“…following treatment with ethylene similar to that previously reported in potato tubers, fruits [15,16,17] and Iris bulbs [6,10] . A marked increase in respiration of isolated orchid petal cells was observed 10 to 14 h after the flower was subjected to a short-term C 2 H4 treatment .…”

“…The shift was enhanced by high O 2 concentration . An induction of cyanide resistant respiration by ethylene has been observed recently in Iris bulbs [10] in addition to that reported earlier in potato tuber and fruits [4,15,16,17] . With the Iris bulbs, induction of the development of cyanide resistant respiration by ethylene was maximal 24 h after C 2 H4 treatment.…”

“…Once developed, the cyanide resistant respiration in orchid flowers can withstand tissue disruption as observed previously [4,10] . The fact that cyanide resistant respiration can be induced in orchid tissues where the cyanide resistant capacity is normally absent or negligible is worth mentioning .…”

“…The development of cyanide resistant respiration is influenced by a number of factors, including ethylene and cyanide [4,10,15,16,17,18,19] . However, for the stimulation of respiration by ethylene, the existence of a cyanide resistant electron transport pathway is a prerequisite [15,16,17] .…”

Respiration of isolated Aranda orchid petal cells increased markedly after cut flowers were treated with ethylene . An increase in respiration was observed 15 to 20 h after treatment which was further enhanced in the presence of oxygen and ethylene . Ethylene induces the development of a cyanide resistant pathway in fully opened orchid flower tissues where the cyanide resistant capacity is negligible . However, there appears a shift back to the cyanide sensitive pathway some time after induction .

Osmotic dehydration of wheat seedlings in -0.5 MPa polyethylene glycol (PEG) solutions for 24, 48 and 72 h resulted in mild, moderate and severe water stress respectively in leaves, but only caused mild water stress in roots as reflected by the changes in relative water content (RWC). In response to the above water stress conditions, leaf total respiratory rate (V(t)) decreased progressively, and the alternative pathway (AP) capacity (V(alt)) and its actual operation activity (rhoV(alt)) decreased more severely. Water stress also led to continuous reduction in cytochrome pathway (CP) activity ((rho' V (cyt)) and different changes in the contribution of rhoV(alt) and rho'V(cyt) to V(t), in leaves, with rhoV(alt)/ V(t), decreasing and rho'V(cyt)/V(t) increasing. The change pattern of root V(t) was similar to that of its RWC, while root V(alt) and rhoV(alt) were found to decrease during the first 24 h of stress and thereafter recover to a level close to that of the control (0 h). These data indicate that the alternative pathway is sensitive to water stress and can adapt mild water stress. The results of northern hybridization using an alternative oxidase gene (Aox) as probe revealed that there was a good correlation between V(alt) (also rhoV(alt)) and Aox mRNA levels in both leaves and roots, suggesting that water stress affects the development and operation of AP respiration through affecting the expression of the alternative oxidase gene.
