Chitosan‐induced modulation of secondary metabolism and stress tolerance in Salvia rosmarinus under combined drought and heat stress

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Abiotic stresses, particularly drought and elevated temperatures, negatively affect plant physiological and metabolic processes. This study investigated the effects of drought, heat, and combined stress on Salvia rosmarinus (rosemary), and evaluated foliar‐applied chitosan as a biostimulant.

Viabilidad de polen e irregularidades meióticas en una colección de stevia rebaudiana (Bertoni) Bertoni cultivada en Tucumán, Argentina [PDF]

, 2018
Stevia rebaudiana (Bertoni) Bertoni (2n=2x=22) (Asteraceae family) is a species of economic value due to the presence of steviol glycosides in leaves -mainly stevioside and rebaudioside A- which are non-caloric sugars.

Deciphering Role of Endophytes in Plant Defences and Biotic Stress Resilience Across Families

Plant, Cell &Environment, EarlyView.
ABSTRACT Plant families generate distinct repertoires of specialised metabolites that govern their biotic interactions. Endophytes strengthen host plant defence mechanisms and tolerance to biotic challenges by upregulating metabolite biosynthesis, modifying precursor compounds into more potent forms, or by directly synthesising analogous defence ...

The First Glycosides Isolated from Propolis: Diterpene Rhamnosides

Zeitschrift für Naturforschung C, 2001
Abstract Two diterpene glycosides, ent8(17)-labden-15-O-α-ʟ-rhamnoside and ent-8(17)-labden-15-O-(3′-O-acetyl)-α-ʟ-rhamnoside (new natural compounds) were isolated from propolis from El Salvador. The compounds showed significant antibacterial activity and moderate toxicity to Artemia salina nauplii.
