The potential protein kinase A (Pka) phosphorylation site is required for the function of FgSge1 in Fusarium graminearum.

The new transcription factor Sge1 has garnered much attention in filamentous fungi recently, which highlights its role in pathogenicity, conidiation, and the production of secondary metabolites. In this study, we demonstrated that FgSge1 is localized in the nucleus in Fusarium graminearum using fluorescent protein GFP. Mutants containing a T67A mutation within the potential protein kinase A (Pka) phosphorylation site of FgSge1 exhibited a significant decrease in conidiation and dramatically impaired virulence on both wheat head and non-host tomato.

Up-regulation of integrin α6β4 expression by mitogens involved in dairy cow mammary development.

In dairy cows, the extracellular microenvironment varies significantly from the virgin state to lactation. The function of integrin α6β4 is dependent on cell type and extracellular microenvironment, and the precise expression profile of α6β4 and its effects on mammary development remain to be determined. In the present study, real-time PCR and immunohistochemistry were used to analyze the expression and localization of integrin α6β4 in Holstein dairy cow mammary glands.

[Application of thermal dissipation probe in the study of Bambusa chungii sap flow].

Based on the validation of Granier's empirical formula for calculating tree stem sap flux density, a comparative study was conducted on the measurement of Bambusa chungi sap flow by using different lengths of thermal dissipation probe (TDP), aimed to approach the applicability of TDP in measuring the sap flow of B. chungii. The difference in the daily change of the sap flow between B.

[Effects of tree diameter at breast height and soil moisture on transpiration of Schima superba based on sap flow pattern and normalization].

The eigenvalues of continuous sap flow pattern, i. e. , skewness and kurtosis, were used to investigate the water usage of Schima superba with different diameter at breast height (DBH), and the method of normalization was firstly applied to eliminate the effects of strong affecting factor (photosynthetic active radiation, PAR) to explore the possible relationship between weak affecting factor (soil moisture) and sap flow.
