Isolation and Characterization of the Pigment Esters of Xanthomonas juglandis (campestris)

Isolation and characterization of a porin-like outer membrane protein from Xanthomonas campestris pv. campestris.

Xanthomonas campestris pv. campestris, a plant-associated pathogenic bacterium, is the causal agent of foliar spots and blights in crucifers. The major outer membrane protein, Omp37, of 37 kDa, has been identified, purified to homogeneity, and its characterization has also been carried out. Native Omp37 behaved as a trimer, as revealed by gel filtration and SDS-PAGE. FTIR measurements revealed ...

Isolation and characterization of a generalized transducing phage for Xanthomonas campestris pv. campestris.

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,...

extraction and characterization of allium irancum plant extract and its application in the green synthesis of silver nano particles and oxidation of thiocarbony1 compounds

سنتز سبز نانوذرات فلزی (nps) درسالهای اخیر توجه بسیارزیادی را به خود جلب کرده است. زیرا این پروتوکل کم هزینه وسازگار با محیط زیست از روش های استاندارد سنتز. در این پایان نامه ما گزارش میکنیم یک روش ساده و سازگار با محیط زیست برای سنتز نانوذرات نقره با استفاده از محلول آبی عصاره گیاه allium iranicum به عنوان یک عامل کاهش دهنده ی طبیعی. نانو ذرات نقره مشخص شد با استفاده از تکنیک های uv-visible، x...

Walnut Blight: Genetic Variation in English Walnut in Response to Inoculation with Xanthomonas Campestris Pv. Juglandis

This was the second year of a study which evaluated the genetic variation among English walnut germplasm in response to infection by Xanthomonas campestris pv. juqlandis (Xcj), the bacterium which causes the disease walnut blight. Immature leaves and nuts of 10 walnut accessions representing the breadth of currently available germplasm were inoculated. Leaves were scored for disease severity at...
