Tal Barkai, Oran Yakubovsky, Yael Korem Kohanim, Keren Bahar Halpern, Sapir Shir , et al. · 2025

Single-cell atlases provide valuable insights into gene expression states but lack information on cellular dynamics. Understanding cell turnover rates—the time between a cell’s birth and death—can shed light on stemness potential and susce…

Identification of core, conditional and crosstalk components of tomato heat stress response using integrative transcriptomics and orthology Open

Dennis Psaroudakis, Abul Khayer, Leke Victor Aiyesa, Nick Bergau, Alain Tissier , et al. · 2024

Modulating auxin response stabilizes tomato fruit set Open

Alon Israeli, Ramona Schubert, Nave Man, Naama Teboul, Juan Carlos Serrani Yarce , et al. · 2023

Fruit formation depends on successful fertilization and is highly sensitive to weather fluctuations that affect pollination. Auxin promotes fruit initiation and growth following fertilization. Class A auxin response factors (Class A ARFs) …

TOR coordinates Cytokinin and Gibberellin signals mediating development and defense Open

Iftah Marash, Rupali Gupta, Gautam Anand, Meirav Leibman‐Markus, Naomi Lindner , et al. · 2022

Plants constantly perceive and process environmental signals and balance between the energetic demands of growth and defense. Growth arrest upon pathogen attack was previously suggested to result from a redirection of the plants’ metabolic…

The VIL gene CRAWLING ELEPHANT controls maturation and differentiation in tomato via polycomb silencing Open

Ido Shwartz, Chen Yahav, Neta Kovetz, Matan Levy, Alon Israeli , et al. · 2022

VERNALIZATION INSENSITIVE 3-LIKE (VIL) proteins are PHD-finger proteins that recruit the repressor complex Polycomb Repressive Complex 2 (PRC2) to the promoters of target genes. Most known VIL targets are flowering repressor genes. Here, w…

Leaflet initiation and blade expansion are separable in compound leaf development Open

Fei Du, Yajin Mo, Alon Israeli, Qingqing Wang, Tamar Yifhar , et al. · 2020

SUMMARY Compound leaves are composed of multiple separate blade units termed leaflets. In tomato ( Solanum lycopersicum ) compound leaves, auxin promotes both leaflet initiation and blade expansion. However, it is unclear how these two dev…

Collaboration of multiple pathways in making a compound leaf Open

Alon Israeli, Ori Ben‐Herzel, Yogev Burko, Ido Shwartz, Hadas Ben‐Gera , et al. · 2020

Summary The variability in leaf form in nature is immense. Leaf patterning occurs by differential growth that occurs during a limited window of morphogenetic activity at the leaf marginal meristem. While many regulators have been implicate…

Deep conservation of cis-element variants regulating plant hormonal responses Open

Michal Lieberman‐Lazarovich, Chen Yahav, Alon Israeli, Idan Efroni · 2019

Phytohormones regulate many aspects of plant life by activating transcription factors (TFs) that bind sequence-specific response elements (REs) in regulatory regions of target genes. Despite their short length, REs are degenerate, with a c…
