“…The levels of IAA found in the gametophytes and sporophytes are similar to those detected in the water fern Salvinia molesta (Arthur et al 2007) and in sporophytic tissue of Psilotum nudum (Abul et al 2010). Also, a certain degree of uniformity is observed in the cytokinin content.…”

“…The levels of tZ detected were the lowest, \5 pmol/g DW. Levels particularly high of tZR and iP were recently found in sporophytic tissue of P. nudum (Abul et al 2010). Following with lower plants, Ivanova et al (1992) reported that Chlamydomonas reinhardtii had high amounts of iP-type cytokinins (90%); tZ and DHZ were also present.…”

“…In sporophytic tissues of P. nudum, the non-hydroxylation pathway appears to be preferential, with a strong presence of GA 4 (Abul et al 2010). In other species of ferns such as B. spicant, analyses of gametophytic and sporophytic tissues have revealed the presence of a wider range of GAs belonging to either the early 13-OH pathway or the non-OH pathway (Menéndez et al 2006).…”

“…The differentiation pattern followed by gametophyte and sporophyte cells in ferns may be affected by both nutritional and environmental factors, and includes the loss of close cell to cell communication and subsequent washing out of certain bioactive compounds (Lucas et al 2009;Wang and Fiers 2010), and the content dynamics and potential functioning of phytohormones affecting several developmental processes in ferns such as germination, sex determination, alternation of generations without fertilization (apogamy) or sporogenesis (apospory), etc. (Banks 1999;Kazmierczak 2003;Menéndez et al 2006Menéndez et al , 2009Greer et al 2009;Abul et al 2010;Somer et al 2010).…”

The fern Asplenium nidus L. is in great demand as an ornamental plant. The aim of this work was to investigate the influence of phytohormones in promoting a gametophytic and sporophytic growth in homogenized sporophytes tissue. Exogenous application of 0.5 and 5 lM N 6 -benzyladenine, 0.05 and 0.5 lM indole-3-acetic acid (IAA), and 0.3 and 3 lM gibberellic acid (GA 3 ) favoured sporophyte regeneration, whereas gametophyte regeneration took place when plant material was cultured in a hormone-free liquid MS medium. The endogenous contents of the auxin IAA, the cytokinins trans-zeatin, transzeatin riboside, dihydrozeatin, dihydrozeatin riboside, isopentenyladenine and isopentenyladenosine, and the gibberellins GA 1 , GA 3 , GA 4 , GA 7 , GA 9 and GA 20 in growing gametophytes and sporophytes were evaluated. Similar levels of the auxin and cytokinins and qualitative differences in the gibberellins were found between both generations.

“…Thus, the regenerative competence of sporophytes was put to test in these taxa of plants. Intriguingly in ferns, plant explants of the gametophyte showed remarkable potential for regeneration in hormone free medium (Banks, 1999; Kazmierczak, 2003; Menendez et al, 2009; Abul et al, 2010; Somer et al, 2010). While in the sporophyte though the potential for regenerating an excised organ remained, the explants were recalcitrant to regenerate an entire organism when no external hormone is supplied (Ferna'ndez et al, 1993, 1997).…”

Competence and regulatory interactions during regeneration in plants

The ability to regenerate is widely exploited by multitudes of organisms ranging from unicellular bacteria to multicellular plants for their propagation and repair. But the levels of competence for regeneration vary from species to species. While variety of living cells of a plant display regeneration ability, only a few set of cells maintain their stemness in mammals. This highly pliable nature of plant cells in-terms of regeneration can be attributed to their high developmental plasticity. De novo organ initiation can be relatively easily achieved in plants by proper hormonal regulations. Elevated levels of plant hormone auxin induces the formation of proliferating mass of pluripotent cells called callus, which predominantly express lateral root meristem markers and hence is having an identity similar to lateral root primordia. Organ formation can be induced from the callus by modulating the ratio of hormones. An alternative for de novo organogenesis is by the forced expression of plant specific transcription factors. The mechanisms by which plant cells attain competence for regeneration on hormonal treatment or forced expression remain largely elusive. Recent studies have provided some insight into how the epigenetic modifications in plants affect this competence. In this review we discuss the present understanding of regenerative biology in plants and scrutinize the future prospectives of this topic. While discussing about the regeneration in the sporophyte of angiosperms which is well studied, here we outline the regenerative biology of the gametophytic phase and discuss about various strategies of regeneration that have evolved in the domain of life so that a common consensus on the entire process of regeneration can be made.
