Autologous bone powder; Bone histomorphometry; Graft; Mandibular defect

The aim of this study was to understand the effect of autologous bone powder graft repair of partial mandibular defects of rabbits by the quantitative detection of bone formation. New Zealand rabbits (N = 18) were selected as the test objects, and subjected to bilateral partial mandibular defect induction. One side of the mandibular defect acted as the test group, upon which the ... more

Brachiaria; Chaco grass; Microsporogenesis; Native grass; Polyploidy

This is the first report of meiotic division in Uro­chloa adspersa (Trin.) collected from the Brazilian Chaco. Meiotic analyses were performed on three specimens of U. adspersa named G10, G15, and G16. Inflorescences were collected and fixed in a mixture of ethanol and acetic acid (3:1, v/v) for 24 h and then stored in 70% alcohol. Diakinesis revealed different ... more

Microsatellite DNA marker; Pollen; Polyploidy; Saccharum spp. hybrids; Self-progeny

No information is available on segregation analysis of DNA markers involving both pollen and self-progeny. Therefore, we used capillary electrophoresis- and fluorescence-based DNA fingerprinting together with single pollen collection and polymerase chain reaction (PCR) to investigate simple sequence repeat (SSR) marker segregation among 964 single pollens and 288 self-progenies (S1) of ... more

Polyploid induction has been used for plant breeding to produce bigger and more robust plants than diploid types. The present study aimed to develop a methodology for in vitro induction of polyploidy in cassava. Apical and lateral microcuttings from the BRS Formosa variety were treated with six oryzalin concentrations for 24 and 48 h. The same methodology was used for colchicine ... more

Chromosomes; Cytogeography; Karyotype; Myrtaceae; Neotropics; Polyploidy

Polyploidy is one of the most important mechanisms of speciation and diversification in plant evolution. Polyploidy results in genetic variation among individuals of the same species and even between populations, and may be responsible for differences in environmental tolerance between populations of the same species. This study determined chromosome numbers of ... more

Cryopreservation has been proven significance as a technique for promising the long-term conservation of plant germplasms. This study aimed to establish a cryopreservation protocol for calli of Schisandra chinensis (Turcz.) Baill, and to explore the effects of different process parameters on callus viability. Effects of desiccation duration, cryoprotectants and cryopreservation methods, ... more

The strawberry (Fragaria x ananassa Dutch.), is the only vegetable belonging to the rosacea family. All strawberry species have now emerged from wild species and belong to the genus Fragaria, being that this genus presents more than 45 described species, and only 11 are considered natural species. Due to the octoploid nature of strawberry and its variability after hybridization, selecting one ... more

We used the conventional and methylation-sensitive randomly amplified polymorphic DNA (RAPD) and inter-simple sequence repeat (ISSR) analyses to assess genome-wide changes and explore the relationships between genetic and epigenetic variations among individuals of a newly synthesized allohexaploid wheat line whose genomic constitution is identical to that of the natural common wheat, compared ... more

AFLP; Argopecten; Heterosis; Hybrid; SSR

Argopecten purpuratus and Argopecten irradians irradi­ans hybridization was successfully performed and the hybrid offspring displayed apparent heterosis in growth traits. To better understand the genetic basis of heterosis, the genomic composition and genetic varia­tion of the hybrids were analyzed with amplified fragment length poly­morphism (AFLP) and simple sequence repeat (SSR) ... more

Differentially expressed gene; Grain filling stage; Heterosis; Hybrid millet

Heterosis has been widely used in crop breeding and production. However, a shortage of genes known to function in heterosis significantly limits our understanding of the molecular basis underlying heterosis. Here, we report 740 differentially expressed genes (DEGs) in the leaves of the hybrid millet Zhang No.5 and its parents at the grain filling stage determined using Solexa Illumina ... more
