Cloning, characterization and regulation of expression of a cold-acclimation-specific gene, cas18, in a freezing tolerant cultivar of alfalfaWolfraim, Lawrence A. (Lawrence Allen) January 1992 (has links)
Cold-acclimation-specific (CAS) gene expression was examined by screening a cDNA library prepared from poly(A)$ sp+$ RNA of cold-acclimated seedlings of a freezing-tolerant variety of alfalfa (Medicago falcata cv Anik). Three distinct CAS cDNA clones, pSM784, pSM2201, and pSM2358 were isolated. The genes corresponding to all three clones are coordinately induced by cold. Expression of these genes is not triggered by other stress treatments such as heat shock, water stress, wounding, or treatment with exogenous ABA. A positive correlation was observed between the level of expression of each gene and the degree of freezing tolerance of four alfalfa cultivars. / A full-length cDNA clone for the most abundantly-expressed gene, cas18 was isolated and sequenced. The deduced polypeptide, CAS18, is relatively small (167 amino acids), is highly hydrophillic, rich in glycine and threonine, and contains two distinctive repeat elements. It exhibits homology with members of the LEA/RAB/Dehydrin gene family--proteins which accumulate in response to water stress or abscisic acid (ABA). The cas18 cDNA hybridizes to three transcripts of 1.6, 1.4 and 1.0 kb in cold acclimated seedlings and cell cultures. The clone described here, Acs784, corresponds to the 1.0 kb transcript. / Expression of this gene is 30-fold greater in cold-acclimated cells than in nonacclimated cells after one week of low temperature treatment. Return to room temperature (deacclimation) results in the rapid disappearance of the three transcripts within just 5 hours. Studies of nuclear "run-on" transcription and transcript stability show that low temperature regulates the expression of cas18 at both the transcriptional and post-transcriptional levels.

Control of Dodder in Alfalfa Seed CropsLee, William Orvid 01 May 1954 (has links)
Dodder (Cuscuta spp.) is a parasitic weed which attacks alfalfa, clovers, lespedeza and many other species of plants. This pest is especially troublesome when these crops are grown to produce seed.
