Aphis pseudocomosa which has the longest hair on the third antennal segment 0.67-1.38 times the basal diameter of that segment). doi: 10.1093/nar/gku1221, 37. In addition, most neuropeptide signalings are conserved in both holometabolous and hemimetabolous insects, suggesting that they play key roles in the physiological processes of insects (3). CDD analysis indicated that A40 has 15 LRR motifs and no LDLa motif, showing typical structural characteristics of a type B LGR. Applied Entomology and Zoology, Vol. Three restriction enzymes Rsa I, AluI and Hinf1 produced patterns that allowed unambiguous identification of the species except Aphis craccivora and Aphis fabae. doi: 10.1038/nmeth.1701, 33. Moreover, a homologous sequence (ARM65502.1) was also found in A. pisum by the Blast program. During the spring season on the hibiscus plants in our backyard, we find this aphid. Miller, AphID. Except for a few families of neuropeptides, such as prothoracicotropic hormone (PTTH), eclosion hormone (EH), and neuropeptide-like precursor 1 (NPLP1), the majority of neuropeptide receptors belong to the G protein-coupled receptors (GPCRs) superfamily (3).

They are the most abundant and diverse signal molecules and play important regulatory roles in the physiology and behavior in insects such as the growth, development, metabolism, reproduction, and feeding of insects (2). (2010) 92:42–104. Also most of the surveyed populations were polymorphic for facultative symbiont infection, indicating that even when symbiont prevalence is relatively low, symbiont-associated phenotypic variation may allow population-level evolutionary responses to local selection. doi: 10.1126/science.1124128, 26. The main species of aphids attacking beans are Aphis fabae Scopoli and Aphis craccivora Koch. It is speculated that A. craccivora likely lacks the above neuropeptide signaling pathways, which is consistent with Acyrthosiphon pisum and that the loss of these pathways may be a common feature of aphids. In silico analyses of peptide paracrines/hormones in Aphidoidea. doi: 10.1126/science.aac6767, 53. The tree is rooted by the serotonin receptor CG1056 from D. melanogaster.

The main species of aphids attacking beans are Aphis fabae Scopoli and Aphis craccivora Koch. Swati Das. Aphis craccivora, variously known as the cowpea aphid, groundnut aphid or black legume aphid, is a true bug in the family Aphididae. However, whether the differential temporal expressions of these genes have a biological role on development needs further investigation. From the RPKM values, the expression abundance of ILP5 gene in A. craccivora is much higher than other ILP-encoding genes, which is consistent with that reported in A. pisum (80).

Even the sequences of mature peptides of DH31 and DH44 that are up to tens of amino acids are identical in A. craccivora and A. pisum (Supplementary Material 2). (1990) 247:1333–5. Brown citrus aphids are considered one of the most serious pests of citrus. The predicted A. craccivora SIFa sequence (FRKPPFNGSIFamide) is consistent with that of A. pisum and M. persicae, but lacks an amino acid residue at the N-terminus compared to the classical motif. Separation and identification of biologically active compounds of the wild plant, Atriplex semibaccata against Aphis craccivora Koch. In addition, 46 neuropeptide GPCRs were obtained, of which 40 belong to rhodopsin-like receptors (A-family GPCRs), including 21 families of neuropeptide receptors and 7 orphan receptors, and 6 belong to secretin-like receptors (B-family GPCRs), including receptors for diuretic hormone 31, diuretic hormone 44 and pigment-dispersing factor (PDF).

Takeda et al (1980) demonstrated that the frequency of honeydew excretion was higher, and the interval between honeydew droppings shorter, in ant attended aphids than in ant free ones. We select 40S ribosomal protein S8 gene (RPS8) as the reference gene to normalize the expression of the target genes (39). Gen Comp Endocrinol. 2009).Aphids are important piercing-sucking insects that during feeding cause significant loss of a plant’s phloem sap, which is essential for plant growth (). Molecular cloning of the Bombyx mori prothoracicotropic hormone. Front Endocrinol. Neuropeptide receptors A1–A40 are abbreviated as A1–A40, respectively; Neuropeptide receptors B1–B6 are abbreviated as B1–B6, respectively. Kamphuis LG, Gao L and Singh KB. We also conducted structural analysis and mature peptide prediction for the identified neuropeptide precursors and classified the neuropeptide receptors into subclasses based on phylogenetic analysis. Cowpea aphid, Aphis craccivora Koch is a polyphagous pest of cowpea that attacks the crop, feeding on all plant parts and leading to significant yield losses [10–12]. Author information: (1)CSIRO Plant Industry, Wembley, WA, Australia. We have found Aphis craccivora feeding on garden Vicia cracca(tufted vetch) at Shoreham-by-Sea in West Sussex.

