Several lichen species have been used for medicinal purposes throughout the ages, and they were reported to be effective in the treatment of different disorders including tuberculosis, hemorrhoids, ulcer, dysentery and cancer. It is revealed that they may be easily accessible sources of natural drugs that could be used as a possible food supplement or in pharmaceutical industry after their safe...

Selective degradation of peroxisomes (macropexophagy) in Hansenula polymorpha involves the sequestration of individual organelles to be degraded by membranes prior to the fusion of this compartment with the vacuole and subsequent degradation of the whole organelle by vacuolar hydrolases. Here we show that Pex3p, a peroxisomal membrane protein essential for peroxisome biogenesis, escapes this au...

Marine gregarines are poorly understood apicomplexan parasites with large trophozoites that inhabit the body cavities of marine invertebrates. Two novel species of gregarines were discovered in polychaete hosts collected in Canada and Japan. The trophozoites of Trichotokara japonica n. sp. were oval to rhomboidal shaped, and covered with longitudinal epicytic folds with a density of six to eigh...

Receptor-like kinases (RLKs) are regulators of plant development through allowing cells to sense their extracellular environment. They facilitate detection of local endogenous signals, in addition to external biotic and abiotic stimuli. The Catharanthus roseus RLK1-like (CrRLK1L) protein kinase subfamily, which contains FERONIA, plays a central role in regulating fertilization and in cell expan...

– Extensive field collections of small alpheid shrimps in Sungei Buloh and Lim Chu Kang mangroves in Singapore, along with the examination of preserved material, yielded two new species and several new records for South-East Asia and Australia. The description of Salmoneus singaporensis, new species, is based on a single specimen from Singapore, which differs only slightly from the rarely colle...

Organic pollutants effects on lichens have not been addressed. Rehydration is critical for lichens, a burst of free radicals involving NO occurs. Repeated dehydrations with organic pollutants could increase oxidative damage. Our aim is to learn the effects of cumene hydroperoxide (CP) during lichen rehydration using Ramalina farinacea (L.) Ach., its photobiont Trebouxia spp. and Asterochloris e...

The liverwort Marchantia polymorpha is an emerging model organism on account of its ideal characteristics for molecular genetics in addition to occupying a crucial position in the evolution of land plants. Here we describe a method for gene targeting by applying a positive/negative selection system for reduction of non-homologous random integration to an efficient Agrobacterium-mediated transfo...

The liverwort Marchantia polymorpha L. is one of the key model plants in evo-devo studies, and an increasing number of transgenic and mutant lines have been established. For reliable long-term preservation of M. polymorpha plants, spores have been used, but crossing is indispensable to obtain them. Gemmae, however, are vegetative clones and readily available in large numbers without crossing, t...

On the basis of extensive field investigation and a series of herbarium specimen identifications, we present and discuss the descriptions and distribution of 22 species of Ramalina found in the Hengduan Mountains of southwestern China. In this revisionary study, representatives of the Ramalina genus, including R. americana, R. confirmata, R. dendriscoides, R. obtusata, R. pacifica, R. pentecost...

This study was aimed at evaluating the growth promoting effect of symbiotic algal polyol (ribitol) and plant hormones on the lichen-forming fungi (LFF), Ramalina farinacea (CH050010 and 40403) and Ramalina fastigiata. The addition of ribitol to basal (malt-yeast extract) medium enhanced the relative growth rates of all three LFF. R. farinacea (CH050010), R. farinacea (40403) and R. fastigiata (...
