“…Further case examples are required. Being a major plant growth regulator and ripening hormone, ethylene is considered to be involved in the softening of apples [41,52]. Internal ethylene concentration (IEC) was measured in relation to watercore degree.…”

Watercore is a so-called physiological disorder of apple (Malus domestica L.) that commonly occurs in several well-known cultivars. It is associated with a rapid softening of the flesh that causes a marked changed in flavor and texture. In Asia, apples with watercore are preferred and considered a delicacy because of their enhanced sweet flavor. The ‘Fuji’ cultivar, the first cultivar with rich watercore that is free from texture deterioration, has played a key role in the development of the market for desirable watercored apples. This review aimed to summarize and highlight recent studies related to the physiology of watercore in apples with special focus on ‘Fuji’ and related cultivars.

“…The protein ACS is a pyridoxal‐5′‐dependent enzyme encoded by a multigene family and is considered the main regulating enzyme of the ethylene biosynthesis (Argueso et al ). Regulation can take place at the transcriptional as well as at the post‐translational level (Tatsuki ). ACC can be converted into the biologically inactive 1‐(malonylamino)cyclopropane‐1‐carboxylic acid (MACC) by ACC n ‐malonyl transferase (Hoffman and Yang ) or ethylene by 1‐aminocyclopropane‐1‐carboxylate oxidase (ACO; Adams and Yang 1979).…”

In this study, the short-term and dynamic changes of the ethylene biosynthesis of Jonagold apple during and after application of controlled atmosphere (CA) storage conditions were quantified using a systems biology approach. Rapid responses to imposed temperature and atmospheric conditions were captured by continuous online photoacoustic ethylene measurements. Discrete destructive sampling was done to understand observed changes of ethylene biosynthesis at the transcriptional, translational and metabolic level. Application of the ethylene inhibitor 1-methylcyclopropene (1-MCP) allowed for the discrimination between ethylene-mediated changes and ethylene-independent changes related to the imposed conditions. Online ethylene measurements showed fast and slower responses during and after application of CA conditions. The changes in 1-aminocyclopropane-1-carboxylate synthase (ACS) activity were most correlated with changes in ACS1 expression and regulated the cold-induced increase in ethylene production during the early chilling phase. Transcription of ACS3 was found ethylene independent and was triggered upon warming of CA-stored apples. Increased expression of ACO1 during shelf life led to a strong increase in 1-aminocyclopropane-1-carboxylate oxidase (ACO) activity, required for the exponential production of ethylene during system 2. Expression of ACO2 and ACO3 was upregulated in 1-MCP-treated fruit showing a negative correlation with ethylene production. ACO activity never became rate limiting.

“…The last two reactions are catalyzed by ACC synthase and ACC oxidase, which have been shown to be encoded by multi-gene families with spatial and temporal regulation by various endogenous cues and environmental stimuli (Fluhr and Mattoo, 1996;Jones and Woodson, 1999a;Nakatsuka et al, 1998;Shibuya and Ichimura, 2010;Yangkhamman et al, 2007). Recent reports suggest that ACC synthase activity is also regulated post-translationally (Lin et al, 2009;Tatsuki, 2010).…”

Flower longevity is one of the most important traits for ornamental plants. Ethylene plays a crucial role in petal senescence in many plant species. Genes involved in ethylene biosynthesis, ethylene perception, and its signal transduction have been identified in several ornamental plants. Genetic modification of ethylene signaling genes has successfully improved flower longevity in several plant species. In contrast, regulatory mechanisms of petal senescence in flowers that show ethylene-independent senescence remain largely unknown. Japanese morning glory (Ipomoea nil) is a proposed model plant for ethylene-independent petal senescence, and an important role of autophagy in petal senescence has been highlighted in this plant. This review focused on our recent findings on ethylene signaling and our attempts to identify factors regulating ethylene-independent petal senescence.
