Flowering plants and mammals contain imprinted genes that are primarily expressed in the endosperm and placenta in a parent-of-origin manner. In this study, we show that early activation of the geminivirus genes and in Arabidopsis () plants, encoding a viral suppressor of RNA interference and a replication enhancer protein, respectively, is correlated with the transient vegetative expression of (), an endosperm imprinted gene that is conserved in diverse plant species. VIM5 is a ubiquitin E3 ligase that directly targets the DNA methyltransferases MET1 and CMT3 for degradation by the ubiquitin-26S proteasome proteolytic pathway.

Article Synopsis
  • Gut microbes help in digestion and nutrient absorption, but research on freshwater snails like Pomacea canaliculata is limited; studying their microbiota can shed light on the snail's invasive behavior.* -
  • In a study of P. canaliculata, microbiota diversity was highest in the intestine and lowest in the buccal mass, identifying 29 phyla and 111 genera of bacteria, with Ochrobactrum being the most abundant.* -
  • The gut microbiome composition varies across different gut sections, indicating that specific bacteria, particularly cellulose-degrading types, thrive in the snail's digestive system.*

Objective: To investigate the effects of enriched environment and impoverished environment on the learning and memory ability of manganese-exposed mice and the mechanism.

Methods: Forty female Kunming mice were randomly and equally divided into 4 group: control group (CG), standard environment and manganese exposure group (SEG), enriched environment and manganese exposure group (EEG), and impoverished environment and manganese exposure group (IEG). The mouse model of manganese poisoning was established by intraperitoneal injection of manganese chloride.
