The sequence of events leading to the programmed cell death (PCD) induced by heavy metals in plants is still the object of extensive investigation. In this study we showed that roots of 3-day old yellow lupine (Lupinus luteus L.) seedlings exposed to cadmium (Cd, 89μM CdCl(2)) resulted in PCD starting from 24h of stress duration, which was evidenced by(More)
The primed mobilization for more potent defense responses to subsequent stress has been shown for many plant species, but there is a growing need to identify reliable molecular markers for this unique phenomenon. In the present study a proteomic approach was used to screen similarities in protein abundance in leaves of primed potato (Solanum tuberosum L.)(More)
Division of labor and caste specialization plays an important role in many aspects of social insect colony organization, including parasite defense. Within leaf-cutting ant colonies, worker caste specialization permeates colony tasks ranging from foraging, substrate incorporation, brood care, and chemical defenses via glandular secretions and mutualistic(More)
The phenomenon of cross-resistance allows plants to acquire resistance to a broad range of stresses after previous exposure to one specific factor. Although this stress–response relationship has been known for decades, the sequence of events that underpin cross-resistance remains unknown. Our experiments revealed that susceptible potato (Solanum tuberosum(More)
Fourteen new polymorphic di- and di-tetra complex microsatellite loci were isolated and characterized from the edible dormouse (Glis glis). The markers were tested on 427 individuals representing populations from Croatia and Poland. All loci were polymorphic, with the number of alleles per locus ranged from 4 to 31, with a mean of 10. Observed and expected(More)
We investigated how potato exposed to a chemical agent could activate nitric oxide (NO)-dependent events facilitating more potent defense responses to a subsequent pathogen attack. Obtained data revealed that all applied inducers, i.e., β-aminobutyric acid (BABA), γ-aminobutyric acid (GABA), laminarin, or 2,6-dichloroisonicotinic acid (INA), were active(More)
The transcript of the PR1 gene accumulation as an informative marker of systemic acquired resistance (SAR) was analyzed in β-aminobutyric acid (BABA) primed potato in the short-lasting (3 days) and long-lasting (28 days) time periods after induction and in the vegetative descendants of primed plants derived from tubers and from in vitro seedlings. BABA(More)
In our experimental approach we investigated how post-infection nitric oxide-dependent signaling activated in potato leaves was related to defense against avirulent (avr) and virulent (vr) races of Phytophthora infestans. Results revealed that only in an incompatible response, early NO and superoxide (O2 •-) generation led to peroxynitrite (ONOO−) formation(More)
In our experimental approach we examined how potato leaves exposed to a chemical agent might induce nitric oxide (NO) dependent biochemical modifications for future mobilization of an effective resistance to Phytophthora infestans. After potato leaf treatment with one of the following SAR inducers, i.e. β-aminobutyric acid (BABA), 2,6-dichloroisonicotinic(More)
