Recent Advances In Plant Science

This book compiles original and review advances from a number of different focuses and latest developments in the important field of plant biology/science from around the world. The publication will be a beneficial and valuable resource for many people and groups related to plant growth and development as well as teachers, researchers, commercial growers and advanced students of plant biological science. The proposed publication can be used in some interesting and unusual places such as biofuels, edible vaccine, phytoremediation and cosmetics.

Botany is a forerunning field of study that could address the foremost disputes facing humanity in the 21st century; coupled with the development of new tools and techniques, it could aid in finding solutions to diagnose these unsolved questions. The present book summarises the recent technological advances of plant science. This is a succinct, up-to-date, and relevant compilation based on the techniques used in plant science; this book embodies the recent knowledge of advanced techniques frequently being used from last few decades. There are twelve chapters summarised systematically that demonstrate: the suitability of Laser Produced Plasma Spectroscopy; potential of NMR spectroscopy in plant metabolomics; recent developments and applications of novel analytical techniques for the analysis of plant materials; chlorophyll as a fluorescence analysis and a technique to explore the photochemistry of photosystem II; drought stress and metabolomics in plants; heat shock on Bipolaris sorokiniana in cereal crops; salt stress on crops plants and their mitigation strategies; plant cell death by rumen-induced stress on plant in ruminant herbivores; the role of diazotrophs in maintaining plant health in agricultural fields; population biology of Rhizoctonia solani AG-1 IA from India; and biofilms as a home for microorganisms and genetically modified organism. This book will be helpful for researchers, academicians and students working on the related fields.

Plant biotechnology applies to three major areas of plants and their uses: (1) control of plant growth and development; (2) protection of plants against biotic and abiotic stresses; and (3) expansion of ways by which specialty foods, biochemicals, and pharmaceuticals are produced. The topic of recent advances in plant biotechnology is ripe for consideration because of the rapid developments in this ?eld that have revolutionized our concepts of sustainable food production, cost-effective alt- native energy strategies, environmental bioremediation, and production of pla- derived medicines through plant cell biotechnology. Many of the more traditional approaches to plant biotechnology are woefully out of date and even obsolete. Fresh approaches are therefore required. To this end, we have brought together a group of contributors who address the most recent advances in plant biotechnology and what they mean for human progress, and hopefully, a more sustainable future. Achievements today in plant biotechnology have already surpassed all previous expectations. These are based on promising accomplishments in the last several decades and the fact that plant biotechnology has emerged as an exciting area of research by creating unprecedented opportunities for the manipulation of biological systems. In connection with its recent advances, plant biotechnology now allows for the transfer of a greater variety of genetic information in a more precise, controlled manner. The potential for improving plant productivity and its proper use in agric- ture relies largely on newly developed DNA biotechnology and molecular markers.

This book is divided into five sections. The first section deals with the methodology and bioresource generation, techniques related to genetic engineering, and gene transfer to the nuclear genome and chloroplast genome. The new techniques of genome profiling and gene silencing are also presented. The second section of the book covers the classical aspect of plant biotechnology viz. tissue culture and micropropagation. Use of genetic engineering via Agrobacterium and direct transfer of DNA through particle bombardment to develop transformed plants in Artemisia, castor and orchids, and production of recombinant proteins in plant cells have been dealt with in the third section. The fourth section addresses the abiotic and biotic stress tolerance in plants. The basic biology of some of the stress responses, and designing plants for stress tolerance is discussed in this section. The fifth section examines medicinal plants and alkaloid production.

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.

The Alliums are some of the most ancient cultivated crops and include onions, garlic, leeks and other related plants. This book provides an up-to-date review of Allium science for postgraduates and researchers. It contains commissioned chapters on topics that have shown major advances particularly in the last ten years such as molecular biology, floriculture and biofertilizers.

In the recent years, the need to increase food production to meet the demands of rapidly increasing population from a limited land resource necessitated the use of intensive farming systems, with the inputs like narrow genetic base, high dose of fertilizers, pesticides, irrigation, monocropping, etc. which led to the development of diseases and pest. The effect of changing global climate, particularly the sharp increase in CO2 concentration, has increased the susceptibility of plants to pathogens and pests. Because of the chemicalization of agriculture, the age-old eco-friendly pest management practices like sanitation, crop rotation, mixed cropping, adjustment of date of planting, fallowing, summer ploughing, green manuring, composting, etc. are not being practiced, affecting the crops adversely. This has encouraged researchers to look for eco-friendly and novel approaches for pest management. The information on recent advances in crop protection (involving bacteria, fungi, nematodes, insects, mites and weeds) is scattered. The book delves upon the most latest developments in crop protection such as avermectins, bacteriophages, biofumigation, biotechnological approaches; bio-priming of seeds; disguising the leaf surface; use of non-pathogenic strains, plant defense activators, plant growth promoting rhizobacteria, pathogenesis-related proteins, strobilurin fungicides, RNA interference, and variety of mixtures/cultivar mixtures/multilines; soil solarization; biointensive integrated pest management; among several others (fusion protein-based biopesticides, seed mat technology and environmental methods). This book is a ready reference for students, policy-makers, scientists, researchers and extension workers.

Faster progress in plant biology research could benefit agriculture, the environment, medicine, and our understanding of basic biological processes. This book clearly and directly describes the impediments to greater achievements in plant science and suggests solutions. It presents an innovative plan that would create a comprehensive federal system of management and financial support for plant biology research and training.
