Progress towards sugar beet improvement through somatic hybridization I. Inactivation of nuclei and cytoplasm in donor and recipient protoplasts

open access: yesActa Societatis Botanicorum Poloniae, 2014
The isolation and culture of suspension-derived protoplasts from two sugar beet (Beta vulgaris L.) genotypes are described. Immobilization of protoplasts in agarose resulted in high frequency divisions and microcallus regeneration, with plating ...

Polystyrene nanoparticles induce concerted response of plant defense mechanisms in plant cells

open access: yesScientific Reports, 2023
Recent advances in knowledge suggest that micro- and nanoplastics pose a threat to plant health, however, the responses of plants to this stressor are not well-known.

Optimized In Vitro Restriction Digestion Protocol for Preparing Maize and Barley ddRAD-Seq Libraries

open access: yesAgronomy, 2023
In recent years, high-throughput sequencing methods have become increasingly popular in molecular biology laboratories, mainly due to the relatively low cost of small, benchtop platforms, the simplicity of library preparation, and the low price per unit ...

Formation of the phenotypic structure of Phytophthora infestans population in Poland during 1987-2001

open access: yesActa Agrobotanica, 2013
The formation of phenotypic structure of P.infestans population in Poland was determined by analyzing 1603 isolates collected from 1987 to 2001. The race complexity, low at the beginning of experiment, has been increasing from year to year and reached ...

Monitoring of Natural Occurrence and Severity of Leaf and Glume Blotch Diseases of Winter Wheat and Winter Triticale Incited by Necrotrophic Fungi Parastagonospora spp. and Zymoseptoria tritici

open access: yesAgronomy, 2021
The occurrence of necrotrophic winter wheat and triticale pathogens in eight geographical regions of Poland was studied between 2015 and 2020. Over a period of six years, the incidence of the following pathogens was monitored: Parastagonospora nodorum ...

Snow mould prevalence on perennial ryegrass (Lolim perenne L.) in relation to the light conditions and intensity of turf maintenance

open access: yesActa Agrobotanica, 2012
Effect of shade, nutrition, height of mowing and density of turf on snow mould (Microdochium nivale) prevalence on Lolium perenne under turf maintenance were studied in 2000-2004 at Radzików (central Poland). The materials for studies were cultivars of L.

Measuring Fluorescence as a Means to Evaluate the Physiological Reaction to Growth Retardant Applied to Manage Turf

open access: yesAgronomy, 2022
This paper presents the effects of the physiological reaction of the main cool-season grass species used for turf in a temperate climate: perennial ryegrass, Kentucky bluegrass, and tall fescue, on a twice-a-year trinexapac-ethyl (TE) application in late

Thidiazuron-induced shoot organogenesis from mature leaf explants of scented Pelargonium capitatum cultivars [PDF]

open access: yes, 2011
Shoot organogenesis from mature leaf tissues of two scented Pelargonium capitatum cultivars, ‘Attar of Roses’ and ‘Atomic Snowflake’, grown in the greenhouse, were optimized in the presence of thidiazuron (TDZ).

The effect of combined glutamate receptor blockade in the NTS on the hypoxic ventilatory response in awake rats differs from the effect of individual glutamate receptor blockade. [PDF]

open access: yes, 2014
Ventilatory acclimatization to hypoxia (VAH) increases the hypoxic ventilatory response (HVR) and causes persistent hyperventilation when normoxia is restored, which is consistent with the occurrence of synaptic plasticity in acclimatized animals ...
