Mango magic: unraveling the genetic roots of multiple embryos

A recent study has uncovered the genetic mechanism behind polyembryony in mango—a process where a single seed produces multiple embryos. By identifying the key reproductive wuschel-related protein (MiRWP) gene, researchers have unlocked how this natural cloning process occurs through changes in gene expression. The discovery has potential to transform agricultural practices, offering new methods for cultivating uniform plants and improving crop production efficiency across various fruit species.

New Research Reveals Infertile Spikelets Contribute To Yield In Sorghum And Related Grasses

The researchers used radioactive and stable isotopes of carbon, RNA-seq of metabolically important enzymes, and immunolocalization of Rubisco to show that the sterile spikelet collects carbon from the air and carries out photosynthesis while the awn does not.
