Cryopreservation of embryogenic tissues of Picea omorika (Serbian spruce)

Plant Cell, Tissue and Organ Culture (PCTOC), 2010
Two-year-old embryogenic tissues (ET) of Picea omorika (Pancic) Purk. were successfully cryopreserved after preculture with sucrose, air-drying for 2 h, and freezing in liquid nitrogen (LN). The preculture protocol consisted of passaging the ET onto standard Litvay medium containing increasing concentrations of sucrose (0.25 M sucrose for 24 h, 0.5 M ...

Fluorescent chromosomal banding in Picea omorika and P. abies

1997
Cytological investigation were conducted on Picea omorika, an endemic species to the Balkan region. The chromosome number was confirmed to be 2n=2x=24, and the chromosomes were metacentric, except two pairs with submetacentric centromeres. The chromosomes were differentially stained by chromomycin A3 (CMA) and Hoechst 33258.

Somatic Embryogenesis and Plant Regeneration in Picea Omorika

1995
The genus Picea comprises more than 40 species, most of which are confined to the northern hemisphere in Europe, Asia and North America. Serbian spruce, Picea omorika (Pancic) Purk. is a Tertiary, relic species endemic to the Balkan Peninsula. It is believed to have originated from Tertiary ancestors, once widely distributed over Central Europe.

DNA Methylation During Somatic Embryogenesis of Picea omorika

2003
The DNA methylation of Picea omorika line BB19, in correlation with embryogenic potential and embryo maturation, was investigated. Cytosine methylation level was detected using random amplification coupled with restriction enzyme digestion. The long– term embryogenic cultures were maintained on the induction medium (IM): basic LP supplemented ...

Refugial habitats of paleoendemic Picea omorika: soil and plant attributes

Science of The Total Environment
Refugial habitats occupied by palaeoendemic species provide valuable insights into the adaptive strategies of populations shaped by long-term climatic and environmental change. They also help to assess the conservation potential of refugia under future climate scenarios.

Istraživanje građe vegetativnih pupova vrsta Picea pungens i Picea omorika

1992
Cilj ovog rada je prikazati morfološku i anatomsku građu vegetativnih pupova vrsta Picea pungens i Picea omorika te dobivene rezultate usporediti s onima koji su poznati. Promatranja i mjerenja učinjena su na longitudinalnim presjecima debljine 3 μ m genetički uniformnih vegetativnih pupova vrsta Picea pungens i Picea omorika sakupljenih u mjesecu ...

Cytogenetic comparison of Picea abies (L.) Karsten and Picea omorika (Pančić) Purk.

1997
A wild distributed species Picea abies and a paleoendemic (a tertiary relict) narrow localized Picea omorika have been cytogenetically investigated. Both of them showed identical chromosome number 2n=24, and morphologically similar karyotypes. We used some molecular cytogenetic techniques to find out whether any interspecific difference at chromosomal ...

Standardization of gymnosperm karyotypes using Picea omorika as an example

Forest genetics, 1996
The karyotype analysis of a single Picea omorika (Panč.) Purk. tree was completed using female gametophyte tissue. Most chromosomes (n=12) were metacentric, but chromosomes IX and XII were submetacentric. The positions of the centromeres of chromosomes X and XI wereclose to submetacentric, but were classified as metacentric.

Dc3 promoter activity in tranformed somatic embryos of omorika spruce (Picea omorika (Panč.) Purk.)

1999
Somatski embriji jako embriogene linije BB19 zaraženi su bakterijama A. tumefaciens soj LBA 4404 s binarnim vektorom pBI121 ili pBI101Dc3. Privremena ekspresija gena gusA histokemijski je kvantificirana. Učinkovitost privremene transformacije izražena je kao postotak GUS-pozitivnih somatskih embrija (50%) i kao postotak GUS-aktivne površine somatskih ...
