Müller, J.; Toev, T.; Heisters, M.; Teller, J.; Moore, K. L.; Hause, G.; Dinesh, D. C.; Bürstenbinder, K.; Abel, S. Iron-Dependent Callose Deposition Adjusts Root Meristem Maintenance to Phosphate Availability Devel Cell 33, 216–230, (2015) DOI: 10.1016/j.devcel.2015.02.007

Plant root development is informed by numerous edaphic cues. Phosphate (Pi) availability impacts the root system architecture by adjusting meristem activity. However, the sensory mechanisms monitoring external Pi status are elusive. Two functionally interacting Arabidopsis genes, LPR1 (ferroxidase) and PDR2 (P5-type ATPase), are key players in root Pi sensing, which is modified by iron (Fe) availability. We show that the LPR1-PDR2 module facilitates, upon Pi limitation, cell-specific apoplastic Fe and callose deposition in the meristem and elongation zone of primary roots. Expression of cell-wall-targeted LPR1 determines the sites of Fe accumulation as well as callose production, which interferes with symplastic communication in the stem cell niche, as demonstrated by impaired SHORT-ROOT movement. Antagonistic interactions of Pi and Fe availability control primary root growth via meristem-specific callose formation, likely triggered by LPR1-dependent redox signaling. Our results link callose-regulated cell-to-cell signaling in root meristems to the perception of an abiotic cue

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.
