Senescence-associated Gene Expression in Narcissus ‘dutch Master’
Flower senescence is a highly controlled developmental event that culminates in the death of the floral organs. Most research on flower senescence has focused on the perianth, since it typically determines the commercial life of the flower. The mechanism by which the perianth dies differs between species: in some flowers, wilting is the primary symptom of senescence whereas in others, the peria...
متن کاملIdentification of genes associated with perianth senescence in Daffodil (Narcissus pseudonarcissus
We used a PCR-based subtractive procedure to isolate genes that increased in abundance in the perianth of incipiently senescent daffodil (Narcissus pseudonarcissus L. ‘Dutch Master’) flowers. Using RNA gel blot analysis we confirmed that 18 of the transcripts were senescence-associated. A number of these have homologs in previously-studied senescing floral and leaf tissue systems (cysteine prot...
متن کاملFlower development and senescence in Narcissus tazetta ‘Kashmir Local’
Flower development and senescence was studied in Narcissus tazetta ‘Kashmir Local’. Flower development was divided into six stages (I-VI), from the tight bud stage to the senescent stage. Flower fresh and dry weight increased as the flowers progressed from bud to bloom and then declined during senescence. Membrane permeability of tepal tissues increased as the flower progressed through various ...
متن کاملSenescence-associated gene expression during ozone-induced leaf senescence in Arabidopsis.
The expression patterns of senescence-related genes were determined during ozone (O(3)) exposure in Arabidopsis. Rosettes were treated with 0.15 microL L(-1) O(3) for 6 h d(-1) for 14 d. O(3)-treated leaves began to yellow after 10 d of exposure, whereas yellowing was not apparent in control leaves until d 14. Transcript levels for eight of 12 senescence related genes characterized showed induc...
متن کاملSenescence-Associated Gene Induced by Darkness1
A nearly full-length cDNA was isolated from a cDNA library prepared from incipiently senescent radish (Raphanus sativus L.) cotyledons using a previously isolated cDNA clone for darkinducible mRNA as a probe (A Watanabe, N Kawakami, Y Azumi [1989] In Cell Separation in Plants, NATO ASI Series, Vol H35, pp 31-38. Springer-Verlag, Berlin). The clone detected transcripts of 800 bases which increas...
