Polyploidization is a common occurrence in the evolutionary history of flowering plants, significantly contributing to their adaptability and diversity. However, molecular mechanisms behind these adaptive advantages are not well understood. Through comprehensive phenotyping diploid tetraploid clones from Citrus Poncirus genera, we discovered that genome doubling enhances salt stress resilience. Epigenetic transcriptomic analyses revealed increased ethylene production roots plants was associated with hypomethylation enhanced chromatin accessibility ACO1 gene. This activates transcription reactive oxygen species scavenging genes stress-related hormone biosynthesis genes. Consequently, exhibited superior root functionality under stress, maintaining improved cytosolic K+/Na+ homeostasis. To genetically validate link between resilience expression, generated overexpression knockout lines, confirming central role expression regulation following Our work elucidates underlying We also highlight importance dynamics fine-tuning gene activating pathways, offering valuable insights into plant adaptation crop evolution.

Abstract Water is the basic molecule in living beings, and it has a major impact on vital processes. Plants are sessile organisms with sophisticated regulatory network that regulates how resources distributed between developmental adaptation Drought‐stressed plants can change their survival strategies to adapt this unfavorable situation. Indeed, modify, change, modulate gene expression when grown low‐water environment. This occurs through several mechanisms affect of genes, allowing these resist dry regions. Epigenetic modulation emerged as factor transcription regulation drought stress‐related genes. Moreover, specific molecular epigenetic modifications certain genetic networks lead adapted responses aid plant's acclimatization during repeated stress. understanding plant severe environmental stresses, including drought, critical for biotechnological applications. Here, we first focused stress general We also discussed exposed water be passed down generations.

Plants often encounter challenging environmental factors, including intense sunlight, drought, extreme heat, cold temperatures, salinity, excessive metals, and nutrient shortages, which can heavily affect their growth survival. In this regard, L-ascorbic acid (AsA) is not only an essential for human health but also plays a significant role in plant responses to stresses, regulating various functions during development, redox signaling, phytohormone biosynthesis. The growing need cope with climate change, together the advancement of CRISPR/Cas9-editing technologies, stimulated new opportunities enhance AsA biosynthesis improve crop stress tolerance. review, we discuss regulation abiotic response mechanisms. We explore latest advancements CRISPR/Cas9 applications, challenges as tools modifying genes associated metabolism, aiming develop crops more tolerant resilient changes.

To ameliorate plants’ response to environmental stresses, seed priming can be a useful tool; it consists of the pre-exposure seeds mild stress, which improves plant adaptation future exposure adverse growth conditions. In our previous studies, with polyamines (2.5 mM putrescine, 2.5 spermine, and spermidine) salt acclimation have been proven an effective treatment in enhancing tolerance tomato cultivars since they induced better physiological stressful condition. The persistence memory first (priming) stress retrieval such remembered information upon later new play important role applicability agriculture. Therefore, aim this work was detection by polyamine tomatoes. Primed not-primed were stored at +4 °C for 2 years after original treatment; then, germinated sown non-saline soil irrigated 80 160 NaCl solutions until fruit production. results confirm increase primed plants compared ones, indicating presence long-term somatic memory. comparison not primed, produced quality fruits, i.e., higher weight, water content, amount carotenoids, soluble sugars, phenols. determine if inherited offspring, then collected from (generation G1), further experiments undertaken growing G1 under same irrigation regime as parental generation. After 45 days growth, both antioxidants osmolyte amounts enhanced, leading improvement saline conditions offspring confirming already observed These demonstrate, time, intergenerational tomatoes may pave pathway agricultural application priming.

Phytosulfokine (PSK) is a tyrosine-sulfated pentapeptide found throughout the plant kingdom, playing key roles in growth, development, and responses to biotic abiotic stresses. However, there still lack of comprehensive analysis CsPSK gene family Camellia sinensis. In this study, we conducted genome-wide identification characterized 14 genes tea plants, which are unevenly distributed across seven chromosomes. encode proteins ranging from 75 124 amino acids length, all belonging PSK-α type containing conserved PSK domains. A synteny revealed that expansion primarily attributed whole-genome duplication, with homology Arabidopsis thaliana genes. promoter region identified cis-regulatory elements related hormone stress responses. An expression profile showed highly expressed roots, stems, flowers, leaves, induced by both Furthermore, an RT-qPCR assay demonstrated levels CsPSK8, CsPSK9, CsPSK10 significantly upregulated following Discula theae-sinensis infection. These findings establish basis for further research into role disease resistance underlying molecular mechanisms, offering valuable perspectives developing novel antimicrobial peptides.

As global warming progresses, quantifying drought thresholds for crop yield losses is crucial food security and sustainable agriculture. Based on the CNN-LSTM model Copula function, this study constructs a conditional probability framework under future climate change. It analyzes relationship between Standardized Precipitation–Evapotranspiration Index (SPEI) winter wheat yield, assesses vulnerability of in various regions to stress, quantifies The results showed that (1) SPEI Zhoukou, Sanmenxia, Nanyang was significantly correlated with yield; (2) southern eastern higher than center, western, northern past (2000–2023) (2024–2047); (3) there were significant differences thresholds. loss below 30, 50, 70 percentiles (past/future) −1.86/−2.47, −0.85/−1.39, 0.60/0.35 (Xinyang); −1.45/−2.16, −0.75/−1.34, −0.17/−0.43 (Nanyang); −1.47/−2.24, −0.97/−1.61, 0.69/0.28 (Zhoukou); −2.18/−2.86, −1.80/−2.36, −0.75/−1.08 (Kaifeng), indicating threshold will reduce future.
