Plant Ontology Annotations:

• PO:0000084  — plant sperm cell — célula espermática o esperma (Spanish, exact), male gamete (exact), microgamete (exact), 植物精子細胞 (Japanese, exact), sperm nucleus (related), sperm cell (broad)

Germplasm Phenotype:

• CS9388  — In the absence of vernalization, the double mutant flowered at the same time as the fca-1 single mutant.
• CS9388  — Reduced response of fca-1 to vernalization; under typical long-day (16h) photoperiods, vrn1-1 fca-1 flowers with about 25 leaves without vernalization and with about 20 leaves after vernalization; the diameter of the vegetative rosette is smaller than fca-1 alone; older leaves develop grayish-brown necrotic lesions.
• vrn1-2  — No delay in flowering but reduction in vernalization response.
• vrn1-2 fca-1  — Strong delay in flowering and vernalization response.
