Chromosome No. 7
Explanation Frizzy plants produce no seed, being propagated as heterozygotes. Development of the rachis branches appears to be normal, but small branches continue to be formed instead of spikelets. These branches appear to produce multiple rachillas. [238] fzp is located on chromosome 7 flanked by markers R1789 bs 3817R. ETHYLENE RESPONSIVE ELEMENT BINDING FACTOR. AB103120. AB568302. qSBN7 (SECONDARY BRANCH NUMBER7) is a novel allele of FZP (Wang et al. 2020). TO:0000975: grain width. PO:0030123: panicle inflorescence. TO:0000847: panicle inflorescence morphology trait. GO:1902510: regulation of apoptotic DNA fragmentation. TO:1000023: lemma morphology trait. TO:1000024: palea morphology trait. TO:0000978: glume shape.
Trait Class Reproductive organ - Inflorescence
Reproductive organ - panicle
