The Study of Morphological Traits and Identification of Self-incompatibility Alleles in Almond Cultivars and Genotypes
The evaluation of an almond collection using morphological variables and identification of self-incompatibility genotype is useful for selecting pollinizers and for the design of crossing in almond breeding programs. In this study, important morphological traits and self-incompatibilities in 71 almond cultivars and genotypes were studied. Simple and multiplex specific PCR analyses were used in...
متن کاملIdentification of stylar RNases associated with gametophytic self-incompatibility in almond (Prunus dulcis).
Stylar proteins of 13 almond (Prunus dulcis) cultivars with known S-genotypes were surveyed by IEF and 2D-PAGE combined with immunoblot and N-terminal amino acid sequence analyses to identify S-RNases associated with gametophytic self-incompatibility (SI) in this plant species. RNase activities corresponding to Sa and Sb, two of the four S-alleles tested, were identified by IEF and RNase activi...
متن کاملIdentification of Self- incompatibility Alleles in Some Almond Genotypes by Degenerate S-RNase Primers
The almond, Prunus dulcis Miller which belongs to Rosaceae family, is one of the most important commercial and oldest cultivated tree nut crops. Almonds are classified as a ‘nut’ in which the edible seed is the commercial product. Therefore, pollination and fertilization are necessary in almond. The characteristic of cultivated almond to express gametophytic self- incompatibility discourages se...
متن کاملAnatomy and cell wall polysaccharides of almond (Prunus dulcis D. A. Webb) seeds.
The anatomy of Prunus dulcis was analyzed by applying several differential staining techniques and light microscopy. Prunus dulcis seed has a thin and structurally complex seed coat, with lignified cellulosic tissue. The embryo has two voluminous cotyledons. Cotyledon cells have a high number of protein and lipid bodies, some of which have phytin. The provascular tissue, located in the cotyledo...
متن کاملCloning and characterization of profilin (Pru du 4), a cross-reactive almond (Prunus dulcis) allergen.
BACKGROUND The identity of allergenic almond proteins is incomplete. OBJECTIVE Our objective was to characterize patient IgE reactivity to a recombinant and corresponding native almond allergen. METHODS An almond cDNA library was screened with sera from patients with allergy for IgE binding proteins. Two reactive clones were sequenced, and 1 was expressed. The expressed recombinant allergen...
