Autumn sowing of sugar beet is a suitable way in sustainable agriculture. Bolting is an undesirable phenomenon which reduces sugar beet yield and it is the most important limiting factor in autumn sowing of sugar beet. Identification and comparison of the sequence of flowering genes in various genotypes can help to understand the molecular mechanisms controlling bolting. In the previous studies...

Ethylene is a major plant hormone that plays an important role in regulating bolting, although the underlying molecular mechanism is not well understood. In this study, we report the novel finding that the serine-62 (Ser-62) phosphorylation of Ethylene Response Factor110 (ERF110) is involved in the regulation of bolting time. The gene expression and posttranslational modification (phosphorylati...

Bolting and flowering are key processes during the growth and development of Chinese cabbage (Brassica rapa L. ssp pekinensis). Understanding the molecular mechanisms underlying bolting and flowering is of significance for improving production of the vegetable. A leaf-color change from bright green to gray-green has been observed following differentiation of the flowering stem and before boltin...

Many plant species in temperate climate regions require vernalization over winter to initiate flowering. Flowering Locus C (FLC) and FLC-like genes are key regulators of vernalization requirement and growth habit in winter-annual and perennial Brassicaceae. In the biennial crop species Beta vulgaris ssp. vulgaris in the evolutionarily distant Caryophyllales clade of core eudicots growth habit a...

The National Institute for Occupational Safety and Health (NIOSH) at the Pittsburgh Research Laboratory (PRL) is conducting research to reduce the noise exposures of roof bolting machine operators and to prevent additional cases of Noise Induced Hearing Loss (NIHL) thru the development of engineering noise controls. This paper describes and evaluates an engineering noise control for the roof bo...

The surrounding rock of deep roadway is mostly composed fractured rock. deformation complicated, which not only involves the stress change, but also support means. This paper aims to study and fracture evolution law in underground engineering. According rebalancing characteristics, after excavation, development characteristics cracks are studied. At same time, different seepage zones divided ac...

Onion (Allium cepa L.) is one of the important vegetable crops in the world, usually with a two-year life cycle. The bulbs form in the first year after sowing, then bolting and flowering are induced by low temperature in the following year. Previous studies have shown that LEAFY gene is an inflorescence tissue specific gene, and that it is also the ultimate collection channel of all flowering p...

in order to determine the optimum sowing and harvesting dates of two autumn sugar beet cultivars (bete vulgaris l.) and develop the planting area of this crop, the present research was conducted in fasa, iran during 2005-2008. the experiment was carried out in split-split plots based on randomized complete block design (rcbd) with four replications. three sowing dates (september 27, october 17 ...

Abstract The drilling operation in the roof bolting process, especially hard rock, generates excessive respirable coal and quartz dusts, which could expose operator to continued health risks. Previous research has shown that amount of dust produced is dependent on main parameters, specifically rotational penetration rate. In this paper, a bolter control process was proposed reduce generation du...
