Opis:: The discovery of conifer somatic embryogenesis (SE) and the subsequent development of SE protocols for a range of genera and species have opened new research opportunities to forest biotechnologists and a means towards mass clonal propagation for the forest industry. This paper provides a general description of the conifer SE process, followed by a review of protocols developed specifically for several conifer species in the Pinaceae family for which production of somatic trees has been demonstrated. Additionally, future research needs, including approaches for developing markers to optimize SE process and the production of high quality embryos, are discussed.

Opis:: Somatic embryogenesis (SE) of conifers for clonal propagation has emerged from its earliest beginnings in 1980 to become an integral component of tree improvement strategies. With its capacity for long-term germplasm preservation and scale-up technologies,it is seen to be the preferred avenue to accelerate selection and operational deployment of value-added genotypes. At present,programs for numerous species from the Pinaceae family are underway worldwide,with activities ranging from selection trials to pilot production for plantation forestry. This paper will provide a review of current efforts in conifer SE including cryopreservation,commercialization and deployment strategies,and transgenics. A discussion of challenges and issues is directed at genetic fidelity, intellectual property and future needs.

Opis:: Somatic embryogenesis is the latest, and potentially the most efficient, method for the vegetative micropropagation of plants. Over the past three decades, numerous laboratory studies have investigated somatic embryogenesis of forest trees, yielding positive results for a number of economically important tree species. The first test trials were run and plantations were planted with interior spruce in the 90s by CellFor Inc. (Canada). However, at the beginning of the XXI century, the program to produce spruce and Douglas fir somatic seedlings was stopped for economic reasons. Thus, currently no operational program is ongoing except on a small scale in New Brunswick. In order to integrate somatic embryogenesis technology into operational reforestation programs, the production costs of forest tree somatic seedlings needs to be reduced, and the awareness of foresters and forest landowners that the material obtained through somatic embryogenesis is valuable needs to be increased. This awareness would enable implementation of this technology on a large scale for production and forest management throughout Europe including Poland. In this review, the importance of somatic embryogenesis in scientific research and in global and European forestry is presented. Our main aims are to provide basic information on the challenges in researching somatic embryogenesis of forest trees and to raise interest in this tree propagation technique in both scientists and foresters.

Opis:: The potential of immature zygotic embryos to produce embryogenic tissue was tested using culture media differed in inorganic salt composition as well as plant growth regulator content. Explants cultured on DCR as well as MLV media gave the highest initiation percentages with maximum values of 8.8% (MLV) to 10.4% (DCR). Plant growth regulators content (standard or reduced) had no profound effect on embryogenic tissue initiation. Somatic embryo maturation as well as germination was dependent on the cell line and salt composition of the medium. Plantlet regeneration occurred in three cell lines out of five tested. During the maturation process profound changes occurred in the internal organisation of somatic embryos such differentiation of root meristem in precotyledonary somatic embryos and formation of provascular strands in cotyledonary somatic embryos.

Opis:: Somatic seeds of Plantago asiatica L. were produced for the first time. Shoot-tips isolated from in vitro obtained 4-week shoots were encapsulated using sodium alginate and calcium chloride. Capsules with or without sucrose and with and without cytokinin - indole-3-butyric acid (IBA) were used. Sucrose presence in capsules very distinctly influences somatic seeds of Plantago asiatica germination and their conversion into plants. However, addition of IBA to capsules has not clear influence on the ability of plant regrowth. Plantlets transplanted to soil grew to phenotypically normal plants.

Opis:: The studies were carried out on seed explants (mature zygotic embryos) of four spruce species: Picea omorika (Pancić) Purk., P. pungens ‘Glauca' Beisnn., P. breweriana S. Watson and P. abies (L.) Karst. The explants required darkness during the induction of embryogenic tissue. Temporary exposure of explants to light did not increase their embryogenic capacity. It was observed that the temperature of 25°C was the optimal for embryogenic tissue induction from mature zygotic embryos of Picea omorika. Cold treatment at 4°C during one week improved embryogenic tissue initiation in the explants of P. pungens ‘Glauca'. Seed explants of Picea omorika produced embryogenic tissue on medium lacking glutamine. Only explants of Picea abies and P. omorika showed embryogenic tissue formation. For effective proliferation of embryogenic tissue in Picea abies and P. omorika it was necessary to supply the medium with 2,4-D (4.5-9 μM) and BA (2.25 μM). Two of three analized lines showed that ABA promote somatic embryo maturation, at the ABA concentration 20 μM in the medium.

Opis:: Embryogenic cultures of plants are exposed to various stress factors both in vitro and during cryostorage. In order to safely include the plant material obtained by somatic embryogenesis in combination with cryopreservation for breeding programs, it is necessary to monitor its genetic stability. The aim of the present study was the assessment of somaclonal variation in plant material obtained from embryogenic cultures of Picea abies (L.) Karst. and P. omorika (Pančić) Purk. maintained in vitro or stored in liquid nitrogen by the pregrowth-dehydration method. The analysis of genetic conformity with using microsatellite markers was performed on cotyledonary somatic embryos (CSE), germinating somatic embryos (GSE) and somatic seedlings (SS), obtained from tissues maintained in vitro or from recovered embryogenic tissues (ETc) and CSE obtained after cryopreservation. The analysis revealed changes in the DNA of somatic embryogenesis-derived plant material of both Picea spp. They were found in plant material from 8 out of 10 tested embryogenic lines of P. abies and in 10 out of 19 embryogenic lines of P. omorika after in vitro culture. Changes were also detected in plant material obtained after cryopreservation. Somaclonal variation was observed in ETc and CSE of P. omorika and at ETv stage of P. abies. However, most of the changes were induced at the stage of somatic embryogenesis initiation. These results confirm the need for monitoring the genetic stability of plants obtained by somatic embryogenesis and after cryopreservation for both spruce species.

Opis:: Somatic embryogenesis was studied in four spruce species (Picea abies, P. omorika, P. pungens 'Glauca' and P. brewenana) to determine if this method can be used for in vitro propagation of coniferous trees. The highest frequency of initiation of embryogenic tissue was obtained when mature zygotic embryos were used as explants. It ranged then from 10.8% (P. brewenana) to 23.75% (P. omorika and P. pungens 'Glauca'). The frequency of embryogenic tissue initiation was strongly affected by medium composition, i.e. addition of appropriate auxins (2,4-D, NAA, Picloram) and sucrose concentration (10-20 g-1"1). A lower frequency was obtained in Picea omorika (10%) when megagametophytes (endosperms with immature zygotic embryos) were used as explants. No emryogenic tissue was produced from hypocotyls, cotyledons and needles. A satisfactory frequency was achieved with the use of somatic embryos of Picea abies (30%). The proliferation of embryogenic cell lines of spruces was affected by medium type. The experiments resulted in production of somatic plantlets of P. abies and P. omorika. This enables the application of this method of spruce micropropagation for genetic and breeding research or for nursery production.

Opis:: The text is a synthetic description of Edward Pasewicz’s poetic work, which is included within the “plan for a somatic criticism.” The key operational concept used to describe this poetry is rhythm, which spreads out on all the levels of expression like a theme in a story and makes the texts of every poet unique and original. The rhythm is closely linked with the process of listening and with the body itself, which generates it. Following Charlers Berstein, the author performs an act of Close Listening, attempting to point out the relations between rhythm, the sphere of sound in Pasewicz’s poetic texts, and a speaking subject.
