Use of Blue-Green Fluorescence and Thermal Imaging in the Early Detection of Sunflower Infection by the Root Parasitic Weed Orobanche cumana Wallr. http://hdl.handle.net/10261/152640, The world production of main oil crops increases steadily. This growth is caused by population growth, increased use of oil crops in bio-fuel production, and increased use of vegetable oils in human nutrition. Oil crops are grown worldwide under varied agro-climatic conditions and are vital commodities in the trade and commerce of many economies. From the perspective of the sown areas, the oil crops are the second most important in the world, preceded by cereals. Oil crops include both annual and perennial plants whose seeds, fruits or mesocarp, and nuts are valued mainly for the edible or industrial oils that are extracted from them. There are about 40 different oil crops whose oil can be consumed but only soybean, sunflower and rapeseed are significant in the total world trade. Sustainable oil crops systems must harmonize productivity with conservation of natural resources and environmental protection. The research conducted must be consequently oriented towards the improvement of productivity and, at the same time, the investigation in options for sustainable exploitation of resources as well as minimized effects on the environment. Plant breeding has played an essential role in supporting oil crops expansion: breeding for higher yield and oil content allowed for an increase in oil production per unit area, whereas breeding for better oil quality has improved both the human health value as well as the suitability of oils in industrial applications. This has been supplemented with the advanced scientific production technologies which have resulted in high levels of per unit productivity, particularly in countries with high standards of agricultural production. Research in agronomy of oil crops must be committed to sustainability through the rational use and conservation of water and soil resources. Current resource management is facilitated by the application of new technologies (models, remote sensing, control/automation, instrumentation. Oil crop production efficiency must be increased through the integrated management of invertebrate pests, pathogens, and weeds. Novel options for the control of biotic stresses also play a major role. Research is therefore focused to the development of innovative and environmentally friendly management strategies and aims at ensuring both the efficiency of the oil crops systems and the quality of oil production. The aim of the Research Topic “Advances in Oil Crops Research – Classical and New Approaches to Achieve Sustainable Productivity” is to compile the latest research dealing with different aspects of oil crops, including the breeding and selection of varieties for high yield or specific traits, biodiversity, sustainable cultivation, food and feed uses, nutritional value or health benefits, pests, diseases, weeds, integrated pest management, soil fertility and crop nutrition, soil tillage and conservation, crop ecology and physiology, and water management. The goal of this Research Topic is not only to present the most advanced research dealing with oil crops, but also to attract valuable research articles, reviews and methods in order to offer an outstanding overview of these crops essential to worldwide food supply. Important Note: All contributions to this Research Topic must be within the scope of the section and journal to which they are submitted, as defined in their mission statements. Frontiers reserves the right to guide an out-of-scope manuscript to a more suitable section or journal at any stage of peer review.

The relationship between early root and shoot formation at the beginning of the vegetation period and cutting survival on sandy and loamy fluvisol for 14 genotypes of black poplars was analyzed. Considerable cutting mortality was observed only within the first 80 days since planting. Intensive root formation in the first 20 days since the planting and vigorous shoot growth and development in subsequent 20 days was observed in easy-to-root genotypes. Coefficients of correlation revealed close relationship between early root and shoot growth and development and cutting survival of tested genotypes. The obtained results could be used in the breeding process, as well as for the design of cultivar-adjusted nursery and plantation establishment technology. Tested shoot characteristics, were found to be especially interesting since they could be measured rapidly, by non-destructive means.

Trabajo presentado en el Third Internacional Symposium on broomrape (Orobanche spp.) in Sunflower, celebrado en Córdoba (España) del 3 al 6 de junio de 2014., The factors associated with the distribution of parasitic weed Orobanche cumana Wallr. (Broomrape), limiting sunflower production in Europe and the surrounding continents of Asia and Africa, have not been adequately investigated. The goals of this study were to broaden the understanding of environmental factors associated with broomrape’ distribution in Europe, and to predict suitable habitats based on environmental factors which would be vulnerable to invasion and establishment of broomrape in North and South America. A robust agroecological database included 35 quantitative parameters associated with trials conducted by ten public research organizations from five continents. The database consisted of 117 sites (habitats), Europe (79), Africa (3), Asia (6), and Americas (29), equally distributed between invaded and non- invaded habitats. Environmental parameters analyzed using an ANOVA and PCA showed that all sunflower areas from Europe were vulnerable to broomrape attack. The parasitic weed develops in soil and climate environmental conditions similar to non-invaded areas. Its expansion to nearby areas of the Africa and Asia continents seems to indicate a broadening of the environmental conditions to which the parasitic weed can tolerate. Habitat conditions of sunflower crop areas in South America showed more similarity to invaded habitats than North America. The absence of the ability to predict actual broomrape distribution based on environmental factors enforces the need to use cultural practices of crop rotation and genetic resistance in infected areas. Strict phytosanitary controls need to be enforced to prevent the inadvertent introduction into non-infected areas and its spread in infected areas., This work is a part of the projects TR31025, Ministry of Education, Science and Technological Development of Republic of Serbia, and PNCyO 112745, Instituto Nacional de Tecnología Agropecuaria, Argentina.

20 p.-3 fig., Although epigenetic modifications have been intensely investigated over the last decade due to their role in crop adaptation to rapid climate change, it is unclear which epigenetic changes are heritable and therefore transmitted to their progeny. The identification of epigenetic marks that are transmitted to the next generations is of primary importance for their use in breeding and for the development of new cultivars with a broad-spectrum of tolerance/resistance to abiotic and biotic stresses. In this review, we discuss general aspects of plant responses to environmental stresses and provide an overview of recent findings on the role of transgenerational epigenetic modifications in crops. In addition, we take the opportunity to describe the aims of EPI-CATCH, an international COST action consortium composed by researchers from 28 countries. The aim of this COST action launched in 2020 is: (1) to define standardized pipelines and methods used in the study of epigenetic mechanisms in plants, (2) update, share, and exchange findings in epigenetic responses to environmental stresses in plants, (3) develop new concepts and frontiers in plant epigenetics and epigenomics, (4) enhance dissemination, communication, and transfer of knowledge in plant epigenetics and epigenomics, This finalization of the review was funded by COST Action CA19125—EPIgenetic mechanisms of Crop Adaptation to Climate cHange.
