Back in 2001, an interesting discovery was made…
“Molecular messengers carry vital instructions from leaves to far-flung stems, say US researchers. Long-distance traffic in grafted tomato stems switches leaves from pointy to round, the team found. This insight into how plant parts talk may help farmers to propagate fruit trees and defend plants against disease..”
Plants that use small channels to link to other cells so things like proteins and sugars which travel from one cell to another until they reach the plant’s super-highway: vessels called phloem. It’s quite remarkable, a plant that is quiet and motionless gives no indication that it can communicate. Compare this to a rock has been exposed to deadly radiation that somehow miraculously get it’s own internet. Evolution has to get one thing from another!
It’s been nine years, what have scientist learned from this discovery? More intriguing things have been reported…Gene regulation play a key role where micro-RNAs are engaged in two-way communication between two cells…
“They also add a new element to the already complex interplay in Arabidopsis roots between two proteins, known as Scarecrow and Short-root, that Benfey’s team had described in earlier work. Those proteins interact and restrain one another to allow the assembly of a waterproofing layer of cells that ultimately enables plants to control precisely how much water and nutrients they take in.
The researchers now show that Short-root moves from cells in the plant’s inner vasculature out into the waterproofing endodermis that surrounds it to activate Scarecrow. Together, those two transcription factors (genes that control other genes) activate microRNAs, known as MIR165a and 166b. Those microRNAs then head back toward the vascular cells, meeting and degrading another transcription factor (called Phabulosa) as well as other regulatory factors along the way.”
For correct patterning of tissues, this internet is vital as Susan Haynes of NIH points out, “This study provides important insight into how cells communicate positional information to orchestrate the complex process of tissue and organ development.”
The evolutionary story assumes miracles happen on cue in order for it’s survival. But think about a single-celled alga which requires a tube to conduct water with a waterproofing layer in order for it to grow a tree. How many one-cell algae would have died off without the tube before an unthinking process would have figured out how to build a tube? It doesn’t make any logical sense that an unthinking process would have such an ability. Only an intelligent designer would have such an ability to create such functions in which we observe.
