Effect of the Strawberry Genotype, Cultivation and Processing on the Fra a 1 Allergen Content [PDF]

open access: yes, 2018
Birch pollen allergic patients show cross-reactivity to vegetables and fruits, including strawberries (Fragaria × ananassa). The objective of this study was to quantify the level of the Fra a 1 protein, a Bet v 1-homologous protein in strawberry fruits

Gametes with somatic chromosome number and their significance in interspecific hybridization in Fuchsia

open access: yesBiologia Plantarum, 2011
Sexual polyploidization has both a theoretical as well as an applied significance. Morphological screening for large pollen grains and shape of pollen produced by the individual, cytological investigation of hybrid progeny, and unbalanced separation of ...

Cold-induced male meiotic restitution in Arabidopsis thaliana is not mediated by GA-DELLA signaling [PDF]

open access: yes, 2018
Short periods of cold stress induce male meiotic restitution and diploid pollen formation in Arabidopsis thaliana by specifically interfering with male meiotic cytokinesis.

Meiotic Studies in Some Species of Tribe Cichorieae (Asteraceae) from Western Himalayas

open access: yesThe Scientific World Journal, 2014
The present paper deals with meiotic studies in 15 species belonging to 6 genera of the tribe Cichorieae from various localities of Western Himalayas. The chromosome number has been reported for the first time in Hieracium crocatum (2n=10) and Lactuca ...

Structure of anther heads in some Trifolium L. species

open access: yesActa Societatis Botanicorum Poloniae, 2015
The species of the genus Trifolium differ by the number of pollen sacs in stamen heads. Some have only two, other four and in some species there arę two, three or four pollen sacs.

Chromosomal and morphological studies of diploid and polyploid cytotypes of Stevia rebaudiana (Bertoni) Bertoni (Eupatorieae, Asteraceae)

open access: yesGenetics and Molecular Biology, 2004
In this study, we examined the chromosome number and some morphological features of strains of Stevia rebaudiana. The chromosomes were analyzed during mitosis and diakinesis, and the tetrad normality and pollen viability were also assessed.

Relevance of unilateral and bilateral sexual polyploidization in relation to intergenomic recombination and introgression in Lilium species hybrids [PDF]

open access: yes
Sexual polyploids were induced in diploid (2n = 2x = 24) interspecific F1 hybrids of Longiflorum × Asiatic (LA) and Oriental × Asiatic (OA) Lilium hybrids by backcrossing to Asiatic (AA) parents as well as by sib-mating of the F1 LA hybrids.

Genome composition of 'Elatior'-begonias hybrids analyzed by genomic in situ hybridisation [PDF]

open access: yes, 2010
Interspecific hybridization of various tuberous Begonia species hybrids with Begonia socotrana results in so-called 'Elatior'-begonias hybrids (B. x hiemalis Fotsch).

Interspecific somatic hybrids between Solanum bulbocastanum and S. tuberosum and their haploidization for potato breeding. [PDF]

open access: yes, 2012
Protoplast fusion between incongruent Solanum bulbocastanum and S. tuberosum haploids was accomplished to produce hybrids combining elite traits from both parents. We identified 11 somatic hybrids out of 42 regenerants analyzed through ISSR markers. Some

Genetic variability of anther donor versus spontaneous doubled haploid descendents and colchicine induced doubled haploid sweet pepper (Capsicum annuum L.) lines [PDF]

open access: yes, 2001
Haploid (n) and doubled haploid (DH) plants were developed in anther culture of sweet pepper (Capsicum annuum L.). Regenerants were analyzed by flow cytometry for haploid (n = 12) and spontaneous doubled haploid (2n = 24) genomes.
