“…The vast majority of UV-C (200-280 nm) and UV-A (320-400 nm) radiations are absorbed by atmospheric gases. UV-B radiation (280-320 nm) is absorbed by stratospheric ozone but a small proportion is transmitted to the earth's surface (Frohnmeyer & Staiger 2003). Plants receiving UV-B on the earth surface may produce reactive oxygen species (ROS) as superoxide (O2 -) and hydrogen peroxide (H2O2) by more than one mechanism.…”

“…Additionally, the Fenton-type reaction between H2O2 and redox active metal like Fe and Cu produces the aggressive hydroxyl radical (OH • ). ROS cause damage to proteins, lipids and DNA, affecting cell integrity, morphology and physiology of plants (Frohnmeyer & Staiger 2003). The molecular plant response to UV-B involves mechanisms of DNA repair (Pang & Hays 1991), up-regulation of non-enzymatic antioxidants as glutathione and ascorbate, increasing activities of superoxide dismutase (SOD), catalase (CAT) and ascorbate peroxidase (APX) (Jansen, Gaba & Greenberg 1998), and accumulation of compounds that absorb UV-B (Hahlbrock & Scheel 1989;Tevini & Teramura 1989;Li et al 1993).…”

The link between ultraviolet (UV)-B, nitric oxide (NO) and phenylpropanoid biosynthetic pathway (PPBP) was studied in maize and Arabidopsis. The transcription factor (TF) ZmP regulates PPBP in maize. A genetic approach using P-rr (ZmP+) and P-ww (ZmP-) maize lines demonstrate that: (1) NO protects P-rr leaves but not P-ww from UV-B-induced reactive oxygen species (ROS) and cell damage; (2) NO increases flavonoid and anthocyanin content and prevents chlorophyll loss in P-rr but not in P-ww and (3)

“…Shortwave UV-C is completely absorbed by atmospheric gases, while UV-B is partially absorbed by the stratospheric ozone (O 3 ), leaving only a small fraction (<0.5% of total sunlight energy) transmitted to the Earth surface. UV-A, on the other hand, is not absorbed by ozone [130,132]. Over the last 50 years, the ozone concentration has diminished by 5%, mainly due to the release of anthropogenic pollutants, such as chlorofluorocarbons (CFCs) and other halogenated ozonedepleting substances [126,133].…”

Grapevine is one of the most abundant crops worldwide, with varieties destined for fresh and dry consumption, as well as wine production. Unfortunately, grapevine plants are affected by both biotic and abiotic stresses, generating significant economic losses. These conditions can negatively impact grape cultivation at different stages: plant and berry development during pre-and post-harvest, production, fresh fruit processing and export, along with wine quality. Most of the grapevine varieties are susceptible to several pathogens and within this chapter, particular attention is given to fungi (Botrytis cinerea and Erysiphe necator) and viruses, since they are a worldwide concern. Within the latter, special focus is given to the grapevine leafroll disease, a complex and destructive infection. On the other hand, abiotic stress is also relevant in grapevine, and in this chapter it will be exemplified by UV-B radiation and its impact on growth and fruit development, plant adaptive responses and its relationship with the quality of grape berries for winemaking. The main biotic and abiotic grapevine stress factors are reviewed in this chapter, considering a special focus on biotechnological approaches carried out in order to address them and minimize their detrimental consequences.

“…Besides, UV-B plays an important role in the evolution of protective floral forms in alpine plants (Zhang et al 2014). In general, plants respond differently to irradiation with low or high doses of UV-B (Frohnmeyer & Staiger 2003). It has shown that low doses of UV-B enhance a phytochrome-Bmediated photomorphogenic response in Arabidopsis (Boccalandro et al 2001).…”

“…However, higher dosages are very detrimental to plants, the enhanced UV-B radiation caused a negative effect on plant growth and yield (Masih & Kulkarnee 2010), elevated UV-B radiation has pleiotropic effects on plant development, morphology and physiology (Frohnmeyer & Staiger 2003). The height, catalase (CAT) activity, initial fluorescence (Fo), variable fluorescence (Fv) and photochemical efficiency of PSII (Fv/Fm) of wheat decreased significantly while malondialdehyde content on the contrary under the enhanced UV-B (Tie et al 2014).…”

Actin filaments play a significant role in regulating the cell cycle. The dynamic rearrangement of actin filaments are regulated by actin-binding proteins profilin (PFN). However, the distribution of PFN in root-tip cells and the role of PFN in the UV response have been unknown. Here, we observed the distribution of PFN during every stage of wheat cell mitosis in the control and UV-B treatment group, and found that PFN showed a punctuate pattern of localization around the periphery of nuclear envelopes in interphase and gathered toward the cell bipolar in prophase in the control treatment group. During metaphase, PFN presented a cage shape that is formed around the chromosomes, then appeared in the equator during anaphase, and re-distributed around the periphery of nuclear envelopes during cytokinesis. But PFN localization had changed under enhanced UV-B radiation (10.08 kJm -2 h -1 ), PFN displayed an annular distribution in interphase and, during metaphase, relatively large number of PFN distributed in one of the four corners or gathered in the four corners in the cell. However, two corners of PFN moved to the other two corners along the direction perpendicular to the cell-elongating axis during telophase. And these aberrant distributions of PFN were often associated with abnormal chromosome distribution. ARTICLE HISTORY
