MDMV is the most serious virus of sweet corn. [3] If corn plants are infected with MDMV, ear formation and development are slowed leading to grain yield loss. [4] The damage from MDMV can cause the halting of ear formation and development, ultimately leading to the production of barren ears and direct yield loss. [5]
In the early stages, MLND causes long yellow stripes on leaves. Unlike maize streak virus disease though, the streaks of MLND are wider. As the disease advances, the maize leaves become yellow and dry out from the outside edges towards the midrib. MLND can also cause dwarfing and premature aging of the plants.
The Omicron variant of the virus that causes COVID-19 likely acquired at least one of its mutations by picking up a snippet of genetic material from another virus - possibly one that causes the ...
The Omicron variant of the coronavirus is spreading faster than the Delta variant and is causing infections in people already vaccinated or who have recovered from the COVID-19 disease, the head ...
No evidence has shown that BA.5 will cause more severe illness than previous omicron subvariants. Montefiori said it’s helpful to think of the immune system as having two lines of defense.
This ear of corn has been infected with Mycosarcoma maydis. The fungus infects all parts of the host plant by invading the ovaries of its host. The infection causes the corn kernels to swell up into tumor-like galls, wherein the tissues, texture, and developmental pattern are mushroom-like. The galls grow to 4 to 5 inches in diameter.
In certain corn varieties, kernels can be infected later in the growing season after flowering occurs. Although corn kernels can be a source of inoculuum, seed transmission is quite rare.
