'''shoot-borne root (PO:0000042''')- dealt with above

'''crown root (PO:0000043)-'''
proposed def: "A nodal root formed at the crown of the plant (as in corn where the crown is below the soil surface)." [TAIR:ki]
comment: Definition changed to eliminate adventitious. This is still within the sense of the TAIR definition.
is_a: PO:0003005 ! nodal root

'''prop root (PO:0000044)-'''
proposed def: "A root formed at stem nodes above the ground and growing directly into the soil." [TAIR:ki]
comment: This term is perhaps best defined functionally to prop the plant up.
synonym: "brace root" EXACT
is_a: PO:0003005 ! nodal root

'''embryonic root (PO:0000045)-'''
proposed def: "Root that is initiated in the developing embryo." [TAIR:ki]
synonym: "radicle" EXACT
relationship: part_of PO:0009009

'''seminal root (PO:0000046)-'''
proposed def: "A basal root formed within the hypocotyl of the embryo." [ISS:Weinhold1967 "Weinhold L. 1967. Histogenetic studies of rht boundary root problem [Histogenetische Studien zum Grenzwurzelproblem]. Beitr. Biol. Pflanzen 43:367-454.", TAIR:ki]
comment: Definition changed to represent the relationship to basal root.
synonym: "scutellar nodal root" RELATED
synonym: "secondary root" BROAD

'''nodal root (PO:0003005)-'''

alt_id: PO:0003009
def: "A shoot-borne root that forms at a shoot node rather than an internode." [http://www.botgard.ucla.edu/html/botanytextbooks/generalbotany/typesofroots/]
comment: Cleaned up the definition to fit ISRR terminology.
is_a: PO:0000042 ! shoot-borne root

'''scutellar node (PO:0004708)'''
proposed def: "The region in the embryo between the primary root (enclosed in the coleorhiza) and the plumule (enclosed in the coleoptile) to which the scutellum is attached." [MaizeGDB:lv, TAS:Esau1965 "Esau, K. 1965. Plant Anatomy. New York. Wiley. pp. 767", TAS:Fahn1990 "Fahn A. 1990. Plant Anatomy 4th Ed. Elsevier."]
comment: Scutellar node is specifically for corn. In general it refers to the mesocotyl which is for monocots in general, and the hypocotyl is a term appropriate for all plants.
synonym: "hypocotyl" EXACT
synonym: "mesocotyl" EXACT
relationship: part_of PO:0009009

'''hypocotyl-root junction (PO:0004724)'''

relationship: part_of PO:0019018

'''root (PO:0009005)'''
alt_id: PO:0003006
proposed def: "A plant organ which is usually underground and more or less positively geotropic, only rarely bears shoots. Primary functions are support and absorption of water and minerals. There are four primary types of root taproot, basal root shoot-borne root and lateral root." [TAS:Fahn1990 "Fahn A. 1990. Plant Anatomy 4th Ed. Elsevier.", TAS:Zobel2009 "Zobel RW. 2009 Report of the Root Nomenclature Workgroup ISRR V (1996) a Reprise.

'''mesocotyl (PO:0020037)'''

'''lateral root (PO:0020121)'''

comment: Those roots that branch off axile roots are first order laterals. The branches off of first order laterals are second order. etc.
