MAP Kinase and Protein Kinase A–Dependent Mobilization of Triacylglycerol and Glycogen during Appressorium Turgor Generation by Magnaporthe grisea
Glycogen and lipid degradation were very rapid in a Δmac1 sum1-99 mutant, which carries a mutation in the regulatory subunit of PKA, occurring before appressorium morphogenesis was complete, indicating that mass transfer of storage carbohydrate and lipid reserves to the appressoria occurs under control of the PMK1 MAPK pathway.

The transcription factor Con7p is a central regulator of infection‐related morphogenesis in the rice blast fungus Magnaporthe grisea
Observations suggest that Con7p encodes a transcription factor required for the transcription of several genes which participate in disease‐related morphogenesis in M. grisea. Expand

  • 9 September 2011
Isolates resistant to five fungicides in vitro were capable of causing fruit rot on wounded apple pretreated with any one of the three commercially available products containing fenhexamid, pyraclostrobin plus boscalid, or cyprodinil plus fludioxonil, prompting question the sustainability of the current gray mold control strategy relying exclusively on fungicides with specific, single-site modes of action.

Gray Mold Populations in German Strawberry Fields Are Resistant to Multiple Fungicides and Dominated by a Novel Clade Closely Related to Botrytis cinerea
ABSTRACT The gray mold fungus Botrytis cinerea is a major threat to fruit and vegetable production. Strawberry fields usually receive several fungicide treatments against Botrytis per season. GrayExpand

A review of apple canker caused by Neonectria ditissima is presented for Northwestern Europe with a focus on the Lower Elbe region (Northern Germany). Whereas conidia released by rainsplash areExpand
Laetiporic acids, a family of non-carotenoid polyene pigments from fruit-bodies and liquid cultures of Laetiporus sulphureus (Polyporales, Fungi).
The non-isoprenoid polyene laetiporic acid A, recently described from fruit-bodies of the wood-rotting fungus Laetiporus sulphureus, was found to be the major orange pigment also in mycelium grown inExpand
A rapid and simple method for determining fungicide resistance in Botrytis
A simple test based on the germination of conidia of Botrytis on agar media augmented with various fungicides has been developed. Average concentrations causing a 50% reduction of germ-tube growthExpand
The vacuole as central element of the lytic system and sink for lipid droplets in maturing appressoria ofMagnaporthe grisea
It is envisaged that vacuoles are involved in the degradation of lipid storage reserves which may act as sources of energy and/or osmotically active metabolites such as glycerol, which generate the very high turgor pressure known to be crucial for penetration of hard surfaces. Expand
A New View of Sooty Blotch and Flyspeck.
The major shifts that have occurred during the past decade in understanding the genetic diversity of the SBFS complex are described, clarifying its biogeography and environmental biology, and developing improved management strategies. Expand
