Development and use of a gene deletion strategy for Flavobacterium johnsoniae to identify the redundant gliding motility genes remF, remG, remH, and remI.
Cells of Flavobacterium johnsoniae exhibit rapid gliding motility over surfaces. Cell movement is thought to involve motor complexes comprised of Gld proteins that propel the cell surface adhesin SprB. The four distal genes of the sprB operon (sprC, sprD, sprB, and sprF) are required for normal motility and for formation of spreading colonies, but the roles of the remaining three genes (remF, r...
متن کاملCloning and characterization of the Flavobacterium johnsoniae gliding-motility genes gldB and gldC.
The mechanism of bacterial gliding motility (active movement over surfaces without the aid of flagella) is not known. A large number of mutants of the gliding bacterium Flavobacterium johnsoniae (Cytophaga johnsonae) with defects in gliding motility have been previously isolated, and genetic techniques to analyze these mutants have recently been developed. We complemented a nongliding mutant of...

The mechanism of bacterial gliding motility (active movement over surfaces without the aid of flagella) is not known. A large number of nonmotile mutants of the gliding bacterium Flavobacterium johnsoniae (Cytophaga johnsonae) have been previously isolated, and genetic techniques to analyze these mutants have recently been developed. We complemented a nonmotile mutant of F. johnsoniae (UW102-09...
متن کاملFlavobacterium johnsoniae GldH is a lipoprotein that is required for gliding motility and chitin utilization.
Cells of Flavobacterium johnsoniae move rapidly over surfaces by gliding motility. The mechanism of this form of motility is not known. Six genes (gldA, gldB, gldD, gldF, gldG, and ftsX) that are required for gliding have been described. Tn4351 mutagenesis was used to identify another gene, gldH, which is required for cell movement. GldH mutants formed nonspreading colonies, and individual cell...

آب حاصل از بارش منبع تأمین نیازهای بی شمار جانداران به ویژه انسان است و هرگونه کاهش در کم و کیف آن مستقیماً حیات موجودات زنده را تحت تأثیر منفی قرار می دهد. نوسان سال به سال بارش از ویژگی های اساسی و بسیار مهم بارش های سالانه ایران محسوب می شود که آثار زیان بار آن در تمام عرصه های اقتصادی، اجتماعی و حتی سیاسی- امنیتی به نحوی منعکس می شود. چون میزان آب ناشی از بارش یکی از مولفه های اصلی برنامه ...
