Plant Growth Modeling of Zinnia Elegans Jacq Using Fuzzy Mamdani and L-system Approach with Mathematica
Modeling of the plant growth can be visualized using the approach of Lindenmayer System (L-System). This L-System models the plants growth by following the production rules, which are the combination of grammar and mathematic formulae. In this paper, we propose the use of fuzzy mamdani, to model the plant growth based on the current environment condition. The varied amount of fertilizer, both o...
متن کاملScientific Correspondence Zinnia. Everybody Needs Good Neighbors
Cells in an organism exist within a social context— the sum of interactions with neighboring cells help to define the nature of each individual. The Zinnia system provides a unique opportunity to study in vitro the interactions between different plant cell types and the consequences for commitment to a particular cell fate. Zinnia is a model system in which mesophyll cells, released from young ...
متن کاملCell Expansion and Tracheary Element Differentiation Are Regulated by Extracellular pH in Mesophyll Cultures of Zinnia elegans L.
The effects of medium pH on cell expansion and tracheary element (TE) differentiation were investigated in differentiating mesophyll suspension cultures of Zinnia elegans L. In unbuffered cultures initially adjusted to pH 5.5, the medium pH fluctuated reproducibly, decreasing about 1 unit prior to the onset of TE differentiation and then increasing when the initiation of new Tes was complete. E...
متن کاملAn alternative methylation pathway in lignin biosynthesis in Zinnia.
S-Adenosyl-L-methionine:trans-caffeoyl-coenzyme A 3-O-methyltransferase (CCoAOMT) is implicated in disease resistant response, but whether it is involved in lignin biosynthesis is not known. We isolated a cDNA clone for CCoAOMT in differentiating tracheary elements (TEs) induced from Zinnia-isolated mesophyll cells. RNA gel blot analysis showed that the expression of the CCoAOMT gene was marked...
متن کاملImaging cell wall architecture in single Zinnia elegans tracheary elements.
The chemical and structural organization of the plant cell wall was examined in Zinnia elegans tracheary elements (TEs), which specialize by developing prominent secondary wall thickenings underlying the primary wall during xylogenesis in vitro. Three imaging platforms were used in conjunction with chemical extraction of wall components to investigate the composition and structure of single Zin...
