Siti W Mohd-Zin et al.
The EphA4 receptor tyrosine kinase is involved in numerous cell-signalling activities during embryonic development. EphA4 has the ability to bind to both types of ephrin ligands, the ephrinAs and ephrinBs. The C57BL/6J-Epha4rb-2J/GrsrJ stra...
Mutations in ash1 and trx enhance P-element-dependent silencing in Drosophila melanogaster [0.03%]
果蝇ash1和trx的突变增强P元素依赖性的基因沉默现象

In Drosophila melanogaster, the mini-w(+) transgene in Pci is normally expressed throughout the adult eye; however, when other P or KP elements are present, a variegated-eye phenotype results, indicating random w(+) silencing during develop...
The effects of parameter choice on defining molecular operational taxonomic units and resulting ecological analyses of metabarcoding data [0.03%]
