BACKGROUND The routine generation of transgenic plants involves analysis of transgene integration into the host genome by means of Southern blotting. However, this technique cannot distinguish between uniformly transformed tissues and the presence of a mixture of transgenic and non-transgenic cells in the same tissue. On the other hand, the use of reporter genes often fails to accurately detect...

The 5'-terminal genomic sequence of Cherry virus A (CVA) has long been unknown. We determined the first complete genome sequence of an apricot isolate of CVA (7,434 nucleotides [nt]). The 5'-untranslated region was 107 nt in length, which was 53 nt longer than those of known CVA sequences.

Türkiye’de Akdeniz bölgesi kayısıcılığı, gerek iç tüketimde taze kayısı gereksinimini karşılayacak, gerekse dış satımda rekabete girebilecek potansiyele sahiptir. Daha önce yapılan seleksiyon ve adaptasyon çalışmalarıyla bölgeye uyabilen, erkenci kaliteli çeşitler saptanmıştır. Ancak bu tüketim için belirlenen özellikleri tam anlamı ile üzerlerinde taşımamaktadırlar. Bu nedenle hem tüketimi kar...

The eye color phenotype of white-apricot (wa), a mutant allele of the white locus caused by the insertion of the transposable element copia into a small intron, is suppressed by the extragenic suppressor suppressor-of-white-apricot (su(wa] and enhanced by the extragenic enhancers suppressor-of-forked su(f] and Enhancer-of-white-apricot (E(wa]. Derivatives of wa have been analyzed molecularly an...

The reproductive fitness of seven isolates of Pratylenchus vulnus from different geographical areas and hosts was assessed in monoxenic cultures (carrot), and greenhouse cultures (plum, sour orange, and quince). The genetic makeup of the different isolates was compared by Random Amplified Polymorphic DNA (RAPD-PCR). The apple (PvAP-S) and apricot (PvAT-F) isolates reproduced less in monoxenic c...

In R2, we consider an analytic family of fractional integrals , whose convolution kernel is obtained by taking some transverse derivatives of arclength measure on the parabola (t, t2) multiplied by |t|γ , and doing so in a homogeneous way. We determine the exact range of p, q for which the analytic family maps Lp to Lq . We also resolve a similar issue on the Heisenberg group.

In genomic selection (GS), genotype × environment interaction (G × E) can be modeled by a marker × environment interaction (M × E). The G × E may be modeled through a linear kernel or a nonlinear (Gaussian) kernel. In this study, we propose using two nonlinear Gaussian kernels: the reproducing kernel Hilbert space with kernel averaging (RKHS KA) and the Gaussian kernel with the bandwidth estima...

The collection of stone fruit crops (peach, apricot and nectarine) was analyzed in accordance with their belonging to certain ecological-geographical groups ecotypes. most valuable characteristics were determined, sources economically properties identified, included crossbreeding combinations for intraspecific interspecific hybridization. Methods radiation chemical mutagenesis used the selectio...
