Methods to Create Marker Gene-Free Transformed Plants | Genetics

Four main methods have been suggested to create marker gene-free transformed plants. The methods are: 1. Co-Transformation 2. Site-Specific Recombination 3. Marker Gene Elimination by Transposase 4. Marker Gene Elimination by Intrachromosomal Recombination. Method # 1. Co-Transformation: Co-transformation strategies are popularly employed for the production of transformed plants free from marker gene(s). In this novel approach, gene of interest and [...]

Gene Expression Profiles in Response to Stress | Genetics

In this article we will discuss about the gene expression profiles in response to stress. Microarray technology has been the useful tool for analyzing gene expression pattern in stressed plants. Full-length cDNA microarray analysis identified 44 drought-inducible genes. Fourteen of these genes were reported to be drought-inducible genes, such as rd 29A/cor 78, cor 15a, kin 1, kin 2, rd [...]

Production of Osmo-Protective Compounds | Genetics

In this article we will discuss about the production of osmo-protective compounds. Plants exhibit certain degree of defences against various environmental stresses by producing various osmoprotectants (Table 15.1). Accumulation of osmoprotectants and osmolytes like quarternary amines, amino acids and sugar alcohols increases their stress tolerance. Stress tolerant plants accumulating such compounds are more effective in tackling stress problem than others. [...]
