The intricate relationship between herbivorous insects and plants has evolved over millions of years, central to this dynamic interaction are salivary proteins (SPs), which mediate key processes ranging from nutrient acquisition plant defense manipulation. SPs, sourced glands, intestinal regurgitation or acquired through horizontal gene transfer, exhibit remarkable functional versatility, influencing insect development, behavior, adhesion mechanisms. Moreover, SPs play pivotal roles in modulating defenses, induce inhibit defenses as elicitors effectors. In review, we delve into the multifaceted insects, highlighting their diverse impacts on physiology responses. Through a comprehensive exploration SP functions, review aims deepen our understanding plant-insect interactions foster advancements both fundamental research practical applications interactions.

The mirid bug (Riptortus pedestris), a major soybean pest, migrates into fields during the pod filling stage and causes staygreen syndrome, which leads to substantial yield losses. mechanism by R. pedestris elicits (Glycine max) defenses counter-defenses remains largely unexplored. In this study, we characterized protein family from pedestris, designated Riptortus HAMP 1 (RPH1) its putative paralogs (RPH1L1, 2, 3, 4, 5), whose members exhibit dual roles in triggering inhibiting plant immunity. RPH1 RPH1L1 function as herbivore-associated molecular patterns (HAMPs), activating pattern-triggered immunity (PTI) tobacco (Nicotiana benthamiana) G. max. Furthermore, stimulates jasmonic acid ethylene biosynthesis max, thereby enhancing resistance feeding. Additionally, homologs are universally conserved across various herbivorous species, with many also acting HAMPs that trigger Interestingly, remaining (RPH1L2-5) serve effectors counteract RPH1-induced PTI, likely disrupting extracellular perception of RPH1. This research uncovers both chewing piercing-sucking insects. Moreover, it unveils an evasion utilized herbivores circumvent using functionally differentiated paralogs.

The oral secretions of insect herbivores are complex mixtures organic and inorganic solutes enzymes that deposited onto plant tissues during the feeding process. Some specific components have been shown to confer important functions in mediating plant-insect interactions at molecular level. In this review, we examined biochemical studies summarize current knowledge their compositions. We then moved beyond functional secretions, focused on literature pinpointed targets these compounds. Finally, highlighted investigations secretion context physiology, which shed light potential evolutionary trajectory multi-functional molecules.

Abstract Glycoside hydrolases are enzymes that break down complex carbohydrates into simple sugars by catalyzing the hydrolysis of glycosidic bonds. There have been multiple instances adaptive horizontal gene transfer genes belonging to various glycoside hydrolase families from microbes insects, as can metabolize constituents carbohydrate-rich plant cell wall. In this study, we characterize a family 26 (GH26) bacteria insects order Hemiptera. Our phylogenies trace common ancestor superfamilies Pentatomoidea and Lygaeoidea, which include stink bugs seed bugs. After transfer, was assimilated insect genome indicated gain an intron, eukaryotic signal peptide. Subsequently, has undergone independent losses expansions in copy number lineages, suggesting role GH26s some insects. Finally, measured tissue-level expression large milkweed bug using publicly available RNA-seq datasets. We found GH26 highly expressed tissues associated with digestion, especially principal salivary glands results consistent hypothesis horizontally transferred co-opted aid tissue digestion HGT event likely adaptive.

ABSTRACT Salivary proteins secreted by phytophagous insects play pivotal roles in plant–insect interactions. A salivary protein RpSP27, from the stinkbug Riptortus pedestris , a devastating pest on soybean, was selected for studying due to its ability induce cell death and activate immune responses plants. RpSP27 localized endoplasmic reticulum triggered reactive oxygen species burst. Virus‐induced gene silencing assays showed RAR1 plays an essential role RpSP27‐induced Nicotiana benthamiana . Expression analyses revealed that is predominantly expressed R. glands. RNA interference‐mediated of significantly reduced insect survival rates altered feeding behavior decreasing formation sheaths soybeans reducing probing duration. Furthermore, mitigated staygreen syndrome soybeans, characterized delayed senescence pod abnormalities. This study elucidated interaction between presenting potential target management strategies protect soybean crops detrimental effects feeding.
