It is likely an arable weed, growing among tomato field crops in the northern KwaZulu Natal province of South Africa. This weed was found to be infected with a strain of Tomato torrado virus (ToTV) (hence the virus-like symptoms).
You can use some android apps on your smart phone for identifying any plant sample such as plantsnap, plantix etc.
Hi Bir, thank you, I will give it a try, however, the symptomatic nature of the image may cause some issues with the identification process, since those are AI applications.
It is difficult to identify a plant without reproductive structures such as flowers and fruits.
Its necessary to provide us with reproductive parts of this weed to facilitate the identification process.
Best regards.
Professor Yehya I took this image during a survey in 2015 and unfortunately, these arable weeds were not flowering at the time. Moreover, the virus discovery was serendipitous. After compiling a very interesting study, the journal wants more details of this newly identified alternative host. I don't have anymore of the infected leaf tissue samples to identify this weed using a genomics approach, therefore, I am hoping that some expert may be able to assist.
it is very difficult to identify the plant only from a leaf (diseases). therefore I am not sure, but the plant can be Velvetleaf, Abutilon theophrasti...
Thank you for the lead Huseyin. You may be right with regards to the genus.
I'm not familiar with South African flora. You are right, the plant may be another species of the same genus as well.
