Abstract Key message Intensive public sector breeding efforts and public-private partnerships have led to the increase in genetic gains, deployment of elite climate-resilient maize cultivars for stress-prone environments tropics. Maize ( Zea mays L.) plays a critical role ensuring food nutritional security, livelihoods millions resource-constrained smallholders. However, yields tropical rainfed are now increasingly vulnerable various climate-induced stresses, especially drought, heat, waterlogging, salinity, cold, diseases, insect pests, which often come combinations severely impact crops. The International Wheat Improvement Center (CIMMYT), partnership with several private institutions, has been intensively engaged over last four decades germplasm tolerance key abiotic biotic using an extensive managed stress screening network on-farm testing system. This successful development array stress-tolerant across sub-Saharan Africa, Asia, Latin America. Further increasing gains programs demands judicious integration doubled haploidy, high-throughput precise phenotyping, genomics-assisted breeding, data management, more effective decision support tools. Multi-institutional efforts, public–private alliances, ensure that improved varieties effectively reach climate-vulnerable farming communities tropics, including accelerated replacement old/obsolete varieties.

Abstract Research in the past decade has demonstrated that a single reference genome is not representative of species’ diversity. MaizeGDB introduces pan-genomic approach to hosting genomic data, leveraging large number diverse maize genomes and their associated datasets quickly efficiently connect genomes, gene models, expression, epigenome, sequence variation, structural transposable elements, diversity data across so researchers can easily track functional differences locus its orthologs maize. We believe our framework unique provides template for any database poised host large-scale data.

Genome editing is a relevant, versatile, and preferred tool for crop improvement, as well functional genomics. In this review, we summarize the advances in gene-editing techniques, such zinc-finger nucleases (ZFNs), transcription activator-like (TAL) effector (TALENs), clustered regularly interspaced short palindromic repeats (CRISPR) associated with Cas9 Cpf1 proteins. These tools support great opportunities future development of plant science rapid remodeling crops. Furthermore, discuss brief history each provide their comparison different applications.

Abstract Maize productivity is threatened by global climate change. Climate change scenarios suggest that north‐western (NW) Europe will get warmer and drier during the main crop‐growing period. In general, more northerly regions benefit, whereas southerly suffer suboptimal rain‐fed farming conditions. these latter in particular, resulting probable lower realized on‐farm maize grain biomass yields must be safeguarded. Breeding for resistance against already existing emerging diseases insect pests one component to achieve yield stability across years. Durable multiple‐disease become especially crucial. Herein, we focus on disease breeding approaches maize, related northern corn leaf blight Fusarium ear rots, although virus bacterial important as well. Continuous adjustments of strategies required. Insect pest improved considerably, a world insects thrive, probably causing detrimental direct (feeding, sucking, etc.) indirect (vectors pathogens, feeding wounds creating gateways many passive transport inoculum plants) effects. Four case studies are prevalent NW or may expected near future covered this review. cultivars need combine both durable multiple‐insect resistance, implementation different effective resources programmes challenging, particularly if trade‐offs among goals appear.
