Ed with TristichoideaeKatayama et al. investigated the mechanisms underlying shoot improvement in Podostemaceae by expression evaluation of important developmental regulatory gene orthologues in model eudicots. STM (SHOOT MERISTEMLESS) and WUS are needed for the formation and maintenance with the SAM in eudicots (like arabidopsis), and ARP (ASYMMETRIC LEAVESROUGH SHEATHPHANTASTICA) promotes leaf identity (Gallois et al ; Langdale and Harrison, ; Takeda and Aida,). Inside the tristichoid shoots (e.g. Terniopsis minor), STM and WUS orthologues have been expressed in the prominent SAMs, as in model plants (e.g. arabidopsis). Within the podostemoid shoots (e.g. Hydrobryum japonicum, Cladopus doianus and Zeylanidium lichenoides) with cryptic (indistinct) SAMs, the STM and WUS orthologues are expressed within the initiating leaf primordia. The 
leaves in Podostemoideae produce cryptic GSK-2881078 chemical information meristems close to their bases, which bulge as a brand new SAM and subsequently differentiate into a terminal leaf. WUS expression soon disappears inside the establishing leaf primordia, and STM expression is restricted to their basal parts, whereas ARP is expressed in their distal parts within a complementary pattern to STM expression. As a result, the SAM in podostemoids (at the least Asian ones) appears to possess been converted into a single, terminal leaf by losing the expression of genes (STMWUS) responsible for continued stem growth and gaining expression of genes (ARP) that market leaf identity. Consequently, the leaves have `a mixture of shoot and leaf, displaying fuzzy morphology’ (Kato p.). In line with the evolutionary model proposed by Katayama et al. , the shoots in Podostemoideae develop by repetitive formation of stem eaf mixed organs and this pattern is derived from the sympodial shoot branching of Tristichoideae and Weddellinoideae. The early loss of embryonic shoot and root meristems (i.e. shortlived plumules and radicles) in riverweed seedlings is equivalent to MONOPTEROS and also other mutants identified in arabidopsis (Treml et al ; Katayama et al ; Takeda and Aida, ).Epiphytic epilithicJ L A a R ALA AJLA A aA aaAU. longifoliaJ LA A u LU. alpinaAquatic terrestrialL R AJ a a a u AA uA LU. sandersoniiU. vulgaris s.l.FIG. .
