Summary: In this study, 28 accessions of Spanish and Tunisian peas were characterized using eight SSR polymorphic markers to assess their genetic diversity. Various methods, including diversity indices, analysis of molecular variance, cluster analysis, and population structure, were applied to evaluate their relationships. The results showed a high level of polymorphism (84.15%) and a significant genetic distance among the accessions. Furthermore, the SSR markers successfully divided the accessions into three major genetic clusters. Therefore, this study demonstrates the usefulness of SSR markers for the management and conservation of pea germplasm in these countries, as well as for future reproduction.

Summary: Metabolic changes in the urea cycle and polyamine metabolism play an important protective role in plants, limiting ammonium toxicity. High ammonium levels lead to the accumulation of pathway intermediates and a decrease in copper amine oxidase activity. Early supplementation of putrescine can prevent ammonium toxicity. Moreover, high ammonium concentrations increase the levels of transcripts encoding related proteins.

Summary: The study aims to understand how peach and nectarine tree varieties respond to winter and spring temperatures and evaluate the effectiveness of different chill and heat accumulation models in predicting bloom dates under various climatic conditions. The researchers analyzed data from 14 cultivars grown in 11 European locations and found significant variations in chill accumulation and rest completion among sites. They also observed that bloom timing is strongly influenced by delayed rest completion and heat accumulation. The Dynamic Model showed better predictions of bloom dates compared to other models. However, further research is needed to improve the reliability of climatic requirements for peach cultivars and provide guidance for adapting peach production to changing climate conditions.

Summary: This study compared the physiological and metabolic responses of a salt-tolerant accession of Vitis sylvestris, Tebaba, from Tunisia, with the widely used 1103 Paulsen rootstock in the Mediterranean. It was found that Tebaba can cope with salinity through robust redox homeostasis, rechanneling metabolic pathways towards antioxidants and compatible osmolytes, and buffering photosynthesis to avoid cell-wall breakdown. It is suggested that introgression of Tebaba into commercial grapevine varieties is preferred over using Tebaba as a rootstock for improving salt tolerance.

Summary: Iron is an essential micronutrient for plants and is usually limited in calcareous soils. This study investigates the effects of the auxin-precursor IAOx on iron deficiency responses in Medicago truncatula plants. The results show that exogenous IAOx promotes lateral roots growth, decreases chlorosis, and delays the decline in pH and increase in FCR activity and flavins in iron-deficient plants. Gene expression levels are consistent with the physiological responses, suggesting that IAOx plays an active role in iron homeostasis.

Summary: In this study, 17 apple accessions were harvested and stored in a cold room for six months to evaluate the differences in biochemical levels between harvest and long-term cold storage. The performance of different accessions was assessed based on fruit quality parameters, antioxidant compounds, sugars, and organic acids. Triploid accessions with russeting showed higher content of bio-active compounds after cold storage, but also experienced cell damages and increased chilling injuries. Spanish accessions and non-Spanish bred cultivars demonstrated suitability for long-term cold storage without chilling injuries. The study highlights the importance of considering native accessions and non-Spanish cultivars in future breeding programs.
