Summary Salinity stress limits plant growth and has a major impact on agricultural productivity. Here, we identify NAC transcription factor SlTAF1 as regulator of salt tolerance in cultivated tomato ( Solanum lycopersicum ). While overexpression improves salinity compared with wild‐type, lowering expression causes stronger salinity‐induced damage. Under stress, shoots knockdown plants accumulate more toxic Na + ions, while overexpressors less accordance an altered the transporter genes SlHKT1;1 SlHKT1;2 . Furthermore, stomatal conductance pore area are increased during but decreased overexpressors. We identified stress‐related factor, abscisic acid metabolism defence‐related potential direct targets SlTAF1, correlating it reactive oxygen species scavenging capacity changes hormonal response. Salinity‐induced tricarboxylic cycle intermediates amino acids pronounced than wild‐type plants, so The osmoprotectant proline accumulates plants. In summary, controls tomato’s response to by combating both osmotic ion toxicity, highlighting this gene promising candidate for future breeding stress‐tolerant crops.

Water deficit (drought stress) massively restricts plant growth and the yield of crops; reducing deleterious effects drought is therefore high agricultural relevance. Drought triggers diverse cellular processes including inhibition photosynthesis, accumulation cell-damaging reactive oxygen species gene expression reprogramming, besides others. Transcription factors (TF) are central regulators transcriptional reprogramming many TF genes affected by drought, members NAC family. Here, we identify factor JUNGBRUNNEN1 (JUB1) as a regulator tolerance in tomato (Solanum lycopersicum). Expression JUB1 (SlJUB1) enhanced various abiotic stresses, drought. Inhibiting SlJUB1 virus-induced silencing drastically lowers concomitant with an increase ion leakage, elevation hydrogen peroxide (H2 O2 ) levels decrease drought-responsive genes. In contrast, overexpression AtJUB1 from Arabidopsis thaliana increases tomato, alongside higher relative leaf water content during reduced H2 levels. was previously shown to stimulate DREB2A, involved responses, DELLA GAI RGL1.
