    Abstract Magnolia officinalis is a perennial deciduous tree that has medicinal properties. The AP2/ERF gene family has a number of roles in long-term growth and metabolism. The expression of this function varies with the growth period. In this work, based on the transcriptome data of Magnolia officinalis, the complete coding gene of Magnolia officinalis was obtained, and the corresponding protein sequence was retrieved from NCBI and compared with the model plant Arabidopsis thaliana. After screening, 75 protein sequences from the AP2/ERF gene family were identified and called MoAP2/ERF1MoAP2/ERF75, followed by bioinformatics analysis. 75 AP2/ERF gene families were found and classified into four… More >

    Phyton-International Journal of Experimental Botany, Vol.92, No.7, pp. 1987-1999, 2023, DOI:10.32604/phyton.2023.027318 - 29 May 2023

    Abstract Phytophthora nicotianae causes substantial economic losses in most countries where tobacco is produced. At present, the control of P. nicotianae mainly depends on chemical methods, with considerable environmental and health issues. We investigated the effects of ethanol extracts from Scutellaria baicalensis Georgi (SBG) and Magnolia officinalis (MO). On mycelial growth, sporangium formation, and zoospore release of P. nicotianae. Both extracts inhibited the growth of P. nicotianae, with mycelial growth inhibition rates of 88.92% and 93.92%, respectively, at 40 mg/mL, and EC50 values of 5.39 and 5.74 mg/mL, respectively. The underlying mechanisms were the inhibition of sporangium formation, the reduction of zoospore More >
