to evaluate general and specific combining ability for resistance to bolting and cercospora leaf spot, 36 hybrids derived from crosses between 9 sugar beet lines along with four checks were planted in safiabad agricultural research center (dezful) in 2008-2009. the experimental design was a triple lattice design with three replications. analysis of variance showed significant differences among ...

LFYgene plays important roles in determining plant flowering mainly by controlling the timing of phase transition. Constitutive under-expression of LFY gene in Arabidopsis resulted in the formation of late flowering and highly branching phenotype. In this paper, we investigated some physiological and biochemical properties of the transformantsthat were down-regulated LFY gene expression to dela...

This research was conducted to evaluate the effect of temperature and photoperiod treatments on the bolting and bulb formation of three local garlic cultivars (cvs) in two consecutive years. Naturally vernalized plants of cvs G107, G025 and G064 were transplanted into growth chambers and subjected to various combinations of temperature [T15/10, 15°C/10°C; T20/15, 20°C/15°C and T25/18, 25°C/18°C...

We recently described the glucosinolate transporters GTR1 and GTR2 as actively contributing to the establishment of tissue-specific distribution of the defense compounds glucosinolates in vegetative Arabidopsis plants. Upon bolting and thereby development of the inflorescence and initiation of seed setting, the spatial distribution of glucosinolates does undergo major changes. Here we investiga...

Cytosolic NADPH can be directly oxidized by a calcium-dependent NADPH dehydrogenase, NDB1, present in the plant mitochondrial electron transport chain. However, little is known regarding the impact of modified cytosolic NADPH reduction levels on growth and metabolism. Nicotiana sylvestris plants overexpressing potato (Solanum tuberosum) NDB1 displayed early bolting, whereas sense suppression of...

Among underground coal miners, hearing loss remains one of the most common occupational illnesses. To address this problem, the U.S. National Institute for Occupational Safety and Health Office of Mine Safety and Health Research (NIOSH OMSHR) conducts research to reduce the noise emission of underground coal mining equipment, an example of which is the roof bolting machine. Field studies show t...

autumn planting of sugar beet as compared to its spring cultivation demands less application of water in semi-arid region such as iran. therefore, cultivation of sugar beet in autumn is considered as a better choice to be benefited from autumn and winter precipitation and escaping from water deficit crises. in two areas of aran-o-bidgol, esfahan (ae) and izeh, khuzestan (ik), two independent ex...

Chinese cabbage (Brassica rapa L.) is one of the most important and highly nutritious vegetables in China belonging to Brassicaceae family. Flowering or bolting critical developmental stages flowering plants. For spring-sown cabbage, late-bolting desirable over early-bolting according consumer preferences. We determined inheritance pattern trait using F1 F2 generated from a cross between ‘SY200...
