Cryopreservation of Hazelnut (Corylus avellana L.) Axillary Buds from In Vitro Shoots Using the Droplet Vitrification Method
2021
Cryopreservation by droplet vitrification was applied to hazelnut (Corylus avellana L.). axillary buds of the Italian cultivated variety Tonda Gentile Romana, which were collected from in vitro growing shoots, immersed in ice cooled PVS2 or PVS3 for 60 or 90 min, then transferred to a droplet of vitrification solution, placed on a strip of aluminium foil, and plunged into liquid nitrogen (LN). Additionally, the effect on the recovery of the mother plant after cryopreservation was evaluated, following a cold pre-treatment at 4 °C for 3 months. The highest regrowth percentage (56.7%) was obtained after applying PVS3 for 60 min, while the application of PVS2 for the same amount of time reduced…
Newborn crawling and rooting in response to maternal breast odor
2021
International audience; A growing literature shows that perception and action are already tightly coupled in the newborn. The current study aimed to examine the nature of the coupling between olfactory stimuli from the mother and the newborn's crawling and rooting (exploratory movements of the head). To examine the coupling, the crawling and rooting behavior of 28 2-day-old newborns were studied while they were supported prone on a mobility device shaped like a mini skateboard, the Crawliskate®, their head positioned directly on top of a pad infused with either their mother's breast odor (Maternal) or the odor of water (Control). Video and 3D kinematic analyses of the number and types of li…
Root hydraulic conductivity in three self-rooted and grafted table grape cultivars
2012
<p style="text-align: justify;"><strong>Aim</strong>: Root hydraulic conductivity is one of the main factors that control water flow in the soil-plant system and ultimately affect crop irrigation requirements. This work sets out to estimate root water conductivity for three self-rooted or grafted table grape cultivars.</p><p style="text-align: justify;"><strong>Methods and results</strong>: We evaluated root water conductivity of the cultivars ‘Black Magic’, ‘Matilde’ and ‘Victoria’ grafted onto 1103 Paulsen rootstock or self-rooted. Measurements were performed on two-year-old table grapes grown in pots filled with pumice. Root water conductivity wa…

Carbon stocks in a 50‑year‑oldEucalyptus camaldulensisstand in Sicily, Italy
2015
Eucalyptus stands in semi-arid areas may contribute to enhance carbon (C) stocks in both biomass and soil. However, the limited information available is mainly focused on short-rotation plantations. In this study, the above- and below-ground C pools in five 50-year-old Eucalyptus camaldulensis Dehnh. stands planted on Miocenic evaporitic deposits in Sicily, Italy, with a xeric and thermic pedoclimate, were measured. Above-ground biomass was determined by partitioning and weighing branches, stem and leaves. Below-ground C pools included the determination of litter, root biomass, and soil organic and inorganic C. In terms of the above-ground biomass, the E. camaldulensis stand accumulated on …
Is it possible to understand a book missing a quarter of the letters? Unveiling the belowground species richness of grasslands
2022
Abstract Knowledge of species richness patterns in plant communities is biased toward its hidden belowground part and is derived only from the part visible aboveground. Studies on the relationship of the above- to belowground parts of plant communities suffer from the lack of a consistent and uniform approach to assess their taxonomic composition, particularly in species-rich ecosystems. This study described the proportion between above- and belowground parts of vegetation in three grassland types along with the environmental factors that affect them, using eDNA metabarcoding and an observer survey. The internal transcribed spacer 2 (ITS2) region was used to analyze the total plant richness…
Soil – plant system: a case study of Vitis berlandieri x Vitis rupestris rootstock varieties
2013
Lanthanides are part of rare earth elements. Nowadays studies focused on these elements are increasing to assess the possibility to their use in the traceability to effectively determining the geographical wine origin. In the traceability project we start studying the soil plant system. The aim of the research was to verify if different varieties of rootstock on identical soil have similar lanthanides uptake behavior and if the same rootstock could reproduce different lanthanides distribution for different soil typologies. Three different varieties of rootstock V. berlandieri X V. rupestris (1103 Paulsen, 779 Paulsen and 140 Ruggeri), planted on different soils (carbonatic, clayey and volca…
Study of the role of phosphorylated pathway of serine biosynthesis in arabidopsis development and its connections with nitrogen and carbon metabolism
2016
En plantas se han descrito tres rutas diferentes de para la síntesis de serina: la ruta del glicolato, asociada a la fotorrespiración, y dos rutas independientes de ella, la ruta del glicerato y la ruta fosforilativa de biosíntesis de serina (PPSB). Como la ruta del glicolato es la más importante en términos cuantitativos, el papel de la PPSB ha sido ignorado hasta hace unos años. Esta tesis doctoral aporta nuevas perspectivas sobre la función de la PPSB tanto en el desarrollo como en el metabolismo de Arabidopsis. La PPSB se abastece de 3-fosfoglicerato (3-PGA) como sustrato, el cual puede ser suministrado por la glicolisis plastidial o citosólica. Se asume que la actividad de estas dos ru…
Charged jet cross sections and properties in proton-proton collisions at $\sqrt{s}=7$ TeV
2015
The differential charged jet cross sections, jet fragmentation distributions, and jet shapes are measured in minimum bias proton-proton collisions at centre-of-mass energy $\sqrt{s}=7$ TeV using the ALICE detector at the LHC. Jets are reconstructed from charged particle momenta in the mid-rapidity region using the sequential recombination $k_{\rm T}$ and anti-$k_{\rm T}$ as well as the SISCone jet finding algorithms with several resolution parameters in the range $R=0.2$ to $0.6$. Differential jet production cross sections measured with the three jet finders are in agreement in the transverse momentum ($p_{\rm T}$) interval $20<p_{\rm T}^{\rm jet,ch}<100$ GeV/$c$. They are also consistent w…
