Induced plant defenses in response to herbivore attack are modulated by cross-talk between jasmonic acid (JA)- and salicylic (SA)-signaling pathways. Oral secretions from some insect herbivores contain effectors that overcome these antiherbivore defenses. Herbivores possess diverse microbes their digestive systems microbial symbionts can modify plant-insect interactions; however, the specific role of herbivore-associated manipulating remains unclear. Here, we demonstrate Colorado potato...
In planta RNAi against essential insect genes offers a promising route to control crop pests, but is constrained for many groups, notably phloem sap-feeding hemipterans, by poor efficacy. This study conducted on the phloem-feeding whitefly Bemisia tabaci reared tomato plants investigated causes of low efficacy and routes ameliorate problem. Experiments using transgenic lines containing ds-GFP (green fluorescent protein) revealed that full-length dsRNA phloem-mobile, ingested insects,...
Herbivore associated bacteria are vital mediators of plant and insect interactions. Host plants play an important role in shaping the gut bacterial community insects. Colorado potato beetles (CPB; Leptinotarsa decemlineata) use several Solanum as hosts their natural environment. We previously showed that symbiotic from CPB larvae suppressed jasmonate (JA)-induced defenses tomato. However, little is known about how changes may be involved manipulation induced wild cultivated CPB. Here, we...
As a popular tool for gene function characterization and therapy, RNA interference (RNAi)-based silencing has been increasingly explored potential applications to control invasive species. At least two major hurdles exist when applying this approach plants: (1) the design screening of species- gene-specific biomacromolecules (i.e., gene-silencing agents or GSAs) made DNA, RNA, peptides that can suppress expression target genes efficiently, (2) delivery vehicle needed penetrate plant cell...
Herbivore microbial associates can affect diverse interactions between plants and insect herbivores. Some symbionts enable herbivores to expand host plant range or facilitate use by modifying physiology. However, little attention has been paid the role of herbivore-associated microbes in manipulating defenses. We have recently shown that Colorado potato beetle secrete symbiotic bacteria suppress The oral secretions from hijack defense signaling pathways suppression induced defenses benefits...
A defining feature of the nutritional ecology plant sap-feeding insects is that dietary deficit essential amino acids (EAAs) in sap supplemented by EAA-provisioning microbial symbionts insect. Here, we demonstrated substantial variation phenotype 208 genotypes pea aphid Acyrthosiphon pisum collected from a natural population. Specifically, varied performance (larval growth rates) on four test diets lacking EAAs arginine, histidine and methionine or aromatic (phenylalanine tryptophan),...
Insect pest control by RNA interference (RNAi)-mediated gene expression knockdown can be undermined many factors, including small sequence differences between double-stranded (dsRNA) and the target gene. It also compromised effects that are independent of dsRNA on non-target organisms (known as sequence-non-specific effects). This study investigated species-specificity RNAi in plant sap-feeding hemipteran pests. We first demonstrated suppression aphid feeding at dietary concentrations ≥0.5...
Spodoptera frugiperda (fall armyworm) is a notorious pest that threatens maize production worldwide. Current control measures involve the use of chemical insecticides and transgenic expressing Bacillus thuringiensis (Bt) toxins. Although additional transgenes have confirmed insecticidal activity, limited research has been conducted in maize, at least partially due to technical difficulty transformation. Here, we describe implementation sugarcane mosaic virus (SCMV) vector for rapidly testing...
Abstract Previously, sugarcane mosaic virus (SCMV) was developed as a vector for transient expression of heterologous genes in Zea mays (maize). Here, we show that SCMV can also be applied virus‐induced gene silencing (VIGS) endogenous maize genes. Comparison sense and antisense VIGS constructs targeting phytoene desaturase (PDS) showed resulted greater reduction expression. In time course after infection with PDS , lesion mimic 22 ( Les22 ), Iodent japonica 1 Ij1 efficient observed 2, 3, 4...
Abstract Nicotiana benthamiana is used extensively as a transient expression platform for functional analysis of genes from other species. Acylsugars, which are produced in the trichomes, hypothesized cause relatively high insect resistance that observed N. . We characterized acylsugar profile, bioinformatically identified two acyltransferase genes, ASAT1 and ASAT2 , CRISPR/Cas9 mutagenesis to produce acylsugar-deficient plants investigation foliar water loss. Whereas asat1 mutations reduced...
