Gibberellic acid stimulates lipid metabolism in barley aleurone protoplasts

1991

Abstract Changes in the lipid composition of barley aleurone protoplasts following incubation in the presence or absence of gibberellic acid (GA) were studied and correlated with cell development. Analysis of neutral lipids in protoplast extracts and purified lipid bodies provide evidence for the strong effect of GA on the mobilization of storage lipids. In vivo protoplast staining with the membrane marker N -phenyl-l-naphthylamine (NPN) and phospholipid determinations of protoplast extracts show an increase in membrane lipids during protoplast incubation. GA stimulates phospholipid metabolism by increasing the synthesis of phosphatidyl ethanolamine and phosphatidyl choline, the major phosp…

Effects of Ga3 and Ca2+ on barley aleurone protoplasts: a freeze-fracture study

1988

Freeze-fracture electron microscopy was used to study changes in the endomembrane system of barley (Hordeum vulgare L. cv. Himalaya) aleurone protoplasts. Protoplasts were used for this study because their response to calcium and the plant hormone gibberellic acid (Ga3) can be monitored prior to rapid freezing of cells for electron microscopy. Protoplasts incubated in Ga3 plus Ca2+ secrete elevated levels of a-amylase relative to cells incubated in Ga3 or Ca2+ alone. The endoplasmic reticulum (ER) and Golgi apparatus of protoplasts incubated in Ga3 plus Ca2+ undergo changes that are well correlated with the synthesis and secretion of a-amylase. The ER, which appears as short, single sheets …

Ética de las capacidades y desarrollo local. Una aplicación de economía, política pública y gobernanza

2015

Las ciudades europeas, cuna de la civilización urbana, se enfrentan a los retos de adaptarse y liderar la transformación del desarrollo urbano consecuencia de la transformación de la base productiva local a través del uso de la tecnología digital, la economía del conocimiento y la sociedad en red. El sistema urbano europeo del siglo XXI, multipolar, caracterizado por ciudades de tamaño medio, está configurando una nueva dimensión de la ciudad a través de nuevas grandes áreas funcionales, necesarias para competir en una economía globalizada. Las regiones metropolitanas, han generado un intenso debate tanto en el mundo académico como en los dirigentes locales sobre el modelo de ciudad que per…

Effetti delle epoche e modalità di concimazione su produzione e qualità del finocchio. Effects of time and method of fertilizer application on yield …

2010

Two field trials were carried out in Sicily during fall-winter and spring season to determine the influence of 9 fertilization treatments, obtained by changing the time (pre-plant and/or post-plant fertilization), and method (broadcast fertilization and/or fertigation) of fertilizer application and the type of fertilizer (mineral, organic, slow release fertilizers) on yield and quality of fennel. An unfertilized treatment (control) was also included. In all fertilized treatments, macronutrients were applied at the following total rates (kg ha-1): N (350), P2O5 (100), K2O (208). In both trials the highest yield and mean bulb weight was obtained by pre-planting application of all mineral fert…

Chemical composition of the essential oil from different vegetative parts of Foeniculum vulgare subsp. piperitum (Ucria) Coutinho (Umbelliferae) grow…

2021

In the present study, the chemical compositions of the essential oils from roots, stems, leaves and fruits of Foeniculum vulgare subsp. piperitum collected in Sicily were evaluated by GC and GC-MS. The main components of the roots were terpinolene (33.15%), gamma-terpinene (12.18%) and fenchyl acetate (11.23%). Stems and leaves were very rich in alpha-phellandrene (36.85% and 41.59%, respectively) and beta-phellandrene (19.68% and 25.79%, respectively), whereas the main components of fruits were terpinolene (20.10%) and limonene (17.84%)These results were compared with those of the EOs of the same vegetative parts of Foeniculum vulgare subsp. vulgare, collected in the same station and in th…

Efficacy of spot form of net blotch suppression in barley from seed, fertiliser and foliar applied fungicides

2022

Abstract Spot form of net blotch (SFNB), caused by Pyrenophora teres f. maculata is a prevalent and damaging foliar disease of barley (Hordeum vulgare). Fungicides are commonly used to manage SFNB infection and reduce production loss in susceptible varieties. This study determined the efficacy of suppression of SFNB and associated grain yield and quality improvements from application of fungicides to seed, fertiliser and/or foliar treatments. Eight field experiments were conducted in south-eastern Australia during 2016–2018. Two experiments compared single applications of different commercially available seed, fertiliser and foliar fungicides. Six experiments evaluated different growth stag…

Survey of the mycobiota of Spanish malting barley and evaluation of the mycotoxin producing potential of species of Alternaria, Aspergillus and Fusar…

2005

The present work deals with the toxigenic mycobiota occurring in Spanish malting barley and the capability for producing mycotoxins by several important toxigenic fungi. One hundred and eighty seven samples of malting barley were gathered from Spanish breweries before processing. One hundred and fifty kernels per sample were surface-sanitized with a 2% sodium hypochlorite solution and incubated on three culture media. The most abundant fungi were species of Alternaria, Aspergillus, Penicillium and Fusarium, which were present in 93%, 82.3%, 57.8% and 27.8% of the samples, respectively. To evaluate their mycotoxin producing potential a number of isolates belonging to each genus, except Penic…
