Abstract
Homeodomain-leucine zippers (HD-Zip) are plant-specific transcription factors that participate in different plant development processes and differentially regulate metabolic processes. LoHDZ2 is an HD-ZipII subfamily transcription factor gene that we identified from a transcriptomic analysis of Larix olgensis. To understand its function, we built a LoHDZ2 expression vector and then inserted it into tobacco by genetic transformation. Transgenic plants were identified at the DNA and RNA levels. Phenotypic index analysis of transgenic tobacco showed dwarfed growth with larger leaves and earlier flowering than the wild type. LoHDZ2 was expressed differently after hormone treatment with IAA, MeJA and 2,4-D. The results suggested that LoHDZ2 may respond to hormones and be involved in regulating growth and metabolism. These results helped us better understand the function of LoHDZ2 and provided a candidate gene for Larix olgensis molecular breeding.
