This book aims to describe, though in a quite light way, the social
role of plant diseases, letting the reader know the topical
importance of plant pathology, as well as the role of plant
pathologists in our society. Plant diseases caused, in the past,
significant economic losses, deaths, famine, wars, and migration.
Some of them marked the history of entire countries. One example
among many: the potato late blight in Ireland in 1845. Today plant
diseases are still the cause of deaths, often silent, in developing
countries, and relevant economic losses in the industrialized ones.
This book, written with much passion, neither wants to be a plant
pathology text. On the contrary, it wants to describe, in simple
words, often enriched by the author's personal experience, various
plant diseases that, in different times and countries, did cause
severe losses and damages. Besides the so-called "historical plant
diseases", in the process of writing this book, she wanted to
describe also some diseases that, though not causing famine or
billions of losses, because of their peculiarity, might be of
interest for the readers. Thus, this book has not been conceived
and written for experts, but for a broader audience, of different
ages, willing to learn more about plant health and to understand
the reasons why so many people in the past and nowadays choose to
be plant pathologists. This is because plants produce most of the
food that we consume, that we expect to be healthy and safe, and
because plants make the world beautiful. The title "Spores" is
evocative of the reproduction mean of fungi. Spores are small,
light structures, often moving fast. The chapters of this book are
short and concise. Just like spores!
This book will present information on Pantanal vegetation including
an updated checklist of flora, useful plants, ecological aspects
and some topics never published for this region, such as lichens.
It aims to be a reference for researchers, graduate and
undergraduate students as well as stakeholders and decision makers
interested in the flora and vegetation of one of the world's
largest tropical wetlands.
Of the global population of more than 7 billion people, some 800
million do not have enough to eat today. By 2050, the population is
expected to exceed 9 billion. It has been estimated that some 15%
of food production is lost to plant diseases; in developing
countries losses may be much higher. Historically, plant diseases
have had catastrophic impact on food production. For example:
potato blight caused the Irish famine in 1845; brown spot of rice
caused the Great Bengal Famine of 1943; southern corn leaf blight
caused a devastating epidemic on the US corn crop in 1970. Food
security is threatened by an ongoing sequence of plant diseases,
some persistent for decades or centuries, others more
opportunistic. Wheat blast and banana xanthomonas wilt are two
contrasting examples of many that currently threaten food
production. Other emerging diseases will follow. The proposed title
aims to provide a synthesis of expert knowledge to address this
central challenge to food security for the 21st century. Chapters

Abiotic stress has a detrimental impact on the living organisms in
a specific environment and constitutes a major constraint to global
agricultural production. The adverse environmental conditions that
plants encounter during their life cycle not only disturb their
metabolic reactions, but also hamper their growth and development
on cellular and whole plant levels. These conditions are of great
concern, particularly for those countries whose economies primarily
rely on agriculture. Under abiotic stresses, plants amalgamate
multiple external stress cues to bring about a coordinated response
and establish mechanisms to mitigate such stresses by triggering a
cascade of events leading to enhanced tolerance.
"Physiological Mechanisms and Adaptation Strategies in Plants
under Changing Environment," "Volume 2" displays the ways by which
plants utilize and integrate many common signals and subsequent
pathways to cope with less favourable environmental conditions."
"The book also describes the use of contemporary tools for the
improvement of plants under such stressed environments. Concise yet
comprehensive, "Physiological Mechanisms and Adaptation Strategies
in Plants under Changing Environment," "Volume 2" is an
indispensable resource for researchers, students, environmentalists
and many others in this burgeoning area of research."
This volume is a monograph of the genus Diplusodon (Lythraceae),
written by the world authority on this plant group. Diplusodon is a
monophyletic genus of shrubs and subshrubs, with showy, 6-merous,
actinomorphic flowers, and floral tubes on which the sepals
alternate with conspicuous epicalyx segments. The capsular fruit
contains winged seeds and, uniquely for the family, is divided by a
bipartite placenta with two semi-lunate septa. Diplusodon is the
second largest genus in the Lythraceae and occurs mostly in the
Cerrado Biome, the floristically diverse savannah that covers more
than two million km2 of the Central Brazilian Plateau, extending
west into Bolivia, south to Paraguay and east to the Caatinga. A
total of 104 species and eight varieties are recognized in the
genus, for which 46 lectotypes, one neotype, one new status and one
new combination are designated, nine new species are described, and
15 taxa are placed in synonymy. New information on floral and
vegetative morphology, pollen, cytology, chemistry, floral biology,
and habitat are provided for the genus. In addition, keys to the
species are accompanied by descriptions, illustrations,
distribution maps, and assignment of conservation status.
