A total of 122 accessions of different wild and cultivated Pisum sp. were analysed using retrotransposon-based insertion polymorphisms (RBIP) markers. The Pisum materials included wild and cultivated (landraces and cultivars) materials from the World core collection of the John Innes Centre (JI) representing all generally recognized Pisum taxa, landraces materials from the Spanish core collecti...

Renaturation of pea (Pisum sativum) DNA has been used to estimate the size of the pea genome and the fraction of pea DNA containing repeated DNA sequences. Pea DNA renaturation and single copy tracer renaturation indicate that the size of the pea genome is 0.5 picograms. More than 70% of pea DNA sequences are repeated from 100 to 5,000 times.

UNLABELLED PREMISE OF THE STUDY Novel markers were developed for pea (Pisum sativum) from pea expressed sequence tags (ESTs) having significant homology to Medicago truncatula gene sequences to investigate genetic diversity, linkage mapping, and cross-species transferability. • METHODS AND RESULTS Seventy-seven EST-derived genic markers were developed through comparative mapping between M....

The response of pea (Pisum sativum cv. Avola) to arbuscular micorrizal fungi (AM) species Glomus mosseae and Glomus intraradices and Rhizobium leguminosarum bv. Viciae, strain D293 regarding growth, nodulation and nitrogen fixing activity was studied. Pea plants (Pisum sativum cv. Avola) were grown in a glasshouse until flowering stage (35 days) in 4 kg plastic pots using leached cinnamonic for...

Rhizobium leguminosarum bv. viciae RCAM1026 is a strain first isolated in 1964 from nodules of "Ramensky 77" cultivar of garden pea (Pisum sativum L.) now routinely used as a model strain in inoculation experiments on pea. Assembly with SPAdes yielded 133 contigs longer then 200 bp (N50 = 202,321, GC% = 60.84). Resulting annotated genome is 7,248,686 bp encoding 6792 genes.

Indole-3-acetic acid levels are diminished about 50% in 5- to 6-day-old epicotyls of etiolated pea (Pisum sativum L.) seedlings treated with 10 to 36mul/l ethylene for 18 to 24 hr.

Gibberellic acid increases the level of RNA polymerase associated with chromatin isolated from expanding internodes of light-grown, dwarf pea plants (Pisum sativum L.), without a detectable increase in the amount of DNA template available.

Aphids are piercing-sucking insect pests and feed on phloem sap. During feeding, aphids inject a battery of salivary proteins into host plant. Some of these proteins function like effectors of microbial pathogens and influence the outcome of plant-aphid interactions. The pea aphid (Acyrthosiphon pisum) is the model aphid and encompasses multiple biotypes each specialized to one or a few legume ...

Smýkal P. (2014): Pea (Pisum sativum L.) in biology prior and after Mendel’s discovery. Czech. J. Genet. Plant Breed., 50: 52–64. Pea (Pisum sativum L.) has been extensively used in early hybridization studies and it was the model organism of choice for Mendel’s discovery of the laws of inheritance, making pea part of the foundation of modern genetics. Pea has also been used as model for experi...

Field pea (Pisum sativum L.) and wheat (Triticum sativum L.) were either sole cropped or intercropped in a complete design of five relative proportions and five density levels to determine the effects of interspecific interaction in an intercrop on wheat baking quality. It is shown how pea interspecific competitive ability for factors such as light and water results in an increase in wheat prot...
