Overexpression of Hybrid in Leads to Excessive Chlorophyll Synthesis and Improved Growth.

Chloroplasts is the site for photosynthesis, which is the main primary source of energy for plants. Golden2-like (GLK) is a key transcription factor that regulates chloroplast development and chlorophyll synthesis. However, most studies on genes are performed in crops and model plants with less attention to woody plants.

Physiological and transcriptomic analysis revealed that the accumulation of reactive oxygen species caused the low temperature sensitivity of Liriodendron × sinoamericanum.

Liriodendron × sinoamericanum is widely cultivated in southern China as an excellent wood and garden ornamental trees. However, its intolerance to low temperature limits its application to high latitudes. Understanding the molecular mechanism of low temperature sensitivity of Liriodendron × sinoamericanum is very important for its further application.

Gibberellin Oxidase Gene Family in : Genome-Wide Identification and Gene Expression Analysis.

GAox is a key enzyme for the transformation of gibberellins, and belongs to the 2-ketoglutarate dependent dioxygenase gene family (2ODD). However, a systematic analysis of in the angiosperm has not yet been reported. Here, we identified all gene family members in , which were classified into the three subgroups of , , and .
