Different combinations of mutations can affect the size of tomatoes unpredictably, as shown by these different combinations.

Plant mutation research aimed at predictability

Science Notes: More accurate breeding could result from more predictable mutations

Both people and tomatoes come in different shapes and sizes.  That is because every individual has a unique set of genetic variations, mutations, that affect how genes act and function. Added together, millions of small genetic variations make it hard to predict how a particular mutation will impact any individual.  Cold Spring Harbor Laboratory (CSHL) […] Read more

Stem cell growth, required for kernel development, is controlled in corn by a set of genes called CLEs. Using CRISPR genome editing, CSHL researchers found they could change kernel yield and ear size by fine-tuning the activity of one of the CLE genes, ZmCLE7.

Tweaking corn kernels with CRISPR

Science Notes: In some of the first work of its kind, researchers modified corn kernel numbers using CRISPR

Corn has changed over thousands of years from weedy plants that make ears with less than a dozen kernels to the cobs packed with hundreds of juicy kernels that we see on farms today.  Powerful DNA-editing techniques such as CRISPR can speed up that process.  Cold Spring Harbor Laboratory (CSHL) Professor David Jackson and his […] Read more
