“…Although it was observed that the change in the number of stomata changes depending on the application, the reactions of increasing and decreasing the number of stomata were different in different species exposed to the same applications. [27] stated that the density of axial stomata in Wedelia chinensis (Osbeck) Merr. plant, which was exposed to UV-B radiation, increased.…”

In recent years, changing climatic conditions have brought along many problems. As a result of the increasing destruction of the ozone layer caused by anthropogenic sources, the effect of harmful sun rays reaching our world is increasing. It is estimated that the temperatures on the earth's surface and ultraviolet-B (UV-B) radiation will increase in the coming years due to global climate change. This study used ash-leaved maple (Acer negundo) and sycamore maple (Acer pseudoplatanus) seedlings to examine the effects of drought and UV-B radiation levels that may occur in the coming years on forest trees. The study investigated the effect on stomatal characters by applying two different doses of UV-B and drought stress. As a result of the study, it was determined that UV-B stress had a more significant effect on stomatal characters than drought stress. It has been observed that severe drought generally reduces the number of stomata. It was determined that the sycamore maple was more affected by severe drought and UV-B radiation. While UV-B radiation decreased only the stomatal pore length and width in sycamore maple, it increased the stomatal pore length and width in ash-leaved maple. The response of stomatal characters to drought and UV-B stress remains unclear. Therefore, more detailed studies are required.

The increased ultraviolet radiation (UV) due to the altered stratospheric ozone leads to multiple plant physiological and biochemical adaptations, likely affecting their interaction with other organisms, such as pests and pathogens. Arbuscular mycorrhizal fungi (AMF) and UV-B treatment can be used as eco-friendly techniques to protect crops from pests by activating plant mechanisms of resistance. In this study, we investigated plant (Lactuca sativa) response to UV-B exposure and Funneliformis mosseae (IMA1) inoculation as well as the role of a major insect pest, Spodoptera littoralis. Lettuce plants exposed to UV-B were heavier and taller than non-irradiated ones. A considerable enrichment in phenolic, flavonoid, anthocyanin, and carotenoid contents and antioxidant capacity, along with redder and more homogenous leaf color, were also observed in UV-B-treated but not in AMF-inoculated plants. Biometric and biochemical data did not differ between AMF and non-AMF plants. AMF-inoculated plants showed hyphae, arbuscules, vesicles, and spores in their roots. AMF colonization levels were not affected by UV-B irradiation. No changes in S. littoralis-feeding behavior towards treated and untreated plants were observed, suggesting the ability of this generalist herbivore to overcome the plant chemical defenses boosted by UV-B exposure. The results of this multi-factorial study shed light on how polyphagous insect pests can cope with multiple plant physiological and biochemical adaptations following biotic and abiotic preconditioning.
