concludes with a Summary.
Plant Patterning
The contents cover many aspects, it is well illustrated and provides excellent integration of Morphology, Anatomy, Taxonomy, Physiology and Molecular Biology.
