Salt stress causes a shift in the localization pattern of germin gene expression
Authors: M. Caliskan
The response of plants to biotic and abiotic stress factors involves biochemical, physiological, morphological, and developmental changes. Salt stress has been the subject of extensive studies due to the low salt tolerance of many crop plants. Germin and germin-like gene products are known to be involved in various aspects of ..

Africanized honey bees more efficiently convert protein diets into hemolymph protein than do Carniolan bees (Apis mellifera carnica)
Authors: F.A. Cappelari, A.P. Turcatto, M.M. Morais and D. De Jong
The superiority of Africanized over European honey bees in tropical and subtropical regions of the New World is both well documented and poorly understood. As part of an effort to try to understand the process by which the displacement of European bees occurred, we examined the ability of these two types of bees and of hybrids.. Read More»

An assessment of genetic variability and relationships among wild-grown blackthorn (Prunus spinosa L.) plants based on RAPD markers
Authors: Y. Erturk, S. Ercisli, D. Maghradze, E. Orhan and G. Agar
Prunus spinosa, blackthorn, exists as wild populations that inhabit uncultivated uplands of Coruh Valley in the northeastern part of Turkey; the fruit is used to make preserves. We examined genetic diversity in wild-grown Prunus spinosa; 16 individual plants from wild populations of Coruh Valley were sampled and subjected to R.. Read More»

Buccal micronucleus frequency is associated with age in Down syndrome
Authors: F.L.S. Ferreira, D. PrĂ?¡, M.G. Martino-Roth and G.L. Garcias
Down syndrome has been linked to premature aging and genomic instability. We examined the frequency of micronucleus (MN) and binucleated cells in the oral mucosa of Down syndrome patients and healthy controls matched by age and gender, addressing the effect of age and family income. Down syndrome individuals had an increased n.. Read More»

FISH analysis and cytogenetic characterization of male meiotic prophase I in Acricotopus lucidus (Diptera, Chironomidae)
Authors: W. Staiber
In the chironomid Acricotopus lucidus, two cells with quite different chromosome complements arise from the last unequal spermatogonial mitosis, as a consequence of monopolar migration of the so-called germ line limited chromosomes (Ks). The cell receiving all the Ks, in addition to two sets of the regularly segregating somati.. Read More»

Cytogenetic findings in an epithelioid sarcoma with angiomatoid features. A case report
Authors: M.S. Brassesco, E.T. Valera, A.M. Castro-Gamero, D.A. Moreno,T.P. Silveira, B.M. Mori, E.E. Engel4, C.A. Scrideli and L.G. Tone
Epithelioid sarcoma is a rare, aggressive soft tissue tumor of unknown histogenesis showing predominantly epithelioid cytomorphology. We conducted a conventional and molecular cytogenetic study of a 27-year-old male with epithelioid sarcoma with angiomatoid features. Cytogenetic analysis of epithelioid sarcoma metaphase spread..

Variation of genomic DNA methylation in the nitrate reductase gene of sibling tobacco (Nicotiana tabacum) cultivars
Authors: S.L. Fu, Z.X. Tang, L. Liu, L.M. Lu and Y.B. Huang
To better understand genomic DNA methylation in sibling plant cultivars, methylation-sensitive amplification polymorphism analysis was used to investigate two sibling tobacco cultivars, Yunyan85 and Yunyan87, and their two parents, K326 and Yunyan No. 2. Differences in the degree of genomic DNA methylation were found among the.. Read More»

Molecular cloning and single nucleotide polymorphism analysis of IGF2a genes in the common carp (Cyprinus carpio)
Authors: S.Y. Su, Z.J. Dong, J.Q. Qu, Z.Y. Liang, J.Q. Zhang, L.X. Ma, W. Liu, P. Xu and X.H. Yuan
We studied whether two IGF2 transcripts in common carp are similar to those found in zebrafish. The full-length IGF2a cDNA contains a 5'-terminal untranslated region (UTR) of 105 bp, a 3'-terminal UTR of 1358 bp and an open reading frame of 612 bp, which encodes a 206-amino acid protein. A 6614-bp full-length IGF2a DNA molecul.. Read More»

Characterization of microsatellite markers in cassava based on microsatellite-AFLP technique
Authors: S. Whankaew, S. Sraphet, R. Thaikert, D.R. Smith and K. Triwitayakorn
We developed molecular markers for cassava based on the microsatellite-amplified fragment length polymorphism (M-AFLP) technique. Twenty primer pairs were developed and used for the analysis of 48 samples of Manihot species, consisting of M. esculenta (33), M. esculenta ssp flabellifolia (3), M. chlorosticta (3), M. carthagine..

Microsporogenesis in Brachiaria brizantha (Poaceae) as a selection tool for breeding
Authors: M.S. Pagliarini, C.B. Valle, E.M. Santos, D.V. Mendes, Z.H. Bernardo, A.B. Mendes-Bonato, N. Silva and V. Calisto
The genus Brachiaria comprises more than 100 species and is the single most important genus of forage grass in the tropics. Brachiaria brizantha, widely used in Brazilian pastures for beef and dairy production, is native to tropical Africa. As a subsidy to the breeding program underway in Brazil, cytological studies were emplo.. Read More»
