Development and regulation of pedicel abscission in tomato
To shed unfertilized flowers or ripe fruits, many plant species develop a pedicel abscission zone (AZ), a specialized tissue that develops between the organ and the main body of the plant. Regulation of pedicel abscission is an important agricultural concern because pre-harvest abscission can reduce yields of fruit or grain crops, such as apples, rice, wheat, etc. Tomato has been studied as a m...
متن کاملPedicel breakstrength and cellulase gene expression during tomato flower abscission.
Six cellulase genes were isolated from total RNA of the ethylene-treated tomato (Lycopersicon esculentum Mill.) flower abscission zone by reverse-transcription polymerase chain reaction using degenerate primers to conserved amino acid sequences from known plant cellulases. Four of the gene fragments are homologous to fruit pericarp cellulases. The other two are novel cellulase genes, referred t...
متن کاملA tomato HD-Zip homeobox protein, LeHB-1, plays an important role in floral organogenesis and ripening
Ethylene is required for climacteric fruit ripening. Inhibition of ethylene biosynthesis genes, 1-aminocyclopropane-1-carboxylate (ACC) synthase and ACC oxidase, prevents or delays ripening, but it is not known how these genes are modulated during normal development. LeHB-1, a previously uncharacterized tomato homeobox protein, was shown by gel retardation assay to interact with the promoter of...
متن کاملTomato Transcription Factor SlWUS Plays an Important Role in Tomato Flower and Locule Development
Tomato is a model species for fleshy fruit development. The shapes and sizes of tomato (Solanum lycopersicum L.) are mainly controlled by several loci, including locule number (lc). Two single nucleotide polymorphisms were found downstream of WUSCHEL (SlWUS) in a putative tomato CArG cis-regulatory element. The lc mutation may affect the binding of AGAMOUS(AG), cause the up-regulation of SlWUS ...
متن کاملThe AP2/ERF transcription factor SlERF52 functions in flower pedicel abscission in tomato
In plants, abscission removes senescent, injured, infected, or dispensable organs. Induced by auxin depletion and an ethylene burst, abscission requires pronounced changes in gene expression, including genes for cell separation enzymes and regulators of signal transduction and transcription. However, the understanding of the molecular basis of this regulation remains incomplete. To examine gene...
