Early June 2009 papers

Some interest papers.

Snapshots of the cell surface, Allison Doerr, Nature Methods 6:401.
Researchers develop an approach to selectively isolate and profile cell-surface proteins by targeting the glycopeptides, a strategy that could be used to generate an atlas of cell-surface protein 'barcodes'.

BIOSENSORS: Nature's pH meter, Wayne Peng, Nature Methods 6:404 (2009).
A new pH nanosensor changes color in acidic cell compartments by forming an unusual four-stranded DNA structure.

TACLing rare genetic variants, Nicole Rusk, Nature Methods 6:406.
By combining methods for selective genome capture, allele enrichment and array resequencing, researchers create a pipeline for high-throughput variant detection.

A review on transgenic approaches to accelerate breeding of woody plants, H. Flachowsky, M.-V. Hanke, A. Peil, S. H. Strauss, M. Fladung, Plant Breeding 128(3):217 - 226.

Local auxin biosynthesis modulates gradient-directed planar polarity in Arabidopsis, Yoshihisa Ikeda, Shuzhen Men, Urs Fischer, Anna N. Stepanova, Jose M. Alonso, Karin Ljung and Markus Grebe, Nature Cell Biology 11:731 - 738.
Arabidopsis root-hair position and orientation in epithelial cells is directed by an auxin gradient maximum at the root tip. The Raf-like kinase CTR1 negatively regulates local auxin biosynthesis in the root to determine root hair position.

Genomic dissection of drought resistance in durum wheat × wild emmer wheat recombinant inbreed line population, ZVI PELEG, TZION FAHIMA, TAMAR KRUGMAN, SHAHAL ABBO, DAN YAKIR, ABRAHAM B. KOROL, YEHOSHUA SARANGA, Plant, Cell & Environment 32(7):758 - 779.

ETR1-Specific Mutations Distinguish ETR1 from Other Arabidopsis Ethylene Receptors as Revealed by Genetic Interaction with RTE1, Maximo Rivarola, Christopher A. McClellan, Josephine S. Resnick, and Caren Chang, Plant Physiol. 150:547-551.

Chang, Ireneusz Slesak, Lucia Jorda, Alexey Sotnikov, Michael Melzer, Zbigniew Miszalski, Philip M. Mullineaux, Jane E. Parker, Barbara Karpinska, and Stanislaw Karpinski, Plant Physiol. 150:670-683.

Anatomical and Transcriptomic Studies of the Coleorhiza Reveal the Importance of This Tissue in Regulating Dormancy in Barley, Jose M. Barrero, Mark J. Talbot, Rosemary G. White, John V. Jacobsen, and Frank Gubler, Plant Physiol. 150:1006-1021.

Antisense Down-Regulation of the FaPG1 Gene Reveals an Unexpected Central Role for Polygalacturonase in Strawberry Fruit Softening, Miguel A. Quesada, Rosario Blanco-Portales, Sara Pose, Juan A.

Role of Temperature Stress on Chloroplast Biogenesis and Protein Import in Pea, Siddhartha Dutta, Sasmita Mohanty, and Baishnab C. Tripathy, Plant Physiol. 150:1050-1061.

Regulation of a Chemical Defense against Herbivory Produced by Symbiotic Fungi in Grass Plants, Dong-Xiu Zhang, Padmaja Nagabhyru, and Christopher L. Schardl, Plant Physiol. 150:1072-1082.

The Wound-, Pathogen-, and Ultraviolet B-Responsive MYB134 Gene Encodes an R2R3 MYB Transcription Factor That Regulates Proanthocyanidin Synthesis in Poplar, Robin D. Mellway, Lan T. Tran, Michael B. Prouse, Malcolm M. Campbell, and C. Peter Constabel, Plant Physiol. 150:924-941.

Water Flea Boasts Whopper Gene Count, Science 324(5932):1252.
Daphnia pulex, a crustacean common in lakes and ponds around the world, is no bigger than the letters on this page, but its genome contains more genes than some much larger organisms have, scientists reported at the Biology of Genomes meeting.

Some RNA May Play Key Role in Repressing Genes, Slowing Cancer, Science 324(5932):1252 - 1253.
Just as junk DNA proved to be more than junk, at least some non-protein-coding RNA translates into meaningful molecules that may play key roles in turning genes on and off, scientists reported at the Biology of Genomes meeting.

The Bug and the Bacterium: Interdependent Genomes, Science 324(5932):1253.
The newly sequenced DNA of the pea aphid, a common pest of legume crops, reflects a long history of give-and-take between the genomes of the bug and a tiny bacterium called Buchnera aphidicola, scientists reported at the Biology of Genomes meeting.

A Story of Symbiosis, Leigh Krietsch Boerner, Science 324(5932):1270.
The adventures of the Beans in Marder's fanciful world reflect aspects of ecology, culture, invention, and the scientific method.

Fusarium oxysporum hijacks COI1-mediated jasmonate signaling to promote disease development in Arabidopsis, Louise F. Thatcher, John M. Manners, Kemal Kazan, The Plant Journal 58(6):927 - 939.
