Legume-infecting phytoplasmas identified in symptomatic tree medic (Medicago arborea), lucerne (M. sativa) and pigeonpea (Cajanus cajan) growing at a single trial site at Urrbrae, South Australia, were all shown to belong to the 16SrII phytoplasma taxonomic group, but each host species was found to be infected with a different genotype. Within one species (M. sativa) the genotypes were more uniform as demonstrated by comparing five isolates from lucerne plots. These lucerne genotypes differed from the Australian lucerne yellows phytoplasma genotype previously described in New South Wales, and the pigeonpea phytoplasma isolate was more similar to the non-legume infecting Bonamia little leaf (BoLL) than to pigeonpea little leaf phytoplasma. This diversity supports the view that these legumes were infected from different reservoir phytoplasma hosts rather than from a single perennial host such as tree medic. © 2013 Australasian Plant Pathology Society Inc.

Kalmusia ebuli, the type species of Kalmusia, lacks type material and therefore its phylogenetic position remains unresolved. As a consequence the familial position of Kalmusia is based on morphology and molecular phylogeny of species other than the type. A fresh collection of K. ebuli, recently obtained from decorticated wood of Populus tremula in the foothills of the French Pyrenees is, therefore, designated as neotype to stabilize the application of the species and/or genus name. The holotype of K. ebuli f. sarothamni represents a synonym of K. ebuli. The genus Kalmusia is shown to be polyphyletic within the family Montagnulaceae, with K. ebuli being distant from K. brevispora and K. scabrispora, which appear to represent a different genus. © 2014 Magnolia Press.

The bluish yellow lappet moth, Trabala vishnou guttata is an extraordinarily important pest in China. The complete mitochondrial genome is sequenced and determined firstly, which is based on traditional PCR amplification and primer walking methods with a length of 15,281 bp, including 13 protein-coding (PCG) genes, 22 transfer RNA (rRNA) genes, two ribosomal RNA (tRNA) genes, and an A + T-rich region. The gene order and orientation of the T. vishnou guttata mitogenome were identical to the other sequenced Lasiocampidae species. The overall nucleotide composition of T. vishnou guttata is A (40.27 %), T (40.59 %), C (11.58 %) and G (7.56 %), respectively. All the PCGs initiate with the three orthodox start codons ATN except for coxI with CGA start codon. Three PCGs (coxI, coxII and nad4) used incomplete stop codon T, while the other 10 PCGs terminate with complete stop codon TAA. All tRNA genes have a typical clover-leaf structure except for the absence of a dihydrouridine arm in trnS (AGN). The length of A + T-rich region is 383 bp. Phylogeny is established to reveal the genetic relationship between T. vishnou guttata and other lepidopteran species based on 13 PCGs nucleotide sequences of the sequenced species (32 taxa) by Maximum likelihood and Bayesian methods. Phylogenetic analyses presents that T. vishnou guttata and its closely related species (Dendrolimus taxa) are clustered on Lasiocampidae group. It is a sister clade relationship between Lasiocampidae and other families in Bombycoidea with a bootstrap value of 83 % and a posterior probability of 0.75. This study supports that Lasiocampidae may be independent from Bombycoidea. © 2016 Springer International Publishing Switzerland

A new species of Helicascus (H. gallicus) is described and illustrated from submerged wood collected from aquatic habitats in western and southern France. It is morphologically characterized by multilocular ascomata covered by a thick clypeus and sharing a common ostiole, clavate asci with endoascus coiling in the pedicel, cellular pseudoparaphyses, and brown 2- celled ascospores with a marked submedian septum. Its relationships with other species of Helicascus are discussed based on morphology and 28S and ITS nrDNA sequence comparisons. © 2014 Magnolia Press.

Basal stem rot caused by Ganoderma boninense is the most serious disease of oil palm in virtually all growing regions in South East Asia and listed as among the key challenges for this major oil crop. Plant pathogenesis related proteins and in particular PR peptides are an integral part of the activation of plant defense responses against fungal infection in plant cells and PR10 and Lipid Transfer Protein LTP are two such proteins whose expressions are affected by exposure to different stress conditions including fungal infection. Degenerate primer pair combinations for conserved amino acid regions based on LTP and PR10 gene sequences from model plants were used to amplify Oil Palm LTP sequences (EgLTP) showing similarities of up to 100% with rice, while for EgPR10 the similarities were similarly up to 100% with wheat. Significantly, the expression of both EgPR10 and EgLTP genes measured using Q-PCR in infected oil palm were temporally down regulated during the early stages of infection suggesting that down regulation of the both are related to the establishment of infection. Consequently these genes could be used as early indicators of invasion before the onset of symptoms and in breeding programmes for early selection of the elusive resistant palms. © 2014 University of Agriculture.

Basal stem rot is a common disease that affects oil palm, causing loss of yield and finally killing the trees. The disease, caused by fungus Ganoderma boninense, devastates thousands of hectares of oil palm plantings in Southeast Asia every year. In the present study, root proteins of healthy oil palm seedlings, and those infected with G. boninense, were analyzed by 2-dimensional gel electrophoresis (2-DE). When the 2-DE profiles were analyzed for proteins, which exhibit consistent significant change of abundance upon infection with G. boninense, 21 passed our screening criteria. Subsequent analyses by mass spectrometry and database search identified caffeoyl-CoA O-methyltransferase, caffeic acid O-methyltransferase, enolase, fructokinase, cysteine synthase, malate dehydrogenase, and ATP synthase as among proteins of which abundances were markedly altered. © 2014 by the authors; licensee MDPI, Basel, Switzerland.

A new species of Venturia (V. chinensis) is described and illustrated from the leaves of Lonicera praeflorens collected from Lesser Khingan Mountains, the northeast China. It is characterized by habitat saprobic; ascomata small-sized, solitary or scattered, superficial, subglobose to citriform, wall black, papillate, ostiolate, covered with setae; peridium thin; hamathecium evanescent in mature ascomata; asci 8-spored, bitunicate, fissitunicate, oblong to obclavate, with or without a short, knob-like pedicel; ascospores ellipsoidal, olivaceous pale brown, 1-septate, ascospore wall thin, smooth. Comparisons of V. chinensis with V. lonicerae (another species on Lonicera caerulea) and other species of Venturia lead to the conclusion that collected taxon is new. Its relationships with other species of Venturia are discussed based on morphology and 28S nrDNA and ITS nrDNA sequence comparisons. © 2015 The Authors.

A new Botryosphaeria species (B. sinensia) is described and illustrated from China. It is characterized by erumpent, botryose clustered ascostromata, ostiolate ascomata, bitunicate, 8-spored and clavate asci, filiform, rarely branched pseudoparaphyses, hyaline, 1-celled, fusiform ascospores, and a Fusicoccum asexual morph. The hyaline old and discharged conidia with 1-2 septa, broader spermatia formed in the culture and smaller ascostroma readily distinguished it from B. dothidea and other species in Botryosphaeria. The intergenic spacer (ITS) and translation elongation factor 1-alpha (EF1) DNA sequence analysis results also support its separation from other Botryosphaeria species. Its relationships with other species of Botryosphaeria are also discussed based on morphology and DNA sequence comparisons. © 2016 Magnolia Press.
