The gene could be modified to produce improved varieties for growing regions in which
seed permeability can be a handicap, Ma said.
«Gene that controls soybean
seed permeability, calcium content, identified.»
Understanding the mechanism that determines
seed permeability could also give researchers better access to the largely untapped genetic diversity of wild soybeans to enrich cultivated varieties, whose lack of genetic richness has curbed improvements in yields.
Millennia ago, farmers in Asia recognized the value of
seed permeability and artificially selected the trait to produce the predecessors of modern cultivated soybean varieties, Ma said.
Not exact matches
But the genetic factors underpinning
seed coat
permeability remained a mystery until Ma and his team used a map - based cloning approach to hone in on GmHs1 - 1 as the gene responsible for hard seededness.
The team found that a mutation in a single pair of nucleotides in the gene causes
seed coat
permeability — that is, a change in one pair out of the approximately 1 billion base pairs that make up the soybean genome.
Vibrational + Provides shelf stable essential fatty acids (EFAs), in the form of flax and chia
seeds, that serve to increase cell wall
permeability so that our cells can both absorb nutrients and release waste / toxins more efficiently.
How about saponin content in some beans and
seeds somehow causing intestinal
permeability?
The closest I've found to a human clinical trial of beans on intestinal
permeability is this study, which found a Chinese medicinal gruel of Job's tears, oat, buckwheat, white bean, yellow corn, red bean, soybean, yam, big jujube, peanut, lotus
seed, and wolfberry changed gut microbiota, improved gut
permeability, lowered endotoxemia, and improved inflammation markers.
