Plastome data provides new insights into population differentiation and evolution of Ginkgo in the Sichuan Basin of China.

Background: Ginkgo biloba L., an iconic living fossil, challenges traditional views of evolutionary stasis. While nuclear genomic studies have revealed population structure across China, the evolutionary patterns reflected in maternally inherited plastomes remain unclear, particularly in the Sichuan Basin - a potential glacial refugium that may have played a crucial role in Ginkgo's persistence.

Identification and Characterization of Varieties Resistant to and Their Resistance Mechanisms.

, the city flower of Chengdu, is culturally significant and has nutritional and medicinal benefits. However, frequent infestations of have caused economic losses. This study aimed to identify insect-resistant varieties.

Transcription and Metabolic Profiling Analysis of Three Discolorations in a Day of .

In this study, we used combined transcriptomics and metabolomics to analyze the cultivar's genetic and physiological mechanisms during three flower color transition periods (from white to pink, then from pink to red) within the span of one day. As a result, 186 genes were found to be significantly increased with the deepening of the flower color; these genes were mainly involved in the expression of peroxidase 30, zinc finger protein, phosphate transporter PHO1, etc. In contrast, 298 genes were significantly downregulated with the deepening of flower color, including those involved in the expression of probable O-methyltransferase 3, copper binding protein 9, and heat stress transcription factor A-6b.
