Copy number variation in transcriptionally active regions of sexual and apomictic Boechera demonstrates independently derived apomictic lineages.
In asexual (apomictic) plants, the absence of meiosis and sex is expected to lead to mutation accumulation. To compare mutation accumulation in the transcribed genomic regions of sexual and apomictic plants, we performed a double-validated analysis of copy number variation (CNV) on 10 biological replicates each of diploid sexual and diploid apomictic Boechera, using a high-density (>700 K) cust...
متن کاملIn Vitro Characterization of Apomictic Reproduction in Guayule
Guayule (Parthenium argentatum Gray, Asteraceae) is a latex-producing perennial desert shrub native to southwestern Texas and north central Mexico. It is potentially an economically viable new crop for the desert Southwest, with the advantages of having low water requirements and producing non-allergenic latex (Thompson and Ray 1988). Diploid guayule plants reproduce predominantly sexually, and...
متن کاملMaternal Recto-Vaginal Organisms and Surface Skin Colonization in Infants
Background: Early-onset sepsis is a common cause of neonatal mortality and mainly occurs due to the colonized microorganisms in the maternal recto-vaginal area. The present study aimed to evaluate the effects of maternal risk factors on recto-vaginal colonization and transmission rate of micro-flora from mothers to infants. Methods: Upon admission, two samples were obtained from the distal thi...
متن کاملclonality V.0.4: a randomization-based program to test for heterozygosity-genet size relationships in clonal organisms.
clonality V.0.4 is a program for testing heterozygosity-genet size relationships in clonal organisms using a randomization procedure. The software has been developed under the Borland Delphi developing environment and a Windows-executable version is freely downloadable from http://gemi.mpl.ird.fr/SiteSGASS/Prugnolle/ClonalityPage.html. The program compares the observed F(IS) of the population w...
متن کاملSmall RNAs Reflect Grandparental Environments in Apomictic Dandelion
Plants can show long-term effects of environmental stresses and in some cases a stress "memory" has been reported to persist across generations, potentially mediated by epigenetic mechanisms. However, few documented cases exist of transgenerational effects that persist for multiple generations and it remains unclear if or how epigenetic mechanisms are involved. Here, we show that the compositio...
