Plant parasitic nematodes are costly burdens of crop production,
causing an estimated US$80 - 118 billion per year in damage to
crops. They are associated with nearly every important agricultural
crop, and are a significant constraint on global food security.
Regulations on the use of chemical pesticides have resulted in
growing interest in alternative methods of nematode control. Future
changes in climate, cropping systems, food habits, as well as
social and environmental factors also affect the options for
nematode control. Taking a systematic crop by crop approach, this
book: Outlines the economic importance of specific plant parasitic
nematode problems on the major food and industrial crops. Presents
the state-of-the-art management strategies that have been developed
to reduce specific nematode impacts, and outlines their
limitations. Contains case studies to illustrate impact in the
field. Aims to anticipate future changes in nematode disease
pressure that might develop as a result of climate change, and new
cropping systems.
This book provides a comprehensive introduction and review of
state-of-the-art biotechnological tools in enhancement of bioactive
compounds in medicinal and aromatic plants. Plant bioactive
compounds are plant-based natural products that display a variety
of pharmacological applications. These bioactive compounds are
important as medicines, pigments, flavorings and drugs because most
of the pharmaceutical industries are highly dependent on medicinal
plants and their extraction. The book introduces a systematic
overview of state-of-the-art biotechnological techniques such as
Omics, Crisper /Cas9 and RNAi to enhance the plant bioactive
contents as well as enlists various in vitro techniques, hairy root
culture and transgenic technology to enhance plant bioactive
contents using plant tissue culture approaches. The book also
provides an overview of the role of induced mutation, biotic and
abiotic stress to increase the bioactive contents in plants and
discusses the significant role of endophytes to enhance the
contents of plant bioactive compound. The book also opens
discussions related to standard operating procedures using
hydroponics system of cultivation for significant enhancement of
bioactive compound(s) and much more. This book serves as an
excellent reference book for the researchers working in the field
of plant secondary metabolites and pharmaceutical industries at
global level.

An eight-year-old orphan is living off the streets and through the
kindness of strangers. His home is a shack in the slums of
Kinshasa. Harbouring deep feelings, and wants of a better life. He
plans his escape which he must accomplish against all the odds.
Soon he gets the opportunity, a charming stranger presents an
opportunity to him. He makes his escape but does not get what was
promised. For he has now found his way, not in a family home, but a
coltan mine. The kind stranger was a child trafficker who would
lure his victims with outrageous promises of a better life. Over
the years to come, the orphan despite being so young, would work as
hard as any adult. This served however, to make him stronger. He
would learn about life, and about what is tearing his country
apart. Into the Abyss tells the story of an orphan, born in the
slums of Kinshasa, who escapes only to find himself trapped in a
coltan mine. But where this life would take him, would be
anyone’s guess. Set in The Congo, this is a book about conflict,
poverty, dreams, hope, and generosity.

Disease resistance is one of the major factors that can be improved
to sustain yield potential in cultivated crops. This book looks at
disease resistance in wheat, concentrating on all the economically
important diseases their economic impact and geographical spread,
breeding for resistance, pathogen variability, resistance
mechanisms and recent advances made on resistance genes. Newer
strategies for identifying resistance genes and identify resistance
mechanisms are discussed, including cloning, gene transfer and the
use of genetically modified plants. "
Information on both extent and pattern of variability as well as
interrelationship, among characters is very essential in any crop
improvement. This work showed that there were significant
differences among the genotypes for all characters except leaf- let
index which was non significant, indicating the existence of
adequate genetic variability. In conclusion, future breeding
efforts should aim at exploiting the genetic variability available
in the test genotypes for improvement of tuber yield. The present
work considered, however, only a limited number of characters owing
to the limitation of resources and facilities. Therefore, it is the
subject of future investigations to evaluate the extent and pattern
of genetic variation by considering other additional characters of
crucial importance in selection of superior genotypes. Potential
genetic resources for such characters as resistance or tolerance to
biotic and abiotic stresses when considered along with the results
of the present study could vastly improve the elucidation of
association of characters and improve selection efficiency.
