Excessive production of reactive oxygen species (ROS) leads to potential toxicity in an organism. Class III peroxidases (PRXs) play important role maintaining ROS homeostasis plants. Internal browning (IB) limits industrial development pineapple, which is the third most fruit trade world. IB mainly caused by ROS, and mechanism underlying still unknown from perspective ROS. Here, we soaked pineapples ascorbic acid after harvest before storage decrease excessive polyphenol oxidase (PPO) activity, ultimately restraining spread deterioration IB. Using phylogenetic analysis; identified 78 pineapple PRX genes (AcPRXs) divided them into five subgroups. Gene structure analysis indicated that exon numbers ranged 2 14, conserved motif verified all AcPRXs here have standard peroxidase domains. Analysis duplication events suggested tandem segmental may played equal roles expanding AcPRX family. Comprehensive transcriptomic uncovered negatively regulating occurrence In summary, found scavenging delayed occurrence. The results characterized family revealed responded growth development, regulated stage. This research provides target for future in-depth molecular mechanisms contributes develop IB-resistant varieties.

APETALA2/ethylene response element-binding factor (AP2/ERF) transcription factors (TFs) have been found to regulate plant growth and development various abiotic stresses. However, detailed information of AP2/ERF genes in peanut against drought has not yet performed. Herein, 185 TF members were identified from the cultivated ( A. hypogaea cv. Tifrunner) genome, clustered into five subfamilies: AP2 (APETALA2), ERF (ethylene-responsive-element-binding), DREB (dehydration-responsive-element-binding), RAV (related ABI3/VP), Soloist (few unclassified factors)). Subsequently, phylogenetic relationship, intron–exon structure, chromosomal location AhAP2/ERF further characterized. All these distributed unevenly across 20 chromosomes, 14 tandem 85 segmental duplicated gene pairs which originated ancient duplication events. Gene evolution analysis showed that Tifrunner separated 64.07 66.44 Mya Medicago truncatula L. Glycine max L., respectively. Promoter discovered many cis -acting elements related light, hormones, tissues, stress responsiveness process. The protein interaction network predicted exitance functional among families or subgroups.

The APETALA2/ethylene-responsive element binding protein (AP2/ERF) is a highly conserved transcription factors family, involved in plant growth, development, and response to diverse stress conditions. Until recently, the AP2/ERF family has not been functionally characterized safflower. In total, 187 genes were identified from safflower genome. Phylogenetic analysis divided these CtAP2/ERFs into four distinct groups: DREB, ERFs, AP2s, RAV genes. Furthermore, motifs, gene structure, cis-regulatory elements suggested important evolutionary insights potential role of CtAP2/ERFs. Moreover, comprehensive expression conducted across various flowering stages demonstrated consistent pattern CtDREB52, which exhibited significant correlation with alterations total flavonoid content. Importantly, CtDREB52 was found be responsive UV-B stress, its overexpression only promoted accumulation but also induced an early phenotype up-regulated key pathway, while silencing showed opposite effect. Further, interaction between CtDFR CtMYB enzymes confirmed through yeast two-hybrid BiFC analysis. These findings provide CtDREB52-mediated regulation biosynthesis under by interacting

DELLA proteins are important repressors of gibberellin signaling, regulating plant development and defense responses through crosstalk with various phytohormones. Sugarcane ScGAI encodes a protein that regulates culm development. However, it is unclear which transcription factors mediate the ScGAI. Here, we identified two different promoter sequences cooperatively regulate transcription. We also nuclear-localized AP2 family factor, ScAIL1, inhibits by directly binding to promoters. ScAIL1 was expressed in all sugarcane tissues tested induced stressors, including NaCl, polyethylene glycol, pathogenic fungi bacteria. Overexpression rice significantly improved resistance bacterial blight blast, while reducing growth In addition, several genes associated stress were up-regulated transgenic overexpressing ScAIL1. Endogenous phytohormone content expression analysis further revealed ScAIL1-overexpressing lines blast instead promoting growth, this response increased jasmonic acid synthesis inactivation.
