Plant Ontology Annotations:

• PO:0009005  — root — raíz (Spanish, exact), radices (exact, plural), radix (exact), 根 (Japanese, exact), aerial root (narrow), climbing root (narrow)
• 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:

• SALK_052575  — similar to mia-1 and mia-2
• SALK_077682  — similar to mia-1 and mia-2
• mia-1  — Mutant plants exhibit a severe reduction in fertility and markedly reduced size of the siliques. Mutant microspores fail to separate from tetrads and pollen grains are fragile with an abnormal morphology and altered cell wall structure. Consequently, pollen grain was mostly not released from open anthers, and those that were released, appeared as pollen tetrads. Pollen germination in vitro was very poor, compared to the wild type pollen. In addition, mutant plants suffer from imbalances in cation homeostasis.
