Global climate change (GCC) is posing a serious threat to organisms, particularly plants, which are sessile. Drought, salinity, and the accumulation of heavy metals alter soil composition have detrimental effects on crops wild plants. The hormone auxin plays pivotal role in response stress conditions through fine regulation plant growth. Hence, rapid, tight, coordinated its concentration achieved by modulation at multiple levels. Beyond structural enzymes involved biosynthesis, transport,...
The hyperaccumulation behaviour of PTEs is observed in many edible plants. However, the role soil geochemistry and human health risks associated with uptake by hyperaccumulator plants remain poorly understood. This study analyses 10 topsoil Brassica rapa samples collected from volcanic clay soils, comparing contents As, Cd, Hg Pb assessing their relative risks. To account for geochemical variations were two Italian regions (Sicily Campania) characterized different geological settings....
Abstract The black pepper, most commonly used in Indian cuisines for ages, is considered as “king of spices.” present study evaluates the anticancer potential pepper and its main constituent, i.e. alkaloid piperine, against human leukemia cell line, K-562 cells. Gas chromatography–mass spectrometry (GC–MS) analysis confirmed presence piperine extract. methanolic extract (BP-M) pure (PIP) showed a strong cytotoxic effect this line. Both BP-M PIP generated apoptotic bodies cells caused nuclear...
Apple scab disease caused by the fungus Venturia inaequalis is a devastating that seriously affects quality and yield of apples. In order to understand mechanisms involved in resistance, we performed gas chromatography-mass spectrometry based metabolomics analysis cell culture resistant cultivar 'Florina' susceptible 'Vista Bella' both prior -to -following treatment with V. elicitor (VIE). A total 21 metabolites were identified be altered significantly cultures upon VIE-treatment. Among...
Apple (Malus sp.) and other genera belonging to the sub-tribe Malinae of Rosaceae family produce unique benzoic acid-derived biphenyl phytoalexins. Cell cultures Malus domestica cv. 'Golden Delicious' accumulate two phytoalexins, aucuparin noraucuparin, in response addition a Venturia inaequalis elicitor (VIE). In this study, we isolated expressed cinnamate-CoA ligase (CNL)-encoding sequence from VIE-treated cell (M. CNL; MdCNL). MdCNL catalyses conversion cinnamic acid into cinnamoyl-CoA,...
Abstract Adverse impacts of climate change, including high temperature on cereal crop production, have been evidenced globally. In plants, heat shock factors (HSFs) are crucial components stress associated rescue mechanisms and also required for normal biological processes. Here, we functionally characterized a highly responsive HvHSFA6a in barley by developing constitutively overexpressing transgenic lines. These lines showed tolerant phenotype via improved photosynthesis, antioxidants...
Pistacia palaestina Boiss. is a common tree in the Mediterranean maquis. The leaves of this plant accumulate defensive monoterpenes, whose levels greatly increase galls induced by aphid Baizongia pistaciae. We previously found significant chemopolymorphism monoterpene content among individual trees, but chirality these monoterpenes was unknown. Although most species specifically one enantiomeric form given compound, P. individuals display key accumulated. report here marked variation for...
A simple, precise, rapid and accurate isocratic reversed-phase high-performance liquid chromatographic method was developed validated for the simultaneous determination of biphenyl (aucuparin noraucuparin) dibenzofuran (eriobofuran) phytoalexin from elicitor treated cell culture Sorbus aucuparia (mountain ash). These phytoalexins play crucial role in combating scab disease many commercially important rosaceous plants, such as apple, pear mountain ash. The separation performed a Luna C18...
Colon cancer is the most prevalent cause of death from across globe. Although chemotherapy drugs are predominantly used, their toxicity always remains a concern. As an alternative to synthetic drugs, natural compounds or nutraceuticals comparatively less toxic. Honey widely used different cultures as form medicine. It represents prominent source plant-phenolic and there demonstrable evidence its anti-oxidant anti-microbial activities. The aim present work was investigate anti-proliferative...
Cell cultures of Asian pear ( Pyrus pyrifolia ) are known to produce benzoate‐derived biphenyl phytoalexins upon elicitor treatment. Although the downstream pathway for phytoalexin biosynthesis is almost known, upstream route benzoic acid in has not been completely elucidated. In present work, we report benzaldehyde synthase (BS) activity from yeast extract‐treated cell suspension P. . BS catalyzes vitro conversion trans ‐cinnamic using a non‐oxidative C 2 ‐side chain cleavage mechanism. The...
