Mosaic virus?

First, the symptoms appeared on the cuttings of the ficus microcarpa. After transplanting, all the plants showed leaf chlorosis, dwarfing, and deformation. A year later, normal leaves grew, but they were small. The same symptoms were also observed on the ficus microcarpa cultivars that were nearby.

Is this mosaic virus?

Welcome to the site! It would help us to know a little more (in general) about where you live - and where you keep these trees. Specifically - lighting, water, soil, and whether you use any fertilizer.

I live in Hokkaido, Japan.

My banyan tree is placed on a windowsill indoors. I am sure that it is receiving enough sunlight, as evidenced by the other ficus plants I have.

I am using inorganic soil. Specifically, I am using a mixture of akadama, kanuma, and pumice in a ratio of 6:2:2.

I do not fertilize it very often.

I don't think it's mosaic virus.
Indoor plants rarely have enough vectors (disease carriers) to get infected.
Unless you smoke cigarettes, TMV is common in tobacco but the transfer from cigarette to living plant is a lengthy process (tobacco is dried, fermented, dried again, cut and burned).

What's more likely is that the cutting process caused some internal processes to use a lot of nitrogen. Combined with rooting hormone response and wound healing, it would explain why we see a spotted pattern.
Mosaic viruses tend to grow along with the plant, with the virus dividing a little slower than the plant itself. So plants can outgrow them! But it would catch up a couple weeks later.
Because it's mostly the old leaves, I believe it's probably a nutrient related deficiency. Especially in thick veined plants with leathery foliage, like ficus, deficiencies can look like viral infections.

Yep, sure looks like chlorosis or one of the similar nutrient issues. One might use a slow release long term fertilizer with micronutrients and apply some soon.

Alternately, foliar feeding with something like dilute Miracle Gro (a liquid fertilizer with micro nutrients) which will give a quick response, and could also be applied to the roots at higher concentrations. Then follow up ever 2-3 weeks.

Love to see some follow up posts!

cheers

I get the virus on my lap top when I watch Japanese Eroticas sometimes

It could be soil ph is too low or high limiting the plants ability to uptake certain nutrients. I have this same problem in a ficus religiosa and I watered in some powdered dolomite lime to help get the ph of the soil back where it needs to be and the chlorosis is starting to go away.

モザイクウイルスではないと思います。
屋内植物が感染するのに十分なベクター (病気の保因者) を持っていることはほとんどありません。
紙巻きタバコを吸わない限り、TMV は紙巻きタバコによく見られますが、紙巻きタバコから生きている植物への移行には長いプロセスが必要です (タバコは乾燥、発酵、再度乾燥、切断、燃焼されます)。

さらに考えられるのは、切断プロセスにより一部の内部プロセスで大量の窒素が使用された可能性です。発根ホルモン反応と創傷治癒を組み合わせると、斑点状のパターンが見られる理由が説明されます。
モザイクウイルスは植物とともに増殖する傾向があり、ウイルスの分裂は植物自体よりも少し遅くなります。したがって、植物はそれらを超えて成長することができます。しかし、数週間後には追いつくでしょう。
ほとんどが古い葉なので、おそらく栄養関連の欠乏症だと思います。特にイチジクのような革のような葉を持つ太い葉脈のある植物では、欠乏はウイルス感染のように見えることがあります。

Thank you for your comment.

Indeed, I pruned the leaves of all the plants that were affected. And the leaves that also showed similar symptoms were also from ginseng cuttings. They were seen a few months later.

New symptoms have appeared, including variegation, a mysterious jelly-like sap, and white fungal-like masses. These symptoms are found on both the trunk and leaves.
The sap has a rubbery feel, like a contact lens. The white fungal-like masses are not like scale insects, but rather like calluses. When touched with a toothpick, the white masses are hard, but the sap can be easily removed, like a contact lens.
It is not clear whether the leaf variegation is a separate symptom from these other symptoms, or whether it is the same. However, the two symptoms are occurring simultaneously.
