Chestnut trees are an essential source of both food and timber. However, the severe threats from invasive pests diseases compromise their existence productivity. In Europe, chestnut hybridization programs have been initiated to produce resilient rootstocks in response ink disease. gap identification these hybrid plants is typically based on field observations morphological features remains a challenge. Our study presents marker set for distinguishing between CA90 (Castanea sativa × Castanea crenata), with demonstrated resistance Phytophthora cinnamomi, other varieties using microsatellite (SSR) markers bioinformatics tools. We used 35 samples, including three controls, hybrids sampled within Portugal, aim define profiles this band patterns SSR motifs. selected modified nine distinct primers null allelic 43 already developed simple sequence repeat markers. PCR amplification agarose gel electrophoresis were amplify visualize DNA bands. To confirm genetic variations, 27 amplified bands sequenced by Sanger sequencing. This analysis identified 31 SSRs across 22 SSR-containing sequences, trinucleotide (67.74%) repeats being most common, followed dinucleotide (22.58%), mononucleotide (6.45%), hexanucleotide (3.23%). A total 18 alleles observed loci. The ranged one per locus samples. novel CP4 could only be found hybrids. tool can aid identifying selecting disease-resistant hybrids, thereby contributing production management strategies.

Castanea sativa is a high-value tree species whose stands have faced significant threats over the past century. The occurrence of one such threat, Chestnut Red Stain—a heartwood discoloration caused by fungus Fistulina hepatica—has recently increased. This disease devalues timber up to 70% due rejection stained wood industry. study aimed evaluate effects three management strategies on F. hepatica in chestnut coppice stands. Additionally, co-occurrence and Cryphonectria parasitica, both highly prevalent area, was assessed. In 2013, different silvicultural treatments were applied five plots. Seven years later, stand characteristics measured, incidence evaluated using molecular tools. Data modeling revealed that quadratic mean diameter before interventions related hepatica. Our results suggest thinning at earlier stages may be more critical than type or intensity reducing mid-term. finding provides forest managers with new guidance improve prevent damage.

Chestnuts with high economic and socio-cultural value (Castanea sativa Mill.) must determine forests' spatial climatic characteristics to improve them, increase fruit yield, effectively combat diseases pests. This study aimed the attributes of pure chestnut forests spreading within borders Zonguldak Forestry Regional Directorate. A total six criteria were used for analyses: precipitation (mm/year), annual mean temperature (C°), wind speed (m/s), altitude (m), slope (%), aspect (°). Climate values calculated as maximum, minimum, average values, respectively; 1 619.25, 866.95, 024.07 mm/year 13, 6 11.76 C° 6.62, 0.22 2.46 m/s (m/s).

Abstract Taxus cuspidata is a well-known gymnosperm with great ornamental and medicinal value. The study aims to reveal the metabolic differences between wild cultivated species of T. , analyze genetic ecological factors behind these differences. This conducted comparative metabolomics analysis based on LC-MS/MS technology. results showed: (1) A total 7030 metabolites were identified, primarily including flavonoids, organic acids, phenolic amino acids their derivatives, lipids, alkaloids, among others; (2) 2381 differential confirmed: 949 higher in 1432 species, which suggesting have more advantageous metabolites.

Castanea sativa Miller, a high-valuable crop for Mediterranean countries, is facing frequent and prolonged periods of heat drought, severely affecting chestnut production. Aiming to tackle this problem, study unraveled the influence mycorrhizal association with fungi Paxillus involutus (Batsch) on young plants' responses combined (42 °C; 4 h/day) drought (no irrigation until soil moisture reached 25%) over 21 days stress exposure. Heat had no harmful effects growth, photosynthesis, nor induced oxidative in either (MR) or non-mycorrhizal (NMR) plants.

The chestnut is a widely appreciated fruit in Europe, Asia, and North America, playing significant role the diets of people these regions. Due to its high nutritional value diverse health benefits, chestnuts have been gaining considerable research attention. aim was comprehensive literature review on benefits sustainable valorization their by-products. Following methodology, all relevant collected reviewed. Based reviewed data, chemical composition holds great importance, especially food industry, where understanding properties can enhance product development. Furthermore, processing generates substantial amount waste, including shells leaves, which are rich bioactive compounds with antioxidant properties. Valorizing by-products presents opportunities for application across various industries, leading increased profits, reduced environmental pollution, enhanced sustainability. This aims provide insights into explore potential alternative applications materials industry. Such will possibly positively affect producers’ income line circular economy strategy.
