My research team studies the genes that determine when and where, and thus how many, flowers are produced on plants. Flowers form on branches called inflorescences, which originate from stem cells. By studying the genes that control how stem cells become inflorescences, we are able to manipulate flower production to improve crop yields.
Zachary Lippman’s research focuses on the process of flowering and flower production in plants, which are major contributors to reproductive success and crop yield. Specifically, Lippman’s research program integrates development, genetics, genomics, and gene editing to explore the mechanisms that determine how plant stem cells become shoots and flowers. The lab takes advantage of extensive natural and mutant variation in inflorescence production and architecture in tomato and related nightshade species (e.g. potato, pepper, groundcherry) to explore how differences in these processes explain the remarkable diversity in the architectures of flower-bearing shoots (inflorescences) observed in nature and agriculture. Recent discoveries on the genes and networks underlying this diversity have led to broader questions on the significance of genomic structural variation, gene redundancy, and epistasis in development, domestication, and breeding. Based on our fundamental discoveries, Lippman is developing and applying innovative concepts and tools for crop improvement.
The year of CRISPR
December 26, 2018
It’s hard to have missed the acronym CRISPR this year! Headlines in the news have heralded game changing possibilities in biomedicine. Controversy and debate continue to sizzle worldwide among scientists and policymakers over the ethical implications of gene editing in humans. At Cold Spring Harbor Laboratory (CSHL), though, CRISPR isn’t just about headlines. It is...
CRISPR could bring groundcherries to market
October 1, 2018
Cold Spring Harbor, NY — Most people have never tasted a groundcherry; the small, sweet relative of the tomato that plant biologist Zachary Lippman describes as “tropically intoxicating.” That’s because the groundcherry plant, with its long, straggly branches and sporadically ripening fruit, is unsuitable for large-scale agriculture. For now, the treat is reserved for people...
A science writer’s quest to understand heredity
May 30, 2018
LabDish Blog At this very moment, there is more Neanderthal DNA on Earth than there was when Neanderthals were alive. Bits of their DNA, inherited tens of thousands of years ago, persist in many of our genomes today. This astounding legacy is one of many revelations that renowned science writer Carl Zimmer uses to burst...
Prof. Zachary Lippman named Blavatnik Award finalist

Cold Spring Harbor Laboratory (CSHL) Professor and Jacob Goldfield Professor of Genetics Zachary Lippman has been selected as a Finalist in Life Sciences for the 2018 Blavatnik National Awards. The Blavatnik National Awards honor outstanding scientists under the age of 42 in the fields of Life Sciences, Chemistry, and Physical Sciences & Engineering. “This award...
CSHL’s Zachary Lippman named HHMI Investigator
May 23, 2018
Cold Spring Harbor, NY — Zachary Lippman, Ph.D, a Cold Spring Harbor Laboratory (CSHL) Professor and Jacob Goldfield Professor of Genetics, has been selected to be a Howard Hughes Medical Institute (HHMI) Investigator. Dr. Lippman is among 19 other scientists who have just received this distinction. HHMI also announced that it will invest $200 million...
One experiment: Twice the tomatoes
March 22, 2018
Those plump red fruits aren’t the only sweets spots of a tomato plant. The branches have them too. When breeding plants to produce more fruit, “you want to be in a sweet spot” in terms of branching because “plants have to be balanced in their growth,” says Professor Zachary Lippman. That two-pronged plant on the...
Plant geneticists develop a new application of CRISPR to break yield barriers in crops
September 14, 2017
Mutating regulatory regions varies yield traits the way a dimmer switch controls a light bulb Cold Spring Harbor, NY — Scientists at Cold Spring Harbor Laboratory (CSHL) have harnessed the untapped power of genome editing to improve agricultural crops. Using tomato as an example, they have mobilized CRISPR/Cas9 technology to rapidly generate variants of the...

Tomato baby and its family
July 14, 2017
Base Pairs podcast One day, while out tending their experimental tomato fields, Associate Professor Zachary Lippman and his team found something totally bizarre and common at the same time. It was a tomato that looked like a baby, with a head, a body, and arms that seemed to be waving “hello”—and it wasn’t some laboratory-created...
CRISPR vs. climate change
June 15, 2017
Base Pairs podcast Much of the hype around the genome editing tool known as CRISPR focuses on its potential to cure genetic diseases. But our bodies need more than a healthy genome to survive and thrive—they also need food, and that’s where we may see CRISPR’s earliest effects on our lives. “When I think about...
