Nematodes are tiny but complex unsegmented roundworms that are anatomically differentiated for feeding, digestion, locomotion, and reproduction. These small animals occur worldwide in all environments. Most species are beneficial to agriculture. They make important contributions to organic matter decomposition and to the food chain. Some species, however, are parasitic to plants or animals. Pla...

Identification of reliable molecular markers that show differential expression between distinct groups of samples has remained a fundamental research problem in many large-scale profiling studies, such as those based on DNA microarray or mass-spectrometry technologies. Despite the availability of a wide spectrum of statistical procedures, the users of the high-throughput platforms are still fac...

Sweet chestnut fruits are popular commercialized as fresh or processed ready-to-eat products. The major post-harvest problems associated with stored fungal rots, which cause losses in fruit quality. aims of this work were to determine the incidence, abundance and diversity rots fungi three varieties (Longal, Judia Martaínha) Portugal, collected from an industrial plant, identify stages storage ...

In this paper we generalize the notion of an ι-symmetric word, from an antimorphic involution, to an arbitrary involution ι as follows: a nonempty word w is said to be ι-symmetric if w = αβ = ι(βα) for some words α, β . We propose the notion of ιtwin-roots (x, y) of an ι-symmetric wordw. We prove the existence and uniqueness of the ι-twin-roots of an ι-symmetric word, and show that the left fac...

A collection of 53 antibiotic-producing Streptomyces isolated from soils from Minnesota, Nebraska, and Washington were evaluated for their ability to inhibit plant pathogenic Phytophthora medicaginis and Phytophthora sojae in vitro. Eight isolates having the greatest pathogen-inhibitory capabilities were subsequently tested for their ability to control Phytophthora root rots on alfalfa and soyb...
