“…In the present study, the concentration of UV-B absorbing compounds at 300 nm, which is characteristic of flavonoids, increased 60%, when compared to the control plants, in response to UV-B radiation ( Figure 1A). These results are in agreement with the findings in the recent meta-analysis by Li et al (2010), which showed that, in herbaceous plants, UV-B-absorbing compounds increased by 37% under high UV-B treatments. Moreover, there is a high correlation between total leaf phenolic concentration and UV-B absorbing capacity in plants (Levizou & Manetas, 2002).…”

“…Li et al (2010) observed that supplemental UV-B radiation had significant negative effects on herbaceous photosynthetic rates of a wide range of species, from woody to herbaceous ones. The negative effects of UV-B on photosynthetic processes have been verified under both field (Correia et al, 2005) and greenhouse conditions (Cechin et al, 2008).…”

“…Because the amount of UV-B used in the present study was detrimental to photosynthesis and shoot biomass accumulation, the curling response may be an expression of UV-B damage. Li et al (2010) showed that herbaceous and woody plants had a decrease in shoot biomass of 16.6 and 8.4%, respectively, due to UV-B exposure. Contradictory results reported in the literature can be explained by the fact that plant responses to UV-B radiation depend on a number of parameters, including the developmental stage of tissue, the plant species, and growth conditions.…”

-The objective of this work was to evaluate the effects of UV-B radiation on the vegetative growth and on the gas exchange characteristics of passion fruit plants (Passiflora edulis) grown in greenhouse. The average unweighted UV-B radiation near the apex of the plants was 8 W m -2 for the UV-B treatment (high UV-B), and 0.8 W m -2 for the control plants (low UV-B). Plants were irradiated with UV-B for 7 hours per day, centered on solar noon, during 16 days. High UV-B radiation resulted in lower shoot dry matter accumulation per plant. The content of UV-B absorbing compounds and anthocyanins was increased in the plants exposed to high UV-B radiation, when compared with the control. UV-B radiation did not affect stomatal conductance or transpiration rate, but reduced photosynthesis and instantaneous water-use efficiency, and increased intercellular CO 2 concentration. The accumulation of UV-B-absorbing compounds and anthocyanins did not effectively shield plants from supplementary UV-B radiation, since the growth and photosynthetic processes were significantly reduced.Index terms: Passiflora edulis, anthocyanins, growth, phenolic compounds, photosynthesis. Sensitividade do maracujazeiro-amarelo à radiação ultravioleta-BResumo -O objetivo deste trabalho foi avaliar o efeito da radiação UV-B no crescimento vegetativo e nas características das trocas gasosas de plantas de maracujazeiro-amarelo (Passiflora edulis), cultivadas em casa de vegetação. A radiação média não ponderada de UV-B próximo ao topo das plantas foi de 8 W m -2 , para plantas tratadas com UV-B (alta UV-B), e de 0,8 W m -2 para plantas controle (baixa UV-B). As plantas foram irradiadas com UV-B por 7 horas por dia, centralizadas ao redor do meio-dia, durante 16 dias. Alta radiação de UV-B reduziu o acúmulo de matéria seca da parte aérea da planta. O conteúdo de compostos que absorvem UV-B e de antocianinas foi aumentado nas plantas expostas à alta radiação UV-B, quando comparado às plantas controle. A radiação UV-B não alterou a condutância estomática ou a taxa de transpiração, mas reduziu a fotossíntese e a eficiência instantânea do uso da água, e aumentou a concentração intercelular de CO 2 . O acúmulo de compostos que absorvem UV-B e antocianinas não protegeram de forma efetiva as plantas contra o aumento da radiação suplementar UV-B, visto que o crescimento e os processos fotossintéticos foram significativamente reduzidos.Termos para indexação: Passiflora edulis, antocianinas, crescimento, compostos fenólicos, fotossíntese.

“…Expression of genes such as COP1, which are regulated by the photoreceptor UVR8, and up-regulation of UV-absorbing secondary metabolites leads to acclimation to ambient UV-B [15] [16]. Herbaceous plants tend to produce more UV-B-absorbing compounds in response to elevated levels of UV-B in comparison to woody plants [17].…”

UV-B radiation has been widely documented as a stressor for plants that can cause decreased biomass, reduction in photosynthesis, and oxidative stress. Trigonelline is a secondary metabolite that is biosynthesized in some plants in response to abiotic stress such as UV-B irradiation. The objectives of this study were to examine biochemical stress responses for peanut plants (Arachis hypogaea L.) of four different genotypes (Spanish, Valencia, Virginia, and Runner) after exposure at various lengths to UV-B radiation and to examine the alteration of trigonelline biosynthesis due to the age of the plants. Peanut plants from the genotypes were exposed to UV-B radiation at three exposure times (60, 120, and 180 min); plants from two growth stages, the flowering (R1) and early maturity (R7), were used. Significant positive correlations (r s 0.29 -0.74, P ≤ 0.05) were found for trigonelline concentrations and UV-B exposure times. With longer exposure times of 180 min for plants at R7, trigonelline biosynthesis began as early as 10 days after treatment with 154.6 μg·g −1 DW and remained or increased by up to 71.5 μg•g −1 DW (46.3%) throughout the sampling intervals (10,20,30,40, and 50 days after treatment) to a final value of 226.1 μg•g −1 DW. All four genotypes at R7 exhibited trigonelline concentrations 47.3% to 52.4% (71.6 to 96.5 μg·g −1 DW) higher than individuals at R1. Trigonelline biosynthesis at R7 was significantly (P < 0.05) affected by all levels of UV-B exposure, whereas trigonelline concentrations at R1 were significantly influenced (P < 0.05) by only the longer exposure times (120 and 180 min). No statistically significant difference was found in trigonelline concentration among the four different genotypes. UV-B irradiation had the greatest effect on plants at R7 after 120 and 180 min of exposure, as 15 out of 20 (75%) individuals had significantly higher (P < 0.05) trigonelline
