The predominant root-knot nematode in New Zealand pastures is Meloidogyne trifoliophila, and a recurrent selection program in Trifolium repens has developed resistance to this species. No data are available, however, on the mechanisms of resistance in T. repens or resistant genotypes of T. semipilosum. The development of M. trifoliophila in roots of T. repens and T. semipilosum was examined wee...
The wheat gene Lr34 confers durable and partial field resistance against the obligate biotrophic, pathogenic rust fungi and powdery mildew in adult wheat plants. The resistant Lr34 allele evolved after wheat domestication through two gain-of-function mutations in an ATP-binding cassette transporter gene. An Lr34-like fungal disease resistance with a similar broad-spectrum specificity and durabi...
Abstract Leaf rust is a common and costly wheat disease. The introduction of resistance genes derived from wild relatives one way to improve disease control. However, due the rapid development virulence in casual pathogen Puccinia triticina , long-term effectiveness some leaf ( Lr ) questionable. To assess this, we examined 130 accessions 13 relative species Aegilops genus. presence 9 was deter...
