Eleusine indica and Portulaca oleracea are two common weeds in peanut crops in southern Córdoba. Two chemicals are frequently used to control them, quizalofop for grasses and lactofen for dicots. The objective is to study the effects of quizalofop and lactofen on cuticle ultrastructure in E. indica and P. oleracea, respectively. In the lab, quizalofop was applied on E. indica and lactofen on P....

INTRODUCTION Purslane (Portulaca oleracea L., Portulacaceae) is eaten extensively as a potherb, and added in soups and salads around the Mediterranean and tropical Asian countries (Fig. 1). There is a newer interest in cultivation of purslane as a crop since its identification as one of the best sources in the plant world for omega-3 fatty acid, α-linolenic acid (LNA). LNA is a precursor of a s...

Cysteine-rich peptides (CRPs) play important host-defense roles in plants. However, information concerning CRPs in the Cactaceae (cactus) family is limited, with only a single cactus-derived CRP described to date. Here, we report the identification of 15 novel CRPs with three different precursor architectures, bleogens pB1-15 from Pereskia bleo of the Cactaceae family. By combining proteomic an...

The essential oil composition of Peumus boldus and Drimys winterii was analyzed by means of capillary GC-FID and GC-MS. More than 96% of the total oil components (43 and 54 compounds, respectively) were identified, with ascaridole (51.17 ± 9.51), p-cymene (16.31 ± 2.52) and 1,8-cineole (14.45 ± 2.99) as the main compounds in P. boldus and g-eudesmol (21.65 ± 0.41), followed of elemol (12.03 ± 0...

an efficient transformation system for the medicinal plant portulaca oleracea was established using agropine-type agrobacterium rhizogenes atcc15834. hairy roots were obtained directly from cotyledon leaves explants seven days after inoculation with the bacteria. the highest transformation efficiency was obtained from cotyledon leaves explants, and amounted to 53.3% within two weeks. roots grew...
