Increased planting densities have boosted maize yields. Upright plant architecture facilitates dense planting. Here, we cloned UPA1 (Upright Plant Architecture1) and UPA2, two quantitative trait loci conferring upright architecture. UPA2 is controlled by a two-base sequence polymorphism regulating the expression of B3-domain transcription factor (ZmRAVL1) located 9.5 kilobases downstream. exhibits differential binding DRL1 (DROOPING LEAF1), physically interacts with LG1 (LIGULELESS1)...
Summary Flowering time is a major determinant of the local adaptation plants. Although numerous loci affecting flowering have been mapped in maize, their underlying molecular mechanisms and roles remain largely unknown. Here, we report identification characterization MADS ‐box transcription factor Zm 69 that functions as activator through ZmRap2.7‐ ZCN 8 regulatory module contributes to adaptation. We show underlies quantitative trait locus controlling difference between maize its wild...
Flowering time is a key trait determining the local adaptation of plants. CONSTANS (CO) core regulator controlling photoperiodic flowering in Arabidopsis (Shim et al., 2017). Heading date 1 (Hd1), CO ortholog rice, promotes heading under short-day (SD) conditions but inhibits long-day (LD) (Yano 2000). Miller al. (2008) identified constans Zea mays1 (conz1), maize homologue, that exhibited distinct diurnal expression patterns varied photoperiods. However, how conz1 contributes to variation...
