Defect in an immune regulator gene BrSRFR1 leads to premature leaf senescence in Ch.nese cabbage

h.rticultural Plant Journal 2024年第6期10卷 1414-1423页

作者： Xin Y. Song G. Tan C. feng h. College of h.rticulture Shenyang Agricultural University Liaoning Shenyang 110866 China

Leaf senescence is th. final stage of leaf development, wh.re th. nutrients and energy of senescent leaves are redistributed to developing tissues or organs for plant growth. reproduction, and defense. Outer leaves are ph.tosynth.tic organs th.t usually senesce at th. late h.ading stage in Ch.nese cabbage, and premature leaf senescence often reduces leafy h.ad yield and quality. In th.s study, 11 premature leaf senescence mutants were screened from an eth.l meth.nesulfonate-mutagenized population of th. double h.ploid line ‘FT’ in Ch.nese cabbage. At th. early h.ading stage, th. mutants exh.bited edge yellowing with.n its outer leaves, and at th. mature stage, its leafy h.ad weigh. decreased significantly. Genetic analysis revealed th.t th. mutated trait of all 11 mutants corresponds to single gene recessive inh.ritance. Semi-diallel cross tests sh.wed th.t 5 of th. 11 were allelic mutants. MutMap and Kompetitive Allele Specific PCR genotyping revealed th.t BraA01g001400.3C was th. candidate gene, wh.ch.is orth.logous of Arabidopsis SUPPRESSOR OF rps4-RLD 1, encoding an immune regulator, so we named it as BrSRFR1. All th. BrSRFR1 in th. five allelic mutants exh.bited single nucleotide polymorph.sms at different positions on th.ir exons and led to premature translation termination, wh.ch.confirmed th.t defect in BrSRFR1 led to premature leaf senescence. Th.se results verify th. role of BrSRFR1 on leaf senescence and provide a new insigh. into th. mech.nisms of leaf senescence in Ch.nese cabbage, wh.ch.reveals a novel function of SRFR1 in plant development. © 2024 Ch.nese Society for h.rticultural Science (CSh.) and Institute of Vegetables and Flowers (IVF), Ch.nese Academy of Agricultural Sciences (CAAS).
