Wasternack, C.; Hause, B. Jasmonates: biosynthesis, perception, signal transduction and action in plant stress response, growth and development. An update to the 2007 review in <span>Annals of Botany</span> Annals of Botany 111, 1021-1058, (2013) DOI: 10.1093/aob/mct067

Background: Jasmonates are important regulators in plant responses to biotic and abiotic stresses as well as indevelopment. Synthesized from lipid-constituents, the initially formed jasmonic acid is converted to differentmetabolites including the conjugate with isoleucine. Important new components of jasmonate signalling includingits receptor were identified, providing deeper insight into the role of jasmonate signalling pathways in stressresponses and development.Scope: The present review is an update of the review on jasmonates published in this journal in 2007. New dataof the last five years are described with emphasis on metabolites of jasmonates, on jasmonate perception andsignalling, on cross-talk to other plant hormones and on jasmonate signalling in response to herbivores and pathogens,in symbiotic interactions, in flower development, in root growth and in light perception.Conclusions: The last few years have seen breakthroughs in the identification of JASMONATE ZIM DOMAIN(JAZ) proteins and their interactors such as transcription factors and co-repressors, and the crystallization of thejasmonate receptor as well as of the enzyme conjugating jasmonate to amino acids. Now, the complex nature ofnetworks of jasmonate signalling in stress responses and development including hormone cross-talk can beaddressed.

Abel, S. Phosphate sensing in root development Curr Opin Plant Biol 14, 303-309, (2011) DOI: 10.1016/j.pbi.2011.04.007

Phosphate (Pi) and its anhydrides constitute major nodes in metabolism. Thus, plant performance depends directly on Pi nutrition. Inadequate Pi availability in the rhizosphere is a common challenge to plants, which activate metabolic and developmental responses to maximize Pi usage and acquisition. The sensory mechanisms that monitor environmental Pi and transmit the nutritional signal to adjust root development have increasingly come into focus. Recent transcriptomic analyses and genetic approaches have highlighted complex antagonistic interactions between external Pi and Fe bioavailability and have implicated the stem cell niche as a target of Pi sensing to regulate root meristem activity.

Quint, M.; Gray, W.M. Auxin signaling Curr Opin Plant Biol 9, 448-453, (2006) DOI: 10.1016/j.pbi.2006.07.006

Auxin regulates a host of plant developmental and physiological processes, including embryogenesis, vascular differentiation, organogenesis, tropic growth, and root and shoot architecture. Genetic and biochemical studies carried out over the past decade have revealed that much of this regulation involves the SCFTIR1/AFB-mediated proteolysis of the Aux/IAA family of transcriptional regulators. With the recent finding that the TRANSPORT INHIBITOR RESPONSE1 (TIR1)/AUXIN SIGNALING F-BOX (AFB) proteins also function as auxin receptors, a potentially complete, and surprisingly simple, signaling pathway from perception to transcriptional response is now before us. However, understanding how this seemingly simple pathway controls the myriad of specific auxin responses remains a daunting challenge, and compelling evidence exists for SCFTIR1/AFB-independent auxin signaling pathways.

A., Maniloff, J., Desselberger, U., Ball, L. A.). Elsevier, Academic Press 673-679, (2005) ISBN: 9780080575483; 9780122499517

Virus Taxonomy is a standard and comprehensive source for the classification of viruses, created by the International Committee of the Taxonomy of Viruses. The book includes eight taxonomic reports of the ICTV and provides comprehensive information on 3 taxonomic orders of viruses, 73 families, 9 subfamilies, 287 genera, and 1938 virus species. The book also features about 429 colored pictures and diagrams for more efficient learning. The text is divided into four parts, comprised of 16 chapters and presenting the following features: • Compiled data from numerous international experts about virus taxonomy and nomenclature • Organized information on over 6000 recognized viruses, illustrated with diagrams of genome organization and virus replication cycle • Data on the phylogenetic relationships among viruses of the same and different taxa • Discussion of the qualitative and quantitative relationships of virus sequences The book is a definitive reference for microbiologists, molecular biologists, research-level virologists, infectious disease specialists, and pharmaceutical researchers working on antiviral agents. Students and novices in taxonomy and nomenclature will also find this text useful.
