AI Article Synopsis
- The cosmopolitan flea beetle genera are associated mainly with Brassicaceae plants and include significant pests for crucifer crops.
- The review summarizes host plant associations and geographical distributions of these beetles, along with their phylogenetic relationships based on molecular studies.
- It is noted that while most species are specialized on Brassicaceae, others feed on a variety of plant families, and the authors suggest that these genera may have independently adapted to these plants' chemical defenses.
Article Abstract
The cosmopolitan flea beetle genera and (Galerucinae, Alticini) are mainly associated with host plants in the family Brassicaceae and include economically important pests of crucifer crops. In this review, the host plant associations and geographical distributions of known species in these genera are summarised from the literature, and their proposed phylogenetic relationships to other Alticini analysed from published molecular phylogenetic studies of Galerucinae. Almost all species are specialised on Brassicaceae and related plant families in the order Brassicales, whereas species are associated with host plants in approximately 24 different plant families, and 50% are specialised to feed on Brassicaceae. The current knowledge on how and are adapted to the characteristic chemical defence in Brassicaceae is reviewed. Based on our findings we postulate that and colonised Brassicaceae independently from each other.

Parasitic plants are a diverse and unique polyphyletic assemblage of flowering plants that survive by obtaining resources via direct vascular connections to a host plant. Ecologically important in their native ecosystems, these typically cryptic plants remain understudied and fundamental knowledge of the biology, ecology, and evolution of most species is lacking. This gap limits our understanding of ecosystems and conservation management.

Although plant secretory tissues play important roles in host defense against herbivores and pathogens and the attraction of insect pollinators, their genetic control remains elusive. Here, it is focused that current progress has been made in the genetic regulatory mechanisms underpinning secretory tissue development in land plants. C1HDZ transcription factors (TFs) are found to play crucial roles in the regulation of internal secretory tissues in liverworts and as well as external secretory tissues in peach.

Transient expression in Tobacco is a popular way to produce recombinant proteins in plants. The design of various expression vectors, delivered into the plant by , has enabled high production levels of some proteins. To further enhance expression, researchers often adapt the coding sequence of heterologous genes to the host, but this strategy has produced mixed results in Tobacco.

Oolong tea, a popular traditional Chinese tea, possesses various bioactivities, but little is known about its roles in the protection against pathogens, such as Staphylococcus aureus, in vivo. This study investigated the roles of the water-soluble oolong tea extracts (OTE) on S. aureus infection in Caenorhabditis elegans, a promising model to study the host-microbe interactions in vivo.
