Insights into regulatory roles of MAPK-cascaded pathways in multiple stress responses and life cycles of insect and nematode mycopathogens
Fungal entomopathogenicity may have evolved at least 200 million years later than carnivorism of nematophagous fungi on Earth. This mini-review focuses on the composition and regulatory roles ofExpand

Daylight length‐dependent translocation of VIVID photoreceptor in cells and its essential role in conidiation and virulence of Beauveria bassiana
The fungal insect pathogen Beauveria bassiana has the blue-light photoreceptor VIVID (VVD) but lacks a pigmentation pattern to trace its light responses. Here, we show that the fungal vvd isExpand

Subcellular localization of five singular WSC domain-containing proteins and their roles in Beauveria bassiana responses to stress cues and metal ions.
Some model fungi have three or four proteins with each vectoring a single cell Wall Stress-responsive Component (WSC) domain at N-terminus. In this study, five proteins, each vectoring only a singleExpand

Two Photolyases Repair Distinct DNA Lesions and Reactivate UVB-Inactivated Conidia of an Insect Mycopathogen under Visible Light
Protecting fungal cells from damage from solar UVB irradiation is critical for development and application of fungal insecticides but is mechanistically not understood in Beauveria bassiana, aExpand

BrlA and AbaA Govern Virulence-Required Dimorphic Switch, Conidiation, and Pathogenicity in a Fungal Insect Pathogen
Dimorphic insect mycopathogens infect the host by hyphal penetration through the host cuticle and switch from the penetrating hyphae to unicellular blastospores after entry into the host hemocoel,Expand

Two histidine kinases can sense different stress cues for activation of the MAPK Hog1 in a fungal insect pathogen
Filamentous fungi possess a large family of histidine kinases (HKs) classified to 11 distinct groups. Of those, only Group III (HK3) homologues in some fungi can sense osmotic, fungicidal and/orExpand

Laboratory and field evaluations of camptothecin sodium salt against phytophagous mites.
BACKGROUND Camptothecin (CPT), a monoterpene indole alkaloid from Camptotheca acuminate (Nyssaceae), is toxic to some insect pests but insoluble in water. Here we show that an aqueous CPT-Na(+)Expand

A mixture of putative sodium salts of camptothecin and bamboo tar is a novel botanical insecticide against rice planthoppers and stem borers
The phytochemical camptothecin (CPT) from Camptotheca acuminate (Nyssaceae) and the byproduct bamboo tar (BT) from bamboo charcoal making are insoluble in water. Here, we prepared water-solubleExpand

C-terminal Ser/Thr residues are vital for the regulatory role of Ste7 in the asexual cycle and virulence of Beauveria bassiana
The mitogen-activated protein kinase (MAPK) kinase Ste7 has a conserved Ser/Thr loop (S/T-X4(6)-S/T) that can activate the MAPK Fus3 or Kss1 for the regulation of pheromone response and filamentousExpand

Pleiotropic effects of the histone deacetylase Hos2 linked to H4‐K16 deacetylation, H3‐K56 acetylation, and H2A‐S129 phosphorylation in Beauveria bassiana
Histone acetyltransferases and deacetylases maintain dynamics of lysine acetylation/deacetylation on histones and nonhistone substrates involved in gene regulation and cellular events. Hos2 is aExpand
