AbstractThe CiteSpace software was used to analyze 3 634 articles on tomato abiotic stress from the Web of Science（WOS）databaseand 55OarticlesfromtheChinaNational Knowledge Infrastructure（CNKI） database （1990—2024） in terms of publication output，contributing institutions，keywords，and burst terms，aiming to explore research hotspots and frontiers inthis field.Theresults showed thatresearch on tomato abiotic stresshas exhibited a stepwise growth trend since 2O04.Northwest A&FUniversityis aleading institution in terms ofpublication output，with 99 articles in WOSand 51 inCNKI.Thematic analysis of keywords revealed thatresearch inthis field mainly focuseson response mechanisms and gene expression under abiotic stresses such as salt stress and temperature stress.The keywords from the CNKI and WOS databases formed12 and13 clusters，respectively，all including 3 major categories： tomato growth performance and yield loss under abiotic stress，tomato molecular mechanisms under abiotic stress，and physiological responses and strategies for coping with tomato abiotic stressTimeline mapping indicated thatresearch in CNKIformedatight clustercentered on melatoninand spermidine after 2O15，while research in WOS focusedon genome-wide identificationand saline-alkali resistance after 2O20，with anemphasis on mining stress-resistant genesatthemolecularlevel.Bursttermanalysis revealedthatresearch hotspotsareshifting fromsalt tolerance to low-temperature stress，and thenewlyemerging keyword“diversity”suggested that future research ill focus on cross-resistance to multiple stresses and the exploration of stress-resistant germplasm resources.The findings studyprovide a reference for in-depth research on tomato stress resistance.
