a significant aspect is the cross-kingdom RNAi mechanism, whereby sRNAs can traverse organismal boundaries. Fungi utilize sRNA as an effector molecule to silence plant resistance genes, while plants transport sRNA, primarily through extracellular vesicles, to pathogens in order to suppress virulence-rela...

Van Beneden’s work covered a wide range of parasites in diverse animals and culminated with his Les Commensaux et les parasites dans le règne animal (1875; “Commensals and Parasites in the Animal Kingdom”). About 1859 he began a study of fossil and recent whales, which resulted in a...
the students had received no specific training or preparation for identifying plants. The students went through the normal school curriculum, which focused on plant and species identification in the 7th grade. Since the field-trip was part of the regular biology class, all students were required to...

This comparison suggests that the dominance of APx in the chloroplast antioxidant system [11] is not ubiquitous in the plant kingdom and may mainly be characteristic for higher land plants, for which it was first described [2]. Chloroplast ascorbate peroxidase genes share a common evolutionary ...
