Advances in Agronomy continues to be recognized as a leading
reference and first-rate source for the latest research in
agronomy. Each volume contains an eclectic group of reviews by
leading scientists throughout the world. As always, the subjects
covered are rich, varied, and exemplary of the abundant subject
matter addressed by this long-running serial.
White biotechnology, or industrial biotechnology as it is also
known, refers to the use of living cells and/or their enzymes to
create industrial products that are more easily degradable, require
less energy, create less waste during production and sometimes
perform better than products created using traditional chemical
processes. Over the last decade considerable progress has been made
in white biotechnology research, and further major scientific and
technological breakthroughs are expected in the future. Fungi are
ubiquitous in nature and have been sorted out from different
habitats, including extreme environments (high temperature, low
temperature, salinity and pH), and may be associated with plants
(epiphytic, endophytic and rhizospheric). The fungal strains are
beneficial as well as harmful for human beings. The beneficial
fungal strains may play important roles in the agricultural,
industrial, and medical sectors. The fungal strains and their
products (enzymes, bioactive compounds, and secondary metabolites)
are very useful for industry (e.g., the discovery of penicillin
from Penicillium chrysogenum). This discovery was a milestone in
the development of white biotechnology as the industrial production
of penicillin and antibiotics using fungi moved industrial
biotechnology into the modern era, transforming it into a global
industrial technology. Since then, white biotechnology has steadily
developed and now plays a key role in several industrial sectors,
providing both high value nutraceutical and pharmaceutical
products. The fungal strains and bioactive compounds also play an
important role in environmental cleaning. This volume covers the
latest developments and research in white biotechnology with a
focus on diversity and enzymes.
’n Regstreekse, voor die hand liggende en effektiewe gids tot boom-identifikasie.
Dié boek se titel sê dit alles! Hierdie bygewerkte tweede uitgawe verskaf ’n duidelike uiteensetting van hoe bome saamgestel is en waarna om op te let wanneer ’n boom geïdentifiseer word. Die boek bestaan uit twee dele:
- Deel 1 beskryf en illustreer duidelik die verskillende dele van ’n boom en hul rol in boomidentifikasie.
- Deel 2 bevat ’n sleutel tot 43 boomgroepe, gebaseer op maklik waarneembare stingel- en blaarkenmerke. Dit gee ’n duidelike oorsig van elke groep, sowel as die Suider-Afrikaanse boomfamilies wat in die onderskeie groepe verteenwoordig word. Talle kleurfoto’s en verduidelikende illustrasies ondersteun die teks wat dié handleiding toeganklik en gebruikersvriendelik maak.
Identifiseer die Bome van Suider-Afrika sal lesers toerus met ’n goeie begrip van die bou van bome en waarna hulle moet oplet om dit korrek te kan identifiseer.

Rock surfaces provide a challenging habitat for a broad diversity
of micro- or small-sized organisms. They interact with each other
forming complex communities as well with their substrate causing
biodeterioration of rock. Extreme fluctuation in light, temperature
and hydration are the main factors that determine the rock surface
habitats. The habitat includes epilithic organisms which thrive on
the surface without penetrating the rock, endolithic organisms
which live just beneath the surface using a thin layer of the rock
surface for protection against adverse conditions of the
environment (e.g. light protection, storage of water) and
chasmo-endolithic organisms which use fractures of the rock surface
for a more habitable environment. The book will provide an overview
of the various organismal groups, from prokaryotes to vascular
plants and arthropods, as well as survey organism-mediated
interactions with the rock surface. The latter include biogenic
weathering (biogeochemistry, state-of-the art imaging methods),
photosynthesis and nitrogen fixation at and inside the rock
surface.
This book systematically discusses the vegetation dynamics in
northern China since the LGM, with a focus on three dominant tree
species (Pinus, Quercus and Betula). By integrating methods of
palaeoecology, phylogeography and species distribution model, it
reconstructs the glacial refugia in northern China, demonstrating
that the species were located further north than previously assumed
during the LGM. The postglacial dynamics of forest distribution
included not only long-distance north-south migration but also
local spread from LGM micro-refugia in northern China. On the
regional scale, the book shows the altitudinal migration pattern of
the three dominant tree genera and the role of topographical
factors in the migration of the forest-steppe border. On the
catchment scale, it analyzes Huangqihai Lake, located in the
forest-steppe ecotone in northern China, to indentify the local
forest dynamics response to the Holocene climatic change. It shows
that local forests have various modes of response to the climate
drying, including shrubland expansion, savannification and
replacement of steppe. In brief, these studies at different
space-time scales illustrate the effects of climate, topography and
other factors on forest migration.
This fourth edition provides new and updated protocols on plant
cell, tissue, and organ cultures. Chapters are divided into five
parts that cover topics from general methodologies, statistical
analysis and contamination control, highly specialized techniques,
and laborious process of measuring the epigenetics changes in
tissue cultures. Written in the highly successful Methods in
Molecular Biology series format, chapters include introductions to
their respective topics, lists of the necessary materials and
reagents, step-by-step, readily reproducible laboratory protocols,
and tips on troubleshooting and avoiding known pitfalls.
Authoritative and cutting-edge, Plant Cell Culture Protocols,
Fourth Edition aims to serve both professionals and novices with
its guide to the most common and applicable techniques and methods
for plant tissue and cell culture.
