“…Numerous other loci have been identified through mutation studies [204]. Although the lack of common markers has made it difficult, consensus among QTL studies are consistent with early Mendelian analyses and show that QTL on LGII and LGIII correspond to known positions of the Lf and Hr loci [204][205][206]. Lf was the first locus controlling flowering in pea to be cloned and was identified through a candidate gene approach as a homolog of the Arabidopsis inflorescence identity gene TFL1 [207].…”

Pea (Pisum sativum L.) was the original model organism used in Mendel's discovery (1866) of the laws of inheritance, making it the foundation of modern plant genetics. However, subsequent progress in pea genomics has lagged behind many other plant species. Although the size and repetitive nature of the pea genome has so far restricted its sequencing, comprehensive genomic and post genomic resources already exist. These include BAC libraries, several types of molecular marker sets, both transcriptome and proteome datasets and mutant populations for reverse genetics. The availability of the full genome sequences of three legume species has offered significant opportunities for genome wide comparison revealing synteny and co-linearity to pea. A combination of a candidate gene and colinearity approach has successfully led to the identification of genes underlying agronomically important traits including virus resistances and plant architecture. Some of this knowledge has already been applied to marker assisted selection (MAS) programs, increasing precision and shortening the breeding cycle. Yet, complete translation of marker discovery to pea breeding is still to be achieved. Molecular analysis of pea collections has shown that although substantial variation is present within the cultivated genepool, wild material offers the possibility to incorporate novel traits that may have been inadvertently eliminated. Association mapping analysis of diverse pea germplasm promises to identify genetic variation related to desirable agronomic traits, which are historically difficult to breed for in a traditional manner. The availability of high throughput 'omics' methodologies offers great promise for the development of novel, highly accurate selective breeding tools for improved pea genotypes that are sustainable under current and future climates and farming systems.

“…Four natural and induced classes of alleles are known-Lf-d , Lf , lf , and lf-a -that in maximal inductive conditions confer minimum nodes of flowering of 15, 11, 8, and 5, respectively. The dominance order is Lf-d Ͼ Lf Ͼ lf Ͼ lf-a , with the lf-a allele being recessive (Murfet, 1975). LF is active in the shoot, and the different alleles determine the threshold of sensitivity of the apical meristem to flowering signals.…”

DETERMINATE and LATE FLOWERING Are Two TERMINAL FLOWER1/CENTRORADIALIS Homologs That Control Two Distinct Phases of Flowering Initiation and Development in Pea

Genes in the TERMINAL FLOWER1 ( TFL1 ) /CENTRORADIALIS family are important key regulatory genes involved in the control of flowering time and floral architecture in several different plant species. To understand the functions of TFL1 homologs in pea, we isolated three TFL1 homologs, which we have designated PsTFL1a , PsTFL1b , and PsTFL1c . By genetic mapping and sequencing of mutant alleles, we demonstrate that PsTFL1a corresponds to the DETERMINATE (
