Ethylene receptors and regulatory control. The mode of action of ethylene at the molecular level is unknown. Some attempts, however, have been made to determine the receptor sites for ethylene (54) as well as their characteristics (55). There appears to be very little incorporation of ethylene applied to tissues (only about 0.05%). The - - C ethylene incorporated into pea seedling tissues which responded physiologically to the gas was metabolized to C02 and water-soluble metabolites (55). Metabolism of the incorporated ethylene by pea seedlings and other tissues was inhibited by high levels of CO2 (7-10%) and Ag+ ions (10-500 ppm) (56). Ag+ ions prevented the incorporation of ethylene into water-soluble tissue metabolites and...

Eukaryotes quantitated in various plants e.g. Phaseolus vulgaris, Pisum sativum (Fabaceae) fea mays (Poaceae) seedling tissues involvement in plant defence stomatal opening Annona squamosa (Annonaceae), Dicentra eximia, Corydalis ambigua (Fumariaceae), Beilschmiedia podagrica (Lauraceae), Eschscholzia californica, Glauciumflamm (Papaveraceae)... 

Table II. Effects of ALA (5mM) plus DP (15 mM) on porphyrin accumulation in seedling tissues of several plant species. Plant were assayed for porphyrins after being sprayed with the herbicides and incubated in darkness for 17 h. Herbicidal damage was assessed 10 days after porphyrins were assayed and subsequent exposure to greenhouse light conditions. Taken from ref. (5).

Activity of phosphofructokinase and fructose 1,6-diphosphatase in mammals can be finely controlled within the cell to regulate glycolysis and gluconeogenesis, and there is some evidence to suggest a similar control mechanism in seedling tissues [53a]. 

Figure 1. LOX activity in seed and seedling tissues of soybean mutants. Enzyme was extracted in ca. 4 volumes of 20 mM sodium phosphate buffer, pH 6.8. What we designate as line A is mutant for LOX 2 and 3 line B is mutant for LOX 1 and 3 line C is mutant for LOX 2 line D is mutant for LOX 3 line E mutant for LOX 1 and F is the wildtype recurrent parent, the soybean cultivar Century. ... 

Northern analyses of RNA isolated from various organs of maize identified the gl8 mRNA as a 1.4 kb band (Fig. 3). In homozygous gl8/gl8 seedlings the accumulation of the gl8 mRNA is reduced to between 1/3 and 1/5 of the level in found in wild-type seedlings (Fig. 3). In wild-type plants the gl8 mRNA is detectable in all organs examined, however, maximum accumulation occurs in seedling tissue (Fig. 3).
