The 2012 RUFORUM Biennial Conference is the third in the series. The main objective of the Biennial conferences is to provide a platform for agricultural research for development stakeholders in Africa and beyond to actively exchange findings and experiences, while at the same time learning lessons towards improving performance of the agricultural sector and ultimately people’s livelihoods. The biennial conference is RUFORUM’s most comprehensive meeting for the diversity of stakeholers in agriculture. It is especially dedicated to graduate students and their supervisors, grantees in RUFORUM member universities and alumni. It is a platform for peer review, quality control, mentorship, networking and shared learning. The third Biennial Conference was attended by 657 participants.This record contains an extended abstract accepted under Integrated Crop Management
Potential Application of Natural Variability of Arabidopsis Thaliana Accessions in Genomics of Xanthomonas Campestris pv Pusacearum
Abstract:
The banana Xanthomonas wilt epidemic in the Great Lake
region of Africa has destroyed banana and is affecting
livelihoods of thousands of people who depend on the crop.
Currently, there are no banana varieties resistant to the disease.
Genetic engineering is the most feasible approach to introduce
resistance to the disease in banana. This however requires a
good understanding of the underlying genomics of the bacterium.
In this study, the capacity of Arabidopsis thaliana to study
Xanthomonas strain diversity was evaluated. Two isolates of
Xanthomonas campestris (Xcm2251, Xcm4383) and one
isolate of Xanthomonas vasicola (Xvv206) were infiltrated
into four A. thaliana genotypes. There was variable response
by A. thaliana accessions towards the three bacterial strains.
The effect of Xanthomonas strains was also significant. It is
concluded that A. thaliana can be used for host pathogen
interaction studies of Xcm and Xvv.
L’épidémie de fanage Xanthomonas de la banane dans la région
des Grands Lacs de l’Afrique a détruit la banane et affecte les
moyens de subsistance de milliers de personnes qui dépendent
de la culture. Actuellement, il n’existe pas de variétés de
bananes qui résistent à cette maladie. Le génie génétique est
l’approche la plus réaliste pour l’introduction de la résistance à
la maladie de la banane. Cela exige toutefois une bonne
compréhension de la génomique sous-jacente de la bactérie.
Dans cette étude, la capacité d’Arabidopsis thaliana pour
étudier la diversité des souches de Xanthomonas a été évaluée.
Deux isolats de Xanthomonascampestris (Xcm2251,
Xcm4383) et un isolat de Xanthomonasvasicola (Xvv206) ont
été infiltrés en 4 génotypes de A. thaliana. Il y avait une réponse
variable par les adhésions de A. thaliana vers les trois souches
bactériennes. L’effet des souches de Xanthomonas étaitégalement significatif. Il est conclu que A. thaliana peut être
utilisé pour des études hôte d’interaction des agents pathogènes
de Xcm et Xvv.
