Introgression of Genes by Wide Hybridization: a Crop Improvement Approach
Introgression is the movement of genes or gene flow from one species into the gene pool. wide hybridisation breaks the species barrier for gene transfer and makes it possible to transfer the genome of one species to other, which results alteration in genotypes and phenotypes of the progeny. The main objective of wide hybridisation is to transfer desirable genes, to create genetic variability wh...
متن کامل"Experiments in Plant Hybridization" (1866), by Johann Gregor Mendel
During the mid-nineteenth century, Johann Gregor Mendel experimented with pea plants to develop a theory of inheritance. In 1843, while a monk in the Augustian St Thomas?s Abbey in Brünn, Austria, now Brno, Czech Repubic, Mendel examined the physical appearance of the abbey?s pea plants ( Pisum sativum [4]) and noted inconsistencies between what he saw and what the blending theory of inheritanc...
متن کاملImprovement of Rooting in Forsythia × intermedia Cuttings by Plant Growth Regulators
Asexual propagation through cuttings is an appropriate method used for most ornamental plants. Success in increasing the percentage of rooting, reducing root emergence and increasing proliferation efficiency depends on several factors like plant growth regulators, especially auxins. Rooting of Forsythia × intermedia is difficult and requires specific hormonal treatments and proper cultivation b...
متن کاملImprovement of petroleum hydrocarbon remediation using the oat plant in the soil treated by poultry manure
This greenhouse experiment aimed to investigate the effects of poultry manure (PM) on the growth of oat plant (Avena sativa) and removal of total petroleum hydrocarbons (TPHs) from soil. The treatments consisted of three TPH levels (4%, 6%, and 8% w/w) and two PM levels (zero and 1%) at three replications. According to the findings, shoot height, number of leaves, and the fresh and dry...
متن کاملSubunit hybridization of higher plant lactate dehydrogenases
developed a procedure, based on the affinity of all three enzymes for Cibacron Blue 3GA, which allows their simultaneous purification from a cell extract. E. coli K 12, EMG-2 was grown, harvested and disrupted as described by Miller & Stadtman (1972). After treatment with 1% (w/v) streptomycin sulphate, the cell extract was subjected to ammonium sulphate fractionation. The protein fraction prec...
