ABSTRACT

Objective:

To analyze the sequence characteristics,chromosomal locationgene structure,conserved motifs,phylogenetic evolution and differential gene expressions of the <italic>Cannabis sativa</italic> YABBY transcription factor family,in order to provide a molecular basis for in-depth study of <italic>YABBY</italic> gene function and theoretical support for the selection and breeding of superior hemp varieties.

Method:

The bio-informatics method was used to identify and analyze the <italic>CsYABBY </italic>gene family of the original hemp seed plant. PlantTFDB,ExPASy,MEME,CELLO,PLANTCARE and other online websites and TBtools,MEGA,DNAMAN and other software were used for prediction,visualization and analysis.

Result:

<italic>C. sativa</italic> contains 6 <italic>YABBY</italic> gene members distributed on 5 chromosomes,in which 5 members are localized in the nucleus and 1 in extracellular, they consist of 185-235 amino acids, and the isoelectric point is between 5.05 and 9.34, the molecular weight is between 20 582.45-26 282.7 Da. All of CsYABBY proteins contain two conserved domains, namely Zinc finger domain and YABBY domain. <italic>CsYABBY</italic> genes have multiple cis-acting elements,and their expressions differ in different tissues and cultivars.

Conclusion:

The expressions of CsYABBY may be affected by hormones and externally environmental factors. <italic>CsYABBY</italic> gene expressions are tissue-specific. In addition,YABBY transcription factor family may play an important role in regulating the development of <italic>C. sativa</italic> female flowers,and subfamilies YAB1 and YAB5 may be involved in the synthesis of cannabinoids.
