Secondary ( -Proteobacteria) Endosymbionts Infect the Primary ( -Proteobacteria) Endosymbionts of Mealybugs Multiple Times and Coevolve with Their Hosts
Mealybugs (Hemiptera, Coccoidea, Pseudococcidae) are plant sap-sucking insects that have within their body cavities specialized cells containing prokaryotic primary endosymbionts (P-endosymbionts). The Pendosymbionts have the unusual property of containing within their cytoplasm prokaryotic secondary endosymbionts (S-endosymbionts) [C. D. von Dohlen, S. Kohler, S. T. Alsop, and W. R. McManus, N...
متن کاملEvolutionary relationships among primary 1 endosymbionts in the mealybug subfamily 2 Phenacoccinae ( Hemiptera : Coccoidea : 3 Pseudococcidae ) 4
13 Mealybugs (Coccoidea: Pseudococcidae) are sap-sucking plant parasites that harbor 14 bacterial endosymbionts within specialized organs. Previous studies have identified two 15 subfamilies, Pseudococcinae and Phenacoccinae, within mealybugs, and determined the 16 primary endosymbionts (P-endosymbionts) of the Pseudococcinae to be β Proteobacteria 17 (Candidatus Tremblaya princeps) containing ...
متن کاملThe genetic properties of the primary endosymbionts of mealybugs differ from those of other endosymbionts of plant sap-sucking insects.
Mealybugs (Hemiptera, Coccoidea, Pseudococcidae), like aphids and psyllids, are plant sap-sucking insects that have an obligate association with prokaryotic endosymbionts that are acquired through vertical, maternal transmission. We sequenced two fragments of the genome of Tremblaya princeps, the endosymbiont of mealybugs, which is a member of the beta subdivision of the Proteobacteria. Each of...
متن کاملCharacterization of Xenorhabdus (γ-Proteobacteria) strains associated bacteria with the Steinernema (Nematoda: Steinernematidae) isolates from Iran
باکتریهای Xenorhabdus همزیست اختصاصی نماتدهای بیمارگرحشرات در جنس Steinernema میباشند. در این بررسی مشخصات سه جدایهی باکتری جدا شده از دو گونه نماتد بیمارگر حشرات Steinernema glaseri (Steiner) وS. carpocapsae (Weiser) تعیین شده است. این دو گونهی بیمارگر از جمعیت طبیعی لاروهای کرم سفید ریشه، Polyphylla olivieri (Laporte de Castelnau)، جداسازی شدند. مطالعهی حاضر بر روی مشخصات اختصاصی این جدایههای...
متن کاملEvolutionary relationships of flavobacterial and enterobacterial endosymbionts with their scale insect hosts (Hemiptera: Coccoidea).
Flavobacteria and Enterobacteriaceae have been previously reported as scale insect endosymbionts. The purpose of this work was twofold: first, to screen different scale insect families for the presence of these endosymbionts by PCR analyses and second, to elucidate the history of cophylogeny between these bacteria and the insects by analysing a portion of 16S rRNA and 18S rRNA gene sequences by...
