Interactions Between Nanoparticles and Tomato Plants: Influencing Host Physiology and the Tomato Leafminer's Molecular Response.

Tomatoes are a crucial global crop, impacting economies and livelihoods worldwide. However, pests like the tomato leafminer () significantly reduce their yield potential. Nanoparticles come as a solution to this context, promising innovative strategies for the protection of plants from pest infestation and management.

The Diversity of and Other Bacterial Symbionts in .

Bacterial symbionts associated with insects can be crucial in insect nutrition, metabolism, immune responses, development, and reproduction. However, the bacterial symbionts of the fall armyworm remain unclear. is an invasive polyphagous pest that severely damages many crops, particularly maize and wheat.

Core promoter regulates the expression of cathepsin B gene in the fat body of Bombyx mori.

Bombyx mori cathepsin B (BmCatB) is involved in the programmed cell death of the fat body during B. mori metamorphosis. For a better understanding of the functional regulatory mechanism, the promoter region of BmCatB in the transcriptional regulation has been identified and analyzed in the present study.

Identification and functional analysis of the cathepsin D gene promoter of Bombyx mori.

The gene encoding cathepsin D of silkworm, Bombyx mori (BmCatD) is specifically expressed in the larval fat body and pupal gut, and plays an important role in the programmed cell death during metamorphosis. To identify element involved in this transcription-dependent spatial restriction, truncation and deletion of the 5' terminal from the BmCatD promoter were conducted in vivo. The recombinant AcMNPV vector (Autographa californica multiple nucleopolyhedrovirus) with a dual-luciferase quantitative assay system was used as the transfer.
