PsSat5, a cDNA clone from Pisum sativum cv. Alaska, contained a microsatellite consisting of 15 TCA repeats within the 59UTR. This SSR microsatellite was immediately upstream of the presumptive ATG start codon. PCR amplification of genomic DNA from cv. Alaska yielded an identical sequence. This repeat region was analyzed from 10 additional wild and cultivated accessions of Pisum and from four c...

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.

Forty-nine strains of the Fusarium oxysporum complex were isolated from five different sample locations within two neighboring pea fields. Of these, 39 strains were isolated from soil and 10 from pea plants showing symptoms of root rot. Twenty-eight of the isolates were tested for pathogenicity towards pea. Based on percentage discoloration of the roots and stem base, the isolates were divided ...

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....

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.

Physiological responses to infection by strains of Rhizobium leguminosarum which differed in their capacity to reduce N(2) were determined in 26-day-old pea plants (Pisum sativum L. cv. Alaska) grown under uniform environmental conditions in the absence of combined N. The highest N(2) reduction rates, calculated from H(2) evolution and C(2)H(2)-dependent C(2)H(4) production measurements, were a...

In many plant tissues, either an increase of protein and RNA synthesis or an increase in the incorporation of labeled precursors into these macromolecules in the target tissue is evoked by hormones.'-6 A few reports indicate that hormones may also enhance the RNA synthesis by isolated nuclei.7-'0 It has in no case been shown that the increased RNA synthesis is a primary effect of the hormone, a...

Barley and pea plants were grown under several regimens of different compositions of soil atmosphere, the O(2) concentration varying from 0 to 21% and the CO(2) concentration from 0 to 8%. In absence of CO(2), the effect of O(2) on root length in barley was characterized by equal root lengths within the range of 21 to 7% O(2) and a steep decline between 7 and 0%. In peas, while showing the same...

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...
