Primate phylogeny: molecular evidence for a pongid clade excluding humans and a prosimian clade containing tarsiers [PDF]

open access: yes, 2009
Interpretations of molecular data by the modern evolution theory are often sharply inconsistent with paleontological results. This is to be expected since the theory is only true for microevolution and yet fossil records are mostly about macroevolution.

Loss of NR2F6 Protects from Salmonella Typhimurium Infection

open access: yesAdvanced Science, EarlyView.
Loss of nuclear receptor NR2F6 reduces tissue‐resident macrophage populations. Nr2f6‐deficient mice are protected from weight loss and bacterial load during infection with Salmonella Typhimurium. Pro‐inflammatory cytokines and iron levels are altered in infected Nr2f6‐deficient mice.

Coming to America: Multiple Origins of New World Geckos [PDF]

open access: yes, 2011
Geckos in the Western Hemisphere provide an excellent model to study faunal assembly at a continental scale. We generated a time-calibrated phylogeny, including exemplars of all New World gecko genera, to produce a biogeographic scenario for the New ...

GbSER02 Interacts With GhVOZ1 to Promote Fiber Elongation by Modulating Gibberellin Synthesis in Cotton

open access: yesAdvanced Science, EarlyView.
GbSER02 with a single base change (SNP517G) encodes normal serpin protein and interacts with transcription factor VOZ1 to alleviate the repression of VOZ1 on GA3ox1 and promote GA3 biosynthesis. Further, GA3 induces the expression of cell wall loosening‐related genes and decreases flavonoid content, ultimately facilitating fiber cell elongation in ...

A phylogeny of Setaria (Poaceae, Panicoideae, Paniceae) and related genera based on the chloroplast gene ndhF [PDF]

open access: yes, 2009
The genus Setaria is the largest genus in the so-called bristle clade, a monophyletic group of panicoid grasses distinguished by the presence of sterile branches, or bristles, in their inflorescences.

Pectin Metabolism Influences Phloem Architecture and Flowering Time in Arabidopsis Thaliana

open access: yesAdvanced Science, EarlyView.
Cell wall remodeling mediated by changes in pectic homogalacturonan, including its methyl‐esterification status and degradation, shapes wall architecture. This study finds that pectin metabolism dynamically modulates wall properties and triggers auxin responses, which influence phloem morphogenesis and function, mediating the long‐distance transport of

Subgenome Partitioning and Polyploid Genome Evolution in the Loach Family Botiidae (Order Cypriniformes)

open access: yesAdvanced Science, EarlyView.
This study investigates subgenome evolution and polyploidy in Cypriniformes fish, revealing complex phylogenetic relationships and genomic dynamics. By applying advanced subgenome partitioning methods, it uncovers novel insights into transposon activity and gene fractionation.

Complex evolutionary dynamics of massively expanded chemosensory receptor families in an extreme generalist chelicerate herbivore [PDF]

open access: yes, 2016
While mechanisms to detoxify plant produced, anti-herbivore compounds have been associated with plant host use by herbivores, less is known about the role of chemosensory perception in their life histories.

Manipulating Unisexual–Sexual Reproduction Transition to Engineer Genome‐Reconstructed Polyploids

open access: yesAdvanced Science, EarlyView.
This study developed an efficient approach to generate genome‐reconstructed polyploids involving unisexual gynogenetic Carassius gibelio, sexual C. auratus, and sexual C. cuvieri. The selected superior clone inherited gynogenesis ability of C. gibelio and herpesvirus resistance of wild C.

Species Limits and Phylogeography of North American Cricket Frogs (Acris: Hylidae) [PDF]

open access: yes, 2008
Cricket frogs are widely distributed across the eastern United States and two species, the northern cricket frog (Acris crepitans) and the southern cricket frog (A. gryllus) are currently recognized. We generated a phylogenetic hypothesis for Acris using
