Abstract
In this review we focus on recent progress in protoplast regeneration, symmetric and asymmetric hybridization and novel technology developments. Regeneration of new species and improved culture techniques opened new horizons for practical breeding in a number of crops. The importance of protoplast sources and embedding systems is discussed. The study of reactive oxygen species effects and DNA (de)condensation, along with thorough phytohormone monitoring, are in our opinion the most promising research topics in the further strive for rationalization of protoplast regeneration. Following, fusion and fragmentation progress is summarized. Genomic, transcriptomic and proteomic studies have led to better insights in fundamental processes such as cell wall formation, cell development and chromosome rearrangements in fusion products, whether or not obtained after irradiation. Advanced molecular screening methods of both genome and cytoplasmome facilitate efficient screening of both symmetric and asymmetric fusion products. We expect that emerging technologies as GISH, high resolution melting and next generation sequencing will pay major contributions to our insights of genome creation and stabilization, mainly after asymmetric hybridization. Finally, we demonstrate agricultural valorization of somatic hybridization through enumerating recent introgression of diverse traits in a number of commercial crops.

Abstract
A fast and efficient microprojectile bombardment-mediated transformation protocol is reported for the grass species Brachypodium distachyon, a proposed alternative model plant to Oryza sativa for functional genomics in grasses. Embryogenic calli derived from immature embryos were transformed by a construct containing the uidA (coding for beta-glucuronidase) and bar (coding for phosphinothricin acetyl transferase) genes, and bialaphos, a non-selective herbicide, was used as the selection agent throughout all phases of the tissue culture. Average transformation efficiencies of 5.3% were achieved, and for single bombardments transformation efficiencies of up to 14% were observed. The time frame from the bombardment of embryogenic callus to the harvesting of transgenic T1 seeds was 29 weeks and 25 weeks for the diploid and two tetraploid accessions used, respectively. Since the seed-to-seed life cycle is 19 weeks for the diploid and 15 weeks for the tetraploid accessions, our B. distachyon transformation system allows testing of both the T0 and the T1 generation as well as production of T2 seeds within 1 year.

Abstract
Pollen is an important vector of gene flow in plants, particularly for outcrossing species like tall fescue. Several aspects of pollination biology were investigated using pollen from transgenic and nontransgenic plants of tall fescue (Festuca arundinacea Schreb.), the most important forage species worldwide of the Festuca genus. To effectively assess in vitro pollen viability in tall fescue, an optimized germination medium (0.8 mol/L sucrose, 1.28 mmol/L boric acid and 1.27 mmol/L calcium nitrate) was developed. Treatment with relatively high temperatures (36° and 40°C) and high doses of UV-B irradiation (900-1500 μW/cm(2)) reduced pollen viability, while relative humidity did not significantly influence pollen viability. Viability of pollen from transgenic progenies (T1 and T2) was similar to that from seed-derived control plants. Pollen from primary transgenics (T0) and primary regenerants (R0) had various levels of viability. Hand pollination using the primary regenerants and transgenics revealed that no seed set could be obtained when pollen viability was lower than 5%. Pollen from transgenic progenies and nontransgenic control plants could survive up to 22 h under controlled conditions in growth chamber. However, under sunny atmospheric conditions, viability of transgenic and nontransgenic pollen reduced to 5% in 30 min, with a complete loss of viability in 90 min. Under cloudy atmospheric conditions, pollen remained viable up to 240 min, with about 5% viability after 150 min. This report is the first on pollen viability and longevity in transgenic forage grasses and could be useful for risk assessment of transgenic plants.

Abstract
Monocotyledonous plants are generally more recalcitrant to genetic transformation than dicotyledonous species. The absence of reliable Agrobacterium-mediated transformation methods and the difficulties associated with the culture of monocotyledonous tissues in vitro are mainly responsible for this situation. Until recently, the genetic transformation of monocotyledons was essentially performed by direct transfer of DNA into regenerable protoplasts or intact cells cultured in vitro, via polyethylene glycol treatment, electroporation or particle bombardment. Since 1990, the use of particle gun technology has revolutionized the genetic engineering of monocotyledonous species, allowing transformation to be more independent of the in vitro culture requirements. Today, at least one genotype of each major monocotyledonous crop species, including cereals, can be genetically transformed.

