Abstract:
... Batrachochytrium dendrobatidis (Bd), which causes chytridiomycosis, mainly infects Anura and Caudata but is poorly known in Gymnophiona. We conducted a survey of Bd in the Yunnan caecilian (Ichthyophis bannanicus) and found that 6 of 71 samples (8.4%) tested positive for Bd. To our knowledge, this is the first detection of Bd in wild I. bannanicus. ...

Several meq gene sequences from these outbreaks were amplified and molecularly characterised. 2. The meq protein sequences revealed three different sizes, namely the standard 339 aa, a shorter form of 338 aa lacking a proline residue at positio ...

Abstract:
... Plant induced defenses may benefit plants by increasing cannibalism among insect herbivores. However, the general efficacy of plant defenses that promote cannibalism remains unclear. Using a generalist Lepidopteran herbivore (Helicoverpa zea), we examined whether plant induced defenses in Solanum lycopersicum increased cannibalism among H. zea and whether defense-mediated cannibalism benefits both ...

Key features of S. sclerotiorum include its extraordinary host range, preference for dicotyledonous plants, relatively slow evolution, and production of protein effectors that are active in multiple host species. Plant resistance to this pathogen is highly com ...

To investigate the disease cause, a potential pathogenic fungus was isolated from melanized lesions of P. vannamei suffering from the BSD syndrome. The fungal isolate was then identified as Fusarium solani based on TEF1α and ITS-gene sequences. The ...
