Expressed sequenced tags from Lygus lineolaris (Hemiptera: Miridae), the tarnished plant bug.
Expressed sequenced tags (ESTs) were prepared to establish a baseline for molecular genetic studies of the tarnished plant bug, Lygus lineolaris (Palisot de Beauvois). The largest class of identifiable ESTs (15.2%) was from genes involved in cellular metabolic functions, including physiological processes. Twenty-seven ESTs (9.8%) were from genes associated with transcription and translation, in...
متن کاملDiet Selection Exhibited by Juvenile and Adult Lifestages of the Omnivores Western Tarnished Plant Bug, Lygus hesperus and Tarnished Plant Bug, Lygus lineolaris
Lygus hesperus Knight and Lygus lineolaris (Palisot de Beauvois) (Heteroptera: Miridae) are economically important plant bugs on many crops worldwide. However, these omnivores are also facultative predators on a wide variety of insects. This study was conducted to quantify and compare herbivory and carnivory exhibited among different lifestages of these two insect pests. The feeding activity of...
متن کاملExpression and RNA Interference of Salivary Polygalacturonase Genes in the Tarnished Plant Bug, Lygus lineolaris
Three genes encoding polygalacturonase (PG) have been identified in Lygus lineolaris (Palisot de Beauvois) (Miridae: Hemiptera). Earlier studies showed that the three PG gene transcripts are exclusively expressed in the feeding stages of L. lineolaris. In this report, it is shown that all three transcripts are specifically expressed in salivary glands indicating that PGs are salivary enzymes. T...
متن کاملMolecular Cloning and Expression of Three Polygalacturonase cDNAs from the Tarnished Plant Bug, Lygus lineolaris
Three unique cDNAs encoding putative polygalacturonase enzymes were isolated from the tarnished plant bug, Lygus lineolaris (Palisot de Beauvois) (Hemiptera: Miridae). The three nucleotide sequences were dissimilar to one another, but the deduced amino acid sequences were similar to each other and to other polygalacturonases from insects, fungi, plants, and bacteria. Four conserved segments cha...
متن کاملCloning and expression profiling of odorant-binding proteins in the tarnished plant bug, Lygus lineolaris.
In insects, the perception and discrimination of odorants requires the involvement of odorant-binding proteins (OBPs). To gain a better molecular understanding of olfaction in the agronomic pest Lygus lineolaris (the tarnished plant bug), we used a transcriptomics-based approach to identify potential OBPs. In total, 33 putative OBP transcripts, including the previously reported Lygus antennal p...
