Total proteins, esterases and acid phosphatases from pollen, seeds and leaves of three sunflower cultivars were separated by 2-D electrophoresis. The characteristic peptides for each cultivar were identified. The seeds and pollen of the cultivar Wielkopolski contained 45 and 37 characteristic peptides, respectively, while the seeds and pollen of Coril contained 73 and 35 characteristic peptides...

The availability of soybean mutants with altered symbiotic properties allowed an investigation of the shoot or root control of the relevant phenotype. By means of grafts between these mutants and wild-type plants (cultivar Bragg and Williams), we demonstrated that supernodulation as well as hypernodulation (nitrate tolerance in nodulation and lack of autoregulation) is shoot controlled in two m...

Elettaria cardamomum (L.) Maton, or small cardamom referred as 'queen of spices', is a perennial herbaceous rhizomatous monocot of the family Zingiberaceae. Cardamom seeds and fruits are the economically significant parts and effectively used as a traditional medicine, food additive and flavoring agent. In the present study, using Ion Proton next generation sequencing technology we performed th...

Using two lowland rice (Oryza sativa L.) cultivars we found that in both cases submerged-induced elongation early after germination depends on gibberellins (GAs). Submergence increases the content of the active GA 1 by enhancing the expression of GA biosynthesis genes, thus facilitating the seedlings to escape from the water and preventing asphyxiation. However, the two cultivars differ in thei...

The present study examined free-radical scavenging enzyme activity and the levels of lipid peroxide, ascorbic acid, nitric oxide and glutathione in 1616C rootstock and the Razaki cultivar of Vitis vinifera L. under treatment with different concentrations of salt. At day 7, in leaves of both 1616C rootstock and cv. Razaki treated with 12 mM NaCl there were significant increases in glutathione pe...

Salt stress inhibits soybean growth and reduces gain yield. Genetic improvement of salt tolerance is essential for sustainable soybean production in saline areas. In this study, we isolated a gene (Ncl) that could synchronously regulate the transport and accumulation of Na(+), K(+), and Cl(-) from a Brazilian soybean cultivar FT-Abyara using map-based cloning strategy. Higher expression of the ...

Effect of five NaCl salinity treatments (0, 50, 100, 200 and 300 mM) given at different growth and developmental stages on total N level and in vitro nitrate reductase activity (NRA) in leaves and roots of two wheat cultivars viz., Ghods and Boolani was studied in greenhouse conditions. In response to salinity treatments, total N concentrations and NO3 assimilation rates in Ghods, a saltsensiti...

We investigated the regeneration of two Bulgarian sweet pepper cultivars (‘Hebar’ and ‘Stryama’) on solid and liquid culture medium. Liquid cultures were incubated in temporary immersion RITA ® airlift bioreactors. During a period of 60 days, culture in the liquid medium was associated with significantly increased shoot tip growth, number of lateral shoots, percentage of rooted plants and micro...

The aim of the research was to determine field, greenhouse and seed bed performance of plantlets derived from in vitro propagated plantlets of three potato cultivars. Generally, higher values were obtained from the mid-early maturing cultivar Marabel, compare to other cultivars (early cultivar Velox and and mid-early cultivar Concorde) for tuber yield, tuber number and average tuber weight. For...

Manganese superoxide dismutase (Mn-SOD) plays a crucial role in antioxidant responses to environmental stress. To determine whether Mn-SOD affects heat resistance of Gracilaria lemaneiformis, we cloned Mn-SOD cDNA sequences of two strains of this red alga, wild type and cultivar 981. Both cDNA sequences contained an ORF of 675 bp encoding 224 amino acid residues. The cDNA sequences and the dedu...
