The enhancement of plant secondary metabolite production in cell suspension cultures through biotic or abiotic elicitation has become a potential biotechnological approach for commercialization or large-scale production of bioactive compounds. Gymnema sylvestre R.Br. is an important medicinal plant, rich in a group of oleanane triterpenoid saponins called gymnemic acid, well known for its anti-...

Only six species of Microvelia have been recorded from Colombia up to the present, namely M. ancona, M. hinei, M. leucothea, M. longipes, M. panamensis, and M. pulchella. Microvelia inguapi sp. n. and M. piedrancha sp. n. are herein described and compared with similar species. An identification key to the Colombian species of Microvelia is presented. 

The expression of many different genes is regulated by ABA and osmotic stress (Skriver and Mundy, 1990). These genes and their products have been characterized in severa1 plants, and they include dehydrins in barley, corn (Close et al., 1989), and Arabidopsis thaliana (Rouse et al., 1992); proteins responsive to ABA (RAB) in rice (Mundy and Chua, 1988; Yamaguchi-Shinozaki et al., 1989); TAS and...

Geholaspis (Geholaspis) pennulatus sp. nov. is described from females and males collected from forest leaf litter in Northern Iran. The new species can be easily recognised by its barbed setae j2 and z1, dorsal shield seta j5 located posterior to j6 and z6, a very wide ventri-anal shield, and the shape of the epistome. Geholaspis (G.) comelicensis Lombardini, 1962 is considered as a junior syno...
