Effect of Light Availability on the Interaction between Maritime Pine and the Pine Weevil: Light Drives Insect Feeding Behavior But Also the Defensive Capabilities of the Host.

Frontiers in plant science

Suárez-Vidal E, López-Goldar X, Sampedro L, Zas R.
PMID: 28912787
Front Plant Sci. 2017 Aug 29;8:1452. doi: 10.3389/fpls.2017.01452. eCollection 2017.

Light is a major environmental factor that may determine the interaction between plants and herbivores in several ways, including top-down effects through changes in herbivore behavior and bottom-up effects mediated by alterations of plant physiology. Here we explored the...

AIM: The purpose of this study was to evaluate how increasing NaCl salinity in the medium can affects the essential oils (EOs) composition and phenolic diterpene content and yield in leaves of Salvia officinalis L. The protective role of...

Effects of diterpene esters of tigliane, daphnane, ingenane, and lathyrane types on pink bollworm,Pectinophora gossypiella saunders (Lepidoptera: Gelechiidae).

Journal of chemical ecology

PMID: 24309846
J Chem Ecol. 1985 Feb;11(2):191-206. doi: 10.1007/BF00988202.

Twenty esters, representing the biogenetically related tigliane, daphnane, ingenane, and lathyrane series of diterpenes, were screened for growth-inhibitory and insecticidal effects on newly hatched larvae of the North American cotton pest,Pectinophora gossypiella (pink bollworm). Among the tigliane derivatives tested,...

Heterologous expression of the isopimaric acid pathway in Nicotiana benthamiana and the effect of N-terminal modifications of the involved cytochrome P450 enzyme.

J Biol Eng. 2015 Dec 22;9:24. doi: 10.1186/s13036-015-0022-z. eCollection 2015.

BACKGROUND: Plant terpenoids are known for their diversity, stereochemical complexity, and their commercial interest as pharmaceuticals, food additives, and cosmetics. Developing biotechnology approaches for the production of these compounds in heterologous hosts can increase their market availability, reduce their...

BACKGROUND: Different species of Croton are used in traditional Amazonian medicine. Among the popular uses are treatment of bacterial diseases, poorly healing wounds and fevers.OBJECTIVE: This study evaluated the antileishmanial, antiplasmodial and antimicrobial activities of the extracts and diterpenes...

Chemical ecology of canarian laurel forest: Toxic diterpenes fromPersea indica (Lauraceae).

Journal of chemical ecology

Gonzalez-Coloma A, Hernandez MG, Perales A, Fraga BM.
PMID: 24264325
J Chem Ecol. 1990 Sep;16(9):2723-33. doi: 10.1007/BF00988081.

The tree speciesP. indica (Lauraceae) is an important endemism in the Canary Islands laurel forest and can readily be distinguished by its defoliated appearance due to the seasonal action of wild rats (Rattus rattus), which eat the plant and...

Acetylated DNA-damaging clerodane diterpenes from Casearia sylvestris.

Phytochemistry

de Carvalho PR, Furlan M, Young MC, Kingston DG, Bolzani VS.
PMID: 11711078
Phytochemistry. 1998 Nov 20;49(6):1659-1662. doi: 10.1016/s0031-9422(98)00249-0.

In addition to the known diterpene casearin G (1), two new clerodane diterpene casearins type, casearin S (2) and casearin T (3), were isolated from an acetylated bioactive CH(2)Cl(2)/MeOH extract from leaves of Casearia sylvestris. The diterpenes 1-3 exhibited...

New furanocembranoid diterpenes from the soft coral sinularia maxima .

Journal of natural products

Venkateswarlu Y, Sridevi KV, Rao MR.
PMID: 10346962
