A synthesis of well logs was carried out and drilling mud weight data were analyzed to figure out anomalous high fluid pressure within the Triassic evaporitic cap rock (the Dashtak formation) and study its impact on the geometry of anticlinal traps in the gas rich Gavbandi province located in the southeast part of the Zagros Mountains. The results indicated that the location of anticlinal traps...

In gametophytic cells (prothalli) of the fern Adiantum capillus-veneris, nuclei as well as chloroplasts change their position according to light conditions. Nuclei reside on anticlinal walls in darkness and move to periclinal or anticlinal walls under weak or strong light conditions, respectively. Here we reveal that red light-induced nuclear movement is mediated by neochrome1 (neo1), blue ligh...

The driving forces behind gas flow and migration, as well the associated gas–water distribution patterns in tight reservoirs, are not only closely related to formation mechanisms of “sweet spots”, but also serve crucial geological foundations for development efficient modes optimal placement. In this work, three methods, namely, critical column height driven by buoyancy, pore throat radius atti...

In epidermal and mesophyll cells of Arabidopsis (Arabidopsis thaliana) leaves, nuclei become relocated in response to strong blue light. We previously reported that nuclear positions both in darkness and in strong blue light are regulated by the blue light receptor phototropin2 in mesophyll cells. Here, we investigate the involvement of phototropin and the actin cytoskeleton in nuclear position...

The organization of the microfilaments in epidermal cells of Vallisneria leaves was investigated with respect to the induction of cytoplasmic streaming (secondary streaming). In many of the epidermal cells, cytoplasm exhibited rotational streaming along the anticlinal wall of the cell after exposure around the anticlinal wall. The bundles were arrayed in parallel to the streaming direction. The...

Differentiation of plant cells is regulated by position-dependent mechanisms rather than lineage. The maize Extra cell layers1 (Xcl1) mutation causes oblique, periclinal divisions to occur in the protoderm layer. These protodermal periclinal divisions occur at the expense of normal anticlinal divisions and cause the production of extra cell layers with epidermal characteristics, indicating that...
