Trichomes play a crucial role in plant resistance to abiotic and biotic stresses, and their development and characteristics vary across different species. This study demonstrates that trichomes of Lilium pumilum exhibit synchronized growth during flower bud differentiation and enhance the plant's adaptability to UV-B radiation and aphid infection. We identified LpNAC48, a NAC family transcription factor (TF), that interacted with the B-box (BBX) family TF LpBBX28, during trichome formation in L.

New tetrakis Eu and Gd β-diketonate complexes containing benzimidazolium (Bzim) as the counterion were synthesized by the one-pot method. The Bzim[Eu(tta)]·HO complex was further incorporated into a poly(methyl methacrylate) matrix (PMMA) at 1, 5, and 10% (w/w), which revealed highly desirable photonic features. The Eu and Gd complexes were characterized by elemental and thermal analyses, in addition to ESI-MS spectrometry, FTIR, and Raman spectroscopy.

Background: It is well-known that ultraviolet B (UVB) causes cataracts by inducing pyroptosis and the production of reactive oxygen species (ROS) in human lens epithelial cells (HLECs). The transcription factor E2F1 (E2F1) serves as a positive regulator of disrupted pathways involved in histone modification and cell cycle regulation. However, its function in UVB-treated HLECs remains unknown.

Despite extensive research, determining the optimal level of sunlight exposure for human health remains a challenge, emphasizing the need for ongoing scientific inquiry into this critical aspect of human well-being. This review aims to elucidate how different components of the solar spectrum, particularly near-infrared (NIR) radiation and ultraviolet radiation (UVR) affect human health in diverse ways depending on factors such as time of day and duration of exposure. Sunlight has beneficial effects from the production of melatonin by NIR and vitamin D by UVB.

The raising economic importance of cannabis arouses interest in positively influencing the secondary plant constituents through external stimuli. One potential possibility to enhance the secondary metabolite profile is the use of UV light. In this study, the influence of spectral UV quality at different intensity levels on photomorphogenesis, growth, inflorescence yield, and secondary metabolite composition was investigated.
