This book describes the mechanisms of nutrient taken up by plants
at the biochemical and molecular level. This is a new concept
developed over the past 30 years, primarily due to use of modern
technology developed in biotechnological research, instrumentation,
modern computation facilities, bioinformatics, the large volumes of
information generated by use of various 'omics' and of course the
dedicated hard work of a large number of researchers. Recent
research indicates that nutrient uptake, its transport and
redistribution in plants are under genetic control. There are
groups of genes for each nutrient that encode transporter proteins
whose functions are to acquire the specific nutrient from the soil
and transport it across the plasma membrane of the root hair cells
for use in plant metabolism. Deficiency or sufficiency of a plant
nutrient induces different groups of genes to produce m-RNA
transcripts for translation of transporter proteins. A large number
of metabolic enzymes are up or down regulated in response to
deficiency of plant nutrients. Morphological and metabolic
adaptations in order to better acquire nutrients and use them
frugally when nutrients are scarce in the growth medium can be
observed in plants. Heavy metals, which are toxic to plants, induce
different sets of defence mechanisms. In 20 chapters, the book
describes plants' uptake mechanisms for all the major, secondary
and micronutrients, beneficial elements and heavy metals.
References to research work quoted in the text are updated up to
2014 and included at the end of each chapter. Biotechnological
approaches to improving nutrient use efficiency are discussed
wherever such information is available. The structure and functions
of transporter proteins involved in the uptake of nutrients are
discussed. Additional information on some of the specific topics is
provided in text boxes or as separate sections within the chapters.
Lastly, the terminology used has been explained as far as possible
in the text, mostly within parentheses.
