In a study published June 2 in Cellular and Molecular Life Sciences , Yale research worker investigated a factor very similar in both industrial plant and mammal and look at how it affects behavior in each . Tamas Horvath , the Jean and David W. Wallace Professor of Comparative Medicine and senior author of the study , has been thinking about this possibility for some time . “ Years ago , I started to become interested in this musical theme that every live organism must have some homology , some similarity in how they are or what they do , ” he read .
As he began to study behavior and mitochondria specialized structures within cells that yield energy , this idea kept come back to him . He think that if one could change mitochondrial genes in animals and see what behaviour changed and then try the same affair to standardized genes in plants , it might eventually be possible to well empathise human behavior through the written report of industrial plant . If you take that theme another tone , said Horvath , perhaps it ’s possible to , for object lesson , develop a schizophrenic - like works .
For this sketch , Horvath and his co-worker studied a mitochondrial cistron ( Friendly Mitochondria , or FMT ) found in a minuscule efflorescence plant call Arabidopsis thaliana and a very similar factor ( Clustered mitochondria homolog , or CLUH ) found in mice . Mitochondria regulate important functions like metabolic process and are critical for maintain health . In both plants and humans , dysfunctional mitochondria can bear on development and lead to disease , including neurodegenerative disease like Alzheimer ’s disease , Parkinson ’s disease , Huntington ’s disease , and schizophrenic psychosis in humans . For the study , the investigator compared typical plants , plants without FMT , and plants with hyperactive FMT to better understand the gene ’s purpose . They found that it affect many of import characteristics , include germination , or seminal fluid sprouting , root word length , flowering timing , and leaf development .
They also search at two authoritative plant life behaviors : The first was the salt tension response . Too much salinity can belt down plant , so they ’ve modernize conduct to deflect it . When there ’s extra saltiness in their environment , plants tend to arrest germination , hold up efflorescence , and cut off root growth . The researchers recover that FMT is critical for these salt - forfend demeanor . The second type of flora behaviour they investigated is known as hyponastic demeanor — drift based on circadian rhythms . “ Plants are enormously impact by circadian rhythms because the light is the critical energy source for them , ” said Horvath .
