Sulfate transporters in the plant’s response to drought and salinity: regulation and possible functions
2014
International audience; Drought and salinity are two frequently combined abiotic stresses that affect plant growth, development, and crop productivity. Sulfate, and molecules derived from this anion such as glutathione, play important roles in the intrinsic responses of plants to such abiotic stresses. Therefore, understanding how plants facing environmental constraints re-equilibrate the flux of sulfate between and within different tissues might uncover perspectives for improving tolerance against abiotic stresses. In this review, we took advantage of genomics and post-genomics resources available in Arabidopsis thaliana and in the model legume species Medicago truncatula to highlight and …
Exploiting 3D Modelling and Life Cycle Assessment to Improve the Sustainability of Pavement Management
2020
Today road agencies worldwide face difficult decisions for construction, maintenance and rehabilitation of their road infrastructure as they try to balance limited budgets. This is further complicated rising environmental concerns over equipment and techniques used for these practices. This has led agencies to consider alternative approaches for smarter and sustainable pavement asset management systems. This paper considers the use of a low-cost 3D image modelling distress identification and classification proposal for data acquisition and analysis. To establish its environmental friendliness, a case study in Palermo, Italy, is considered wherein a Life Cycle Assessment (LCA) exercise is do…
An Epigenetic Alphabet of Crop Adaptation to Climate Change
2022
Crop adaptation to climate change is in a part attributed to epigenetic mechanisms which are related to response to abiotic and biotic stresses. Although recent studies increased our knowledge on the nature of these mechanisms, epigenetics remains under-investigated and still poorly understood in many, especially non-model, plants, Epigenetic modifications are traditionally divided into two main groups, DNA methylation and histone modifications that lead to chromatin remodeling and the regulation of genome functioning. In this review, we outline the most recent and interesting findings on crop epigenetic responses to the environmental cues that are most relevant to climate change. In additi…
Grass Pea
2011
Grass pea (Lathyrus. sativus L.) is an annual legume crop with high protein content and remarkable resistance to extreme environmental conditions, including fl ooding, drought, salinity and low soil fertility, and a signifi cant degree of resistance to biotic stress agents. It is rightly considered one of the most promising sources of calories and protein for the vast and expanding populations of drought-prone and marginal areas of Asia and Africa and as an interesting alternative for cropping systems diversifi cation in marginal lands in Europe, Australia and America. It is a dual purpose crop with great agronomic potential as a grain and forage legume. Nevertheless, as a result of the lit…
Fear of Childbirth, Self-Esteem and Birth Experiences: Pregnancy and Postpartum
2022
This dataset contains all three phases of data collection from the survey study Fear of Childbirth, Birth Experiences, Self-Esteem and Parental Burnout. The data contains answers from participants (n=125) in late pregnancy (30+ weeks in gestation) and postpartum (4-8 weeks after childbirth and 1 year after childbirth). The data is collected in 2020-2021 from four Finnish cities. Participants have completed background information (in pregnancy), fear of childbirth scale (W-DEQ, all three time points), Rosenberg self-esteem scale (all three time points), and Delivery Satisfaction scale (only 4-8 weeks postpartum). In addition, the data contains variables such as depression (BDI), satisfaction…
