Lr21 diversity unveils footprints of wheat evolution and its new …
网页2021年7月1日 · Lr21 is a leaf rust resistance gene, which did not enter the initial gene flow from Ae. tauschii into hexaploid wheat due to restrictive hybridization events. Here, we used population genetics and high-resolution comparative genomics to study evolutionary and functional divergence of Lr21 in diploid and hexaploid wheats.

Leaf rust resistance gene Lr21 - MASWheat
网页2019年7月27日 · Leaf rust resistance gene Lr21. Contributed by Allan Fritz. Aegilops tauschii, the D-genome progenitor of common wheat (Triticum aestivum), has been a rich source for resistance to Puccinia triticina. To date, six named genes have been described (reviewed in ref. 1, 2). One of the first genes transferred was Lr21 (3).
Map-based cloning of leaf rust resistance gene Lr21 from the …
网页Cloning of Lr21 was confirmed by genetic transformation and by a stably inherited resistance phenotype in transgenic plants. Lr21 spans 4318 bp and encodes a 1080-amino-acid protein containing a conserved nucleotide-binding site (NBS) domain, 13 imperfect leucine-rich repeats (LRRs), and a unique 151-amino-acid sequence missing from known NBS ...

Identification of leaf rust resistance loci in hard winter ... - bioRxiv
网页1 天前 · Leaf rust, caused by Puccinia triticina (Pt), is a serious constraint to wheat production. Developing resistant varieties is the best approach to managing this disease. Wheat leaf rust resistance (Lr) genes have been classified into either all-stage resistance (ASR) or adult-plant resistance (APR). The objectives of this study were to identify sources of leaf rust resistance in contemporary U ...
