Abstract:

ABSTRACT The nitrogen assimilation control protein (NAC) is a LysR-type transcriptional regulator (LTTR) that is made under conditions of nitrogen-limited growth. NAC's synthesis is entirely dependent on phosphorylated NtrC from the two-component Ntr system and requires the unusual sigma factor σ54 for transcription of the nac gene. NAC activates the transcription of σ70-dependent genes whose products provide the cell with ammonia or glutamate. NAC represses genes whose products use ammonia and also represses its own transcription. In addition, NAC also subtly adjusts other cellular functions

Abstract:

NAC transcription factors play a significant role in plant stress responses. In this study, an NAC transcription factor, with a CDS of 792 bp encoding 263 amino acids, was cloned from Fagopyrum tataricum (L.) Gaertn. (F. tataricum), a minor cereal crop, which is rich in flavonoids and highly stress resistant. The transcription factor was named FtNAC10 (NCBI accession number: MK614506.1) and characterized as a member of the NAP subgroup of NAC transcriptions factors. The gene exhibited a highly conserved N-terminal, encoding about 150 amino acids, and a highly specific C-terminal. The resulting

ABSTRACT The nitrogen assimilation control protein (NAC) fromKlebsiella aerogenes or Escherichia coli(NACK or NACE, respectively) is a transcriptional regulator that is both necessary and sufficient to activate transcription of the histidine utilization (hut) operon and to repress transcription of the glutamate dehydrogenase (gdh) operon in K. aerogenes. Truncated NAC polypeptides, generated by the introduction of stop codons within thenac open reading frame, were tested for the ability to activate hut and repress gdh in vivo.

Abstract:

AbstractClimate change, malnutrition, and food insecurity are the inevitable challenges being faced by the agriculture sector today. Plants are susceptible to extreme temperatures during the crucial phases of flowering and seed development, and elevated carbon levels also lead to yield losses. Productivity is also affected by floods and droughts. Therefore, increasing plant yield and stress tolerance are the priorities to be met through novel biotechnological interventions. The contributions of NAC genes towards enhancing plant survivability under stress is well known. Here we focus on the pot

Abstract:

Banana (Musa acuminata, AAA group) is a representative climacteric fruit with essential nutrients and pleasant flavors. Control of its ripening determines both the fruit quality and the shelf life. NAC (NAM, ATAF, CUC2) proteins, as one of the largest superfamilies of transcription factors, play crucial roles in various functions, especially developmental processes. Thus, it is important to conduct a comprehensive identification and characterization of the NAC transcription factor family at the genomic level in M. acuminata. In this article, a total of 181 banana NAC genes were identified. Phy

Abstract:

Soil salinity greatly impacts the planting area of cultivated peanut. It is necessary to breed salt-tolerant cultivars. However, few salt-resistant genes have been identified in peanut. Here, we reported the cloning of a peanut NAC transcription factor gene, AhNAPa, which was expressed ubiquitously and significantly upregulated after salt treatment. Furthermore, an AhNAPa-GFP fusion protein was found to be located in the nucleus, which indicated that AhNAPa might perform functions as a transcriptional activator in peanut. Under NaCl treatment, Arabidopsis plants overexpressing AhNAPa (AhNAPa-O

These proteins were divided into 19 subfamilies based on their phylogenetic relationship, motif pattern, and gene structure analysis. Expression analysis with RNA-seq revealed that most HhNACs were expressed in response to drought and salt stress. Research of quantitative real-time PCR analysis of nine selected HhNACs supported

Rose is one of the most popular ornamental plants worldwide. The double-flower trait, referring to flowers with extra petals, has been a key focus in rose breeding history. However, the genetic mechanisms regulating petal number in roses are still not fully understood.

The expression of RhCUC3 was high during the petal and stamen primordium differentiation stages but declined sharply during pistil primordium development.

Abstract:

The frequent occurrence of excessive heat events driven by global warming poses a great threat to plant growth and food security. To survive in heat stress (HS) environments, plants have evolved sophisticated response mechanisms, and the transcriptional network that controls the expression levels of HS-inducible genes serves as an essential component of this process. NAC (NAM, ATAF1/2, and CUC2) transcription factors (TFs) play key regulatory roles in the abiotic stress responses of plants. However, the functional roles of NAC TFs in the heat stress response of Chinese cabbage remain elusive.