Wei ZJ, Zhang QR, Kang L, Xu WH, Denlinger DL. Katoh K, Standley DM. In addition to ITP peptide, the ITP gene also encodes an alternatively spliced variant without C-terminal amidation (known as ITP-like or ITPL) (64). Genus: Aphis Subject: Aphis craccivora Koch, 1854 Other System Links. (2001) 2:reviews3013–1. Based on RNA-seq technology, we identified a large number of genes encoding neuropeptides and their GPCRs from A. craccivora in this study. The limited strain diversity observed for these defensive elements may also result in relatively static protection profile for this defensive symbiosis. Worldwide populations of the aphid Aphis craccivora are infected with diverse facultative bacterial symbionts. MAFFT multiple sequence alignment software version 7: improvements in performance and usability. References. The cowpea aphid, Aphis craccivora Koch, is the principal pest of bean crops in this region. Phylogenetic analysis revealed that A. craccivora B1, B3, and B4 were clustered in the branch of DH31 receptor; B5 and B6 were clustered in the branch of DH44 receptor; and B2 was clustered in the branch of PDF receptor (Figure 4). In this study, a total of 5 LGRs (A36-A40) were identified from A. craccivora (Figure 3). Some mature neuropeptide sequences are identical in different aphids, such as short neuropeptide F (sNPF) and SIFamide (SIFa) of A. craccivora, A. pisum, and Myzus persicae. Many North American and a few southern European Aphis craccivora populations have a reduced sclerotic shield. And the expression of these genes at different developmental stages of A. craccivora was analyzed by quantitative real-time PCR (qRT-PCR). (2020) 11:159. doi: 10.3389/fphys.2020.00159, 10. Statistical significance was evaluated using one-way ANOVA followed by the Tukey HSD test at the 0.05 level. Aphis craccivora (Koch) (Aphididae: Homoptera) is associated with many host plants in the family Fabaceae and also in many other plant families such that it attacks about 50 crops in 19 different plant families [2]. doi: 10.1006/meth.2001.1262, 41.

For neuropeptide GPCRs, besides high sequence similarity, all of the identified A. craccivora neuropeptide GPCRs have a one-to-one orthologous relationship with the homologs of A. pisum. A larger aphid colony was found to increase the benefit and decrease the cost of ant attendance. For example, the predicted 8 mature allatostatin A (AstA) peptides contain the C-terminal signature sequence of -Y/FXFGL/Iamide; adipokinetic hormone (AKH) has the sequence motif characterized by pQX6Wamide. The PTTH ortholog in A. pisum (ARM65502.1) also lacks the Cys residue at this position. doi: 10.1371/journal.pone.0130593, 40. Why were they not found? doi: 10.1016/S0960-9822(01)00068-9, 77.

It has also been reported that ILP5 is involved in embryonic development during wing differentiation in A. pisum (79). Most A. craccivora neuropeptides have highly conserved characteristic motifs within the same family. They are typically found in large numbers covering stems, leaf veins, and the underside of leaves. (2010) 8:e1000313. The predicted Proc of A. craccivora is identical to that of M. persicae with an N-terminal extension compared to the pentapeptide proctolin (RYLPT) of most other insects (42); the effect of this expansion on Proc biological activity remains unknown. Analyses of the barcode region indicated intraspecific and interspecific sequence divergences of 0.08 and 6.63%, respectively. It is speculated that this gene may be involved in the rapid development of aphids (10). G protein-coupled receptors in Anopheles gambiae. Identification and Characterization of Neuropeptides and Their G Protein-Coupled Receptors (GPCRs) in the Cowpea Aphid Aphis craccivora Discussion. Gutierrez et al. doi: 10.1093/nar/gkl161, 34.
