Copper-catalyzed yne-allylic substitutions: concept and recent developments

Beilstein Journal of Organic Chemistry
The catalytic (asymmetric) allylation and propargylation have been established as powerful strategies allowing access to enantioenriched α-chiral alkenes and alkynes.

Induction of Hypersensitive Response and Nonhost Resistance by a Cladosporium fulvum Elicitor CfHNNI1 is Dose-Dependent and Negatively Regulated by Salicylic Acid

Journal of Integrative Agriculture, 2012
Nonhost resistance is a phenomenon that enables plants to protect themselves against the majority of potential pathogens, and thus has a great potential for application in plant protection. We recently found that CfHNNI1 (for Cladosporium fulvum host and

Two Distinct Types of Spherulite in Poly (ethylene oxide) [PDF]

, 1966
Fujiwara's oriented crystallization method was applied to poly (ethylene oxide) to obtain a uniform texture composed of parallel fibrils which correspond to the structure of a radial direction of spherulites.

Regulatory Function of Polyamine Oxidase-Generated Hydrogen Peroxide in Ethylene-Induced Stomatal Closure in Arabidopsis thaliana

Journal of Integrative Agriculture, 2013
Hydrogen peroxide (H2O2) is an important signaling molecule in ethylene-induced stomatal closure in Arabidopsis thaliana. Early studies on the sources of H2O2 mainly focused on NADPH oxidases and cell-wall peroxidases.

Ethylene-Induced Postharvest Changes in Five Chinese Bayberry Cultivars Affecting the Fruit Ripening and Shelf Life

Horticulturae
Ethylene is an essential indicator of fruit ripening and climacteric or non-climacteric nature. This study investigated the postharvest behavior of five Chinese bayberry cultivars ‘Biqi’, ‘Dongkui’, ‘Fenhong’, ‘Xiazhihong’, and ‘Shuijing’.

Involvement of ethylene signalling in a non-climacteric fruit: new elements regarding the regulation of ADH expression in grapevine [PDF]

, 2004
Although grape berries have been classified as non climacteric fruits, ongoing studies on grape ethylene signalling lead to challenge the role of ethylene in their ripening. One of the significant molecular changes in berries is the up regulation of ADH

Ethylene, a Signaling Compound Involved in Seed Germination and Dormancy

Plants
The present review is focused on current findings on the involvement of ethylene in seed biology. The responsiveness of seeds to ethylene depends on the species and the dormancy status, improving concentrations ranging from 0.1 to 200 μL L−1.

Production of mutants affected in hormone signalling to dissect defence mechanisms in Hevea brasiliensis: the case of ethylene [PDF]

, 2012
Production of mutants by genetic transformation is one alternative to dissect the response to hormonal treatment. Ethylene is an important plant hormone involved in latex production.

Morphological changes of lenticels and their role in gas exchange and sprouting physiology of potato tubers during postharvest storage

Frontiers in Plant Science
The application of exogenous gases has been used to suppress sprouting in stored potato tubers. However, their efficacy in extending ecodormancy largely depends on achieving optimal gas exchange between the storage atmosphere and the tuber itself.

Postharvest characteristics of cut flowers of selected members of the family Myrtaceae : a thesis presented in fulfilment of the requirements for the degree of Master of Philosophy at Massey University, New Zealand [PDF]

, 1999
Stages of floral development were described for Eucalyptus ficifolia and Metrosideros collina 'Tahiti' flowers (Myrtaceae) attached and detached from plants.
