Predicting the chromosomal location of mapped markers has been difficult because linkage maps do not reveal differences in crossover frequencies along the physical structure of chromosomes. Here we combine a physical crossover map based on the distribution of recombination nodules (RNs) on Solanum lycopersicum (tomato) synaptonemal complex 1 with a molecular genetic linkage map from the intersp...

Total ascorbic acid (total-AsA) content and percentage of reduced ascorbic acid (AsA) on total-AsA were investigated and discussed in fruits, leaves, petiole, stem and roots of the Solanum lycopersicum cv M82 and S. pennellii introgression lines IL7-3, IL10-1 and IL12-4. In fruits, total-AsA content showed to be different according to genotype analysed. Higher total-AsA accumulations were obser...

Clavibacter michiganensis subsp. (Cmm), is a devastating bacterial disease agent causing wilt and canker in tomatoes. There no definitive solution to prevent yield losses by Cmm Moreover, there currently commercially successful resistant tomato cultivar on the market. Therefore, we aimed determine tolerance level of some accessions present study. For this purpose, screened seven representing fo...

Cytological information is absolutely lacking for the Iranian moss flora (Bryophytes). The present research, dealing with cytological studies on the following five species (including two expressions and one variety) of Iranian mosses, namely, Amblystegium riparium (Hedw.) B.S.G. “brevipes” expression(n=20), A. riparium (Hedw.) B.S.G. “pennellii” expression (n=9, 9+m, 9+2m), A. serpens (Hedw.) B...

ABSTRACT The selection of genotypes with agronomic potential associated drought tolerance is considered high complexity. An alternative could be the use indexes that can evaluate multiple characteristics simultaneously. This study aimed to select tomato and by indexes. experiment was conducted in a randomized block design three replications. Ten treatments were evaluated: seven F2RC3, donor gen...

The complete mRNA sequence of one tobacco (nicotiana tabacum) gene—guanosine monophosphate (GMP)synthase, was amplified using the rapid amplification cDNA ends methods. full-length GMP synthase gene 2,127bp containing a 1,617 bp open reading frame, which encodes protein 538 amino acids. Sequence analysis revealed that shares high homology with wood tobacco(99%), nicotiana attenuata(99%), toment...
