Citrus canker, caused by the bacterium Xanthomonas citri (Xcc), is one of most devastating diseases for citrus industry. Xylose a constituent cell wall plants, and ability Xcc to use this carbohydrate may play role in virulence. has two genes codifying xylose isomerase (XI), bifunctional enzyme that interconverts D-xylose into D-xylulose D-glucose D-fructose. The aim work was investigate functi...
مقدمه: زانتان هتروپلیساکاریدی است که توسط گروهی از باکتریهای بیماریزای گیاهی از جنس زانتوموناس [i] تولید میشود. به طور معمول برای تهیه زانتان از منابع کربنی مثل گلوکز، سوکروز و نشاسته استفاده میشود. به علت هزینههای بالای فراوری و حمل این منابع کربنی، هزینه نهایی تولید زانتان از منابع اشاره شده بالا میرود. به دلیل میزان بیان پایین و در برخی موارد نقص آنزیم بتا گالاکتوزیداز در بسیاری گو...
India is one of the leading citrus−producing countries, next to China and Brazil. Despite sizeable production, especially lemons limes, contributes meagerly world’s citrus market. Of various factors responsible for restricted quantum export, canker (Xanthomonas citri pv. citri) serious causes directly impacts appearance fruits. Considering extent damage, present study aimed understand impact Xa...
We have isolated and characterized a lytic double-stranded DNA Xanthomonas campestris pv. campestris bacteriophage (XTP1) capable of mediating generalized transduction. The phage transduces chromosomal markers at frequencies of 10(-5) to 10(-6) transductants per PFU. We demonstrated its genetic utility by the isolation and cotransduction of linked transposon insertions to a nonselectable locus,...
As a key virulence strategy to cause bacterial leaf blight, Xanthomonas oryzae pv. oryzae (Xoo) injects into the plant cell DNA-binding proteins called transcription activator-like effectors (TALEs) that bind to effector-binding elements (EBEs) in a sequence-specific manner, resulting in host gene induction. TALEs AvrXa7, PthXo3, TalC and Tal5, found in geographically distant Xoo strains, all t...
Xanthomonas vasicola pathovar vasculorum (Xvv) is the bacterial agent causing gumming disease in sugarcane. Here, we compare complete genome sequences for five isolates of Xvv originating from sugarcane and one from maize. This identified two distinct types of lipopolysaccharide synthesis gene clusters among Xvv isolates: one is similar to that of Xanthomonas axonopodis pathovar citri (Xac) and...
