Identification of the BBX gene family in blueberry at different chromosome ploidy levels and fruit development and response under stress.

ABSTRACT:

Background

Blueberry (Vaccinium spp.) fruits are rich in flavonoids such as anthocyanins and have a high nutritional value. The zinc finger protein transcription factor B-box (BBX) plays important roles in plant growth and development, hormone response, abiotic stress, and anthocyanin accumulation. However, studies on the BBX family in blueberry are lacking.

Results

In total, 83 VcBBX and 24 VdBBX genes were identified in tetraploid and diploid blueberry, respectively. A correlation was observed between the number of BBX genes in blueberry and chromosome ploidy. Gene loss and specific replication during blueberry evolution may lead to an imbalance of quantitative relationship between VcBBX and VdBBX genes. The analysis of transcriptome and quantitative reverse transcription-
