Maize, a vital crop for human nutrition, livestock, and industrial development, faces increasingly severe climatic conditions that hinder its production capacity along with other strategic crops. Novel treatments based on microorganisms have demonstrated efficiency in enhancing plant development responding to stress. The use of bacteria isolated from seeds is novel approach biotreatment, as recent studies point co-evolution process their presence seeds. This hypothesize pre-adaptation host, which may lead increased efficiency. However, several aspects this remain understudied. In study, we aimed evaluate the potential native maize seed microbiota comparison species mitigate drought For characterized seedborne common productive variety Portugal, it biotreatment two varieties (sensitive resistant drought), selecting strain Pseudomonas fulva MB most promising candidate. Stenotrophomonas maltophilia MS-M1 strain, wild alfalfa previously drought-tolerant enhancer, served non-native control strain. . According data, both enhanced vegetative growth when treated individual strains, well consortium, an increase height 5-7% full medium irrigation, 50-55% not irrigated. trend was also observed weight, by 13-23%, even under no irrigation. addition, positively impacted these treatments, amount grain produced (by weight). drought-sensitive experienced 17% while tolerant 25-40% increase. Under irrigation level, about 15% varieties, 100% 140% each variety, respectively, applied. results suggest P. slightly more efficient treatment, outperformed terms productivity varieties. differences were solid enough all parameters consistently asses such difference. consortium treatment only showed better performance or some traits. These findings support very biotreatments, suggesting than strains remarkable beneficial impact (interspecific), expanding possible kind bioinoculants. Further test are required optimize seed-isolated adapted tailor-made solutions agriculture.

The field of plant breeding has witnessed significant transformations over millennia evolving from rudimentary selection strategies (Breeding 1.0) in ancient times to sophisticated techniques the modern era 4.0) which can identify desirable alleles and engineer contain them all a short amount time, essence, creating 'designer plants'. This evolution aims enhance crop variety improve food security. However, challenges, such as climate change, population growth limited arable land, necessitate more precise efficient methods. Here, artificial intelligence (AI) emerges promising solution. By mimicking human intelligence, AI process vast datasets efficiently, addressing complexities breeding. In this context, facilitates high-throughput phenotyping, gene functional analysis processing extensive environmental data. It revolutionises decision-making by transforming fragmented market information into systematic strategies. review explores historical journey breeding, emphasising shift traditional methods AI-driven approaches. highlights AI's critical role developing climate-resilient pest-resistant crops, ensuring that key staples like maize, wheat, rice, tomato, potato cotton meet global security challenges effectively.

ABSTRACT Maize and wheat are two important cereal crops for the food security of world population. However, constant climate change intensification anthropic activities have intensified emergence stressful environmental in various agricultural production systems around world. Therefore, this study we evaluate chlorophyll content, photosynthesis, transpiration grain yield maize exposed to soil salinity, drought high temperatures determine damage intensity these stressing conditions theoretical multifactorial intensity. Field experiments were conducted during 2022 2023 seasons Yaqui Valley, Sonora, Mexico. The treatments consisted cultivation three environments (soil temperatures) a non‐stressful environment (Control), with four repetitions. tolerance index abiotic stresses, as well stress (salinity, temperatures), morphological traits yield, calculated. results reported that physiological severely affected by conditions. High second factor most limits crops, being more harmful than salinity. has greater negative impact on elite varieties. sum increases both especially crop.

Soil salinization severely affects the quality and yield of maize. As a C4 plant with high efficiency in utilizing light carbon dioxide, maize (Zea mays L.) is one most important crops worldwide. This study aims to investigate pathways mechanisms by which trehalose mediates improvement salt tolerance through combined analysis physiology transcriptomics. The results indicate that foliar application treatment significantly increased biomass antioxidant enzyme activity while reducing H2O2 Na+/K+ ratios both aerial underground parts plant. Additionally, enhanced total secretion organic acids from roots, improving soil microenvironment for growth under stress alleviating Na+ toxicity. Transcriptomic data revealed stress, differentially expressed genes (DEGs) were enriched related photosynthesis, abscisic acid signaling, sugar metabolism, expression levels these pathways, thereby mitigating inhibition caused salinity. elucidates enhancing maize, providing theoretical support its resilience offering innovative strategies wide range saline-alkali land.

Maize is affected by drought and heat, abiotic stress factors that have been encountered more often in recent years various parts of Europe. In the area Turda, Romania, extreme temperatures heat waves combined with an uneven distribution precipitation recorded had unfavorable influence on maize crop. this study, ASI (anthesis-to-silking interval), yield, stability 35 old new hybrids created at Agricultural Research Development Station Turda were studied under conditions. An increase temperature was observed during vegetative growth grain filling, rainfall deficient after flowering. These conditions a negative ASI, and, indirectly, which varied significantly seven experimental years. The five newest (Turda335, Turda2020, Turda380, Sur18/399, HST148) stood out, average yields over 8400 kg ha−1 15–16,000 favorable They generally outperformed mean 29–33%. contrast, achieved up to 22% lower than mean.
