A tomato ethylene-insensitive mutant displays altered growth and higher β-carotene levels in fruit

Establishing Ac/Ds Starter Lines for Large-Scale Transposon-Tagged Mutagenesis in Tomato

The paper develops two tomato starter lines with maize transposon elements and transposase to enable large-scale transposon mutagenesis for gene functional validation.

Introgression of a dominant phototropin1 mutant superenhances carotenoids and boosts flavor-related volatiles in genome-edited tomato RIN mutants

This study introduces a tomato cultivar with extended shelf life, improved taste, and flavor by combining genome-edited ripening mutants with a phototropin1 mutant.

Reduced γ-glutamyl hydrolase activity likely contributes to high folate levels in Periyakulam-1 tomato

The paper identifies reduced γ-glutamyl hydrolase activity in PKM-1 tomato as a factor contributing to higher folate levels compared to AV.

Whole-Genome Profiling of Ethyl Methanesulfonate Mutagenesis in Tomato

This study sequenced mutagenized tomato lines to identify mutations, revealing high mutation density and novel insights into EMS mutagenesis patterns and their impact on metabolic pathways.

Seeing the unseen: A trifoliate (MYB117) mutant allele fortifies folate and carotenoids in tomato fruits

A tomato trifoliate allele encoding a truncated MYB117 transcription factor alters cellular homeostasis and fortifies γ-aminobutyric acid, folate, and carotenoids in tomato fruits.

Phytoene synthase 2 in tomato fruits remains functional and contributes to abscisic acid formation

The paper shows that PSY2 contributes to abscisic acid formation in ripening tomato fruits by maintaining a parallel carotenogenesis pathway when PSY1 is absent.

Tomato roots sense horizontal/vertical mechanical impedance and divergently modulate root/shoot metabolome

This study shows tomato roots sense horizontal/vertical mechanical impedance and modulate metabolite profiles differently in roots and shoots.

The new kid on the block: A dominant-negative mutation of phototropin1 enhances carotenoid content in tomato fruits

A dominant-negative mutation in phototropin1 increases carotenoid content and alters metabolite and protein profiles in tomato fruits.

Mutations in Tomato ACC Synthase2 Uncover Its Role in Development beside Fruit Ripening

This study identifies ACS2's role in tomato development beyond fruit ripening by analyzing two contrasting acs2 mutants and their phenotypic and metabolomic differences.

Enhanced polar auxin transport in tomato polycotyledon mutant seems to be related to glutathione levels

The paper investigates the relationship between polar auxin transport and glutathione levels in tomato mutant pct1-2, finding that GSH levels influence PAT and root elongation.

N-1-naphthylphthalamic acid stimulates tomato hypocotyl elongation, elevates ethylene levels and alters metabolic homeostasis

This study shows NPA stimulates tomato hypocotyl elongation by increasing ethylene and altering indole-3-butyric acid and zeatin levels.

NAC-NOR mutations in tomato Penjar accessions attenuate multiple metabolic processes and prolong the fruit shelf life

This study identifies NAC-NOR mutations in tomato Penjar accessions that reduce respiration, alter cuticle composition, and increase ABA and sucrose levels, leading to prolonged fruit shelf life.

MutS-Homolog2 Silencing Generates Tetraploid Meiocytes In Tomato (Solanum lycopersicum)

This study shows that silencing MSH2 in tomato leads to tetraploid meiocytes and abnormal pollen formation due to disrupted meiosis and ploidy stability.
