Abstract The northern corn leaf blight (NCLB) is one of the most important diseases affecting leaves. Resistance and tolerance mechanisms play crucial roles in helping plants protect themselves from pathogen attacks. landraces Far West Santa Catarina (FWSC), along with recent studies, have shown significant genetic variability for various traits. However, presence qualitatively resistant genes has not been confirmed. To address this gap, two experiments were conducted a randomized block design four replications during 2019/2020 season. One experiment involved inoculation concentration 2x103 spores mL− 1, without chemical control, while other was inoculated, NCLB controlled difenoconazole-based fungicide. Evaluation included lesion type, incubation period, latency severity measured by area under disease progress curve (AUDPC), ear productivity. obtained data subjected to analysis variance, Tukey's mean test applied individual variance analyses variables IP, LP, AACPD, PROD.

Societal Impact Statement Agricultural sustainability depends on the adaptation of crops to their local environment. Smallholder farmers who save seed provide an essential “evosystem” service by growing locally adapted varieties that can recruit biodiversity enhance growth and defense. While professional plant breeding has diverted evolutionary processes away from adaptation, smallholder farmers, particularly those in centers origin for crops, benefit society selecting propagating diverse crop allow perpetuate.

Traditional cereals, recognised for their adaptability, high nutritional value, and unique sensory characteristics, have largely been excluded from global food supply chains. Recent shifts in consumption patterns, particularly urban areas, indicate a growing demand high-quality bread, creating new opportunities farmers interested sustainable production techniques traditional varieties. However, challenges such as seed availability, regulatory constraints, marketing strategies, logistical barriers persist. This study, conducted within the framework of CERTRA project—Development Cereal Value Chains Sustainable Food Portugal—aims to enhance cereal value chain Portugal by identifying key proposing effective development strategies. The research employs mixed-method approach, including documentary research, SWOT analysis based on scientific literature stakeholder insights, case study methodology examining twelve successful European initiatives. findings highlight strengths sovereignty, resilience under low-input farming, market potential through certification short weaknesses lower yields, mechanisation challenges, access restrictions remain critical obstacles.

Salinity, one of the major abiotic stresses in plants, significantly hampers germination, photosynthesis, biomass production, nutrient balance, and yield staple crops. To mitigate impact such stress without compromising quality, sustainable agronomic practices are required. Among these practices, seaweed extracts (SWEs) microbial biostimulants (PGRBs) have emerged as important categories plant (PBs). This research aimed at elucidating effects on growth, yield, status two Greek tomato landraces (‘Tomataki’ ‘Thessaloniki’) following treatments with Ascophyllum nodosum extract ‘Algastar’ PGPB ‘Nitrostim’ formulation. Plants were subjected to bi-weekly applications supplied solutions: 0.5 mM (control) 30 NaCl. The results revealed that different mode(s) action PBs impacted tolerance landraces, since ‘Tomataki’ was benefited only from SWE application while ‘Thessaloniki’ showed significant increase fruit numbers average weight both NaCl root zone. In conclusion, induced by salinity can be mitigated increasing through PBs, a tool for productivity enhancement, which aligns well strategy European Green Deal.

Salt stress is a major abiotic stressor that limits plant growth, development, and agricultural productivity, especially in regions with high soil salinity. With the increasing salinization of soils due to climate change, developing salt-tolerant crops has become essential for ensuring food security. This review consolidates recent advances genetics, transcription factors (TFs), next-generation sequencing (NGS) technologies are pivotal enhancing salt tolerance crops. It highlights critical genes involved ion homeostasis, osmotic adjustment, signaling pathways, which contribute resilience under saline conditions. Additionally, specific TF families, such as DREB, NAC (NAM, ATAF, CUC), WRKY, explored their roles activating salt-responsive gene networks. By leveraging NGS technologies-including genome-wide association studies (GWASs) RNA (RNA-seq)-this provides insights into complex genetic basis tolerance, identifying novel regulatory networks underpin adaptive responses. Emphasizing integration tools, research, NGS, this presents comprehensive framework accelerating development crops, contributing sustainable agriculture saline-prone areas.

One of the consequences intensification is an increase crop uniformity hence a reduction landraces’ resources. Messinia, located Southwest Peloponnese, Greece, characterized by diverse terrain smallholdings. The geomorphological character area farmers’ selections have led to new landraces (local varieties) with unique traits specific adaptations.
