Identification of Multifunctional Putative Bioactive Peptides in the Insect Model Red Palm Weevil ().

Innate immunity, the body's initial defense against bacteria, fungi, and viruses, heavily depends on antimicrobial peptides (AMPs), which are small molecules produced by all living organisms. Insects, with their vast biodiversity, are one of the most abundant and innovative sources of AMPs. In this study, AMPs from the red palm weevil (RPW) (Coleoptera: Curculionidae), a known invasive pest of palm species, were examined.

First report of apple hammerhead viroid infecting apple trees in Montenegro.

Apple hammerhead viroid (AHVd, Pelamoviroid, Avsunviroidae) is one of the five viroids infecting apples. It has been identified on all continents except Australia since its viroid nature was confirmed (DiSerio et al. 2018; CABI and EPPO 2022).

Deorphanizing an odorant receptor tuned to palm tree volatile esters in the Asian palm weevil sheds light on the mechanisms of palm tree selection.

The Asian palm weevil, Rhynchophorus ferrugineus, is a tremendously important agricultural pest primarily adapted to palm trees and causes severe destruction, threatening sustainable palm cultivation worldwide. The host plant selection of this weevil is mainly attributed to the functional specialization of odorant receptors (ORs) that detect palm-derived volatiles. Yet, ligands are known for only two ORs of R.

The effect of phytosulfokine alpha on haploid embryogenesis and gene expression of microspore cultures.

Microspore embryogenesis (ME) is the most powerful tool for creating homozygous lines in plant breeding and molecular biology research. It is still based mainly on the reprogramming of microspores by temperature, osmotic and/or nutrient stress. New compounds are being sought that could increase the efficiency of microspore embryogenesis or even induce the formation of haploid embryos from recalcitrant genotypes.
