(Ebook) Rhizobiology: Molecular Physiology of Plant Roots by Soumya Mukherjee, František Baluška ISBN 9783030849849, 3030849848

This book discusses the recent advancements in the role of various biomolecules in regulating root growth and development. Rhizobiology is a dynamic subdiscipline of plant science which collates investigations from various aspects like physiology, biochemistry, genetic analysis and plant–microbe interactions. In this context, it is worth mentioning that the physiology and molecular mechanisms of root development have undergone significant advancements in the last couple of decades. Apart from the already known conventional phytohormones (IAA, GA, cytokinin, ethylene and ABA), certain novel biomolecules have been considered as potential growth regulators or hormones regulating plant growth and development. Nitric oxide, carbon monoxide and hydrogen sulphide have emerged as three potential gaseous signaling molecules in plants. Serotonin, melatonin, dopamine, GABA and acetylcholine are some of the important neurotransmitters capable of modulating root development and signaling. Jasmonates, brassinosteroids, polyamines and strigolactones have also been reported to possess plethora of effects in regulating the physiology of root growth. Root phenotyping and plasticity analysis with respect to the specific functional mutants of each biomolecule shall provide substantial information on the molecular pathways of root signaling. In this context, special emphasis shall provide insights on the tolerance and modulatory mechanisms of root physiology in response to light burst, ROS generation, agravitrophic response, abiotic stress and biotic interactions. Thus, the collation of recent developments from various biomolecules shall summarize our current understandings of root physiology. Future investigations on the characterization of receptors for new biomolecules and deciphering complex signaling pathways and cross talk mechanisms shall remain as a priority.
