Gene editing yields tomatoes that flower and ripen weeks earlier
Summary
TLDRResearchers have discovered a gene crucial for tomato cultivation in northern latitudes, such as the Mediterranean Basin and Canada. This gene, when active, prevents flowering during long days. By suppressing its activity or using CRISPR to mutate it, tomatoes can now be grown in regions with longer daylight hours and shorter growing seasons. This advancement not only accelerates production for market but also expands the geographical range for tomato farming, potentially reaching even the higher latitudes of Canada.

Transcripts
So research in my lab over many years has been focused on identifying
genes that are responsible flowers and plants in particular we work
on tomato and flower production in tomato like many crops is critical for
making fruits and seeds which is of course very important for agriculture
so in our most recent research we've identified a new gene that was critical
for tomato to be cultivated in northern latitudes such as the Mediterranean
Basin where it was first introduced over 500 years ago as well as the northern
latitudes of California and even further north into Canada now it turns out that
this gene is actually responsible for preventing flowering when the days are
very long in order for tomato to now be grown in northern latitudes we had to
have a change in the function or the activity of this gene so that it wasn't
active as much as in the wild in particular what we found is that when
the activity of this gene was suppressed tomato could now be cultivated in
northern latitudes where the day lengths are longer but the growing season is
shorter we then went a step further and asked well if we could completely
eliminate the activity of this gene mutate the gene entirely so that it no
longer functions at all then perhaps we could get even earlier flowering tomato
varieties and we in fact did this using a new and very powerful gene editing
technology known as CRISPR and by using this technology we could pinpoint
mutations directly in the gene and when we generated these mutations we then
created plants that flowered two to three weeks earlier than most varieties
and this may sound like a very subtle change but when you're talking to
farmers you understand that having the ability to generate fruits at an earlier
point in the growing season is not only important for production in order to get
to market faster but also now opens the door to expanding the geographical range
of where the tomato crop can be grown for example and even in higher northern
latitudes of Canada where tomato seasons are very short and so our hope is that
from the discovery of this gene the lab that we can now implement this
in other varieties of tomato and even other crops in order to achieve the same
outcome of early yielding crops.
