Abstract

We determined the complete mitochondrial genome of the Japanese pine sawyer Monochamus alternatus Hope (Coleoptera: Cerambycidae), which is a major forest pest in Asia. The genome is 15,874 bp in length containing 37 typical animal mitochondrial genes and one non-coding A+T-rich region. Its gene content and order are typical of other coleopteran mitochondrial genomes described to date. All protein-coding genes (PCGs) are initiated by ATN codons. Eight PCGs use complete stop codons TAG or TAA, whereas other PCGs end with a single T. All tRNA genes show typical secondary cloverleaf structures except for tRNA(Ser(AGN)), which lacks the dihydrouridine (DHU) arm. The large non-coding A+T-rich region of 1249 bp contains a 14 bp-long poly-T stretch and two microsatellite-like (AT)(TA)7 and (TA)8 elements.

Pine wood nematode, Bursaphelenchus xylophilus.

K Futai (2012)

After devastating vast areas of pine forests in Asian countries, the pine wilt disease spread into European forests in 1999 and is causing worldwide concern. This disease involves very complicated interactions between a pathogenic nematode, its vector beetle, host pine species, and fungi in dead hosts. Pathogenicity of the pine wood nematode is determined not only by its physical and chemical traits but also by its behavioral traits. Most life history traits of the pine wood nematode, such as its phoretic relationship with vector beetles, seem to be more effective in virulent than in avirulent isolates or species. As the pathogenicity determinants, secreted enzymes, and surface coat proteins are very important, they have therefore been studied intensively. The mechanism of quick death of a large pine tree as a result of infection by a tiny nematode could be ascribed to the dysfunction of the water-conducting system caused by the death of parenchyma cells, which must have originally evolved as an inherent resistant system.

Interspecific communication between pinewood nematode, its insect vector, and associated microbes.

Jianghua Sun, Lilin Zhao, Manuel Mota … (2014)

Pine wilt disease (PWD) is perhaps the most serious threat to pine forests worldwide. The causative agent of PWD, the pinewood nematode (PWN), engages in a symbiotic partnership with its insect vector, the Monochamus beetle, as well as associated bacteria and ophiostomatoid fungi, in order to successfully infect and kill its host pine tree. This review focuses on the interspecific communication between PWN and its associated partners, and the potential role of this communication in promoting pathogenicity and invasiveness of PWN. We describe the chemical and molecular signals positively influencing the survival, reproduction, and spread of PWN. Knowledge of these signals could potentially be used to interfere with the proliferation and dispersal of PWN.
