Planarians can regenerate any missing body part in a process requiring dividing cells called neoblasts. Historically, neoblasts have largely been considered a homogeneous stem cell population. Most studies, however, analyzed neoblasts at the population rather than the single-cell level, leaving the degree of heterogeneity in this population unresolved. We combined RNA sequencing of neoblasts fr...

Urban trees are one of the valuable storage in metropolitan areas. Nowadays, a particular attention is paid to and spends million dollars per year their maintenance. Trees often subjected abiotic factors, such as fungi, bacteria, insects, which lead decline mechanical strength wood properties. The objective this study was determine potential degradation Elm tree by Phellinus pomaceus Biscogniau...

Members of Xylariaceae (Ascomycota) are recognized and classified mainly on the morphological features of their sexual state. In a number of genera high morphological variation of stromatal characters has made confident recognition of generic and specific boundaries difficult. There are, however, a range of microscopical characteristics which can in most cases make distinctions, especially at g...

Karst caves are distinctly characterised by darkness, low to moderate temperatures, high humidity, and scarcity of organic matter. During the years of 2014-2015, we explored the mycobiota in two unnamed Karst caves in Guizhou province, China, and obtained 563 fungal strains via the dilution plate method. Preliminary ITS analyses of these strains suggested that they belonged to 246 species in 11...

Two insect growth regulators, methoprene and a benzyl-1,3,benzodioxole (J-2931), had no detrimental effects on Dugesia tigrina under field conditions. Three other compounds, resmethrin, temephos, and cyromazine, had only minimal effects. Asexual multiplication among these planarian predators exceeded 68% when combined with Culex quinquefasciatus larvae and methoprene at different concentration ...

We present the Wrst study of the eVects of ocean acidiWcation on settlement of benthic invertebrates and microfauna. ArtiWcial collectors were placed for 1 month along pH gradients at CO2 vents oV Ischia (Tyrrhenian Sea, Italy). Seventy-nine taxa were identiWed from six main taxonomic groups (foraminiferans, nematodes, polychaetes, molluscs, crustaceans and chaetognaths). Calcareous foraminifer...

one of the most important and elusive diseases of grapevine is esca disease. esca is a complex disease that comprises a combination of symptoms caused by various fungi including growth retardation, decrease in productivity and decline of the plant and usually affecting adult plants (8 to 10 years and older). the purpose of this research was to study the genetic variations of fungal agents assoc...

Planarians have been used as a model to study development and regeneration for more than 200 years. Research on these animals has traditionally focused on surgical and pharmacological manipulations. Recently, the dissection of planarians has become more molecular in nature. The isolation of thousands of expressed sequence tags and the introduction of in situ hybridizations, immunocytology, and ...
