"PHENOTYPIC PLASTICITY of plants is based on the polar auxin transport machinery that is directly linked with plant sensory systems impinging on plant behavior and adaptive responses." (Phenotypic plasticity is regarded by many as the tangible outcome of plant computation). http://journal.frontiersin.org/article/10.3389/fcimb.2013.00044/full View in LinkedIn

FEEDING INFLUENCE. “Current hypotheses state that the evolution of feeding behaviors may have been the driver for the structural modifications of the crocodilian rostrum: The displacement and remodeling of the bones configuring the crocodilian secondary palate, which may initially have occurred reinforce the snout and skull instead of providing a physical bony partition between the oral and nasal cavities.” http://www.wjgnet.com/esps/DownLoadFile.aspx?Type=Digital&SubType=2&DOI=10.5319%2Fwjo.v6.i2.33&FilePath=Pub%5C10.5319%5Cv6%5Ci2%5CWJO-6-33.doc View in LinkedIn

CROCODILE SUMMARY. “Crocodilian evolution has been characterized by the gradual constitution of an akinetic skull and the formation of a secondary nose.” http://www.wjgnet.com/esps/DownLoadFile.aspx?Type=Digital&SubType=2&DOI=10.5319%2Fwjo.v6.i2.33&FilePath=Pub%5C10.5319%5Cv6%5Ci2%5CWJO-6-33.doc View in LinkedIn

CONNECTING TO RESPIRATION. “In the early fully terrestrial tetrapods, a transverse sheet of dermal bones has developed inferior to the braincase specifically in the roof of the mouth posterior to the internal naris and primary palate. This secondary hard palate configuration was probably the precursor in allowing permanent breathing to travel through the primary nose as inspiratory air would travel through a non-collapsible oral cavity before going to the trachea.” http://www.wjgnet.com/esps/DownLoadFile.aspx?Type=Digital&SubType=2&DOI=10.5319%2Fwjo.v6.i2.33&FilePath=Pub%5C10.5319%5Cv6%5Ci2%5CWJO-6-33.doc View in LinkedIn

FRAGMENT FROM NATURE continues from last weekend and concludes this weekend on the evolutionary origin of the human nose. It is a case study of a dual function organ, respiration and olfaction combined, and how those two functions came together in surprising ways. Just as the functions of breathing, swallowing, and vocalization came together in a single organ — an unlikely combination at best — these cases illustrate that nature and logic are remotely related.

ANCIENT SHARED SIGNAL. "The plant hormone auxin is an important player for interkingdom communication in the rhizosphere. It is not only a crucial signaling molecule for plant biology, but it is also an ancient signaling molecule used by microorganisms." http://journal.frontiersin.org/article/10.3389/fcimb.2013.00044/full View in LinkedIn

"ROOT TIPS are most active with respect to feeding the rhizosphere, with the largest carbon depositions situated around the first 3 mm of maize roots, which include—besides the root cap—the meristem and the transition zone." http://journal.frontiersin.org/article/10.3389/fcimb.2013.00044/full View in LinkedIn

RHIZOSPHERE. "This unique ecosphere represents one of the most energy-rich habitats on Earth. Plants invest about 20% of their photosynthetically fixed carbon into feeding the rhizosphere microbiome and other organisms living in this unique ecosphere." http://journal.frontiersin.org/article/10.3389/fcimb.2013.00044/full View in LinkedIn

SHIFT TO LAND. "It is assumed that land plants evolved from algae, but the initial invasion of dry and rocky land was probably possible only through an alliance of ancient algae and fungi. Only alliances of fungi, algae, and bacteria could allow for the shift from ocean to hostile land environments, where progressive transformation led to emergence of fertile life-supporting land." http://journal.frontiersin.org/article/10.3389/fcimb.2013.00044/full View in LinkedIn
