Marchantia polymorpha is an extant relative of the earliest terrestrial plants and has attracted a substantial interest as a model organism for evolutionary and developmental studies. Given its relatively simple genome, compact gene families, simple morphology, ease of propagation and transformation, M. polymorpha is becoming a promising platform for plant synthetic biology. Modular genetic par...

BACKGROUND beta-Lactams like penicillin and cephalosporin are among the oldest known antibiotics used against bacterial infections. Industrially, penicillin is produced by the filamentous fungus Penicillium chrysogenum. Our goal is to introduce the entire penicillin biosynthesis pathway into the methylotrophic yeast Hansenula polymorpha. Yeast species have the advantage of being versatile, easy...

The two-spotted leafhopper, Sophonia rufofascia (Kuoh and Kuoh), is an exotic pest from South-East Asia that attacks a wide variety of plant species in Hawaii. Myrica faya Aiton is an aggressive exotic weed that displaces and excludes native plants in Hawaiian forests. It has been argued that because of the high nutritional quality of its foliage, M. faya might facilitate leafhopper invasion of...

Saccharomyces cerevisiae SU50B and Hansenula polymorpha 8/2, both carrying a multicopy integrated guar alpha-galactosidase, have been cultivated in continuous cultures, using various mixtures of carbon sources and cultivation conditions. Both S. cerevisiae SU50B and H. polymorpha 8/2 are stable and produce high levels of extracellular alpha-galactosidase in continuous cultures for more than 500...

Climate change in the Mediterranean-like regions of South Africa has resulted increased rainfall variability, a delayed start to wet winter season, and occurrences out-of-season summer events. These changes bioclimatic conditions are predicted become more pronounced and, therefore, could result poor seedling establishment false breaks from soil seed bank, followed by desiccation annual medic cl...

to evaluate of drought stress and foliar application of zinc and iron on two annual medics species, experimental field was carried out with split factorial based on randomized complete block design in three replication with treatments of foliar application (controlled, fe, zn and iron+ zinc) and cutoff irrigation from (50% flowering , lower pod maturity,10 days before starting of flowering and ...

The liverwort Marchantia polymorpha is a member of the most basal lineage of land plants (embryophytes) and likely retains many ancestral morphological, physiological and molecular characteristics. Despite its phylogenetic importance and the availability of previous EST studies, M. polymorpha's lack of economic importance limits accessible genomic resources for this species. We employed Illumin...
