Electroporation is a widely used method for the introduction of polar and charged agents such as dyes, drugs, DNA, RNA, proteins, peptides, and amino acids into cells. Traditionally, electroporation is performed with large electrodes in a batch mode for treatment of a large number of cells in suspension. Recently, microelectrodes that can produce extremely localized electric fields, such as solid carbon fiber microelectrodes, electrolyte-filled capillaries and micropipettes as well as chip-based microfabricated electrode arrays, have proven useful to electroporate single cells and subcellular structures. Single-cell electroporation opens up a new window of opportunities in manipulating the genetic, metabolic, and synthetic contents of single targeted cells in tissue slices, cell cultures, in microfluidic channels or at specific loci on a chip-based device. 相似文献

The N6-methyladenosine (m6A) modification of mRNA has a crucial function in regulating pluripotency in murine stem cells: it facilitates resolution of naïve pluripotency towards differentiation. 相似文献

Many conclusions about mammalian ranging behaviour have been drawn based on minimum convex polygon (MCP) estimates of home
range size, although several studies have revealed its unpredictable nature compared to that of the kernel density estimator.
We investigated to what extent the choice of home range estimator affected the biological interpretation in comparative studies.
We found no discrepancy when the question asked covered a wide range of taxa, as real and very large differences in range
size were likely to have masked smaller differences due to the choice of home range estimator. However, when the question
asked concerned within-species characteristics, the choice of home range estimator explained as much of the variation in range
size as did the ecological variable in question. The implications for macro-ecological and intraspecific studies are discussed. 相似文献

Species belonging to the Festuca-Lolium complex are important forage and turf species and as such, have been studied intensively. However, their out-crossing nature and limited availability of molecular markers make genetic studies difficult. Here, we report on saturation of F. pratensis and L. multiflorum genetic maps using Diversity Array Technology (DArT) markers and the DArTFest array.The 530 and 149 DArT markers were placed on genetic maps of L. multiflorum and F. pratensis, respectively, with overlap of 20 markers, which mapped in both species. The markers were sequenced and comparative sequence analysis was performed between L. multiflorum, rice and Brachypodium. The utility of the DArTFest array was then tested on a Festulolium population FuRs0357 in an integrated analysis using the DArT marker map positions to study associations between markers and freezing tolerance. Ninety six markers were significantly associated with freezing tolerance and five of these markers were genetically mapped to chromosomes 2, 4 and 7. Three genomic loci associated with freezing tolerance in the FuRs0357 population co-localized with chromosome segments and QTLs previously identified to be associated with freezing tolerance. The present work clearly confirms the potential of the DArTFest array in genetic studies of the Festuca-Lolium complex. The annotated DArTFest array resources could accelerate further studies and improvement of desired traits in Festuca-Lolium species. 相似文献
