2 Sept 2016 The sum of the parts (similarities between us and plants – TAU Research – What a Plant Knows (Farrar, Straus and Giroux) and Happy Birthday to Easy Weimaraner

Hello, it’s officially Friday or Freitag in German – a special Happy Birthday shout out to my favorite Wiemaraner Easy!


Still awake…the count down to our going to the Distant Worlds Final Fantasy concert is about 5 hrs now!! YEAH!  So excited!

While I was outside a bit ago I noticed an oak leaf that was laying on our bandstand.  After enjoying my music with some dance I picked it up and I noticed as I looked at it next to my hand this leaf had a very similar structure to my hand.  This is something I’ve noticed several times before…the dried leaf even “sparkles” or has a shine like we do in the sunlight.  Something else we have in common with our family the trees!  A poem I’ve shared with you a couple times before came to mind in this train of thought I was having with this leaf.  Of how as a human being I am a sum of all the “parts” that make up this world.  Each part of my physical being seemingly borrowed or copied or shared from another physical being I share this planet with.  We are like mobile, mini-earths!  Individual little “planets” all sharing the one that dreamt of us….we are living manifestations of a great dream.  A great collaborative dream of  faith, joy, hope and love.    Are we like a carefully crafted patchwork “quilt?”   A little piece here, a little piece there….

TAU researcher reveals link between plant and human biology
Published on July 31, 2012 at 2:49 AM · No Comments

Increasingly, scientists are uncovering surprising biological connections between humans and other forms of life. Now a Tel Aviv University researcher has revealed that plant and human biology is much closer than has ever been understood – and the study of these similarities could uncover the biological basis of diseases like cancer as well as other “animal” behaviors.

In his new book What a Plant Knows (Farrar, Straus and Giroux) and his articles in Scientific American, Prof. Daniel Chamovitz, Director of TAU’s Manna Center for Plant Biosciences, says that the discovery of similarities between plants and humans is making an impact in the scientific community. Like humans, Prof. Chamovitz says, plants also have “senses” such as sight, smell, touch, and taste.

Ultimately, he adds, if we share so much of our genetic makeup with plants, we have to reconsider what characterizes us as human.

These findings could prompt scientists to rethink what they know about biology, says Prof. Chamovitz, pointing out that plants serve as an excellent model for experiments on a cellular level. This research is also crucial to food security, he adds, noting that knowledge about plant genetics and how plants sense and respond to their environment is central to ensuring a sufficient food supply for the growing population – one of the main goals of the Manna Center.

Seeing the light

One of the most intriguing discoveries of recent years is that a group of plant genes used to regulate responses to light is also part of the human DNA. These affect responses like the circadian rhythm, the immune system, and cell division.

A plant geneticist, Prof. Chamovitz was researching the way plants react to light when he discovered an group of genes that were responsible for a plant “knowing” whether it was in the light or in the dark. He first believed that these genes were specific to plant life, but was surprised to later identify the same group of genes in humans and animals.

“The same group of proteins that plants use to decide if they are in the light or dark is also used by animals and humans,” Prof. Chamovitz says. “For example, these proteins control two seemingly separate processes. First, they control the circadian rhythm, the biological clock that helps our bodies keep a 24 hour schedule. Second, they control the cell cycle – which means we can learn more about mutations in these genes that lead to cancer.” In experiments with fruit flies who had a mutated version of one of these genes, Prof. Chamovitz and his fellow researchers observed that the flies not only developed a fly form of leukemia, but also that their circadian rhythm was disrupted, leading to a condition somewhat like permanent jet-lag.

Plants use light as a behavioral signal, letting them know when to open their leaves to gather necessary nutrients. This response to light can be viewed as a rudimentary form of sight, contends Prof. Chamovitz, noting that the plants “see” light signals, including color, direction, and intensity, then integrate this information and decide on a response. And plants do all this without the benefit of a nervous system.

And that’s not the limit of plant “senses.” Plants also demonstrate smell – a ripe fruit releases a “ripening pheromone” in the air, which is detected by unripe fruit and signals them to follow suit – as well as the ability to feel and taste. To some degree, plants also have different forms of “memory,” allowing them to encode, store, and retrieve information.

Just like us

Beyond the genes that regulate responses to light, plants and humans share a bevy of other proteins and genes – for example, the genes that cause cystic fibrosis and breast cancer. Plants might not come down with these diseases, but the biological basis is the same, says Prof. Chamovitz. Because of this, plants are an excellent first stop when looking for a biological model, and could replace or at least enhance animal models for human disease in some types of research.

My feeling about trees is that everything I need to know about life, death and rebirth I can see in the life cycle of a tree.  The tree is also a dimension, a mini-earth unto each one.  Just look!

  1. thanks for my birthday greeting :o) I never noticed that leaves and hands have such a lot in common… I will try it too with a leaf and my hands, maybe I will find some similarities too :O)

    • Your welcome and yes, for those with paws comparisons to leaves would have to start with the pads but trees get “hair” too to it probably doesn’t matter does it? We are all part of the same Tree of Life. Love and hugs!
