JOINTLESS is a MADS-box gene controlling tomato flower
Aug 24, 2000 · Tomato plants with the jointless mutation 4 fail to develop AZs on their pedicelsand so abscission of flowers or fruit does not occur normally. We identify JOINTLESS as a new MADS-box gene in...
JOINTLESS is a MADS-box gene controlling tomato flower
Aug 24, 2000 · Tomato plants with the jointless mutation fail to develop AZs on their pedicels and so abscission of flowers or fruit does not occur normally. We identify JOINTLESS as a new MADS-box gene in a distinct phylogenetic clade separate from those functioning in floral organs.
JOINTLESS Maintains Inflorescence Meristem Identity in Tomato
Jul 30, 2024 · JOINTLESS (J) was isolated in tomato (Solanum lycopersicum) from mutants lacking a flower pedicel abscission zone (AZ) and encodes a MADS-box protein of the SHORT VEGETATIVE PHASE/AGAMOUS-LIKE 24 subfamily.
Natural and induced loss of function mutations in
Jun 30, 2017 · In tomato, pedicel abscission is an important agronomic factor that controls yield and post-harvest fruit quality. Two non-allelic mutations, jointless (j) and jointless-2 (j-2), controlling...
Interactions between jointless and wild-type tomato tissues …
The jointless mutation of tomato results in the formation of flower pedicels that lack an abscission zone and inflorescence meristems that revert to vegetative growth. We have analyzed periclinal chimeras and mericlinal sectors of jointless and wild-type tissue to determine how cells in different meristem layers (L1, L2, and L3) and their ...

[PDF] JOINTLESS is a MADS-box gene controlling tomato flower ...
Aug 24, 2000 · JointLESS is identified as a new MADS-box gene in a distinct phylogenetic clade separate from those functioning in floral organs and proposed that a deletion in JOINTLESS accounts for the failure of activation of pedicel AZ development in jointless tomato plants.
Molecular Markers to Select for the j-2–mediated Jointless
Feb 1, 2018 · The jointless pedicel trait of tomato conferred by the j-2 gene is widely used in processing markets for stem-free removal of fruit to accommodate mechanized harvest.
One founder mutation enlarged the leaf-like organs on fruits and was selected as fruit size increased dur-ing domestication. The other mutation eliminated the flower abscission zone, providing ‘‘jointless’’ fruit stems that reduced fruit dropping and facilitated me-chanical harvesting.
