1. Methyl jasmonate modulation reduces photosynthesis and induces synthesis of phenolic compounds in sweet potatoes subjected to drought
ABSTRACT Sweet potato [Ipomoea batatas (L.) Lam.] has wide adaptability to different climatic conditions. However, its yield can be affected by prolonged periods of drought. Application of exogenous jasmonates can modulate several physiological and biochemical processes, improving plant tolerance to abiotic stress. This study sought to evaluate the role of e

4. Increased polyphenols and antioxidant activity of rice bean (Vigna umbellata L.) sprouts induced by Methyl Jasmonate: the promotion effect of Methyl Jasmonate on rice bean sprouts
Abstract Rice bean (Vigna umbellata L.) sprouts are richer in metabolites and biological activities after germination. The total polyphenol and total flavonoid contents were analyzed during the sprouting process. The antioxidant activities of the sprouts were tested using 1,1-diphenyl-2- picrylhydrazyl radical (DPPH) screening assay. To determine the reason

5. Increased antioxidant activity and polyphenol metabolites in methyl jasmonate treated mung bean (Vigna radiata) sprouts
Abstract Mung bean sprouts are a popular health food both in China and worldwide. We determined the optimal concentration of exogenous methyl jasmonate (MeJA) for the promotion of the sprouting in mung beans (Vigna radiata). The 1,1-diphenyl-2- picrylhydrazyl radical (DPPH) scavenging test showed that MeJA application resulted in significantly improved antio

6. Effect of exogenous phytohormones treatment on glycyrrhizic acid accumulation and preliminary exploration of the chemical control network based on glycyrrhizic acid in root of Glycyrrhiza uralensis
ABSTRACT One-year-old Glycyrrhiza uralensis Fisch. ex DC, Fabaceae, was treated with three exogenous phytohormones in June and July, namely gibberellin, auxin (indole-3-acetic acid), methyl jasmonate at different concentrations. Control plants were treated with water. Roots of controls and hormones-treated G. uralensis plants were harvested at different time

7. Azadirachtin biosynthesis induction in Azadirachta indica A. Juss cotyledonary calli with elicitor agents
The use of cell and plant tissues culture techniques to produce economically important active metabolites has been growing. Among these substances, azadirachtin (AZA), produced by the neem tree (Azadirachta indica), has received considerable attention due to its bioinsecticide action. The main goal of this work was to analyze the AZA levels in neem cotyledon

8. Volatile organic compounds for the control of Meloidogyne exigua in Coffea arabica
Meloidogyne exigua is a plant-parasitic nematode that causes great losses to coffee farmers. Thus, to contribute to the development of new products to control this parasite, the present work studied the effect of volatile organic compounds (VOC) on the nematode and coffee plants (Coffea arabica), since these compounds are known to be used in plant defense ag

9. Produção de carotenoides em culturas in vitro de Cleome rosea Vahl ex DC (Capparaceae) e avaliação de sua toxicidade e potencial antioxidante / Carotenoid production in vitro cultures of Cleome rosea Vahl ex DC (Capparaceae) and evaluation of toxicity and antioxidant potential.
The production and optimization of plants secondary metabolites with medicinal value have been achieved by using plant tissue culture techniques, which have showed great relevance when considering the conservation status of a species or their occurrence in degraded environments. The present study assessed the production of carotenoids in callus and cell susp

10. Caracterização da expressão de inibidores de poligalacturonases (PGIPs) em resposta aos estresses biótico e abiótico em plantas de feijão comum (Phaseolus vulgaris L.) / Characterization of the expression of polygalacturonase inhibitors (PGIPs) in response to biotic and abiotic stresses in plants of common bean (Phaseolus vulgaris L.)
Sclerotinia sclerotiorum (Lib.) de Bary is a necrotrophic fungal pathogen that causes the disease known as white mold in many plants. During infection, it secretes several endopolygalacturonases (PGs) to degrade cell wall pectin. To counteract the action of PGs, plants express polygalacturonases-inhibiting proteins (PGIPs) that reduce the hydrolytic activity

Caracterização da expressão de inibidores de poligalacturonases (PGIPs) em resposta aos estresses biótico e abiótico em plantas de feijão comum (Phaseolus vulgaris L.) / Characterization of the expression of polygalacturonase inhibitors (PGIPs) in response to biotic and abiotic stresses in plants of common bean (Phaseolus vulgaris L.)
Sclerotinia sclerotiorum (Lib.) de Bary é um fungo necrotrófico patogênico causador da doença conhecida como mofo branco em muitas plantas. Durante a infecção, secreta várias endopoligalacturonases (endo-PGs) que degradam a pectina da parede celular da planta hospedeira. Para contrapor à ação das PGs, as plantas produzem proteínas inibidoras de po

12. Seed priming with hormones does not alleviate induced oxidative stress in maize seedlings subjected to salt stress
Seed priming with hormones has been an efficient method for increasing seed vigor as well as seedling growth under stressful conditions. These responses have in the past been attributed to the activation of antioxidant systems in a range of crops. The results described in this work show that hormonal priming with methyl jasmonate, salicylic acid or CEPA (chl
