Animals are increasingly faced with human?induced stressors that vary in space and time, thus we can expect populati on-level diverge nee in behaviors that help animals to cope with en vironme ntal change. However, empirical evidenee of behavioral trait divergence across environmental extremes is lacking. We tested for variation in behavioral traits among 2 populations of an African cichlid fish (Pseudocrenilabrus multicolor victoriae Seegers, 1990) that experience extremes of dissolved oxygen (DO) and turbidity and are known to vary in a number of physiological and life history traits associated with these stressors. Using a comm on garden reari ng experime nt, F1 progeny from wild-caught parents originating from a swamp (low DO, clear) and a river (high DO, turbid) were reared in high DO, clear water. Predator simulation assays were conducted to test for (1) variation in boldness, general activity, and foraging activity between populations,(2) differences in correlations betwee n behaviors with in and across populati ons, and (3) repeatability of behaviors. There was strong evide nee for diverge nee betwee n populati ons, with swamp fish being more bold (i.e.z leaving refuge sooner after a simulated predator attack) and active (i.e., spent more time out of refuge) than river fish. Across populations there were positive correlations between foraging activity and both boldness and general activity;however, within populations, there was only a strong positive relationship between foraging activity and boldness in the river population. Here, we have demonstrated that populations that originate from drastically different environments can produce proge ny that exhibit measurable differences in behaviors and their correlated relati on ships eve n whe n reared un der comm on conditions.

3AUR Proteins as Effectors of Hormonal and Environmental Signals in Plant Growth

Molecular Plant 2015年第8期8卷 1153-1164页

作者： Hong Ren William M. gray Department of Plant Biology University of Minnesota 250 Biological Sciences Center 1445 Gortner Avenue St. Paul MN 55108 USA

The plant hormone auxin regulates numerous aspects of plant growth and development. Early auxin response genes mediate its genomic effects on plant growth and development. Discovered in 1987, SMALL AUXIN UP RNAs （SAURs） are the largest family of early auxin response genes. SAUR functions have remained elusive, however, presumably due to extensive genetic redundancy. However, recent molecular, genetic, biochemical, and genomic studies have implicated SAURs in the regulation of a wide range of cellular, physiological, and developmental processes. Recently, crucial mechanistic insight into SAUR function was provided by the demonstration that SAURs inhibit PP2C.D phosphatases to activate plasma membrane （PM） H＊-ATPases and promote cell expansion. In addition to auxin, several other hormones and environmental factors also regulate SAUR gene expression. We propose that SAURs are key effector outputs of hormonal and environmental signals that regulate plant growth and development.

HP30-2, a mitochondrial PRAT protein for import of signal sequence-less precursor proteins in Arabidopsis thaliana

引用

Journal of Integrative Plant Biology 2017年第8期59卷 535-551页

作者： Claudia Rossig John gray Oscar Valdes Sachin Rustgi Diter von Wettstein Christiane Reinbothe Steffen Reinbothe Laboratory of Plant Molecular Genetics and Laboratory of Environmental and Systems Biology Grenoble-Alpes-University Grenoble France Department of Biological Sciences University of Toledo 2801 West Bancroft Street Toledo OH 43606 USA Department of Plant and Environmental Sciences Pee Dee Research and Education Center Clemson University Florence SC 29506 USA Department of Crop and Soil Sciences Washington State University Pullman WA 99164-6420 USA

Chloroplasts and mitochondria contain a family of putative preprotein and amino acid transporters designated PRAT. Here, we analyzed the role of two previously characterized PRAT protein family members, encoded by At3g49560 （HP30） and At5g24650 （HP30-2）, in planta using a combination of genetic, cell biological and biochemical approaches. Expression studies and green fluorescent protein tagging identified HP30-2 both in chloroplasts and mitochondria, whereas HP30 was located exclusively in chloroplasts. Biochemical evidence was obtained for an association of mitochondrial HP30-2 with two distinct protein complexes, one containing the inner membrane translocase TIM22 and the other containing an alternative NAD（P）H dehydrogenase subunit （NDCI） implicated in a respiratory complex 1-1ike electron trans- port chain. Through its association with TIM22, HP30-2 is involved in the uptake of carrier proteins and other, hydrophobic membrane proteins lacking cleavable N H2-terminal presequences, whereas HP30-2＇s interaction with NDC1 may permit controlling mitochondrial biogenesis and activity.
