Van Schalkwyk, Antoinette; Peter, Wenzl; Smit, Sandra; Lopez-Cobollo, Rosa; Kilian, Andrzej; Bishop, Gerard; Hefer, Charles Amadeus; Berger, David Kenneth (Springer, 2012)Marker-trait association studies in tomato have progressed rapidly due to the availability of several populations developed between wild species and domesticated tomato. However, in the absence of whole genome sequences ...

Muller, M.F.; Barnes, Irene; Kunene, N.T.; Crampton, Bridget Genevieve; Bluhm, B.H.; Phillips, Sonia M.; Olivier, Nicholas Abraham; Berger, David Kenneth (American Phytopathological Society, 2016-10)Muller, M.F., Barnes, I., Kunene, N.T., Crampton, B.G., Bluhm, B.H., Phillips, S., Olivier, N.A. and Berger, D.K. 2016. Cercospora zeina from maize in South Africa exhibits high genetic diversity and lack of regional ...

Meyer, Febe E.; Shuey, Louise S.; Naidoo, Sitha; Mamni, Thandekile B.; Berger, David Kenneth; Myburg, Alexander Andrew; Van den Berg, Noelani; Naidoo, Sanushka (Frontiers Research Foundation, 2016-03-02)Damage caused by Phytophthora cinnamomi Rands remains an important concern on forest tree species. The pathogen causes root and collar rot, stem cankers, and dieback of various economically important Eucalyptus spp. In ...

Naidoo, Sanushka; Fouche-Weich, Joanne; Law, P.; Denby, K.J.; Marco, Y.; Berger, David Kenneth (Wiley, 2011-04)Ralstonia solanacearum, the causal agent of bacterial wilt, has been reported from Eucalyptus plantations in at least three countries in Africa. The lack of genomics resources in Eucalyptus species led us to develop and ...

Oelofse, Dean; Gazendam, Inge; Veale, Adri; Djami-Tchatchou, Arnaud; Berger, David Kenneth; Dubery, Ian (Springer, 2016-12)A class-III chitinase promoter was isolated from Lupinus albus. The region 5′ to the coding sequence of the IF3 gene was amplified by gene walking and sequenced. The proximal 2.0 kb sequence contains a predicted promoter ...

Van der Linden, Liesl Elizabeth; Bredenkamp, Jane; Naidoo, Sanushka; Fouche-Weich, Joanne; Denby, Katherine J.; Genin, Stephane; Marco, Yves; Berger, David Kenneth (American Phytopathological Society, 2013-04)Bacterial wilt caused by Ralstonia solanacearum is a disease of widespread economic importance that affects numerous plant species, including Arabidopsis thaliana. We describe a pathosystem between A. thaliana and biovar ...

Berger, David Kenneth; Carstens, Maryke; Korsman, Jeanne Nicola; Middleton, Felix; Kloppers, Frederik J.; Tongoona, Pangirayi; Myburg, Alexander Andrew (BioMed Central, 2014-05-22)BACKGROUND: Gray leaf spot (GLS) is a globally important foliar disease of maize. Cercospora zeina, one of the two fungal species that cause the disease, is prevalent in southern Africa, China, Brazil and the eastern corn ...

Reitmann, Anandi; Berger, David Kenneth; Van den Berg, Noelani (Springer, 2017-01)Phytophthora cinnamomi is an economically important oomycete that infects more than 3,000 plant species. We aimed to identify the repertoire of genes expressed during preinfection stages by analysing an RNA-Seq library ...

Korsman, J.; Meisel, B.; Kloppers, Frederik J.; Crampton, Bridget Genevieve; Berger, David Kenneth (Springer, 2012)Grey leaf spot is an important maize foliar disease caused by the fungal pathogens Cercospora zeae-maydis and Cercospora zeina. Although methods exist to detect these Cercospora species in maize, current techniques do ...

Coetzer, Nanette; Gazendam, Inge; Oelofse, Dean; Berger, David Kenneth (BioMed Central, 2010-04)BACKGROUD: Suppression subtractive hybridization is a popular technique for gene discovery from non-model organisms without an annotated genome sequence, such as cowpea (Vigna unguiculata (L.) Walp). We aimed to use this ...

Christie, Nanette; Myburg, Alexander Andrew; Joubert, Fourie; Murray, Shane L.; Carstens, Maryke; Lin, Yao-Cheng; Meyer, Jacqueline; Crampton, Bridget Genevieve; Christensen, Shawn A.; Ntuli, Jean F.; Wighard, Sara S.; Van de Peer, Yves; Berger, David Kenneth (Wiley, 2017-02)We used a systems genetics approach to elucidate molecular mechanisms of maize responses to gray leaf spot (GLS) disease, caused by Cercospora zeina, a threat to maize production globally. Expression analysis of earleaf ...
