A calcineurin B-like protein-interacting protein kinases （CIPK） gene was cloned （EU 424058） from a thermo-sensitive genic self-incompatibility （TSGI） line, HE97, in maize, which was selected for suppression subtractive hybridization （SSH） library of the self-incompatible and self-compatible silks of the TSGI line under different temperatures. The full-length cDNA of the candidate CIPK-like gene consisted of 1 918 nucleotides and contained a 1 332-bp open reading frame in maize. Real-time PCR indicated that the candidate CIPK-like gene was highly expressed in the self-incompatible pollen of the TGSI line, and promoted elevated levels of calcium （Ca2＋）. High Ca2＋ concentrations in the pollen strongly inhibit pollen tube formation in silk of the same plant, thus inducing self-incompatibility （SI） under high temperature. These results implied that the CIPKs-like gene would play an important role in the regulation of HE97 characteristics under different temperatures, perhaps acting as a secondary messenger in the expression of SI in the TGSI line in maize.

In petroleum industries and seawater environment,the corrosion phenomena have become particularly harsh,especially for pipelines and pressure vessels that transport or contain media that contain quantities of corrosive medium,such as sulfides,chlorides,and carbon dioxide,*** occurrence of corrosion failure will not only reduce the mechanical properties of materials.

Landscape boundaries are always indicated by the vegetation boundaries. As an ecotone between closed forest and treeline, alpine timberline may respond to global climate changes sensitively. The stability of timberline and treeline depend not only on climate change, but also on the interaction of both sides of the ecosystems. Three natural boundaries existing in the timberline transitional zone are recognized: (1) timberline (upper limit of closed forest zone); (2) treeline (upper limit of tree islands zone); (3) tree species line (upper limit of individual tree growth). Paleobotanical and sedimentary evidences suggest that there were several times of climate fluctuation during the Holocene period in this area. The timberline of Taibai Mountain must have moved for four times on the millennium scale. Being a stochastic oscillation boundary, treeline appears in a semi stable condition on the century scale. The tree species line is even more unstable, which appears in an unstable status on the decades scale. The comparison of the stability within several landscape boundaries, shed light on the sensibility of these communities to various perturbation and environmental heterogeneity, i.e., herb community is the most sensitive one, which is followed by shrubs, and forest is the most stable one. Trees and shrubs can adapt to rocky and poor soils. On the contrary, alpine herbs are able to adapt to wetter and cooler soils. Finally, under a scenario of a temperature of 1.5 4.5℃ increase, the present timberline will be relatively stable but treeline and tree species line will move upward.

＜正＞Water is ubiquitous. But we don’t know the half of it. The existence of nanobubbles at the interface makes the behavior of water more elusive. And the accumulation of gas at the nanometer scale at the water/solid interface has evoked an upwelling of re-considerations on the traditional understanding of many classical processes such as fast folding of proteins,

在单向运营航道疏浚拓宽施工中,抓斗船需在过往船舶通过时,提前起锚远离航道一侧进行避让,如频繁避让会严重降低抓斗船的生产效率。为此通过研发锚漂快速收回装置,结合抓斗船在边坡施工过程中的特点和海水流向的不同,在保证船舶安全及稳性的前提下,采取抛设单侧一字锚、不等距锚、等距抛锚等工艺,降低避让对施工效率的影响。经过现场实践证明,该施工工艺可有效提高抓斗船在该种工况下的施工效率。
