Potted grapevines of 140 Ruggeri (Vitis berlandieri × Vitis rupestris), a good Cl(-) excluder, and K 51-40 (Vitis champinii × Vitis riparia 'Gloire'), a poor Cl(-) excluder, and of a family obtained by crossing the two genotypes, were used to examine the inheritance of Cl(-) exclusion. Rooted leaves were then used to further investigate the mechanism for Cl(-) exclusion in 140 Ruggeri. In both ...

Leaves were sampled from Vitis labruscana Bailey cv. ‘Niagara’ and the interspecific hybrid ‘DeChaunac’ grapevines several times during a 2-year investigation of leaf area estimation. Linear measurements of leaf length and width were made and correlated with leaf area measurements made with a computerized image processing system. For each cultivar, nine regression equations were derived and com...

• Flower formation in grapevines follows 3 steps: 1) formation of uncommitted primordia, also called anlagen, within the latent buds; 2) differentiation of uncommitted primordia into inflorescence primordia; and 3) differentiation of inflorescence primordia into individual flowers . Steps 1 and 2 happen during the previous season, whereas Step 3 does not happen until budbreak of the current sea...

The molecular mechanism of aging, which has been a “black box” for many years, elucidated in recent and the nematode C. elegans, is model animal aging research, played major role its elucidation. From analysis elegans longevity-related mutant genes, signal transduction systems, with insulin/insulin-like growth factor system at core, have emerged. It become clear that this greatly affected by ex...

Caenorhabditis elegans (C. elegans) as a well-established multicellular model organism has been widely used in the biological field for half century. Its numerous advantages including small body size, rapid life cycle, high-reproductive rate, well-defined anatomy, and conserved genome, made C. one of most successful organisms. Discoveries obtained from have great contributions to research field...
