Enzyme activity in terrestrial soil in relation to exploration of the Martian surface [PDF]

Sensitive tests for the detection of extracellular enzyme activity in Martian soil was investigated using simulated Martian soil. Enzyme action at solid-liquid water interfaces and at low humidity were studied, and a kinetic scheme was devised and tested

RNA tomography reveals spatial gene expression maps of Arabidopsis thaliana roots infected with Heterodera schachtii

New Phytologist, EarlyView.
Summary Plant‐parasitic cyst nematodes, such as Heterodera schachtii, cause substantial crop losses world‐wide and induce specialized feeding structures in host roots, yet the molecular mechanisms underlying feeding structure initiation and development remain poorly understood.

Chromosome‐level genome assembly of the photobiont microalga Trebouxia sp. ‘A48’ from the lichen Xanthoria parietina

New Phytologist, EarlyView.
Summary Lichens are symbiotic assemblies consisting of multiple organisms, chiefly a fungus and a photosynthetic microorganism, or photobiont. Among diverse photobionts, the most prevalent is the chlorophyte alga Trebouxia. We produced a chromosome‐level assembly of Trebouxia sp. ‘A48’, a photobiont of Xanthoria parietina. The genome was assembled into

Bacterial Involvement in Oral Squamous Cell Carcinoma and Potentially Malignant Oral Disorders

Oral Diseases, EarlyView.
ABSTRACT Objective To clarify the relationship between oral squamous cell carcinoma (OSCC), potentially malignant oral disease (OPMD), and bacterial flora using metagenomic analysis. Methods This cross‐sectional observational study included 50 patients in the control group and 77 patients with OPMDs, 41 with early OSCCs, and 20 with advanced OSCCs ...

Molecular changes in agroinfiltrated leaves of Nicotiana benthamiana expressing suppressor of silencing P19 and coronavirus‐like particles

Plant Biotechnology Journal, EarlyView.
Summary The production of coronavirus disease 2019 vaccines can be achieved by transient expression of the spike (S) protein of severe acute respiratory syndrome coronavirus 2 in agroinfiltrated leaves of Nicotiana benthamiana. Relying on bacterial vector Agrobacterium tumefaciens, this process is favoured by co‐expression of viral silencing suppressor

Purification, Characterization and Antifungal Activity of Chitinase from Serratia marcescens Isolated from Fresh Vegetables

Ibn Al-Haitham Journal for Pure and Applied Sciences, 2017
  Seven [35%] and five [25%] Serratia marcescens  isolates were obtained out of 20 samples of lettuce and 20 samples of spinach, respectively, taken from different locations in a farm in Baghdad city.

High yield production of the antifungal proteins PeAfpA and PdAfpB by vacuole targeting in a TMV‐based expression vector

Plant Biotechnology Journal, EarlyView.
Summary Antifungal proteins (AFPs) derived from filamentous fungi show great potential against economically significant fungi that cause plant diseases and consequently threat food safety and security. This study focuses on the Penicillium expansum PeAfpA and Penicillium digitatum PdAfpB proteins and their activity against several phytopathogens.
