- Abstract:
- ... Approximately 4000 mature seeds from 350 trees in nine populations (12-75 trees per population) of Siberian stone pine were investigated for multiple embryos (polyembryony). Haploid megagametophytes and embryos were genotyped for eight allozyme loci. Eighty-one seeds (2.11%) had more than 1 embryo. Of these, 71 seeds had 2 embryos (1.85%), 6 seeds had 3 embryos (0.16%), 3 seeds had 4 embryos (0.08 ...

- Abstract:
- ... Dehydrins are ubiquitous plant proteins, synthesized in late stages of plant embryo development and following any environmental stress involving dehydration. With the aim to study the evolution of such a stress-responsive gene within Helianthus and to test the possibility of using this gene for phylogenetic studies, fragments of the same dehydrin gene were isolated by PCR and sequenced in 16 wild ...

Fertilization was achieved in all ten genotypes and no significant difference in fertilization frequency between the tetraploid wheat genotypes was detected. A mean of 41.1% of pollinated ovaries contained an embryo. All these crosses were characterized by the elimination of the maize chromosomes, a ...

A small gene family encodes PGIP in the genome of common bean, as indicated by Southern-blot experiments performed at high-stringency conditions. Southern-blot analysis of DNA extracted from different cultivars of Phaseolus vulgaris and from Phaseolus coccineus showed length polymorphis ...

The cultures were analyzed for ploidy level after 1-9 years. All lines tested were found to have doubled (2n=24) their chromosome number at the end of the experiment, though there were a few lines that still gave occasional haplo ...

Pollinations with maize were used in an attempt to produce haploid seedlings and, from these, fertile doubled haploids of durum wheats. Moreover, the effect of various concentrations and combinations of a synthetic auxi ...

Altogether, 33 different hybrid combinations were realized using the cultivated form, both as a female and male parent. The hybrids obtained have been identified by different methods, i.e., by comparison of leaf morphology, pollen stainability, chromosome number ...
