SUMMARY Current climate change brings with it a higher frequency of environmental stresses, which occur in combination rather than individually leading to massive crop losses worldwide. In addition to, for example, drought stress (low water availability), also flooding (excessive water) can threaten the plant, causing, among others, an energy crisis due hypoxia, is responded by extensive transcriptional, metabolic and growth‐related adaptations. While signalling during relatively well understood, at least model plants, molecular mechanisms combinatorial responses, simultaneously salinity, temperature heavy metal or sequentially stress, remain elusive. This represents significant gap knowledge fact that dually stressed plants often show unique responses multiple levels not observed under single stress. this review, we (i) consider possible effects combinations from theoretical point view, (ii) summarize current state on signal transduction (iii) describe plant adaptation combined four other abiotic stresses (iv) propose components (hypoxia) based their reported dual roles stresses. way, more future emphasis may be placed deciphering adaptation, thereby potentially stimulating development tools improve resilience towards multi‐stress scenarios.

The resilience of plants to concurrent abiotic stresses—such as drought, salinity, extreme temperatures, heavy metals, and elevated CO2 levels—is paramount in the era climate change. Reactive oxygen species (ROS), traditionally perceived mere byproducts metabolic processes, serve a dual role: crucial signaling molecules that facilitate plant adaptation deleterious agents causing cellular damage when excessively accumulated. In this review, we highlighted intricate equilibrium maintain through both enzymatic non-enzymatic antioxidant defenses mitigate ROS-mediated oxidative stress, emphasizing sophisticated strategies deploy counteract spectrum combined stresses. Some species, however, exhibit insufficient enhancement their intrinsic counterbalance stress-induced ROS accumulation consequent damage. Consequently, explored pivotal role diverse further strengthening defenses, offering profound insights into bolstering resilience. Furthermore, advent genetic engineering technologies unveils novel avenues for crop improvement, with strategic overexpression genes such SOD, APX, CAT, GPX, DHAR, GR, GST showing immense potential fortifying against challenges imposed by multiple Future perspectives entail deepening our understanding molecular mechanisms governing generation scavenging, investigating synergistic effects co-expressing genes, elucidating interactions between endogenous hormones exogenously applied molecules. We advocate integrative research methodologies, combining field experiments, controlled environmental studies, computational modeling, bridge gap laboratory discoveries practical agricultural applications.

Plant communities experience impacts of increasing numbers global change factors (e.g., warming, eutrophication, pollution). Consequently, unpredictable effects could arise. However, information about multi-factor on plant is scarce. To test plant-community responses to multiple (GCFs), we subjected sown and transplanted-seedling (0, 1, 2, 4, 6) co-acting GCFs, assessed individual GCFs community composition productivity. GCF number reduced species diversity evenness both types, whereas none the alone affected these measures. In contrast, positively productivity community. Our findings show that simultaneously acting can affect in ways differing from those expected single factor effects, which may be due biological sampling or both. exploring multifactorial nature crucial better understand ecological change.
