TTG2-regulated development is related to expression of putative AUXIN RESPONSE FACTOR genes in tobacco.

ABSTRACT:

Background

The phytohormone auxin mediates a stunning array of plant development through the functions of AUXIN RESPONSE FACTORs (ARFs), which belong to transcription factors and are present as a protein family comprising 10-43 members so far identified in different plant species. Plant development is also subject to regulation by TRANSPARENT TESTA GLABRA (TTG) proteins, such as NtTTG2 that we recently characterized in tobacco Nicotiana tabacum. To find the functional linkage between TTG and auxin in the regulation of plant development, we performed de novo assembly of the tobacco transcriptome to identify candidates of NtTTG2-regulated ARF genes.

Results

The role of NtTTG2 in tobacco growth and development was studied by analyzing the biological effects of gene silencing an
