From filaments to function: The role of the plant actin cytoskeleton in pathogen perception,signaling and immunity

引用

Journal of Integrative Plant biology 2016年第4期58卷 299-311页

作者： katie Porter brad Day Graduate Program in Cell and Molecular biology Michigan State University Department of Plant Soil and Microbial Sciences Michigan State University Graduate Program in Genetics Michigan State University

The eukaryotic actin cytoskeleton is required for numerous cellular processes, including cell shape, development and movement, gene expression and signal transduction, and response to biotic and abiotic stress. In recent years,research in both plants and animal systems have described a function for actin as the ideal surveillance platform, linking the function and activity of primary physiological processes to the immune system. In this review, we will highlight recent advances that have defined the regulation and breadth of function of the actin cytoskeleton as a network required for defense signaling following pathogen infection. Coupled with an overview of recent work demonstrating specific targeting of the plant actin cytoskeleton by a diversity of pathogens,including bacteria, fungi and viruses, we will highlight the importance of actin as a key signaling hub in plants, one that mediates surveillance of cellular homeostasis and the activation of specific signaling responses following pathogen perception. b4 ased on the studies highlighted herein, we propose a working model that posits changes in actin filament organization is in and of itself a highly specific signal, which induces, regulates and physically directs stimulus-specific signaling processes, most importantly, those associated with response to pathogens.

Age at reproductive maturity and effect of age and time of day on sex attraction in the potato psyllid bactericera cockerelli

引用

Insect Science 2012年第5期19卷 585-594页

作者： Christelle Guedot David R. horton Peter J. Landolt U.S. Department of Agriculture Agricultural Research Service 5230 Konnowac Pass Road Wapato WA 98951 USA

The potato psyllid, baetericera （= Paratrioza） cockerelli （gulc）（Hemiptera： Triozidae）, is a major pest of potato. Studies were conducted to determine the age at which both males and females reach reproductive maturity and the effect of age and time of day on sex attraction. Adult b. cockerelli reach reproductive maturity within 48 h post-eclosion, with females being mature on the day of eclosion and males at 1 day post-eclosion. Oviposition generally began 2 days after mating but was delayed when females mated within 2 days post-eclosion. In laboratory olfactometer assays, the age of females used as odor sources and the age of males assayed to these odors did not affect sex attraction, with both younger （1-4-day-old） and older （8-10-day-old） males being attracted to females, regardless of female age （1-4-day-old or 8-10-day-old）. Males assayed to live females at different times during the photophase （between 8：00 and 20：00 hours） were attracted to females between 11：00 and 17：00 hours, showing a temporal periodicity in sex attraction with b. cockerelli at least during the photophase.

为了对比夹层位置和土壤质地变化对层状土入渗特征的影响,选用2种土壤、设置3个夹层位置进行了积水入渗试验.结果表明:在夹层位置为距土表5～10,10～15和20～25 cm这3种情况下,湿润锋到达土层界面的时间和相应的累积入渗量随夹层位置和夹层土壤质地的差异而有所不同.夹层的层位越靠上,湿润锋到达夹层分界线所需要的时间越短,相应的累积入渗量越小.距土表10～15 cm的夹层位置减渗效果最好;夹砂层位置越深,其对入渗率的改变程度越明显,入渗率曲线整体抬高.累积入渗量及湿润锋在水分进入夹层界面前随时间延长而非线性递增,而在水分进入层界面之后趋于线性变化,两者之间具有概化的线性关系,且其线性关系随夹层位置的变化而不同.层状土的土壤含水率分布具有不连续性,同时还受夹层土壤质地的影响.总体上,夹层位置变化对不同质地层状土的入渗有明显影响.

The Part Count Tool (PaCT) for Design Concept Selection

引用

Modern Mechanical Engineering 2011年第2期1卷 13-24页

作者： Tarang Parashar Kerry Poppa katie Grantham Lough Robert b. Stone 不详

This paper presents a part count tool that predicts the part count for a particular product concept during the conceptual design phase. The part count tool will also aid in ranking the design concepts by the criterion of number of components for a product. This tool utilizes existing automated concept generation algorithms to generate the design concepts. It extracts the available data from the Design Engineering Lab Design Repository to determine an average number of parts per component type in the repository and then calculates an average part count for new concepts. The part count tool also uses an algorithm to determine how to connect two non-compatible components through the addition of mutually compatible components. While emphasis is placed on the average parts per product in evaluating designs, the overall functional requirement of the product is also considered.
