Root organization and gene expression patterns
نویسندگان
چکیده
New tools of microscopy, molecular biology, and genetics are making it possible for biologists to study roots with new vigour. Such investigations have enabled plant biologists to notice the symmetry, pattern, and simplicity of root structures so that there is now an exciting rebirth in the study of roots. The literature of root biology, development and structure is vast. In this short review we will concentrate on describing our notion of how roots are organized structurally, and then discuss what is known about tissueand zone-specific gene expression in roots.

Expression pattern analysis of TomPRO2 and LaPA1 genes in tomato under in vitro salt stress by Semi-quantitative RT-PCR
The expression pattern of TomPRO2 and LaPA1 genes in two tomato (Lycopersicon esculentum) cultivars named as Isfahani and Shirazi under in vitro salt stress were investigated. Four to six weeks old in vitro grown seedlings were transferred on MS medium containing 0, 80 and 160 mM NaCl and untreated plants were used as control. RNA was extracted from root and leaf and then cDNA was synthesized. ...
متن کاملPrimary root growth, tissue expression and co-expression analysis of a receptor kinase mutant in Arabidopsis
There is no functional annotation for the majority of the several hundreds of receptor-like kinases in plants. A direct way of inferring the function of these proteins is to study the phenotype that results from loss of function mutants such as T-DNA mutant lines. In this research a function (phenotype) to At2g37050 gene that encodes a receptor like kinase in Arabidopsis T-DNA line was...
متن کاملGSTF1 Gene Expression Analysis in Cultivated Wheat Plants under Salinity and ABA Treatments
Most plants encounter stress such as drought and salinity that adversely affect growth, development and crop productivity. The expression of the gene glutathione-s-transferases (GST) extends throughout various protective mechanisms in plants and allows them to adapt to unfavorable environmental conditions. GSTF1 (the first phi GSTFs class) gene expression patterns in the wheat cultivars Mahuti ...
متن کاملMicroarray analysis of gene expression patterns in Arabidopsis seedlings under trehalose, sucrose and sorbitol treatment
Trehalose is the non-reducing alpha-alpha-1, 1-linked glucose disaccharide. The biosynthesisprecursor of trehalose, trehalose-6-phosphate (T6P), is essential for plant development, growth,carbon utilization and alters photosynthetic capacity but its mode of action is not understood. In thecurrent research, 6 days old seedlings of Arabidopsis thaliana (Columbia ecotype) were grown inliquid cultu...
متن کاملO-41: Comparison of Vitrification Systems inHuman Oocytes and Evaluation of HSP A1Aand MnSOD Gene Expression Patterns
Background: The aim of this study was to compare two vitrification systems (Cryotop and OPS) on mouse MII oocytes and evaluate its effects on expression of heat shock protein A1A and MnSOD genes. Materials and Methods: Groups of about 15 oocytes without cumulus complexes (granulose, et. al.) were collected and exposed to equilibration and vitrification solutions before loading the oocytes into ...

Background: To screen and diagnose patients with recurrent abortions and implantation failure after IVF/ICSI, differentially expressed genes of endometrium through DNA microarrays were monitored. Materials and Methods: Microarray expression profile of GSE26787 dataset from GEO database was used to analyze gene expression profiles of 15 endometrial biopsy samples- five from control fertile (CF) ...
