Phylogenetic and structural characterization of Kentomonas inusitatus n. sp.: Unique insect trypanosomatid of the Strigomonadinae subfamily naturally lacking bacterial endosymbiont.

All insect trypanosomatids of the subfamily Strigomonadinae harbor a proteobacterial symbiont in their cytoplasm and unique ultrastructural cell organization. Here, we report an unexpected finding within the Strigomonadinae subfamily: the identification of a new species lacking bacterial symbiont, represented by two isolates obtained from Calliphoridae flies in Brazil and Uganda. This species is hereby designated as Kentomonas inusitatus n.

S-metolachlor in pre-emergence reduces the leaf cuticular wax and increases the efficiency of glyphosate.

Background: The low glyphosate uptake capacity, possibly due to the lipophilic character of epicuticular wax on leaves, may contribute to the natural tolerance of some weed species. The use of pre-emergence herbicides like S-metolachlor, which inhibits very-long-chain fatty acid synthesis, might enhance glyphosate's post-emergent efficacy against hard-to-control weeds, such as Euphorbia heterophylla L. (milkweed) and Ipomoea triloba L.

Advances on polymeric nanocarriers for sustainable agriculture: Enhancing dsRNA/siRNA delivery to combat agricultural pests.

The application of exogenous RNA for gene-silencing strategies has gained significant traction in agriculture, offering a highly efficient and eco-friendly alternative to conventional plant protection methods. This success has been driven by advances in biotechnology, from the design of long double-stranded RNA (dsRNA) and small interfering RNA (siRNA) molecules to the development of nanocarrier systems that address the challenge of RNA delivery into plant cells. In particular, polymer-based nanocarriers have emerged as a promising solution for enhancing the stability and delivery efficiency of RNA molecules.
