Dual control by a single gene of secondary sexual characters and mating preferences in medaka Shoji Fukamachi, Masato Kinoshita, Kouichi Aizawa, Shoji Oda, Axel Meyer, Hiroshi Mitani BMC Biology 2009, 7:64 (29 September 2009) A somatolactin mutation in medaka fish that reduces orange pigmentation makes them unattractive to all medaka but those carrying the mutation, suggesting that a single mutation can trigger assortative mating leading to speciation.

c-Myc affects mRNA translation, cell proliferation and progenitor cell function in the mammary gland Tina Stoelzle, Patrick Schwarb, Andreas Trumpp, Nancy E Hynes BMC Biology 2009, 7:63 (28 September 2009) c-myc knockout mice have slower alveolar cell proliferation in the mammary gland during pregnancy and less efficient translation of mRNAs involved in milk production, showing c-Myc to be important for pregnancy and lactation in mice.

Gregory R Leong, Karen R Goulding, Nancy Amin, Helena E Richardson, Anthony M Brumby BMC Biology 2009, 7:62 (24 September 2009) Scribble, a cell polarity regulator in Drosophila, represses tumorigenesis by inhibiting atypical protein kinase C and Jun N-terminal kinase-dependent pathways, and this might be relevant for how human Scrib restrains oncogene-mediated transformation.

Alejandro Zúñiga, Christian Hödar, Patricia Hanna, Freddy Ibáñez, Pablo Moreno, Rodrigo Pulgar, Luis Pastenes, Mauricio González, Verónica Cambiazo BMC Biology 2009, 7:61 (22 September 2009) Many previously uncharacterized genes uncovered by a subtractive hybridization analysis of early Drosophila development are spatiotemporally regulated during embryogenesis, including genes encoding a set of secreted and transmembrane proteins.

Genetic determinants of mate recognition in Terry W Snell, Tonya L Shearer, Hilary A Smith, Julia Kubanek, Kristin E Gribble, David B Mark Welch BMC Biology 2009, 7:60 (9 September 2009) The rotifer mate recognition pheromone gene has been isolated from female animals and has been shown to affect male mating behavior, which should prove valuable in studying the evolution and speciation of these tiny aquatic animals.

Receptor oligomerization and beyond: a case study in bone morphogenetic proteins Kai Heinecke, Axel Seher, Werner Schmitz, Thomas D Mueller, Walter Sebald, Joachim Nickel BMC Biology 2009, 7:59 (7 September 2009) At low concentrations, bone morphogenetic proteins can bind preformed receptors to give rapid transient signals, while at high concentrations, they bind single receptor chains then recruit others to generate sustained and diverse signals through different oligomeric complexes.

Christian Seibel, Gabriela Gremel, Roberto do Nascimento Silva, André Schuster, Christian P Kubicek, Monika Schmoll BMC Biology 2009, 7:58 (3 September 2009) The G-protein signaling subunit GNA1 modulates growth of the fungus Trichoderma reesei, responding to environmental cues such as carbon source and light, and altering the regulation of cellulase expression.

Agustín Estrada-Peña, Victoria Naranjo, Karina Acevedo-Whitehouse, Atilio J Mangold, Katherine M Kocan, José de la Fuente BMC Biology 2009, 7:57 (1 September 2009) Sequence divergence of the major surface protein MSP1a of the intracellular bacterial parasite Anaplasma indicates different evolutionary pressures in different ecoregions, and a role for environmental factors that affect the tick vector.
