Novel soil-less potting mixes for the mycorrhization of Quercus pubescens Willd. seedlings with Tuber melanosporum Vittad.

Truffle cultivation has quickly grown in Europe and elsewhere as a consequence of the increase in the demand of the market. Thus the optimization of the protocols for the production of elite mycorrhized plants are also needed, keeping in consideration the economic and environmental sustainability. The suitability of two compost-based potting mixes to produce Quercus pubescens Willd.

Molecular markers dataset to assess the genetic diversity of oriental plane trees from historical sites in Lazio (central Italy).

The dataset presented in this article is related to the research paper titled "Dimensional and genetic characterization of the last oriental plane trees of historical sites in Lazio (central Italy)" (Ciaffi et al., 2022). Indeed, the molecular analyses reported in that article consisted in a comparison of Italian veteran plane trees with 12 certified accessions of and their hybrids (4 individuals per species).

DNA integrity and ecophysiological responses of Spanish populations of Ulmus glabra to increasing ozone levels.

Ulmus glabra is a deciduous tree with a wide distribution in the Eurosiberian region. The southernmost populations, in the Mediterranean area, are fragmented in mountain areas which act as a refugium. These small relict populations can act as sentinel of global change, including climate change and impacts of human activities such as air pollution.

Influence of forest stand characteristics on physical, mechanical properties and chemistry of chestnut wood.

Site conditions and forest management affect dendrometric parameters of chestnut (Castanea sativa Mill.) coppices, but there is modest knowledge on the effect of stand dendrometric characters on physical and mechanical wood characteristics. The aim of this study was to verify these relationships in chestnut coppices that were 12-14 years old.

Data set useful for the micropropagation and the assessment of genetic fidelity of veteran trees of L.

The data presented in this article are related to the research article titled "Conservation of veteran trees within historical gardens (COVE): a case study applied to L. in central Italy" (Ciaffi et al., 2018) [1].

Isolation of Mesophyll Protoplasts from Mediterranean Woody Plants for the Study of DNA Integrity under Abiotic Stress.

Abiotic stresses have considerable negative impact on Mediterranean plant ecosystems and better comprehension of the genetic control of response and adaptation of trees to global changes is urgently needed. The single cell gel electrophoresis (SCGE) assay could be considered a good estimator of DNA damage in an individual eukaryotic cell. This method has been mainly employed in animal tissues, because the plant cell wall represents an obstacle for the extraction of nuclei; moreover, in Mediterranean woody species, especially in the sclerophyll plants, this procedure can be quite difficult because of the presence of sclerenchyma and hardened cells.

Comparative study of transcriptional and physiological responses to salinity stress in two contrasting Populus alba L. genotypes.

Soil salinity is an important limiting factor to tree growth and productivity. Populus alba L. is a moderately salt-tolerant species and its natural populations are adapted to contrasting environments, thus providing genetic resources to identify key genes for tolerance to abiotic stress, such as salinity.

Development of a novel set of EST-SSR markers and cross-species amplification in Tamarix africana (Tamaricaceae).

Premise Of The Study: Tamarix plants are resistant to abiotic stresses and have become invasive in North America. Their taxonomy is troublesome, and few molecular makers are available to enable species identification or to track the spread of specific invasive genotypes. Transcriptome sequencing projects offer a potential source for the development of new markers.

Spatial and temporal effects of free-air CO2 enrichment (POPFACE) on leaf growth, cell expansion, and cell production in a closed canopy of poplar.

Leaf expansion in the fast-growing tree, Populus x euramericana was stimulated by elevated [CO(2)] in a closed-canopy forest plantation, exposed using a free air CO(2) enrichment technique enabling long-term experimentation in field conditions. The effects of elevated [CO(2)] over time were characterized and related to the leaf plastochron index (LPI), and showed that leaf expansion was stimulated at very early (LPI, 0-3) and late (LPI, 6-8) stages in development. Early and late effects of elevated [CO(2)] were largely the result of increased cell expansion and increased cell production, respectively.
