“…These exogenous amino acids and peptides have been applied as plant growth-stimulating materials. 11,17,18) It is possible that the structure of the bluegill peptide(s) differs from previously reported peptides; therefore, it might also function in a different manner in plants. Analysis of its uptake and mechanism of activation is therefore of interest, and in the future, the aim is to determine the activity of a combination of these peptides and amino acids on plant growth, thus helping to develop new plant growth-promoting materials.…”

“…Photos were then analyzed using Photoshop 5.0 (Adobe Systems, San Jose, CA) and root hair density was evaluated according to the darkness of the picture: root hair density = 255 À the brightness (values of 255 and 0 represent black and white respectively). 18,19) Analysis of adventitious root formation. Adventitious root formation was analyzed using Lycopersicon esculentum (Takii Syubyou, Kyoto).…”

One of the prime pre cur sor for eth yl ene syn the sis -L-methionine and the in hib i tor of 1-aminocyclopropane-1-carboxylic acid oxidase (ACO) -Co 2+ -were tested for their ef fects on sex ex pres sion and de vel op ment of Ane mia phyllitidis fern gametophytes. Five con cen tra tions of both chem i cals (0, 10, 25, 50, 100 µM) were ana lysed with ref er ence to antheridia and archegonia for ma tion, num ber and size of cells as well as thalli length us ing the three-zone model of gametophyte struc ture. Both sub stances, how ever at dif fer ent con cen tra tions, enhanced the num ber of GA 3 -in duced antheridia and sim i larly stim u lated the cell num ber and in hib ited thalli length. Both of them at 100 µM con cen tra tions with out GA 3 in duced meristematic area for ma tion while methionine also in duced archegonia in the api cal parts of gametophytes.
