Four more species may be occasional pests (Blackman and Eastop 1984, Stoetzel 1994). Dev Cell. Aphis craccivora colony was maintained on seedlings of fava bean in a growth chamber at 23°C with a photoperiod of 12: 12 (L: D) and 50% relative humidity. Introduction A. craccivora is a cosmopolitan species with a worldwide distribution; abundant in subtropical and tropical regions, and in the Mediterranean. Cowpea aphid, Black legume aphid, Groundnut aphid.. Distribution. A40 is the ortholog of D. melanogaster LGR2, which has been confirmed to be a receptor for Bursicon and is also the first deorphanized LGR in invertebrates (50, 51). Wei ZJ, Zhang QR, Kang L, Xu WH, Denlinger DL. 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. Four more species may be occasional pests (Blackman and Eastop 1984; Stoetzel 1994). Insect Biochem Mol Biol. Alert. Sulfinator (https://web.expasy.org/sulfinator/) was used to identify the sulfation of tyrosine residues (34). It feeds on the young shoots, leaves, flowers and fruits, and is strongly ant attended. doi: 10.1021/bi00185a031, 71. doi: 10.1016/j.ibmb.2015.03.008, 56. doi: 10.1016/j.cropro.2015.12.015, 18. Kamphuis LG(1), Gao L, Singh KB. NPF is homologous to the vertebrate neuropeptide Y (NPY) and its functional roles are well-known in regulation of feeding behavior in a wide range of insects (60). Front Endocrinol. We also found a unigene from the A. craccivora transcriptome that lacks the 5′-end of the ORF and may encode a partial sequence of the PTTH precursor. The sequencing results were compared with the corresponding unigene sequences using Blastn to determine sequence identity. Insect Biochem Mol Biol. (2005) 51:691–700. (2005) 102:2820–5. Three plant spacings (30 cm, 7.5 cm and 2.5 cm) within rows 90 cm apart, were used in three field trials. J Cell Biol. Aphis craccivora prefers plants in the Fabaceae (beans, peas and groundnuts), but it is highly polyphagous and has been found on many plant species. Compared to D. melanogaster, B. mori, and T. castaneum, we found neither the genes coding for SK, Crz, AVLP, trissin, and elevenin in A. craccivora nor the genes coding for their receptors. Scale bars at bottom show length in amino acids (aa). From the third instar, we were able to distinguish winged from wingless aphids by wing buds of the thorax. Data are presented as the mean ± SD. Insulin-related peptide 5 is involved in regulating embryo development and biochemical composition in pea aphid with wing polyphenism. Relative expression levels of neuropeptide-encoding genes at different developmental stages of A. craccivora. Cage evaluations of one variety indicated that aphid resistance could complement the activity of the coccinellid in reducing the population densities of Aphis craccivora and damage to infested plants. CARS-13), the Major Scientific and Technological Innovation Projects in Shandong Province (2019JZZY010702), and the Agricultural Scientific and Technological Innovation Project of Shandong Academy of Agricultural Sciences (CXGC2018E21). Peptides. Transmission failures and infection costs likely limit the spread of protective Hamiltonella defensa in Aphis craccivora. Al-Anzi B, Armand E, Nagamei P, Olszewski M, Sapin V, Waters C, et al. G protein coupled receptors as targets for next generation pesticides. Tanaka et al. However, whether the differential temporal expressions of these genes have a biological role on development needs further investigation. Aphis craccivora is a small species of aphid. SK, Crz, and AVLP neuropeptide signaling systems were found in another hemipteran insect, N. lugens, but the trissin signaling system was absent in this species (6). Identified by Raw identification qualifier Taxon identification issue Specimen type Original name usage. In: Geary TG, Maule AG, editor. Thus, it is speculated that A38 may be an insulin-like receptor. The phylogenetic trees were finally edited and displayed using FigTree 1.4.3 (http://tree.bio.ed.ac.uk/software/figtree). Nucleic Acids Res. Gen Comp Endocrinol. However, the position of Cys residues and the folding structure of dimers were highly conservative (69–72). We also carried out the expression profiling of genes encoding neuropeptides and their receptors in different developmental stages. Among them, only A40 has a complete ORF. Dorsum of abdomen pale, Cauda and siphunculi both dark: Spiraea aphid, Aphis spiraecola Patch: 3. 16. However, a small number of family members were missing, including CNMamide (CNMa), corazonin (Crz), elevenin, neuroparsin, pigment-dispersing factor (PDF), RYamide (RYa), sulfakinin (SK), sex peptide (SP), trissin, arginine vasopressin-like peptide (AVLP), and adipokinetic hormone/corazonin-related peptide (ACP). The proportion of alatae in Aphis craccivora was higher than in Acyrthosiphon pisum. Nässel DR, Zandawala M.

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). However, only one NPLP-encoding gene, NPLP1, was found in A. pisum (10). Copyright © 2020 Li, Du, Jiang, Ju, Qu, Qu and Liu. ... 27 results for SPECIES: Aphis (Aphis) craccivora placeholder. According to the structure characteristics, LGRs are divided into type A, type B, and type C. The main differences among the 3 types are the number of leucine-rich repeats (LRRs), the presence or absence of a low density lipoprotein receptor-like cysteine-rich (LDLa) motif, and type-specific hinge region (48, 49). This gene also encodes another polypeptide, EGLIAFPRIamide, which is identical to the CAPA-2 peptide of A. pisum and M. persicae (42, 44). Dorsum of abdomen pale, Cauda pale; Siphunculi dark. Date 2012. For the neuropeptide GPCRs, two receptor genes for LK, SIFa and NPF have been identified from A. craccivora, A. pisum, and N. lugens (Figure 2), suggesting that each of these receptor genes duplicated in the evolution. The majority of A. craccivora neuropeptide precursors showed more than 90% similarity with their homologous sequences in other aphids, whereas a few had low similarity with homologous sequences in related species, such as proctolin (Proc), leucokinin (LK), and diuretic hormone 44 (DH44).

One or several bioactive mature peptides are then formed through a series of enzymatic digestions and post-translational modifications, which are critical to ensure the biological activity and stability of mature neuropeptides (41). Some neuropeptide signaling systems are lost in specific species, possibly due to functional redundancy that occurs during adaptation and evolution or other neuropeptide signalings taking over their functions (3). Expression of neuropeptide F gene and its regulation of feeding behavior in the pea aphid, Acyrthosiphon pisum. Different lowercase letters indicate significant differences at the 0.05 level. Acyrthosiphon pisum has longer legs, higher walking speed, and stronger tolerance of starvation all of which favour dispersal by walking.
