Xylella fastidiosa (Xf) is a vascular plant pathogen native to the Americas. In 2013, it was first reported in Europe, implicated massive die-off of olive trees Apulia, Italy. This finding prompted mandatory surveys across successively revealing that bacterium already established some distant areas western Mediterranean. To date, Balearic Islands (Spain) hold major known genetic diversity Xf Eu...

Sustainable natural rubber (NR) foams were prepared by replacing petroleum-based carbon black (CB) with recycled silica (SiO2) nanoparticles. The total nanofillers concentration was fixed at 40 phr, while the CB/silica ratio changed from 40/0 to 0/40. results showed that increasing content increased curing characteristics, such as delta torque (∆M) 54%, scorch time (ts) 50% and optimum (t90) 65...

Abstract To understand the potential of forests to adapt wildfire, we studied genetic architecture fire-related structural, damage and recovery traits in a globally important Australian forest tree species, Eucalyptus globulus . Fourteen were evaluated an outcrossed F 2 population field trial Tasmania, Australia, which was burnt by wildfire 14 years after planting. The also included open-pollin...

In southeastern Arkansas, pine growth was monitored for 19 yr after mechanically strip thinning a dense, naturally regenerated, even-aged stand of Gyr-old loblolly pines (Pinus taeda L.) and shortleafpines (P. echinata Mill.) that averaged 16,600 stems/UC. Prescribed winter burns were conducted biennial ly between ages 9 and 20 yr and at 24 yr . Commercial th innings during the 17th and 23rd gr...

Spontaneous point mutations of virus genomes are important in RNA virus evolution and often result in modifications of their biological properties. Spontaneous variants of beet black scorch virus (BBSV) and its satellite (sat) RNA were generated from cDNA clones by serial propagation in Chenopodium amaranticolor and Nicotiana benthamiana. Inoculation with recombinant RNAs synthesized in vitro r...
