An H+ P-ATPase on the tonoplast determines vacuolar pH and flower colour, Walter Verweij, Cornelis Spelt, Gian-Pietro Di Sansebastiano, Joop Vermeer, Lara Reale, Francesco Ferranti, Ronald Koes and Francesca Quattrocchio, Nature Cell Biology 10, 1456 - 1462 (2008).
P-ATPases in plants are typically thought to act at the plasma membrane. In contrast, PH5, a P-type H+ ATPase functions within the vacuolar membrane to control acidification during flower coloration.
Activation of TGF-b/activin signalling resets the circadian clock through rapid induction of Dec1 transcripts, Naohiro Kon, Tsuyoshi Hirota, Takeshi Kawamoto, Yukio Kato, Tadashi Tsubota and Yoshitaka Fukada, Nature Cell Biology 10, 1463 - 1469 (2008).
The circadian clock is synchronized with the environment. In mammals, besides light input mediated by Per genes, little is known about resetting mechanisms. TGF-beta and activin reset the clock by acting on the circadian gene Dec1.
Agronomy: Five crop researchers who could change the world, Emma Marris, Nature 456, 563-568 (3 December 2008).
The current crisis in worldwide food prices reinforces the need for more productive agriculture. Emma Marris meets five ambitious scientists determined to stop the world from going hungry.
Role of Plant alpha Importin Proteins in Agrobacterium-Mediated Transformation, Nancy A. Eckardt (News and Reviews Editor), The Plant Cell 20(10):2541 (Dec 2008).
Transcriptome-Wide Analysis of Uncapped mRNAs in Arabidopsis Reveals Regulation of mRNA Degradation, Yuling Jiao, José Luis Riechmann, and Elliot M. Meyerowitz, The Plant Cell 20(10):2571-2585 (Dec 2008).
Histone H2B Monoubiquitination in the Chromatin of FLOWERING LOCUS C Regulates Flowering Time in Arabidopsis, Ying Cao, Yan Dai, Sujuan Cui and Ligeng Ma, The Plant Cell 20(10):2586-2602 (Dec 2008).
OCEANS: Elements and Evolution, Ariel D. Anbar, Science 322(5907):1481 - 1483 (5 December 2008).
Changes in elemental abundances in Earth's oceans on geological time scales are intimately linked to evolutionary processes.
CELL SIGNALING: Fat Stress and Liver Resistance, Wataru Ogawa and Masato Kasuga, Science 322(5907):1483 - 1484 (5 December 2008).
Communication among immune and fat cells in adipose tissue and liver hepatocytes underlies the pathogenesis of obesity-related insulin resistance.
Photoexcited CRY2 Interacts with CIB1 to Regulate Transcription and Floral Initiation in Arabidopsis, Hongtao Liu, Xuhong Yu, Kunwu Li, John Klejnot, Hongyun Yang, Dominique Lisiero, Chentao Lin, Science 322(5907):1535 - 1539 (5 December 2008).
Cryptochromes (CRY) are photolyase-like blue-light receptors that mediate light responses in plants and animals. How plant cryptochromes act in response to blue light is not well understood.
AGAMOUS-LIKE24 and SHORT VEGETATIVE PHASE determine floral meristem identity in Arabidopsis, Veronica Gregis, Alice Sessa, Lucia Colombo, Martin M. Kater, The Plant Journal 56(6):891 - 902 (2008).
