This review highlights the latest advancements in the application of CRISPR/Cas9 technology for crop improvement and explores its potential in mitigating global food security. These advancements include the use of base and prime editing to accurately alter metabolic pathways for nutritional enhancements, along with designing Cas variants with limited dependency on PAM, to facilitate editing in complex genome crops like wheat. Moreover, the integration of artificial intelligence-driven target prediction and speed breeding has significantly improved varietal development by shortening breeding period and increasing resilience to various biotic and abiotic stresses.

They function as antimicrobial agents and signal molecules in response to pathogen attack. Structurally diverse groups—such as flavonoids, terpenoids, and alkaloids enable plants to mount broad-spectrum defences. Although natural phytoalexins are central and evolutionarily conserved components of plant defense, their rapid turnover, spatial restriction, and susceptibility to pathogen detoxification can sometimes limit duration or spectrum of protection, particularly under high disease pressure. Therefore, in addition to enhancing their biosynthesis and stability, targeted structural modifications enabled by molecular engineering may further optimize their activity and strengthen durable resistance in crops. Molecular engineering approaches, including transcription factor engineering, metabolic engineering, synthetic biology, CRISPR/Cas9 genome-editing, and epigenetic regulation, offer powerful tools to enhance phytoalexin biosynthesis and functionality. Emerging strategies aim to develop specialized phytoalexins with improved stability, potency, and a broader range of action. When integrated with modern breeding and biotechnological platforms, these molecular innovations can enhance crops resilience. Despite challenges such as metabolic trade-offs, and potential growth–defense imbalances, engineered phytoalexins represent a promising avenue for next-generation plant defense.

While traditional HI measurement methods use destructive field sampling, which is labour-intensive and impractical for large-scale breeding trials, recent advances in UAV-based remote sensing now offer non-destructive alternatives capable of delivering high-throughput, plot-level HI estimation. In this study, we present a high-throughput phenotyping framework that combines UAV-based multispectral imaging and ensemble machine learning to estimate HI under field environments. Multispectral data were collected at two key growth stages, anthesis and maturity, using a DJI M300 RTK drone equipped with a RedEdge-P sensor. Vegetation indices (VIs), including the normalized difference vegetation index (NDVI), normalized difference red edge index (NDRE), and green NDVI (G-NDVI), were extracted using data from sensors and ground truth monitoring and used as predictors to estimate grain yield and AGB for calculating HI. An ensemble learning model, based on a stacking architecture comprising five regressors and a ridge regression meta-learner, was employed to enhance prediction accuracy. Results showed strong correlations between UAV-derived and ground-truth VIs (<em>R</em><sup>2</sup> <em>&gt;</em> 0<em>.</em>94<em>,</em> RMSE <em>&lt;</em> 0<em>.</em>023). The ensemble model demonstrated high accuracy and strong generalization for HI estimation across both experimental sites and growing seasons. At the anthesis stage, the NDVI-based ensemble model achieved the best performance. For the Indian Head site, it yielded a testing <em>R</em><sup>2</sup> of 0.87, RMSE of 4.18 g/p, and NRMSE of 2.73 %, based on a training <em>R</em><sup>2</sup> of 0.83. At the Swift Current site, the model produced a testing <em>R</em><sup>2</sup> of 0.84, RMSE of 8.67 g/p, and NRMSE of 5.67 %. Similarly, at the maturity stage, the NDRE-based ensemble model was the top performer. It recorded a testing <em>R</em><sup>2</sup> of 0.86, RMSE of 7.10 g/p, and NRMSE of 4.64 % at Indian Head, and a testing <em>R</em><sup>2</sup> of 0.83 with an RMSE of 8.06 g/p, and NRMSE of 5.27 % at Swift Current. Across all indices and stages, the ensemble model consistently outperformed individual models, achieving high testing <em>R</em><sup>2</sup> values and low RMSE, which confirms its robustness and predictive power on unseen data. The proposed UAV machine learning framework demonstrates a reliable and non-destructive approach for field-level HI estimation, thereby improving germplasm selection efficiency for yield improvement.

The treatments included lanthanum (La) alone, dimethoate (LG1) alone, La+LG2, La+LG3, and La+LG4. Among them, the La+LG2 treatment exhibited the most superior performance. La+LG2 significantly enhanced plant growth, as evidenced by increases in plant height, fresh weight, and dry weight. It also reduced cell membrane damage, as indicated by lower malondialdehyde (MDA) levels and relative electrical conductivity. In terms of photosynthesis, La+LG2 elevated the P-phase fluorescence intensity of the OJIP curve, improved the maximum quantum yield of photosystem II (Fv/Fm), optimized the energy distribution within photosystem II (increasing electron transport flux per reaction center, ETO/RC, and trapped energy flux per reaction center, TRO/RC, while decreasing absorbed energy flux per reaction center, ABS/RC, and dissipated energy flux per reaction center, DIO/RC), and promoted pigment synthesis. Additionally, La+LG2 alleviated oxidative damage by activating enzymatic antioxidants, including superoxide dismutase (SOD), peroxidase (POD), catalase (CAT), and glutathione peroxidase (GSH-PX). It also optimized the ascorbic acid-glutathione (ASA-GSH) cycle to scavenge reactive oxygen species (ROS) and maintain redox homeostasis. Meanwhile, at the molecular level, La+LG2 constructed a dual-regulatory network to enhance photosynthetic efficiency and maintain the homeostasis of reactive oxygen species (ROS). This was accomplished via the synergistic activation of photosynthesis-related genes and the differential regulation of respiratory burst oxidase homolog (Rboh) family genes. Overall, La+LG2 achieved an efficacy comparable to that of high-dose LG1 but with reduced chemical input.

Using stereo- and scanning electron microscopy, we document the acropetal sequence of floral organ initiation and differentiation across four concentric whorls. Each stage is marked by distinct morphological features, starting with the domed floral meristem (Stage 1). Sepal primordia emerge first (Stage 2), followed by petal and stamen primordia (Stages 4 and 5), and two carpel primordia appear by Stage 6 to initiate gynoecium development. Through mid-development (Stages 6–8), petals and stamens expand within an enclosing calyx, while carpels remain unfused. By Stage 9, carpel fusion forms a single ovary with a differentiating stigma. Subsequent stages feature rapid elongation of petals and stamens, and partial calyx separation (Stages 11–12), allowing emergence of the corolla tube and style. Anthesis occurs at Stage 14, when the corolla lobes fully spread, exposing the mature reproductive organs. In parallel, we describe the coordinated development of male and female gametophytes, and further characterize post-anthesis fruit development, from fruit set through capsule maturation and dehiscence, thus completing the full reproductive cycle.