Abstract
Tall fescue (Festuca arundinacea Schreb.) is a hexaploid, outcrossing grass species widely used for forage and turf purposes. Transgenic tall fescue plants were generated by biolistic transformation of embryogenic cell suspension cultures that were derived from single genotypes of widely used cultivar Kentucky-31. Primary transgenics from two genotypes, their corresponding regenerants from the same genotypes and control seed-derived plants were transferred to the field and evaluated for 2 years. Progenies of these three classes of plants were obtained and evaluated together with seed-derived plants in a second field experiment. The agronomic characteristics evaluated were: heading date, anthesis date, height, growth habit, number of reproductive tillers, seed yield and biomass. The agronomic performance of the primary transgenics and regenerants was generally inferior to that of the seed-derived plants, with primary transgenics having fewer tillers and a lower seed yield. However, no major differences between the progenies of transgenics and the progenies of seed-derived plants were found for the agronomic traits evaluated. Primary transgenics and regenerants from the same genotype were more uniform than plants from seeds. Progenies of transgenics performed similarly to progenies of the regenerants. The addition of a selectable marker gene in the plant genome seems to have had little effect on the agronomic performance of the regenerated plants. No indication of weediness of the transgenic tall fescue plants was observed. Our results indicate that outcrossing grass plants generated through transgenic approaches can be incorporated into forage breeding programs.

Abstract
Transgenic forage-type Italian ryegrass (Lolium multiflorum Lam.) plants have been obtained by microprojectile bombardment of embryogenic suspension cells using a chimeric hygromycin phosphotransferase (hph) gene construct driven by riceActl 5' regulatory sequences. Parameters for the bombardment of embryogenic suspension cultures with the particle inflow gun were partially optimized using transient expression assays of a chimericβ-glucuronidase (gusA) gene driven by the maizeUbi1 promoter. Stably transformed clones were recovered with a selection scheme using hygromycin in liquid medium followed by a plate selection. Plants were regenerated from 33% of the hygromycin-resistant calli. The transgenic nature of the regenerated plants was demonstrated by Southern hybridization analysis. Expression of the transgene in transformed adult Italian ryegrass plants was confirmed by northern analysis and a hygromycin phosphotransferase enzyme assay.

Abstract
Chimeric hygromycin phosphotransferase (hph) and phosphinothricin acetyltransferase (bar) genes were introduced, using polyethylene glycol treatment, into protoplasts isolated from embryogenic cell suspension cultures of tall fescue (Festuca arundinacea Schreb.), a graminaceous plant that is an important forage crop in temperate pastures. Colonies resistant to either 200 mg/l hygromycin or 100 mg/l phosphinothricin, respectively, were recovered upon selection using bead-type culture systems. Stable integration of the transgenes in the genomes of plants regenerated from resistant callus clones was shown by Southern hybridization analysis. In situ hybridization of a labeled transgene-probe to metaphase chromosomes is shown for one transgenic primary regenerant. Expression of the transgenes in mature plants was demonstrated by HPH enzyme assay or by phosphinothricin-herbicide spraying.

Abstract
Embryogenic maize (Zea mays L.) callus cultures were transformed by microprojectile bombardment with a chimeric hygromycin phosphotransferase (HPT) gene and three transformed lines were obtained by selecting for hygromycin resistance. All lines contained one or a few copies of the intact HPT coding sequence. Fertile, transgenic plants were regenerated and the transmission of the chimeric gene was demonstrated through two complete generations. One line inherited the gene in the manner expected for a single, dominant locus, whereas two did not.

Abstract
We have developed a method for reproducibly obtaining transgenic rice at a high frequency (10(-4)): electroporation with a buffer in which chloride ions are replaced with organic acids. Co-transformation frequencies of the β-glucuronidase (GUS) and hygromycin phosphotransferase (HPT) genes located on two separate plasmids were higher than 50%. Transgenic rice plants contained multiple copies of introduced genes integrated into their genomes in a complex manner. GUS enzyme activity was not proportional to gene copy number. Introduced HPT genes were detected and expressed in the progeny of transformants.

Abstract
Embryogenic suspension cultures of cotton (Gossypium hirsutum L.) were subjected to particle bombardment, where high density particles carrying plasmid DNA were accelerated towards the embryogenic plant cells. The plasmid DNA coating the particles encoded hygromycin resistance. One to two weeks following bombardment, embryogenic cotton cells were placed in proliferation medium containing 100 μg/ml hygromycin. Clumps of tissue which grew in the presence of hygromycin were subcultured at low density into fresh hygromycin-containing proliferation medium. Following sequential transfer of embryogenic tissue to development and then germination media, plants were recovered from transgenic embryogenic tissue. Southern hybridization confirmed the presence of the hygromycin resistance gene in embryogenic suspension culture tissue and regenerated plants.
