Growth chamber experiments were conducted to examine environmental parameters affecting disease development by the indigenous pathogen Bipolaris sacchari isolate LJB-1L on the invasive weed Lygodium microphyllum (Old World climbing fern). An initial experiment examined three different temperature regimes (20/15, 25/20, 30/25 C; light/dark cycle) and three different periods of leaf wetness (12, ...

Desmodium adscendens plant is widely used as juice or tea in various parts of the world against a wide range of diseases. This study determines the quality and the quantity of polyphenols, flavonoids, anthocyanins, and tannins in D. adscendens leaves by UV-spectrophotometry and RP-HPLC methods. In addition, the antioxidant capacity of these phenolic compounds is evaluated by ABTS (2,2'-azino-bi...

Random amplified polymorphic DNA (RAPD) markers were used to study the spatial genetic structure in two populations (Bolarque and Entrepeñas) of endangered cliff specialist Antirrhinum microphyllum Rothm. (Scrophulariaceae). Mantel tests found no significant linear correlations between geographic and genetic data. However, redundancy analysis (RDA) models developed using the spatial data as the...

A distinctive new species, Sesuvium curassavicum Sukhor. (Aizoaceae: Sesuvioideae), restricted to the Caribbean Basin (Kingdom of Netherlands: Curaçao and Bonaire Islands, North Colombia: La Guajira Department, Venezuela: Falcón State), is described illustrated. It differs from all other perennial species growing in West Indies by its papillate stems wrinkled seeds. Based on molecular phylogene...

Bryophytes act as bioindicators and bioaccumulators of metal deposition in the environment. To understand the atmospheric deposition of heavy metals (cadmium (Cd), chromium (Cr), copper (Cu), mercury (Hg), nickel (Ni), lead (Pb), and zinc (Zn)) in Taizhou, East China, samples of moss (Haplocladium microphyllum) were collected from 60 sites selected by a systematic sampling method during the sum...

Tanacetum artemisioides, a pale green annual shrub with several branches from the woody rootstock, grows in different parts of Pakistan [1]. The genus Tanacetum has several important medicinal applications. Some of its species such as T. parthenium have been used traditionally in the treatment of migraine and arthritis; T. vulgare has beneficial effects in gastroduodenal diseases while T. micro...
