THE ‘VIRGATA’

First Resistance Mechanisms Characterization in Glyphosate-Resistant Leptochloa virgata

Leptochloa virgata (L.) P. Beauv. is an annual weed common in citrus groves in the states of Puebla and Veracruz, Mexico limiting their production. Since 2010, several L. virgata populations were identified as being resistant to glyphosate, but studies of their resistance mechanisms developed by this species have been conducted. In this work, three glyphosate-resistant populations (R8, R14, and...

Antioxidant Properties and Phenolic Composition of Salvia Virgata Jacq

Effects of Salvia virgata Jacq. on Jurkat Clone-E6

Objectives: The genus Salvia is one of the most widespread members of the Lamiaceae family and S.virgata Jacq. decoction is traditionally used for leukemia in Turkey. In this study, water extract and methanol extract of S. virgata were investigated for their antiproliferative effects on Jurkat (Clone E6-1) leukemia cell lines and also GSH-Px, SOD and MDA levels were evaluated as oxidative stres...

Antinociceptive Activity of the Chloroform Fraction of Dioclea virgata (Rich.) Amshoff (Fabaceae) in Mice

Acute treatment with the chloroform fraction of Dioclea virgata (Rich.) Amshoff (CFDv) in mice produced decreased ambulation and sedation in the behavioral pharmacological screening. Doses of 125 and 250 mg/kg CFDv decreased latency of sleep onset in the test of sleeping time potentiation. In the open field, animals treated with CFDv reduced ambulation and rearing (250 mg/kg), as well as defeca...

Microsporogenesis in Paspalum conspersum Schrad. (Virgata group) with different ploidy levels.

Knowledge about the cytology and reproductive behavior of a species is indispensable for hybridization programs. This is especially true for species belonging to the genus Paspalum, among which apomixis and a wide range of ploidy levels are frequently found. Paspalum conspersum Schrad. is a robust and warm-season perennial bunchgrass native to South America. Previous studies have indicated that...
