“…GA has also been reported to affect growth and development of male reproductive cells (antheridia) in Chara by up-regulating sperm production and endoreplication of support cells (Kwiatkowska et al 1998). Classical GA-signaling and perception proteins have not been found in charophyte algae (Vandenbussche et al 2007), although genomic information is unavailable so this negative result awaits confirmation.…”

The green lineage of chlorophyte algae and streptophytes form a large and diverse clade with multiple independent transitions to produce multicellular and/or macroscopically complex organization. In this review, I focus on two of the best-studied multicellular groups of green algae: charophytes and volvocines. Charophyte algae are the closest relatives of land plants and encompass the transition from unicellularity to simple multicellularity. Many of the innovations present in land plants have their roots in the cell and developmental biology of charophyte algae. Volvocine algae evolved an independent route to multicellularity that is captured by a graded series of increasing cell-type specialization and developmental complexity. The study of volvocine algae has provided unprecedented insights into the innovations required to achieve multicellularity.

“…GA-Type Diterpene Produced from ent-Kaurene Is Involved in Protonemal Development GA 3 and GA 4 are active GAs in angiosperms, but these compounds did not show any profound effects on P. patens at physiological concentration (Vandenbussche et al, 2007;Yasumura et al, 2007). GA 9 methyl ester and GA 73 methyl ester have been identified as antheridiogens that induce antheridium formation in the schizaeaceous fern Lygodium, but they are inactive GAs in angiosperms (Yamauchi et al, 1996;Kurumatani et al, 2001).…”

“…Genome sequence for these organisms has enabled the identification of genes orthologous to flowering plant genes encoding GA biosynthetic enzymes and GA signaling components involved in the GID1-DELLA pathway (Hirano et al, 2007;Vandenbussche et al, 2007). Recently, two reports demonstrated that GID1-DELLA-mediated signaling is functionally conserved in the fern Selaginella and in angiosperms (Hirano et al, 2007;Yasumura et al, 2007).…”

“…Abscisic acid mediates the establishment of tolerance to dehydration, cold temperature, and osmotic stresses in P. patens as in angiosperms (Decker et al, 2006;Cho et al, 2009;Khandelwal et al, 2010). In contrast to these hormones, there are only a few studies on the physiological activity of GA in mosses (Von Maltzahn and Macquarrie, 1958;Chopra and Mehta, 1987;Vandenbussche et al, 2007), and the GA function and signaling pathways are still unclear.…”

Endogenous Diterpenes Derived from ent-Kaurene, a Common Gibberellin Precursor, Regulate Protonema Differentiation of the Moss Physcomitrella patens

Gibberellins (GAs) are a group of diterpene-type plant hormones biosynthesized from ent-kaurene via ent-kaurenoic acid. GAs are ubiquitously present in seed plants. The GA signal is perceived and transduced by the GID1 GA receptor/DELLA repressor pathway. The lycopod Selaginella moellendorffii biosynthesizes GA and has functional GID1-DELLA signaling components. In contrast, no GAs or functionally orthologous GID1-DELLA components have been found in the moss Physcomitrella patens. However, P. patens produces ent-kaurene, a common precursor for GAs, and possesses a functional entkaurene synthase, PpCPS/KS. To assess the biological role of ent-kaurene in P. patens, we generated a PpCPS/KS disruption mutant that does not accumulate ent-kaurene. Phenotypic analysis demonstrates that the mutant has a defect in the protonemal differentiation of the chloronemata to caulonemata. Gas chromatography-mass spectrometry analysis shows that P. patens produces ent-kaurenoic acid, an ent-kaurene metabolite in the GA biosynthesis pathway. The phenotypic defect of the disruptant was recovered by the application of ent-kaurene or ent-kaurenoic acid, suggesting that ent-kaurenoic acid, or a downstream metabolite, is involved in protonemal differentiation. Treatment with uniconazole, an inhibitor of ent-kaurene oxidase in GA biosynthesis, mimics the protonemal phenotypes of the PpCPS/KS mutant, which were also restored by entkaurenoic acid treatment. Interestingly, the GA 9 methyl ester, a fern antheridiogen, rescued the protonemal defect of the disruption mutant, while GA 3 and GA 4 , both of which are active GAs in angiosperms, did not. Our results suggest that the moss P. patens utilizes a diterpene metabolite from ent-kaurene as an endogenous developmental regulator and provide insights into the evolution of GA functions in land plants.

Since their discovery, gibberellin (GA) diterpenoid phytohormones have been used by agriculturalists and horticulturalists to control plant growth and to improve yield quantity and quality. Coordinated breeding efforts after World War II have led to strong yield increases following the introduction of dwarfing alleles that impair GA signalling in wheat and GA biosynthesis in rice, later named the ‘Green Revolution’. In the last two decades, the identity of the basic components of the GA signal transduction pathway has been elucidated. Core to GA action is the regulation of DELLA protein levels, repressors that control plant growth by negatively interfering mainly, but as it emerges not exclusively, with transcription regulator activities. Here, the author summarises the current knowledge of GA signal transduction, thereby putting an emphasis on the crosstalk of GA signalling with the light and jasmonic acid signalling pathways and with microtubule organisation. Key Concepts: Manipulation of gibberellin (GA) signalling has contributed to the ‘Green Revolution’. DELLA proteins are GA‐labile growth repressors that mainly, but not exclusively, repress transcription factors. GA inactivates DELLAs by targeting them for degradation by the ubiquitin–proteasome system. Alternative GA‐independent DELLA inactivation mechanisms have been described. GA and DELLAs repress PIF and BZR1 transcription factors to control light‐regulated development. GA and DELLAs antagonistically control different steps in the signal transduction of the phytohormone jasmonic acid. GA and DELLAs modulate microtubule formation by modulating prefoldin activity.
