After traumatic spinal cord injury, functional deficits increase as axons die back from the center of the lesion and the glial scar forms. Axonal dieback occurs in two phases: an initial axon intrinsic stage that occurs over the first several hours and a secondary phase which takes place over the first few weeks after injury. Here, we examine the secondary phase, which is marked by infiltration...

To study the effect of Zn and B as foliar spray on growth and yield of sweet orange, cv. Blood red at Dargai, Malakand Agency, Pakistan during 2006 and 2007. The micronutrients zinc (Zn) in the form of zinc sulphate (ZnSo4.7H2O) as zinc source at the rate of 0.5 % and 1.0 % and boron (B) in the form of boric acid (H3BO3) at the rate of 0.02 % and 0.04 % were applied as foliar spray at three dif...

Severe droughts may increase physiological stress on long-lived woody vegetation, occasionally leading to rapid defoliation and progressive increase in mortality of overstorey trees. Over the last few years, episodes of drought-induced tree dieback have been documented in a variety of woodlands and forests around the world. However, the factors determining tree survival and subsequent recovery ...

The vascular pathogen Eutypa lata, which causes Eutypa dieback in grapevines, is a major threat to grape production worldwide. Here, we present the first draft genome sequence of E. lata (UCR-EL1). The computational prediction and annotation of the protein-coding genes of UCR-EL1 provide an initial inventory of its potential virulence factors.

Neofusicoccum parvum, a member of the Botryosphaeriaceae family, is a vascular pathogen that causes severe decline and dieback symptoms in grapevines worldwide. The draft genome of the grapevine isolate N. parvum UCR-NP2 provides a first glimpse into the complex set of putative virulence factors that this pathogen may use to rapidly colonize plants.

Pseudomonas syringae FF5 causes stem tip dieback disease on ornamental pear (Pyrus calleryana). Its genome encodes a complete type III secretion system (T3SS) and HopAC1, HopM1, AvrE1, HopI1, HopAA1, HopJ1, HopAH2, HopAH1, HopAG1, and HopAZ1. Lacking detectable homologues of other T3SS effectors, it may encode novel, undiscovered effectors.

Science for Conservation presents the results of investigations contracted to science providers outside the Department of Conservation. Reports are subject to peer review within the Department and, in some instances, to a review from outside both the Department and the science providers. The Efficacy of possum control in reducing forest dieback in the Otira and Deception Catchments, Central Wes...

Drought contributed to extensive dieback of southern California chaparral, and normalized difference vegetation index before drought near the end was used estimate this dieback, after accounting for other disturbances recorded in aerial photographs. Within perimeters two megafires that occurred drought, 2017 Thomas Fire 2018 Woolsey Fire, there had been areas dieback. Comparing with Monitoring ...

A recently published article describing the draft genome of Erwiniamallotivora BT-Mardi (1), the causal pathogen of papaya dieback infection in Peninsular Malaysia, hassignificant potential to overcome and reduce the effect of this vulnerable crop (2). The authors found that the draft genome sequenceis approximately 4824 kbp and the G+C content of the genomewas 52-54%, which is very similarto t...

Species in the family Botryosphaeriaceae are common pathogens causing fruit rot and dieback of many woody plants. In this study, 150 Botryosphaeriaceae isolates were collected from olive and other hosts in Spain and California. Representative isolates of each type were characterized based on morphological features and comparisons of DNA sequence data of three regions: internal transcribed space...
