An analysis of interspecific hybrids and phylogenetic implications inCucumis (Cucurbitaceae)

Interspecific Hybrids

The regulation of gene expression is essential for organismal form, function, and fitness. Complex organismal development from zygote to adult requires finely tuned expression of genes in space, time, and abundance. Proper expression of genes is also required for most other aspects of physiology and function. Even minor changes in gene expression have the potential to significantly impact pheno...

An introduction to mammalian interspecific hybrids.

Haldane's law states that in interspecific hybrids, it is the heterogametic sex that is likely to be absent, rare, or sterile. In mammals, there is increasing evidence to suggest that this may be due to the high mutation rate of male sex-determining genes on the Y chromosome. The mule, humanity's first successful attempt at genetic engineering, provides some support for this concept. Interspeci...

Meiotic behavior of interspecific hybrids

The meiotic behavior of four interspecific promising hybrids was evaluated by conventional cytological methods. The female genitors were two artificially tetraploidized sexual accessions of B. ruziziensis (R41 and R44, 2n = 4 χ = 36), which were crossed to an agronomically superior natural tetraploid apomictic genotype of B. brizantha (B140 BRA003395). Three of them (HBGC313, HBGC 315, and HBGC...

Transcriptome analysis of response to drought in poplar interspecific hybrids

To investigate the response of poplar hybrids to drought, leaves were collected from plants to which water was suspended for 8 and 13 days. After measuring the respective relative water content, RNAs were isolated from leaves of moderately and severely droughted plants and from control plants, and Illumina RNA sequencing was performed to analyze RNA synthesis in these tissues. Our data provide ...
