BSCTV-induced disease symptoms in <i>Arabidopsis</i>.

<p>BSCTV infection was accomplished by agroinoculation of the center of rosette leaves of 4-week old plants by pinpricking. (A) Mock-inoculated <i>Arabidopsis</i> developed normal flowers and siliques on the shoot tips. (B) Typical disease symptoms such as curling of shoot tips, siliques, and cauline leaves on BSCTV-infected inflorescences. Anthocyanin accumulated on stunted axillary buds or shoots with callus-like structures. (C) Stunted and curled inflorescence stems on a whole BSCTV-infected plant. (D) Magnified shoot tips with curved, swollen and callus-like structures.
