Abstract

Crop plants should be resilient to climatic factors in order to feed ever-increasing populations. Plants have developed stress-responsive mechanisms by changing their metabolic pathways and switching the stress-responsive genes. The discovery of plant transcriptional factors (TFs), as key regulators of different biotic and abiotic stresses, has opened up new horizons for plant scientists. TFs perceive the signal and switch certain stress-responsive genes on and off by binding to different cis-regulatory elements. More than 50 families of plant TFs have been reported in nature. Among them, DREB, bZIP, MYB, NAC, Zinc-finger, HSF, Dof, WRKY, and NF-Y are important with respect to biotic and abiotic stresses, but the potential of many TFs in the improvement of crops is untapped. In this review, we summarize the role of different stress-responsive TFs with respect to biotic and abiotic stresses. Further, challenges and future opportunities linked with TFs for developing climate-resilient crops are also elaborated.

  • Integrating multi-omics strategies-genomics, proteomics, and phenomics-improves the efficiency of breeding programs aimed at generating climate-resilient crops.

    “Moreover, a comprehensive approach that integrates multi-omics strategies—combining genomics, proteomics, and phenomics—has been emphasized to improve the efficiency of breeding programs aimed at generating climate-resilient crops.”

    From Emerging applications of gene editing technologies for the development of climate-resilient crops (2025) · cites this paper as Shahzad et al., 2021

    The Conclusions and Future perspectives sections advocate genomic studies and breeding tools for climate-resilient crops. Crop improvement techniques and TFs says marker-assisted approaches can save time and labor. The paper does not, however, emphasize integrating genomics, proteomics, and phenomics as a strategy for improving breeding efficiency (searched: multi-omics, proteomics, phenomics). (LLM, conf=0.78)

  • Multi-omics integration allows better understanding of plant responses to abiotic stresses and facilitates identification of novel genetic targets for editing.

    “This integration allows for a better understanding of plant responses to abiotic stresses and facilitates the identification of novel genetic targets for editing (Ndlovu, 2020; Shahzad et al., 2021).”

    From Emerging applications of gene editing technologies for the development of climate-resilient crops (2025) · cites this paper as Shahzad et al., 2021

    The Conclusions (page not available) say genome-wide studies of transcription factors have clarified plant stress responses and identified key stress-responsive genes. Future perspectives (page not available) says bioinformatics analysis can identify proteins for targeting with genome-editing tools. The paper does not establish that *multi-omics integration* produces those benefits, so the claimed mechanism is unsupported. (LLM, conf=0.84)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
