Isolated severe thunderstorms with a potential for large hail and wind damage are possible today across parts of the southern Plains into the northern Ozarks. Marginally severe thunderstorms with strong wind gusts and hail are also possible from the Ohio Valley into the central and northern Appalachians. Chehalis-Centralia Airport (KCLS)
A pilus (Latin for 'hair'; plural: pili) is a hairlike appendage found on the surface of many bacteria. The terms pilus and fimbria (Latin for 'fringe'; plural: fimbriae) can be used interchangeably, although some researchers reserve the term pilus for the appendage required for bacterial conjugation.ovement produced by type IV pili is typically jerky, and so it is called twitching motility, as distinct from other forms of bacterial motility, such as motility produced by flagella. However, some bacteria, for example Myxococcus xanthus, exhibit gliding motility.
Pili and fimbriae are known as filamentous appendages, which are used mainly for adhesion. These structures are extremely fine appendages arising from the surface of bacteria and are firstly described by hoodwink and van Iterson. These are thinner than flagella and are not used in motility.nlike the flagella, pili are not used in motility. Special type of pili called âsex piliâ is required in the process of bacterial conjugation. A pilus makes a cytoplasmic concoction called âconjugation tubeâ with the host cell. This tube is then used to transfer genetic materials from the donor cell to recipient cell.
