I place some of R. solani cultured Petriplates under fluorescent tubes and some of the Petri dishes in complete dark. The results were surprising, the color of R. solani under flouresent tubes as whitish while the color of R. solani which were placed in dark as completely dark. What is the reason?
Hello Aqleem,
You observed differences morphology of the same fungi under different environmental conditions, its simply because of phenotypic plasticity of the fungi. It is the ability of a genotype to produce more than one phenotype under different environmental conditions, it may be specific or general.
Hello Aqleem Abbas
You can find different races of Rhizoctonia solani within the same geographic regions. But, in your case, the differences in coloure could be related to the producing of sclerotia or to contamination problem.
Good Luck and Happy New Year

Hi Aqleem
This already happens when you changed the condition like light
Dear Aqleem,
I also had observed the different morphology under different culture media, different temp and varying photoperiod with many fungi.
As said by Dr. Anita, It is due to the phenotypic plasticity in fungi.
Kind regard
Dear , Aqleem Abbas
I agree with Dr. Anita. You can also find the following attached papers .
With my best regards
The metabolism of the R. solani strain changed under light/dark conditions.
Thank you all of the researchers, who contributed to my questions. I will consider your answers for my research.
I also agree, as said by Dr. Anita, It is due to the phenotypic plasticity or variability in fungi due to different environmental condition
I also agree, as said by Dr. Anita, It is due to the phenotypic plasticity or variability in fungi due to different environmental condition and light and temperature play very important role for RS. Even in the case of nutrient scarcity it showed dark color too.
Thank you all of the researchers, who contributed to my questions. I will consider your answers for my research.
