Actin cables in pollen tubes serve as molecular tracks for cytoplasmic streaming and organelle movement and are formed by actin bundling factors like villins and fimbrins. However, the precise mechanisms by which actin cables are generated and maintained remain largely unknown. Fimbrins comprise a family of five members in Arabidopsis thaliana. Here, we characterized a fimbrin isoform, Arabidop...

to answer this question that if osmopriming improve germination indices in salinity-affected seeds of pinus eldarica medw., a factorial experiment in randomized completely design was carried out with three replications. osmotic treatments were applied in 5 levels (-2, -4, -6 and -8 bar for 72 hours and non-primed) by polyethylene glycol (peg) and salinity treatments in 8 levels (0, 40, 80, 120,...

in order to evaluation the effect of drought stress on germination indices and early seedling growth of medicinal herb dill (anethum graveolens l), an experiment was conducted in the agricultural laboratory of urmia payam noor university in 2015 as a randomized complete block design with four replications. treatments were five levels of drought stress (0, -1, -2, -3 and -4 bar induced by polyet...

a lack of adequate annual chilling in temperate zone fruit growing trees, especially pistachio is a main problem observed in many areas with partly warm winters. usually this phenomenon results in disorders in vegetative and reproductive structures, decrease in production of pollen, falling of flower buds and decrease in or loss of fruit set. presently the use of some substitute chemical compou...

Priming fresh and naturally aged canola seeds with different substances observing the seed germination properties are involved in this work. Fresh of cv. “süzer” were treated distilled water, -0.8 MPa polyethylene glycol (PEG) 6000 50 mM thiamine for 8 hours. Storage showed loss capacity compared to seeds. Present findings indicate that priming can improve speed both canola. Germination percent...

background and objectives: the most important determining factor in sugar beet root yield is seed quality. seeds with germination percentage are lower; the germination is slow and non-uniform, will produce plants that initial growth is slow. according to various studies indicate that harvest time is an important factor influencing the quality of sugar beet seed. in the early harvest of sugar be...

The structural characteristics of a spore enable it to withstand stresses that typically kill a vegetative cell. Spores remain dormant until small molecule signals induce them to germinate into vegetative bacilli. Germination requires degradation of the thick cortical peptidoglycan by germination-specific lytic enzymes (GSLEs). Bacillus anthracis has four putative GSLEs, based upon sequence sim...

Non-native earthworms have invaded ecosystems around the world but have recently received increased attention as they invaded previously earthworm-free habitats in northern North America. Earthworms can affect plants by ingesting seeds and burying them in the soil. These effects can be negative or positive but are expected to become increasingly negative with decreasing seed size. Orchids have ...

to determine the effect of seed size of sugar beet cultivars on germination and seedling vigor, a study was conducted as a 4×6 factorial experiment based on completely randomized design with 4 replications at seed and plant certification and registration institute, karaj in 2013. the treatments were toucan, dorotea, rasta, sharif, pars, and torbat cultivars and four seed width sizes including 2...
