Novel genes and alleles of the BTB/POZ protein family in Oryza rufipogon.

The BTB/POZ family of proteins is widespread in plants and animals, playing important roles in development, growth, metabolism, and environmental responses. Although members of the expanded BTB/POZ gene family (OsBTB) have been identified in cultivated rice (Oryza sativa), their conservation, novelty, and potential applications for allele mining in O. rufipogon, the direct progenitor of O.

The transcription factor from tomato confers tolerance to drought stress in transgenic tobacco plants.

Unlabelled: Drought is a key environmental factor that restricts crop growth and productivity. Plant responses to water-deficit stress at the whole plant level are mediated by stress-response gene expression through the action of transcription factors (TF). The NAC (NAM/ATAF/CUC) transcription factor family has been well documented in its role in improving plant abiotic stress tolerance.
