Heterologous expression of Arabidopsis ERS1 causes delayed senescence in coriander

The phytohormone ethylene is involved in many developmental processes, including leaf and flower senescence. Ethylene is perceived by plants through receptors that trigger the downstream signal transduction pathway. The mutated ethylene receptor ERS1 (ethylene response sensor) from Arabidopsis is of a dominant negative nature and confers ethylene insensitivity in Arabidopsis. To investigate if the altered ERS1 gene can affect the tissue senescence in heterologous plants, we introduced it into coriander by Agrobacterium-mediated transformation. Transgenic plants were regenerated by cocultivating hypocotyl segments with A. tumefaciens harboring binary vector pCGN1547 that carried the ERS1 gene. The presence and expression of the transgene were confirmed by genomic Southern blot and reverse transcriptase-PCR analyses. Leaf and flower senescence were delayed significantly in the transgenic plants. The ability of the mutated ERS1 gene to confer the ethylene-insensitive phenotype can be exploited for extending the shelf-life of leafy vegetables.

Involvement of ethylene on growth and plant regeneration in callus cultures of Heliconia psittacorum L.f.

The level of ethylene accumulated in morphogenic callus cultures of Heliconia psittacorum L.f. was only one quarter that of non-morphogenic cultures. The rate of ethylene production in the morphogenic callus cultures during early stages of differentiation of protocorm-like bodies leading to plantlet regeneration was lo-fold higher than that during callus proliferation. In cultures sealed with gastight serum caps, fresh weight gain was reduced 2-to 3-fold compared to those that were closed with Kaput&). Treatment with l-aminocyclopropane-1-carboxylic acid (2 100 PM) caused complete inhibition of plant regeneration from the morphogenic callus on subsequent culture under inductive conditions. Silver nitrate and aminoethoxyvinylglycine also reduced plant regeneration. These results indicate that while high levels of ethylene were inhibitory, a low level of endogenous ethylene production may be necessary during the plant regeneration phase in callus cultures of Heliconia.Abbreviations: 24-D = 2,4-dichlorophenoxyacetic acid; AC = activated charcoal; ACC = 1 -aminocyclopropane-I-carboxylic acid; AVG = aminoethoxyvinylglycine; BM = basal medium; CH = casein hydrolysate; DM = development medium; MM = maintenance medium; PLB = protocorm-like body
