Ectopic expression of NAC transcription factor HaNAC3 from Haloxylon ammodendron increased abiotic stress resistance in tobacco.

However, the chemical properties of NAC transcription factors in the desert plant Haloxylon ammodendron are also uncertain. The NAC transcription factor HaNAC3 was isolated and cloned from a common desert plant H. ammodendron, and its potential biological functions were investigated in this research. According to a Bioinformatics review, HaNAC3 has the unique NAC structural domain of the NAC transcription factor. The GFP-HaNAC3 fusion protein was localized in the nucleus of tobacco epidermal cells, according to a subcellular localization study. HaNAC3 had transcriptional self-activation activity, according to a transcriptional auto-activation assay, and the transcriptional activation site was located at the C-terminus, according to the transcriptional self-activation assay. The results showed that transgenic tobacco was more resistant to abiotic stresses than wild-type B. fuminata. These findings indicate that HaNAC3 may play a stress resistance role in H. ammodendron and has potential applications in plant molecular breeding.

MIKC-type MADS-box transcription factor gene family in peanut: Genome-wide characterization and expression analysis under abiotic stress.

Plant growth and development are also linked to plant growth and development, as well as responses to abiotic stresses, which are largely controlled by MADS-box transcription factors. Consequently, 166 MIKC-type MADS-box genes were found in both cultivated and wild-type peanut genomes, which were divided into 12 subfamilies, according to this review. The chromosomal distribution of peanut MADS-box genes was not random, and gene duplication contributed to the expansion of the MADS-box gene family. The peanut AhMADS proteins were first introduced in a network. AhMADS genes were specifically expressed in tissues and under abiotic stress, according to a quantitative expression pattern analysis.
