ACL5 / ACAULIS 5: Encodes a spermine synthase. Required for internode elongation and vascular development, specifically in the mechanism that defines the boundaries between veins and nonvein regions. This mechanism may be mediated by polar auxin transport. Though ACL5 has been shown to function as a spermine synthase in E. coli, an ACL5 knockout has no effect on the endogenous levels of free and conjugated polyamines in Arabidopsis, suggesting that ACL5 may have a very specific or altogether different in vivo function.
Process: Auxin polar transport, phloem or xylem histogenesis (Clay and Nelson 2005) and vessel member cell differentiation (Hanzawa et al. 1997).
AGI: AT5G19530. Pop. Ort.: POPTRDRAFT_717791 - estExt_Genewise1_v1.C_LG_VI2502 / spermine synthase/ thermospermine synthase / (Clay and Nelson 2005; Imai et al. 2006; Muniz et al. 2008; Kakehi et al. 2008; Baucher et al. 2007)
ACR4 / ARABIDOPSIS CRINKLY4: Encodes a membrane localized protein with similarity to receptor kinases which is involved in epidermal cell differentiation. Flowers of mutants have disorganized ovule integument growth and abnormal sepal margins. In the roots, mutants initiate more lateral roots but fewer laterals actually emerge due to defects in lateral root formation. Mutants also display disorganized columella. The root phenotypes can be traced to abnormalities in asymmetric divisions in the pericycle and root apex. Conflicting data regarding the role of the kinase domain- which may or may not be required for function. Complementation studies indicate that the C-terminal domain is also not required for signalling function. May be regulated by protein turnover which is mediated by endocytic processes.
Process: Embryonic development ending in seed dormancy (Tanaka et al. 2002), lateral root formation, regulation of asymmetric cell division and root cap development (De Smet et al. 2008).
