Spore morphology of New Zealand Azolla filiculoides Lam. (Salviniaceae) [PDF]

, 1993
Sporocarps, megaspores, and micro- spores of Azolla filiculoides are described from fresh fertile material from the South Island of New Zealand. Size estimates are given along with light and scanning electron microscope photographs. A brief discussion of

Effect of Endophytic Fungi on Thrips tabaci Development and Population Dynamics

Journal of Applied Entomology, EarlyView.
ABSTRACT Endophytic fungi are promising biocontrol agents because they colonise healthy plant tissues asymptomatically while inducing systemic resistance that negatively affects herbivorous insects. We investigated whether treatments with the endophytes Trichoderma harzianum and Beauveria bassiana in two onion cultivars (Allium cepa L.; Sturon and Red ...

Mfd deficiency decreases the abundance of complete transcripts of sporulation genes and alters sporogenesis and the structure of dormant Bacillus subtilis spores

Frontiers in Microbiology
Sporulation is a survival mechanism employed by Firmicutes, including Bacillus subtilis, when facing stressful conditions of growth (e.g., starvation). In this bacterium, the transcription repair coupling factor, Mfd, has been shown to play pivotal roles

Temperature, Disinfectant Concentration and Bacterial Innate Properties Influence the Disinfection of Bacterial Pathogens Relevant to Catfish Aquaculture

Journal of Fish Diseases, EarlyView.
ABSTRACT Aquaculture systems suffer a wide range of losses, mostly due to bacterial disease outbreaks, and the use of disinfectants is a routine practice for controlling the spread of pathogenic organisms globally. Including Aeromonas hydrophila, Streptococcus agalactiae and Edwardsiella tarda, implicated for natural disease outbreaks and economic ...

The phylogeny and morphological evolution of the fungal spore-feeding thrips, Idolothripinae (Thysanoptera: Phlaeothripidae) [PDF]

, 2016
This thesis is the most comprehensive phylogenetic study on the fungal spore-feeding thrips in over three decades since its last systematics framework was published in year 1983.

Innovative Field Applications of Probiotics, Prebiotics, and Medicinal Plant Products for Disease Control in Aquaculture

Journal of Fish Diseases, EarlyView.
ABSTRACT Disease outbreaks and the associated reliance on antibiotics pose major constraints to the sustainability of modern aquaculture. As regulatory pressures increase and consumer demand shifts toward residue‐free production, diverse biological interventions are gaining prominence as viable alternatives to chemotherapeutics.

Challenging Host Specificity: Malacosporean Parasite Dynamics—Tetracapsuloides bryosalmonae Beyond Salmonids—An Infection Experiment

Journal of Fish Diseases, EarlyView.
ABSTRACT Proliferative Kidney Disease (PKD) is a severe parasitic disease of salmonids caused by the malacosporean endoparasite Tetracapsuloides bryosalmonae. In the fish intermediate host, the parasite is disseminated via the circulatory system and ultimately reaches the kidney, where it matures before releasing infective spores into the environment ...

Coniferyl aldehyde from the phenylpropanoid pathway targets pyruvate kinase in Dactylobotrys graminicola to confer sheath rot resistance in hulless barley

Journal of Integrative Plant Biology, EarlyView.
Hulless barley resists the newly identified sheath rot disease caused by the necrotrophic fungal pathogen Dactylobotrys graminicola by releasing coniferyl aldehyde, a natural compound that disrupts energy production in the fungus. ABSTRACT Dactylobotrys graminicola (Dgr), a necrotrophic fungal pathogen, has recently been identified as the causative ...

ATXR5 and ATXR6 restrict meiotic crossover formation within heterochromatin in Arabidopsis

Journal of Integrative Plant Biology, EarlyView.
The Arabidopsis H3K27 mono‐methyltransferases ATXR5 and ATXR6 repress crossovers within meiotic heterochromatin, are required for heterochromatin condensation and H3K27me1 establishment, and specifically influence the maintenance of DNA methylation in meiocytes.
