Effects of UV B and UV C radiation on viability, growth, and major natural compounds of Malve neglecta L. cells . Faezeh Ghanati*, Faezeh Khatami, and Ebrahim Bemani
Callus cultures were established in vitro from leaf explants of Malva neglecta and were sub-cultured several times until a rapid-growing cell line was obtained. The calluses were exposed to different doses of ultraviolet (UV) radiation as follows: 0, 432, 864, and 1296 J/m2 for UV B and 0, 612, 1284, and 1836 J/m2 for UV C, corresponding to 0, 30, 60, and 90 min radiations, in tandem. Exposure ...
متن کاملEffect of UV-B radiation on photosynthetic pigments and UV-absorbing compounds of three different soybean cultivars (Glycine max L.).
The effects of UV-B radiation on the amount of chlorophyll a, b, carotenoids, flavonoids, anthocyanins, and polyphenols of three soybean cultivars was studied. After germination in the incubator, plants were put in pots of soil and during 3 weeks and irrigated with Hoagland solution every day. After 3 weeks, plants were exposed to UV-B for 20 min every day for a week. In each cultivar, UV-B red...
متن کاملMolecular responses of plant cells to UV-B radiation
UV-B radiation (UV-B: 280-320 nm) can cause a wide range of responses in plant cells. These responses depend on the perception of the UV-B radiation, signal transduction mechanisms and modification of gene expression. Studies over the last ten years have revealed a complex molecular response of plant cells to UV-B radiation. Specific changes in gene activity take place and a number of signal tr...
متن کاملA UV-B-specific signaling component orchestrates plant UV protection.
UV-B radiation in sunlight has diverse effects on humans, animals, plants, and microorganisms. UV-B can cause damage to molecules and cells, and consequently organisms need to protect against and repair UV damage to survive in sunlight. In plants, low nondamaging levels of UV-B stimulate transcription of genes involved in UV-protective responses. However, remarkably little is known about the un...
متن کامل[Melanoma, altitude, and UV-B radiation].
BACKGROUND AND OBJECTIVES UV radiation is the main modifiable risk factor for the development of cutaneous melanoma. Many people in the Spanish province of Granada live at high altitudes and, therefore, receive high doses of UV-B radiation. The aims of this study were to assess the possible association between melanoma and altitude and to measure the daily erythemal dose at different altitudes....
