D satellite RNA (satRNA) with its helper virus, namely, cucumber mosaic virus, causes systemic necrosis in tomato. The infected plant exhibits a distinct spatial and temporal cell death pattern. The distinct features of chromatin condensation and nuclear DNA fragmentation indicate that programmed cell death is involved. In addition, satRNA localization and(More)
LEAFY COTYLEDON1 (LEC1) is a B subunit of Nuclear Factor Y (NF-YB) transcription factor that mainly accumulates during embryo development. We cloned the 5' flanking regulatory sequence of AhLEC1B gene, a homolog of Arabidopsis LEC1, and analyzed its regulatory elements using online software. To identify the crucial regulatory region, we generated a series(More)
