Accurate and efficient estimation of forest growth and live biomass is a critical element in assessing potential responses to forest management and environmental change. The objective of this study was to develop models to predict longleaf pine tree diameter at breast height （dbh） and merchantable stem volume （V） using data obtained from field measurements. We used longleaf pine tree data from 3,376 planted trees on 127 permanent plots located in the U.S. Gulf Coastal plain region to fit equations to predict dbh and V as functions of tree height （H） and crown area （CA）. prediction of dbh as a function of H improved when CA was added as an additional independent variable. Similarly, predic- tions of V based on H improved when CA was included. Incorporation of additional stand variables such as age, site index, dominant height, and stand density were also evaluated but resulted in only small improvements in model performance. For model testing we used data from planted and naturally-regenerated trees located inside and outside the geographic area used for model fitting. Our results suggest that the models are a robust alternative for dbh and V estimations when H and CA are known on planted stands with potential for naturally-regenerated stands, across a wide range of ages. We discuss the importance of these models for use with metrics derived from remote sensing data.

A peroxidase Contributes to ROS production during Arabidopsis Root Response to potassium Deficiency

Molecular plant 2010年第2期3卷 420-427页

作者： Min Jung Kim Silvano Ciani daniel p. Schachtman Donald Danforth plant Science Center 975 North Warson Road St Louis MO 63132 USA present address: Department of Biology Washington University in St Louis St Louis MO 63130 USA present address: Monsanto Company St Louis MO 63017 USA

Reactive oxygen species （ROS） play an important role in root responses to potassium deprivation by regulating the expression of the high-affinity K＋ transporter gene AtHAK5 and other genes. Activation-tagged lines of Arabidopsis plants containing the AtHAK5 promoter driving luciferase were screened for bioluminescence under potassium- sufficient conditions. A member of the type Ill peroxidase family, RCI3, was isolated and when it was overexpressed by the activation tag, this led to the enhanced expression of luciferase and the endogenous AtHAKS. RCI3 was found to be up- regulated upon potassium deprivation. plants overexpressing RCI3 （RCI3-ox） showed more ROS production and AtHAK5 expression whereas the ROS production and AtHAK5 expression were reduced in rci3-1 under K＋-deprived conditions. These results suggested that RCI3 is involved in the production of ROS under potassium deprivation and that RCI3- mediated ROS production affects the regulation of AtHAK5 expression. This peroxidase appears to be another component of the low-potassium signal transduction pathway in Arabidopsis roots.

IL-34 is a novel biomarker for rheumatoid arthritis(RA),as its serum levels are linked to C-reactive protein,erythrocyte sedimentation rate,rheumatoid factor(RF),IL-6 and radiographic progression[1,2].IL-34 reprograms naïve circulating M0 cells into glycolytic(CD14^(+)CD86^(+)GLUT1^(high))M34 macrophages(MΦs)by binding to its pathogenic receptor,SDC-1,which controls the activation of its coreceptor/M-CSFR[3].Glycolytic M34 MΦs are primed to differentiate into osteoclasts through SDC-1 ligation[3].
