“…For instance, the rice root contains exodermis and sclerenchyma cell layers, which are absent from Arabidopsis. Furthermore, the multilayered cortex of the rice root can differentiate into aerenchyma, an anatomical adaptation to water submergence, at late developmental stages, a capacity that is absent in Arabidopsis 53 . The expression map of the rice root tip at single-cell resolution presented in this study provides a valuable resource for defining different cell types.…”

“…In addition to lateral auxin transport, localized auxin biosynthesis occurring within rice shoots also regulates shoot gravitropic responses. OsHOX1 and OsHOX28 are two negative regulators that act upstream of HSFA2D and LAZY1, and inhibit the expression of multiple YUCCA genes in rice and decrease auxin biosynthesis following gravistimulation (Hu et al, 2020). Tiller Angle Control 4 (TAC4) also influences several IAA biosynthetic genes, including YUCCA and TAR2 (TRYP-TOPHAN AMINOTRANSFERASE OF ARABIDOPSIS), and regulates auxin biosynthesis and auxin distribution patterns in rice (Li et al, 2021).…”

“…Nipponbare cDNA using gene‐specific primers to which a Kpn I restriction site was added (Table ). The products were gel purified, cloned in the Kpn I restriction site downstream of the ubiquitin promoter in the binary vector pU1301 (Hu et al., 2020), and confirmed by DNA sequencing. The hygromycin resistance gene carried by pU1301 was used for the selection of transformed rice calli.…”
