Gestational hypertension and preeclampsia are frequently encountered conditions in pregnancy, often occurring around the time of delivery. Mild cases of these conditions in the near term typically result in few complications for both the mother and the newborn. However, women diagnosed with gestational hypertension or preeclampsia need careful monitoring of both maternal and fetal well-being throughout pregnancy, and those with severe symptoms should receive hospital- based management.

Nanotechnology offers the potential to provide innovative solutions for sustainable crop production as plants are exposed to a combination of climate change factors (CO, temperature, UV radiation, ozone), abiotic (heavy metals, salinity, drought), and biotic (virus, bacteria, fungi, nematode, and insects) stresses. The application of particular sizes, shapes, and concentration of nanomaterials (NMs) potentially mitigate the negative impacts in plants by modulation of photosynthetic rate, redox homeostasis, hormonal balance, and nutrient assimilation through upregulation of anti-stress metabolites, antioxidant defense pathways, and genes and genes network. The present review inculcates recent advances in uptake, translocation, and accumulation mechanisms of NMs in plants.

Article Synopsis
  • Fusarium wilt, particularly caused by the pathogen Foc4, is a major threat to banana crops in Asia, affecting both resistant and susceptible varieties.
  • A comparison of the transcriptome and metabolome profiles of banana roots revealed a significant difference in gene expression, with the resistant variety (G9) showing 1,856 differentially expressed genes compared to the susceptible variety (G1), which had only 172.
  • Key findings suggest that specific genes and metabolic processes, especially related to lipid metabolism and the regulation of resistance, play crucial roles in how different banana varieties respond to Foc4, aiding future breeding efforts for disease-resistant bananas.
