| cell surfaces in plant-microorganism interactions: ii. evidence for the accumulation of hydroxyproline-rich glycoproteins in the cell wall of diseased plants as a defense mechanism. | enrichment of the cell wall in hydroxyproline-rich glycoprotein is involved in the defense of muskmelon (cucumis melo) seedlings to colletotrichum lagenarium, the causative agent of anthracnose. the extent to which this accumulation proceeds may be experimentally modified by treating plants with ethylene or growing them in the presence of free l-trans-hydroxyproline. it appears that the increase in the wall hydroxyproline-rich glycoprotein mediated through ethylene is paralleled by an increasing ... | 1979 | 16660957 |
| enhancement of wound-induced ethylene synthesis by ethylene in preclimacteric cantaloupe. | although intact fruits of unripe cantaloupe (cucumis melo l.) produce very little ethylene, a massive increase in ethylene production occurred in response to excision. the evidence indicates that this wound ethylene is produced from methionine via 1-aminocyclopropanecarboxylic acid (acc) as in ripening fruits. excision induced an increase in both acc synthase and the enzyme converting acc to ethylene. ethylene further increased the activity of the enzyme system converting acc to ethylene. the in ... | 1982 | 16662200 |
| stereospecific conversion of 1-aminocyclopropanecarboxylic acid to ethylene by plant tissues : conversion of stereoisomers of 1-amino-2-ethylcyclopropanecarboxylic acid to 1-butene. | inasmuch as the molecule of 1-aminocyclopropanecarboxylic acid (acc) possesses reflective symmetry but lacks rotational symmetry, the two chemically alike methylene groups can be distinguished by a stereospecific enzyme. to determine whether acc conversion to ethylene by plant tissues proceeds in a stereospecific fashion, the four stereoisomers of 1-amino-2-ethylcyclopropanecarboxylic acid (aec) were administered to postclimacteric apple (malus sylvestris mill., var. golden delicious), excised p ... | 1982 | 16662444 |
| cell surfaces in plant-microorganism interactions : iv. fungal glycopeptides which elicit the synthesis of ethylene in plants. | the production of ethylene by melon (cucumis melo cv cantaloup charentais) tissues is stimulated during incubation in the presence of fungal glycopeptides extracted from colletotrichum lagenarium, a pathogen of melon. these glycopeptides, called elicitors of ethylene, are found in the mycelium, the cell wall, and the culture filtrate. elicitation of ethylene is a relatively early phenomenon and lasts for several hours. upon purification of the crude elicitor extract by gel filtration and ion exc ... | 1984 | 16663747 |
| promotion by ethylene of the capability to convert 1-aminocyclopropane-1-carboxylic acid to ethylene in preclimacteric tomato and cantaloupe fruits. | the intact fruits of preclimacteric tomato (lycopersicon esculentum mill) or cantaloupe (cucumis melo l.) produced very little ethylene and had low capability of converting 1-aminocyclopropane-1-carboxylic acid (acc) to ethylene. when these unripe tomato or cantaloupe fruits were treated with ethylene for 16 hours there was no increase in acc content or in ethylene production rate, but the tissue's capability to convert acc to ethylene increased markedly. such an effect was also observed in frui ... | 1985 | 16664067 |
| sucrose metabolism in netted muskmelon fruit during development. | sugar content and composition are major criteria used in judging the quality of netted muskmelon (cucumis melo l. var reticulatus) fruit. sugar composition and four enzymes of sucrose metabolism were determined in ;magnum 45' muskmelon fruit at 10-day intervals beginning 10 days after pollination (dap) until full-slip (35 dap). sugar content increased in both outer (green) mesocarp and inner (orange) mesocarp between 20 and 30 dap. the major proportion of total increase in sugar was attributed t ... | 1987 | 16665448 |
| water relations of seed development and germination in muskmelon (cucumis melo l.) : i. water relations of seed and fruit development. | total water potential (psi), solute potential, and turgor potential of field-grown muskmelon (cucumis melo l.) fruit tissue (pericarp) and seeds were determined by thermocouple psychrometry at 5-day intervals from 10 to 65 days after anthesis (daa). fruit maturity occurred between 44 and 49 daa, and seed germination ability developed between 35 and 45 daa. pericarp psi was essentially constant at approximately -0.75 megapascal (mpa) from 10 to 25 daa, then decreased to a minimum value of -1.89 m ... | 1988 | 16665921 |
| nutrient salts promote light-induced degradation of indole-3-acetic acid in tissue culture media. | the disappearance of indole-3-acetic acid (iaa) from cell-free liquid culture medium was followed in response to nutrient salts found in murashige-skoog salt base, light, and ph range of 4 to 7. the loss of iaa was accelerated by light or murashige-skoog salts. however, the combination of both light and murashige-skoog salts acted synergistically to catalyze the destruction of over 80% of the original iaa within 7 days of continuous incubation. under these same conditions, the loss of iaa was de ... | 1988 | 16666312 |
| a simple purification of indole-3-acetic acid and abscisic acid for gc-sim-ms analysis by microfiltration of aqueous samples through nylon. | a simple procedure was developed for the partial purification of plant tissue samples to be analyzed simultaneously for indole-3-acetic acid (iaa) and abscisic acid (aba). the procedure relies on removal of contaminants by filtration through nylon and partitioning into dichloromethane. this procedure successfully purified both iaa and aba from muskmelon, cotton, and broccoli tissue. twenty individual samples can be purified and methylated in 8 h for analysis of free iaa and aba with gas chromato ... | 1989 | 16666735 |
| sucrose phosphate synthase and acid invertase as determinants of sucrose concentration in developing muskmelon (cucumis melo l.) fruits. | fruits of orange-fleshed and green-fleshed muskmelon (cucumis melo l.) were harvested at different times throughout development to evaluate changes in metabolism which lead to sucrose accumulation, and to determine the basis of differences in fruit sucrose accumulation among genotypes. concentrations of sucrose, raffinose saccharides, hexoses and starch, as well as activities of the sucrose metabolizing enzymes sucrose phosphate synthase (sps) (ec 2.4.1.14), sucrose synthase (ec 2.4.1.13), and a ... | 1989 | 16667212 |
