Molecular Life of Plants

The Molecular Life of Plants offers students with an inventive, unified approach to plant science. It looks at the procedures and mechanisms that underline each stage of plant life and describes the intricate network of cellular, molecular, biochemical and physiological events through which plants make life on land possible. The text is organized into ten chapters. The aim of first chapter is to give an overview on mono-ubiquitination of nuclear annexin A1 and mutagenesis. In second chapter molecular mechanism of action of antimutagens have been described. DNA is a dynamic molecule that is constantly damaged and repaired. Major sources of DNA lesions are physical and chemical agents DNA, incorporation of foreign or damaged nucleotides, etc. As a response to DNA damage, essentially all organisms have developed elaborate DNA repair mechanisms to preserve the integrity of their genetic material: reversion, excision or tolerance of lesion. These mechanisms are largely conserved among prokaryotes, including human cells. Third chapter reviews about the plants colonizing metal-contaminated soils classified as resistant and have adapted to this stressed environment. Fourth chapter involves the extraction of the plant material with EtOAc and then alkalinization of the plant residue and successive extraction with EtOAc and MeOH. Fifth chapter reviews in a larger context and to ultimately suggest future avenues in the study of the evolution of insular biota we explore how molecular evidence on the Corsica-Sardinia system relates to comparative phylogeographies available for other insular systems. In chapter six, several non-traditional plants are being studied with the aim to isolate fibres from plant leaves or stems. A review of different conventional and non-conventional fibres is presented. the importance of plants in the remediation of heavy metal polluted soil is discussed in seventh chapter. A review of the current knowledge on metal resistance mechanisms, as well as the potential genes and their role in metal homeostasis in plants is examined. Finally, the coping mechanisms used by plants growing under metal contamination is discussed. In eighth chapter, we evaluate the spread of resistance when a two-toxin Bt crop is planted alone after a one -toxin Btcrop. Chapter nine focuses on current achievements in several important topics concerning satRNAs and satellite viruses, namely replication mechanisms, pathogenicity, and molecular evolution. By understanding satRNAs and satellite viruses, we may gain further knowledge of the molecular biology of their cognate helper viruses and host plants. In chapter ten, we summarize rice root responses to Fe deficiency, which consist of Fe uptake from the rhizosphere, Fe translocation to the xylem and phloem, and their expressional modulation by positive and negative regulators.
