LysM Receptor-Like Kinase LYK9 of L. May Regulate Plant Responses to Chitooligosaccharides Differing in Structure.

This study focused on the interactions of pea ( L.) plants with phytopathogenic and beneficial fungi. Here, we examined whether the lysin-motif (LysM) receptor-like kinase LYK9 is directly involved in the perception of long- and short-chain chitooligosaccharides (COs) released after hydrolysis of the cell walls of phytopathogenic fungi and identified in arbuscular mycorrhizal (AM) fungal exudates.

Antibodies raised against a Sunn bug ( Put.) recombinant protease, rGHP3p2, can inhibit gluten-hydrolyzing activity.

Sunn pest or Sunn bug, Put., salivary gland proteases are responsible for the deterioration of wheat flour quality during dough mixing, resulting from gluten hydrolysis. These proteases are highly heterogeneous and show low sensitivity to most types of proteinaceous inhibitors, meaning that such inhibitors cannot be used to prevent gluten damage.

Hexokinase as a versatile molecular genetic marker for Microsporidia.

Hexokinase (HK) is a core glycolytic enzyme of Microsporidia which regulates host cell metabolic processes. The goal of the present study was to test for the utility of HK for molecular phylogenetics, species identification and molecular detection of microsporidia in infected insects. HK sequence-based reconstructions were essentially similar to those based upon largest subunit RNA polymerase (RPB1) gene sequences, as well as previously published rRNA gene and genome-based trees.

Ultrastructure and molecular phylogeny of Anisofilariata chironomi g.n. sp.n. (Microsporidia: Terresporidia) from Chironomus plumosus L. (Diptera: Chironomidae).

Larvae of Chironomus plumosus, collected in North-Western Russia in September 2008, were infected with a microsporidium possessing broadly oval uninucleate spores in sporophorous vesicles. Sporogony and spore ultrastructure of this microsporidium differed from that of known microsporidian species, suggesting establishment of a new species, Anisofilariata chironomi, being a type species of a new genus. Sporogony di-, tetra-, octo-, and 16-sporoblastic.
