There are many recent works on the topic of light and plant growth. These have not only been written by experts, but are also, in the main, written for experts (or, at least, for those who already have a fair understanding of the subject). This book has its origins in a six-week course in plant photophysiology, and its aim is to provide an introduction to the subject at an advanced undergraduate level. The imagined audience is simply a student who has asked the questions: In what ways does light affect plant growth, and how does it do it? The book is limited to aspects of photomorphogenesis. Photo synthesis is only considered where its pigments impinge on photo morphogenic investigations, or where its processes provide illustrative examples of particular interactions between light and biological material. Chapter 1 gives a general account of the various ways in which light affects plant development, and introduces topics which are subsequently covered in greater detail. In all the chapters, are special topic 'boxes', consisting of squared-off sections of text. These are simply devices for presenting explanatory background material, or material that I myself find particularly intriguing.

Light and Plant Development presents the Proceedings of the 22nd University of Nottingham Easter School in Agricultural Science. It discusses the spectral sensitivity of inhibition of flowering by light. It addresses the action spectrum for leaf enlargement and stem growth inhibition. Some of the topics covered in the book are the nature of the blue light photoreceptor in higher plants and fungi; re-examination of photochemical properties and absorption characteristics of phytochrome using high-molecular-weight preparations; and intermediates in the photoconversion of phytochrome. The high irradiance reaction is fully covered. The physiological evidence and localised responses, intracellular localisation and action of phytochrome are discussed in detail. The text describes in depth the immunological visualisation of phytochrome. The fractionation procedures and terminology are presented completely. A chapter is devoted to the photocontrol of enzyme levels. Another section focuses on the ribosomal RNA synthesis in developing leaves. The book can provide useful information to botanists, chemists, students, and researchers.

Scientific progress hinges on continual discovery and the extension of previous discoveries. The important series of volumes Discoveries in Plant Biology is specially compiled to provide a microcosmic atlas of the landmark discoveries that span the breadth of plant biology. Written by renowned plant biologists, the papers describe how classic discoveries were made and how they have served as the basis for subsequent breakthroughs. The 24 chapters in this third volume describe discoveries which contribute to the foundations of modern plant biology. The contributors, many of whom personally lit the way, bring readers back in time as if on a journey to retrace the paths and rethink the ideas they followed. These guided tours on how to decipher the natural laws will lead to an appreciation of the development of each field from simple concepts to an advanced multidisciplinary field of today. This volume will be of special interest to botanists, biochemists, plant physiologists and geneticists, and of general interest to those who are still fascinated by how discoveries are made.

The two-volume set LNAI 12084 and 12085 constitutes the thoroughly refereed proceedings of the 24th Pacific-Asia Conference on Knowledge Discovery and Data Mining, PAKDD 2020, which was due to be held in Singapore, in May 2020. The conference was held virtually due to the COVID-19 pandemic. The 135 full papers presented were carefully reviewed and selected from 628 submissions. The papers present new ideas, original research results, and practical development experiences from all KDD related areas, including data mining, data warehousing, machine learning, artificial intelligence, databases, statistics, knowledge engineering, visualization, decision-making systems, and the emerging applications. They are organized in the following topical sections: recommender systems; classification; clustering; mining social networks; representation learning and embedding; mining behavioral data; deep learning; feature extraction and selection; human, domain, organizational and social factors in data mining; mining sequential data; mining imbalanced data; association; privacy and security; supervised learning; novel algorithms; mining multi-media/multi-dimensional data; application; mining graph and network data; anomaly detection and analytics; mining spatial, temporal, unstructured and semi-structured data; sentiment analysis; statistical/graphical model; multi-source/distributed/parallel/cloud computing.
