Modeling Floral Induction in the Narrow-Leafed Lupin Under Different Environmental Conditions.

Flowering is initiated in response to environmental cues, with the photoperiod and ambient temperature being the main ones. The regulatory pathways underlying floral transition are well studied in but remain largely unknown in legumes. Here, we first applied an in silico approach to infer the regulatory inputs of four -like genes of the narrow-leafed lupin .

The RNA-Binding Protein SBR (Dm NXF1) Is Required for the Constitution of Medulla Boundaries in Optic Lobes.

() is an orthologue of the () genes in different The known function of genes is the export of various mRNAs from the nucleus to the cytoplasm. The cytoplasmic localization of the SBR protein indicates that the nuclear export function is not the only function of this gene in RNA-binding protein SBR enriches the nucleus and cytoplasm of specific neurons and glial cells. In mutant males, the disturbance of medulla boundaries correlates with the defects of photoreceptor axons pathfinding, axon bundle individualization, and developmental neurodegeneration.

Food sources for the Ediacara biota communities.

The Ediacara biota represents the first complex macroscopic organisms in the geological record, foreshadowing the radiation of eumetazoan animals in the Cambrian explosion. However, little is known about the contingencies that lead to their emergence, including the possible roles of nutrient availability and the quality of food sources. Here we present information on primary producers in the Ediacaran based on biomarker molecules that were extracted from sediments hosting Ediacaran macrofossils.

Dynamic maternal gradients and morphogenetic networks in Drosophila early embryo.

Here, we review the latest publications on dynamics and interpretation of morphogen gradients in Drosophila early embryo. The instructive cues provided by these gradients are further interpreted by target genes to enable correct cell fate specification. Moreover, recent studies point on the dynamic and active input from gradients themselves.

RNA-binding proteins of the NXF (nuclear export factor) family and their connection with the cytoskeleton.

The mutual relationship between mRNA and the cytoskeleton can be seen from two points of view. On the one hand, the cytoskeleton is necessary for mRNA trafficking and anchoring to subcellular domains. On the other hand, cytoskeletal growth and rearrangement require the translation of mRNAs that are connected to the cytoskeleton.
