Abstract
The present invention generally relates to the field of genetic engineering and obtaining transgenic traits for agronomic applications. More specifically, the present invention relates to a specific transgenic event in agricultural crops that improves plant characteristics. Yet more specifically, the invention relates to a polynucleotide construct comprising a gene from Arabidopsis thaliana. In particular, the polynucleotide construct of the invention comprises the gene AtBBX21 which encodes a B-box protein from Arabidopsis thaliana. The transgenic event of the invention increases green and seed yield, reduces photoinhibition, improves water use efficiency, increases tuber and chlorophyll production and improves photosynthetic rates, among others. The polynucleotide construct of the invention comprises a sequence depicted as SEQ ID NO: 1. The invention also provides a transgenic plant transformed with said polynucleotide construct, wherein said plant exhibits improved characteristics. In a particularly preferred embodiment, the transgenic plant is a potato (Solanum tuberosum) plant that overexpresses a gene from Arabidopsis thaliana, wherein said potato plant exhibits improved char…
