Cytochrome c and the transcription factor ABI4 establish a molecular link between mitochondria and ABA‐dependent seed germination

Sofía Racca, Diana E. Gras, M. Victoria Canal, Lucía V. Ferrero, more

During germination, seed reserves are mobilised to sustain the metabolic and energetic demands of plant growth. Mitochondrial respiration is presumably required to drive germination in several species, but only recently its role in this process has begun to be elucidated. Using Arabidopsis thaliana lines with changes in the levels of the respiratory chain component cytochrome c (CYTc), we investigated...

Reproductive biology and pollinators in two enantiostylous Qualea species (Vochysiaceae) in the Brazilian Cerrado

J. M. Morais, H. N. Consolaro, L. L. Bergamini, V. Ferrero, more

Plant Biology > 22 > 5 > 872 - 880

Enantiostyly is a floral polymorphism in which two floral forms in the same species differ in deflection of the stigma to right or left position. In monomorphic enantiostylous plants, flowers of the two morphs occur within the same individual, usually in the same proportion. In self‐compatible species the function of monomorphic enantiostyly is proposed to increase outcrossing rates and offer a...

Symmetric 10 Gbps PON Operating With a Single Laser Over 31 dB of ODN Loss

S. Straullu, G. Franco, S. Abrate, F. Forghieri, more

IEEE Photonics Technology Letters > 2017 > 29 > 12 > 956 - 959

We propose a fully bidirectional and symmetrical 10 Gb/s on–off keying Passive Optical Network (PON) solution, using the same wavelength in both upstream and downstream directions. Thanks to the remodulation performed by the optical network unit, it is able to transport 20 Gb/s per wavelength using only one optical source for the full network, regardless of the number of users. The system is based...

2.5 Gbps 2-PSK Ultra-Dense WDM Homodyne Coherent Detection Using a Sub-Carrier Based Optical Phase-Locked Loop

S. Camatel, V. Ferrero, R. Gaudino, P. Poggiolini

IFIP — The International Federation for Information Processing > Optical Networks and Technologies > Modulation Formats > 357-363

We present an optical phase locked loop based on sub-carrier modulation and designed using commercial optical components. In principle the output of a continuous-wave laser is subcarrier modulated by a common LiNbO3 MachZe-hender driven by an electrical voltage controlled oscillator. The proposed architecture is used as optical receiver for homodyne coherent detection of ultra-dense WDM 2.5 Gbps 2-PSK...

Endonasal mucosal contact points in chronic migraine

V. Ferrero, G. Allais, S. Rolando, T. Pozzo, more

Neurological Sciences > 2014 > 35 > 1 > 83-87

Some anatomo-functional alterations of the nose may be considered as possible causes of headache: deviations of the nasal septum, abnormal turbinates, especially middle or superior, with consequent areas of mucosal contact with the septum. This study was performed on 100 subjects, 27 chronic migraine (CM) sufferers and 73 subjects who never suffered from migraine as control group. In the CM group,...

Sexual reproduction of the pentaploid, short‐styled Oxalis pes‐caprae allows the production of viable offspring

J. Costa, V. Ferrero, J. Loureiro, M. Castro, more

Plant Biology > 16 > 1 > 208 - 214

Reproduction is a key factor for the successful establishment and spread of introduced species. Oxalis pes‐caprae is a tristylous species with a self‐ and morph‐incompatibility sexual system that, in the invaded range of the western Mediterranean Basin, has been found to reproduce asexually because only the pentaploid, short‐styled morph (5x S‐morph) was introduced. The objective of this study was...
