Olive trees, scientifically categorized as Olea europaea L., hold a prominent position among the cultivated trees of Iran. This plant's resistance to drought, salt, and heat is noteworthy, but its sensitivity to frost is a counterpoint. The olive groves of Golestan Province, located in the northeast of Iran, have sustained substantial damage from multiple periods of frost in the last ten years. This investigation aimed to determine and categorize native Iranian olive varieties, emphasizing their frost tolerance and robust agronomic performance. In light of the rigorous autumn of 2016, a selection of 218 frost-hardy olive trees was made from 150,000 mature olive trees (15-25 years old), to meet this objective. Following the cold stress, in field conditions, the selected trees were re-examined at intervals of 1, 4, and 7 months. For this research, 45 individual trees, exhibiting relatively consistent frost hardiness, were re-evaluated and selected, based on 19 morpho-agronomic traits. The 45 chosen olive trees were genetically profiled employing ten highly discerning microsatellite markers. The subsequent selection process culminated in the identification of five genotypes exhibiting the most cold tolerance amongst the initial 45, which were then transferred to a cold room, maintained at freezing temperatures, for image analysis of cold-induced damage. check details Morpho-agronomic analyses of the 45 cold-tolerant olives (CTOs) yielded no evidence of bark splitting or leaf drop. Almost 40% of the dry weight of fruit from cold-tolerant trees was attributed to oil content, indicating the potential these varieties hold for oil production. In addition, the molecular profiling of 45 analyzed CTOs identified 36 unique molecular signatures, exhibiting greater genetic similarity to Mediterranean olive varieties than to those of Iranian origin. This study highlighted the robust potential of locally sourced olive cultivars, offering a superior alternative to commercial varieties for olive grove cultivation in cold environments. For future breeding strategies to address climate change, this genetic resource could be highly valuable.
The maturation of grapes, in terms of technological and phenolic ripeness, is frequently out of sync in warm areas due to climate change. The consistent quality and color of red wines depend directly upon the level and pattern of phenolic compounds within the wine. An innovative method for delaying grape maturation and harmonizing it with a more suitable season for the synthesis of phenolic compounds is the practice of crop forcing. Severe green pruning is undertaken after the blooming period, focusing on the developing buds intended for the next year's growth. Using this strategy, the buds concurrently created are driven to sprout, thereby initiating a later, deferred cycle. Phenolic composition and color changes in wines resulting from different irrigation regimes (full irrigation [C] and regulated irrigation [RI]) and vine cultivation techniques (conventional non-forcing [NF] and forcing [F]) are the focus of this study. An experimental Tempranillo vineyard in the semi-arid Badajoz region (Spain) was the site of the 2017-2019 trial. Four wines per treatment were meticulously elaborated and stabilized, all in keeping with the classic red wine methods. The alcohol content was consistent across all wines, and malolactic fermentation was not performed on any of them. Anthocyanin profiles were evaluated using HPLC techniques. The analysis also encompassed total polyphenolic content, anthocyanin content, catechin content, the contribution of co-pigmented anthocyanins to color, and a variety of chromatic parameters. The year's impact was considerable and consistent across nearly all evaluated parameters, especially in displaying an overall increasing trend for the majority of F wines. Variations in anthocyanin levels were found between F and C wines, particularly concerning delphinidin, cyanidin, petunidin, and peonidin concentrations. Employing the forcing technique, these outcomes demonstrate an elevation in polyphenolic content, achieved by optimizing synthesis and accumulation of these compounds at more favorable temperatures.
Sugarbeets are a primary source of sugar production in the U.S., accounting for 55-60 percent of the total. A fungal pathogen is the primary cause of Cercospora leaf spot (CLS), a critical disease.
Sugarbeet's leaves are afflicted by this noteworthy foliar disease, a major concern. This study investigated management strategies, focusing on reducing the inoculum derived from leaf tissue, a primary site for pathogen survival between agricultural seasons.
A three-year evaluation of fall and spring treatment applications was undertaken at two study sites. Standard plowing or tilling after harvest was coupled with alternative methods: a propane-fueled heat treatment (either fall pre-harvest or spring pre-planting), and a saflufenacil desiccant application seven days prior to the harvest. Leaf samples, post-fall treatments, underwent evaluation to determine the ramifications.

Heat treatments, in aggregate, yielded CLS reductions similar to those from standard tillage procedures, with the reductions being more evenly distributed throughout the years and locations. These findings propose that heat treating fresh or dormant leaf tissue may be an integrated method replacing tillage for managing CLS issues.
Heat treatments, on average, produced CLS reductions that were comparable to standard tillage methods, showing more consistent decreases across various years and geographical locations. Employing heat treatment on fresh or dormant leaf matter presents a potential integrated tillage alternative for managing CLS, according to these findings.
Contributing to both human nutrition and food security, grain legumes play a significant role as a staple crop for low-income farmers in developing and underdeveloped countries, thus enhancing the services provided by agroecosystems. The global grain legume production is significantly affected by viral diseases, substantial biotic stresses. This review scrutinizes the prospect of employing naturally resistant grain legume genotypes discovered within germplasm banks, landraces, and crop wild relatives, a promising, economically sustainable, and environmentally benign solution for diminishing yield loss. Investigations employing Mendelian and classical genetic principles have deepened our comprehension of critical genetic factors controlling resistance to diverse viral pathogens in grain legumes. Molecular marker technology and genomic resource advancements have opened up new possibilities for identifying genomic regions associated with viral disease resistance in a broad range of grain legumes. Techniques such as QTL mapping, genome-wide association studies, whole-genome resequencing, and pangenome and 'omics' approaches are central to these discoveries. Genomic resources, of a thorough and exhaustive nature, have enabled the faster adoption of genomics-based breeding approaches for developing virus-resistant grain legumes. Advancements in functional genomics, particularly transcriptomics, have, at the same time, provided a better understanding of candidate genes and their participation in the viral disease resistance of legumes. This review explores the progress in genetic engineering techniques, particularly RNA interference, and assesses the feasibility of synthetic biology strategies, such as synthetic promoters and synthetic transcription factors, for achieving viral resistance in grain legume crops. The text also investigates the opportunities and limitations of leading-edge breeding technologies and innovative biotechnological tools (such as genomic selection, rapid generation advancement, and CRISPR/Cas9-based genome editing) for the creation of virus-resistant grain legumes to ensure global food security.
