Weed management is essential for sustainable crop production in all cropping systems. The use of herbicides causing the problems herbicide resistant weeds and environmental pollution. Plant-released phytotoxins have ability to promote or inhibit germination seedling growth surrounding crops weeds. Therefore, it imperative identify plant species having herbicidal potential as more safe weed appr...

Since the availability of first complete DNA sequence of chloroplast genome of Marchantia polymorpha several studies to determine the structure and organization of chloroplast genomes of various plant groups have been made. However the lineage sampling of bryophytes are poorly represented in complete chloroplast genome sequences (only three liverworts, two mosses and one hornwort). This review ...

Cytoplasmic microtubules (cMT) control mitotic spindle positioning in many organisms, and are therefore pivotal for successful cell division. Despite its importance, the temporal control of cMT formation remains poorly understood. Here we show that unlike the best-studied yeast Saccharomyces cerevisiae, position of pre-anaphase nucleus is not strongly biased toward bud neck in Ogataea polymorph...

To discover mechanisms that controlled the growth of the rooting system in the earliest land plants, we identified genes that control the development of rhizoids in the liverwort Marchantia polymorpha. 336,000 T-DNA transformed lines were screened for mutants with defects in rhizoid growth, and a de novo genome assembly was generated to identify the mutant genes. We report the identification of...

We have isolated the Penicillium chrysogenum pex5 gene encoding the receptor for microbody matrix proteins containing a type 1 peroxisomal targeting signal (PTS1). Pc-pex5 contains 2 introns and encodes a protein of approximately 75 kDa. P. chrysogenum pex5 disruptants appear to be highly unstable, show poor growth, and are unable to sporulate asexually. Furthermore, pex5 cells mislocalize a fl...

We have studied the in vitro inactivation/dissociation and subsequent reactivation/re-assembly of peroxisomal alcohol oxidases (AO) from the yeasts Hansenula polymorpha and Pichia pastoris. Both proteins are homo-oligomers consisting of eight identical subunits, each containing one FAD as the prosthetic group. They were both rapidly inactivated upon incubation in 80% glycerol, due to their diss...

An evaluation was made of media and tests used for differentiating nonfermenting gram-negative bacteria encountered in medical bacteriology in order to determine those diagnostic procedures most useful in identifying these bacteria. The organisms examined included Alcaligenes faecalis, A. odorans var. viridans, Moraxella duplex (Mima polymorpha var. oxidans), Acinetobacter anitratum (Herellea v...

Hansenula polymorpha Pex14p (HpPex14p) is a component of the peroxisomal membrane essential for peroxisome biogenesis. Here, we show that HpPex14p is phosphorylated in vivo. In wild-type H. polymorpha cells, grown in the presence of [32P]orthophosphate, the 32P label was incorporated into HpPex14p. Labelled HpPex14p was induced after a shift of cells to methanol-containing media and rapidly dis...
