چکیده

Vascular plants produce new organs at the tip of the stem in a very organized fashion. This patterning process occurs in small groups of stem cells, the so-called shoot apical meristems (SAM), and generates regular patterns called phyllotaxis. The phyllotaxis of the model plant Arabidopsis thaliana follows a Fibonacci spiral, the most frequent phyllotactic pattern found in nature. In this phyllotactic mode, single organs are initiated successively at a divergence angle from the previous organ close to 137.5°, the golden angle.

Yeast Two Hybrid cDNA Screening of Arabidopsis thaliana for SETH4 Protein Interaction

SETH4 coding sequence with 2013 bp is a member of gene family expressed in gametophytic tissues of Arabidopsis thaliana. This fragment was PCR amplified using Kod Hi Fi DNA polymerase enzyme. This fragment was cloned into pGBKT7 bate vector and transformed E. coli DH5? cells containing vector were selected on LB medium containing Kanamycin. Finally, pGBKT7-SETH4 bate was transformed into yeast ...

Negative control of Strictisidine synthase like-7 gene on salt stress resistance in Arabidopsis thaliana

Strictosidine synthase-like (SSL) is a group of gene families in the Arabidopsis genome, which whose orthologues in other plants are key enzymes in mono-terpenoid indole-alkaloid biosynthesis pathway. The SSL7 is upregulated upon treatments of Arabidopsis plants with signaling molecules such as SA, methyl jasmonate and ethylene. To find the functional role of the gene, a T-DNA-mediated knockout...

Functional analysis of glycin rich- RNA binding protein, a suppressor of trehalose-6-phosphate mediating growth arrest in Arabidopsis thaliana

Metabolism of the alpha-1,1 glucose disaccharide, trehalose, is indispensable in plants. In the Murashigeand Skoog (MS) medium, trehalose inhibits plant growth and allocation of carbon to roots. A suppressorof trehalose-6-phosphate (T6P) mediated growth arrest, GR-RBP2, is characterized in more detail.Phylogenetic analysis revealed that GR-RBP2 is a protein of likely prokaryot...

Differential Expression of Arabidopsis thaliana Acid Phosphatases in Response to Abiotic Stresses

The objective of this research is to identify Arabidopsis thaliana genes encoding acid phosphatases induced by phosphate starvation. Multiple alignments of eukaryotic acid phosphatase amino acid sequences led to the classification of these proteins into four groups including purple acid phosphatases (PAPs). Specific primers were degenerated and designed based on conserved sequences of PAPs isol...

Meristem identity and phyllotaxis in inflorescence development

Inflorescence morphology is incredibly diverse. This diversity of form has been a fruitful source of inquiry for plant morphologists for more than a century. Work in the grasses (Poaceae), the tomato family (Solanaceae), and Arabidopsis thaliana (Brassicaceae) has led to a richer understanding of the molecular genetics underlying this diversity. The character of individual meristems, a combinat...
