Genome-wide characterization and analysis of Golden 2-Like transcription factors related to leaf chlorophyll synthesis in diploid and triploid .

Golden 2-Like () transcription factors play a crucial role in chloroplast development and chlorophyll synthesis in many plant taxa. To date, no systematic analysis of transcription factors in tree species has been conducted. In this study, 40 genes in the genome were identified and divided into seven groups based on the gene structure and motif composition.

First Report of Powdery Mildew in Eucalyptus Caused by Erysiphe neolycopersici in China.

Eucalyptus is one of the most fast-growing and widely planted hardwood trees in the tropical and subtropical regions (Grattapaglia and Kirst, 2008). In December 2021, powdery mildew diseases were observed on the , × , × , and trees growing in the Eucalyptus garden of the Guangxi University campus in Nanning (108°22'E, 22°48'N) of Guangxi Zhuang Autonomous Region, where is the main plantation area for Eucalyptus. The spread of this disease would bring potential challenges on the Eucalyptus plantation management in this region of China.

Induction and Characterization of Tetraploid Through Zygotic Chromosome Doubling in .

Improvements in plant growth can bring great benefits to the forest industry. is an important plantation species worldwide, and given that ploidy increases are often associated with plant phenotype changes, it was reasoned that its polyploidization may have good prospects and great significance toward its cultivation. In this study, the zygotic development period of was observed through paraffin sections, and a correlation between the development time of flower buds after pollination and the zygotic development period was established.
