Mean symptom severity index (Standard Deviation above 0 in parenthesis) of virus infection on plants expressed 35 dpi.

The presence (Y) or absence (N) of an insertion/deletion (indel) mutation in the RDR1 is indicated. GenBank accession codes of partial RDR1 coding sequences are given.
aYTMMV, yellow tailflower mild mottle virus; BYMV, bean yellow mosaic virus: CMV, cucumber mosaic virus; TSWV, tomato spotted wilt virus.
bMean symptom indices (Standard deviation)
0. Systemic infection not detected
1. No visible symptoms of infection.
2. Mild symptoms of chlorosis, mosaic and/or leaf deformation evident. Slight stunting may be evident. Ring patterns or small necrotic spots sometimes visible. Little to no obvious impact on the numbers of flowers or viable seed produced.
3. Moderate symptoms of chlorosis, mosaic and/or leaf deformation. Moderate to significant stunting of growth and small necrotic patches may be present. Some flowers and seed may be produced.
4. Large patches of leaf/stem necrosis, severe stunting. Plant remained alive.
5. The plant was dead.
NL = necrotic lesion; rings = ring patterns

本研究标注了RDR1基因中插入/缺失（indel）突变的存在（Y）与缺失（N）情况，并给出了部分RDR1编码序列的GenBank数据库登录号。
a YTMMV：尾穗苋轻斑驳病毒（yellow tailflower mild mottle virus）；BYMV：菜豆黄化花叶病毒（bean yellow mosaic virus）；CMV：黄瓜花叶病毒（cucumber mosaic virus）；TSWV：番茄斑萎病毒（tomato spotted wilt virus）。
b 症状指数平均值（标准差）
0：未检测到系统侵染
1：无可见侵染症状
2：出现轻度褪绿、花叶和/或叶片畸形，可伴随轻度矮化，偶见环纹或小型坏死斑点；对开花数量及可育种子产量无明显影响或影响极微
3：出现中度褪绿、花叶和/或叶片畸形，生长受抑程度为中度至显著，可见小型坏死斑；可产生部分花朵与种子
4：出现大面积叶/茎坏死斑，植株严重矮化但仍存活
5：植株死亡
NL = 坏死斑；rings = 环纹
本数据集统计了接种后35天（dpi）植株病毒侵染的平均症状严重度指数，括号内标注标准差且标准差大于0。
