Identification of high-efficiency SSR markers for assessing watermelon genetic purity.

Genomic simple sequence repeat (SSR) markers were used to fingerprint and determine genetic similarity (GS) of the watermelon breeding lines, as well as the purity of their hybrid derivatives. Cluster analysis and Jaccard's distance coefficients using the unweighted pair group method with arithmetic mean (UPGMA) have classified these lines into three major groups. Notwithstanding,the genetic background of these lines is narrow as revealed by the restricted GS coefficients.

Development of a New Molecular Marker for the Resistance to Tomato Yellow Leaf Curl Virus.

(TYLCV) responsible for tomato yellow leaf curl disease (TYLCD) causes a substantial decrease in tomato ( L.) yield worldwide. The use of resistant variety as a sustainable management strategy has been advocated.

Protein-protein interactions between proteins of Citrus tristeza virus isolates.

Citrus tristeza virus (CTV) is one of the most devastating pathogens of citrus. Its genome is organized into 12 open reading frames (ORFs), of which ten ORFs located at the 3'-terminus of the genome have multiple biological functions. The ten genes at the 3'-terminus of the genome of a severe isolate (CTV-S4) and three ORFs (CP, CPm and p20) of three other isolates (N4, S45 and HB1) were cloned into pGBKT7 and pGADT7 yeast shuttle vectors.
