Nonclimacteric Fruit

Grape (Vitis vinifera L.) berries are considered to be nonclimacteric fruit as they do not exhibit a large rise in ethylene production or respiration rate at the onset of ripening (veraison). However, ethylene may still play a role in berry development and in ripening in particular. (2-Chloroethyl)phosphonic acid (CEPA), an ethylene-releasing reagent, delayed ripening when applied early in berry development. In agreement with a role for ethylene in controlling the timing of ripening, the application of an inhibitor of ethylene biosynthesis, aminoethoxyvinylglycine (AVG), advanced ripening, as did abscisic acid, when applied during the preveraison period. Applications of CEPA nearer to the time of veraison enhanced berry colouration. Changes in the expression of ethylene biosynthesis and receptor genes were observed throughout berry development. Transcript levels of some of these genes were increased by CEPA and decreased by AVG, suggesting changes in ethylene synthesis and perception during the preveraison period that might contribute to the biphasic response to CEPA (ethylene). The significant delay of ripening in field-grown grapes through the application of CEPA also indicates that this may be useful in controlling the timing of veraison, and therefore harvest date, in warmer climates.

The Common

Treatment of cut `Master' carnations (Dianthus caryophyllus L.) with 50 mm aminotriazole (ATA) in distilled water for 5 days retarded senescence, increased flower longevity by 4 days compared to the control carnations kept in distilled water and inhibited the climacteric peak of ethylene production normally produced during the senescence of these flowers. The treatment had no effect, however, on the levels of the polyamines putrescine and spermidine. Thus, the biosynthetic routes of ethylene and polyamines may not compete for the common precursor S-adenosylmethionine (SAM). Also, in the petals of the control carnations, increased ethylene production was correlated with increased ion leakage and abscisic acid (ABA) levels. In the ATA treated petals, ion leakage and ABA levels increased later and reached values less than 50% compared to the control carnations. Chemical names used: abscisic acid (ABA), 3-1H-amino-1,2,4-triazole-1-yl (aminotriazole), 1-aminocyclopropane-1-carboxylic acid (ACC), S-adenosyl methionine (SAM).

Purple ornamental cabbage (Brassica oleracea var. acephala) is a popular decorative plant, cultivated for its colorful leaf rosettes that persist in cool weather. It is characterized by green outer leaves and purple inner leaves, whose purple pigmentation is due to the accumulation of anthocyanin pigments. Phytohormones play important roles in anthocyanin biosynthesis in other species. Here, we identified 14 and 19 candidate genes putatively involved in abscisic acid (ABA) and ethylene (ET) biosynthesis, respectively, in B. oleracea. We determined the expression patterns of these candidate genes by reverse-transcription quantitative PCR (RT-qPCR). Among candidate ABA biosynthesis-related genes, the expressions of BoNCED2.1, BoNCED2.2, BoNCED6, BoNCED9.1, and BoAAO3.2 were significantly higher in purple compared to green leaves. Likewise, most of the ET biosynthetic genes (BoACS6, BoACS9.1, BoACS11, BoACO1.1, BoACO1.2, BoACO3.1, BoACO4, and BoACO5) had significantly higher expression in purple compared to green leaves. Among these genes, BoNCED2.1, BoNCED2.2, BoACS11, and BoACO4 showed particularly strong associations with total anthocyanin content of the purple inner leaves. Our results suggest that ABA and ET might promote the intense purple pigmentation of the inner leaves of purple ornamental cabbage.
