A Network of Sporogenesis-Responsive Genes Regulates the Growth, Asexual Sporogenesis, Pathogenesis and Fusaric Acid Production of f. sp. .

The conidia produced by f. sp. (Foc), the causative agent of Fusarium Wilt of Banana (FWB), play central roles in the disease cycle, as the pathogen lacks a sexual reproduction process.

MoCpa1-mediated arginine biosynthesis is crucial for fungal growth, conidiation, and plant infection of Magnaporthe oryzae.

Arginine is an important amino acid involved in processes such as cell signal transduction, protein synthesis, and sexual reproduction. To understand the biological roles of arginine biosynthesis in pathogenic fungi, we used Cpa1, the carbamoyl phosphate synthase arginine-specific small chain subunit in Saccharomyces cerevisiae as a query to identify its ortholog in the Magnaporthe oryzae genome and named it MoCpa1. MoCpa1 is a 471-amino acid protein containing a CPSase_sm_chain domain and a GATase domain.

Flippases play specific but distinct roles in the development, pathogenicity, and secondary metabolism of Fusarium graminearum.

The membrane trafficking system is important for compartmentalization of the biosynthesis pathway and secretion of deoxynivalenol (DON) mycotoxin (a virulence factor) in Fusarium graminearum. Flippases are transmembrane lipid transporters and mediate a number of essential physiological steps of membrane trafficking, including vesicle budding, charging, and protein diffusion within the membrane. However, the roles of flippases in secondary metabolism remain unknown in filamentous fungi.

Fusarium oxysporum f. sp. lycopersici CH transcription factor FolCzf1 is required for conidiation, fusaric acid production, and early host infection.

The soil-borne, asexual fungus Fusarium oxysporum f.sp. lycopersici (Fol) is a causal agent of tomato wilt disease.

Novel technique for internal structure and elemental distribution analyses of granular sludge from reactors for wastewater treatment.

A novel technique for internal structure and elemental distribution analyses of granular sludge is presented. Sludge samples were freeze-dried and embedded in epoxy resin to form a module, which were then ground and polished to obtain sequential cross-sections. The cross-sections were analyzed by scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDX).

[Effects of soil surface mulching on the growth and physiological characteristics of grafted and non-grafted cucumbers in solar greenhouse].

This paper studied the effects of wheat straw mulching, plastic film mulching, and wheat straw plus plastic film mulching on the growth and physiological characteristics of grafted and non-grafted Cucumis sativus in solar greenhouse. The results showed that compared with the control, the plant height, stem diameter, photosynthetic rate, and root vitality of grafted C. sativus under wheat straw plus plastic film mulching, plastic film mulching, and wheat straw mulching were increased by 91, 71 and 57 cm, 0.
