Abstract:
Protoplast culture (protoplast fusion) is one method of tissue culture that is widely used in plant breeding programs in a relatively short time. This method is used to overcome the problem of plants that are difficult or impossible to cross conventionally as well as used for species improvement by transferring the desired gene from the donor plant to the target plant via protoplast fusion. Protoplast fusion makes it possible to produce plants that are resistant to a disease and various abiotic stresses, rapid growth rates and have a better quantity and quality of metabolites than their parents. Various factors affect the success of fusion and regeneration of protoplasts into whole plants, including the source of explants, the composition of the enzyme solution and the duration of incubation, fusagen type and culture media for regeneration.

Abstract:
Biotechnology strategies are now available to improve the amount and availability of nutrients in plant crops. Those strategies include simple plant selection for varieties with high nutrient density in the seeds, cross-breeding for incorporating a desired trait within a plant, and genetic engineering to manipulate the nutrient content of the plant. In plant cross-breeding, all genes of the parent plants are combined and the progeny have both desirable and undesirable traits. To eliminate undesirable traits, plant breeders «back-cross» the new plant varieties with other plants over several generations. This technique, called hybridization, has been used to create varieties of low-phytate corn, barley, and rice. Using the techniques of genetic engineering, the gene(s) encoding for a desired trait(s) in a plant are introduced in a precise and controlled manner within a relatively short period of time. Golden rice, containing carotenoids, and rice with higher amounts of iron, are two examples of genetically engineered plants for improved nutrition. Genetic engineering has tremendous potential for revolutionizing nutrition. However, public concerns regarding safety, appearance, and ethics must be overcome before these products can be effectively introduced into the food supply.

Abstract:
Heritable variation is at the heart of the process of evolution. However, variation is restricted in breeding for uniform crop populations using the pedigree line approach. Pedigree lines are successful in agriculture because synthetic inputs are used to raise fertility and control weeds, pests and diseases. An alternative method promoted for exploring the value of variation and evolutionary fitness in crops is to create composite cross populations. Composite cross populations are formed by assembling seed stocks with diverse evolutionary origins, recombination of these stocks by hybridization, the bulking of F1 progeny, and subsequent natural selection for mass sorting of the progeny in successive natural cropping environments. Composite cross populations can provide dynamic gene pools, which in turn provide a means of conserving germplasm resources: they can also allow selection of heterogeneous crop varieties. The value of composite cross populations in achieving these aims is dependent on the outcome of mass trials by artificial and natural selection acting upon the heterogeneous mixture. There is evidence to suggest that composite cross populations may be an efficient way of providing heterogeneous crops and of selecting superior pure lines for low input systems characterized by unpredictable stress conditions.

Abstract:
The rapid identification of sex in the dioecious hop (Humulus lupulus) is important for the breeding of this cultivated plant because only unfertilized flowers of the female plants are used as an ingredient in the production of beer. It is thought that a sex-chromosome mechanism controls the development of male or female plants. We have compared pools of male and female plants derived from a hop cross to identify molecular markers associated with the Y or male-specific chromosome. Of 900 functional RAPD primers, 32 revealed fragments specific for male plants that were absent in female plants of this cross. Subsequently, the 32 positive primers were tested on unrelated male and female plants. Three of these 32 primers were specific for the Y chromosome in all lines. The Y-specific product derived from one of these primers (OPJ9) was of low copy in hybridization experiments and predominantly present in male plants. Primers developed from the DNA sequence of this product provide a marker for rapid sex identification in crosses of hop by means of PCR.Key words: chromosomes, RAPD, sex-specific DNA sequences, plant breeding, Y chromosome.

Abstract:
DNA-based diagnostics are now well-established as a means to assay diversity at the locus, chromosome, and whole-genome levels. As technology has advanced, DNA sequence-based assays have become easier to use, more efficient at screening for nucleotide sequence-based polymorphisms, and available to a wider cross-section of the research community. A review of the use of molecular markers in several different areas of genetics and plant breeding will be presented, as well as a discussion about their advantages and limitations. Recent advances in several areas of technology development and laboratory automation will also be presented, including a summary of direct comparison of different DNA marker systems against a common set of soybean cultivars.

Abstract:
A Multi-parent Advanced Generation Intercross (MAGIC) tomato population was developed by crossing eight founder lines chosen to include a wide range of variability. The lines were previously genotyped by a genotyping by sequencing approach. The MAGIC population was used to develop genotypes with important agronomic traits and to perform the Participatory Plant Breeding (PPB). Among the 400 plants of generation 4 (G4) of the MAGIC population cultivated in an organic field experiment, 22 individuals were phenotypically selected and a molecular analysis was done for both presence of resistance genes and fruit shape (marker assisted selection) on G5 seedlings. Three selected plants showed both the pyramiding gene of resistance to the main diseases and the ovate gene for pear shape typology. The 400 G10 stable lines that obtained from single seed descent will represent an important genetic resource for the tomato scientific community. The MAGIC population G4 was also cultivated in three organic farms located in North, Central and South Italy to carry out the PPB. The plants showed significant phenotypic differences in development, productivity and fruit color. This variability was used to select families of tomato adapted to low input crop management, different environments, agricultural practices and market conditions.

Abstract:
Abstract Uniparental genome elimination (UGE) refers to the preferential exclusion of one set of the parental chromosome complement during embryogenesis following successful fertilization, giving rise to uniparental haploid progeny. This artificially induced phenomenon was documented as one of the consequences of distant (wide) hybridization in plants. Ten decades since its discovery, attempts to unravel the molecular mechanism behind this process remained elusive due to a lack of genetic tools and genomic resources in the species exhibiting UGE. Hence, its successful adoption in agronomic crops for in planta (in vivo) haploid production remains implausible. Recently, Arabidopsis thaliana has emerged as a model system to unravel the molecular basis of UGE. It is now possible to simulate the genetic consequences of distant crosses in an A. thaliana intraspecific cross by a simple modification of centromeres, via the manipulation of the centromere-specific histone H3 variant gene, CENH3. Thus, the experimental advantages conferred by A. thaliana have been used to elucidate and exploit the benefits of UGE in crop breeding. In this review, we discuss developments and prospects of CENH3 gene-mediated UGE and other in planta haploid induction strategies to illustrate its potential in expediting plant breeding and genetics in A. thaliana and other model plants.
