Fusarium wilt of banana is a devastating disease that has decimated banana production worldwide. Host resistance to Fusarium oxysporum f. sp. Cubense (Foc), the causal agent of this disease, is genetically dissected in this study using two Musa acuminata ssp. Malaccensis segregating populations, segregating for Foc Tropical (TR4) and Subtropical (STR4) race 4 resistance. Marker loci and trait association using 11 SNP-based PCR markers allowed ...

During a survey of plant diseases in the Central Highlands of Vietnam, a new plant-parasitic nematode, Hemicycliophora cardamomi sp. n., was discovered in the growing areas of Amomum longiligulare, a valuable medicinal plant with high economical value. The new species is characterized by a cuticular sheath loosely fitting body; a labial region continuous to the body contour bearing 3 annuli; a lateral field frequently marked by a discontinuous ...

Five strains of Gram-stain-negative, rod-shaped bacteria were isolated from Carmichaelia and Montigena root nodules. Based on 16S rRNA gene phylogeny, they were shown to belong to the genus Mesorhizobium, and to be most closely related to Mesorhizobium jarvisii ATCC 33669(T) (100-99.6 % sequence similarity), Mesorhizobium huakuii IAM 14158(T) (99.9-99.6 %), Mesorhizobium japonicum MAFF303099(T) (99.8-99.6 %) and Mesorhizobium erdmanii USDA ...

To our knowledge, to date, no nonempirical method exists to measure reverse, low or high sap flux density. Moreover, existing sap flow methods require destructive wood core measurements to determine sapwood water content, necessary to convert heat velocity to sap flux density, not only damaging the tree, but also neglecting seasonal variability in sapwood water content. Here, we present a nonempirical heat-pulse-based method and coupled sensor ...

An increasing global focus on neglected tropical diseases (NTDs) has resulted in the set up of numerous control and elimination activities worldwide. This is partly true for Taenia solium taeniasis/cysticercosis, the most important foodborne parasitic infection. Despite substantial progress, adequate monitoring and surveillance (M&S) are required to sustain a status of control/elimination. This is often lacking, especially for T. solium. ...

Aims. This study utilises a modelling approach to investigate the impact of perturbed solar wind conditions caused by multiple ICMEs on the evolution of SEP distributions. Furthermore, we demonstrate the utility of SEP models in evaluating the performance of solar wind and CME models. To illustrate these concepts, we focus on modelling the gradual SEP event that occurred on March 15, 2013. Methods. We utilise the 3D magnetohydrodynamic model ...

The European Commission requested the EFSA Panel on Plant Health to evaluate the probability of entry of pests (likelihood of pest freedom at entry), including both regulated and non-regulated pests, associated with unrooted cuttings of the genera Petunia and Calibrachoa produced under physical isolation in Costa Rica. The relevance of any pest for this opinion was based on evidence collected according to specific criteria, following the ...
