Peganum harmala (Zygophyllaceae) is an intriguing herb with a long history of medicinal use. Antifungal activity of P. harmala seed extract against certain fungal species was investigated in vitro. Antifungal activity of the extract of P. harmala seeds was investigated against several fungal species using in vitro agar dilution technique. The fungal species included: Microsporum canis, Microspo...

Maternal control of higher plant seed development is likely to involve female sporophytic as well as female gametophytic genes. While numerous female sporophytic mutants control the production of the ovule and the embryo sac true maternal effect mutations affecting embryo and endosperm development are rare in plants. A new class of female gametophytic mutants has been isolated that controls aut...

Polycomb group (PcG) proteins are evolutionary conserved proteins that stably maintain established transcriptional patterns over cell generations. The FERTILIZATION INDEPENDENT SEED (FIS) PcG complex from plants has a similar composition to the Polycomb repressive complex 2 from animals. Mutations in FIS genes cause parent-of-origin-dependent seed abortion. Every seed inheriting a mutant fis al...

The mussel aquaculture industry has raised concerns following the discovery of green crab Carcinus maenas in Placentia Bay Newfoundland in August 2007. Post-larval green crabs have been found in feral mussel beds in high densities in Europe. If this is true for other green crab populations, mussel seed transfers from Placentia Bay could provide a vector for post-larval juvenile crab transfer to...

Winter rapeseed (Brassica napus L.) has potential to become an alternate oilseed crop both for edible oil production and energy agriculture (biofuel production) for Turkey. This study was conducted to determine the effect of year, N sources and doses on the yield and quality traits of winter rapeseed in a cereal system in calcareous soils over two seasons, 2000-2001 and 2001-2002, in Central An...

Spaced seeds have been shown to be superior to continuous seeds for efficient and sensitive homology search based on the seedand-extend paradigm. Much the same is true in genome mapping of high-throughput short-read data. However, a highly sensitive search with multiple spaced patterns often requires the use of a great amount of index data. We propose a novel seed-set construction method for ef...

Rodents affect the post-dispersal fate of seeds by acting either as on-site seed predators or as secondary dispersers when they scatter-hoard seeds. The tropical forests of north-east India harbour a high diversity of little-studied terrestrial murid and hystricid rodents. We examined the role played by these rodents in determining the seed fates of tropical evergreen tree species in a forest s...

The Australian Native Seed Sector survey was conducted in 2016–2017 under the auspices of Network for Plant Conservation. Respondents self-selected into a seed supply (Seed Collector, Production Area Grower) or demand Purchaser, Other User) group category. Issue statements facing sector with respect to limiting opportunities ecological restoration were presented respondents who ranked them orde...

This paper presents a new pixel labeling algorithm for complex histology image segmentation. For each image pixel, a Gaussian mixture model is applied to estimate its neighborhood intensity distributions. With this local distribution fitting, a set of pixels having a full set of source classes (e.g. nuclei, stroma, connective tissue, and background) in their neighborhoods are identified as the ...

in this study, geometrical, gravimetrical and frictional properties of four common varieties of iranian canola seeds (namely: slm, hyola, okapi, orient), containing the mean moisture value of 6.5% (w.b.) were investigated. geometrical and gravimetrical properties included length, diameter, geometric mean diameter, sphericity, thousand seed mass, volume, true density, bulk density and porosity. ...
