Finally, Targeting Induced Local Lesions In Genomes (TILLING) and EcoTILLING, which allow identification of point mutations and allelic variability in specific genes, can be applied to any species where mutagenised EMS-populations are available or to germplasm collections (Colbert et al., 2001; Comai et al., 2004; Tsai et al., 2011). Natl. Curr. Plant Sci. Interestingly, more flowers do not directly mean more pods, and triple-flower plants can only develop two pods per I2, because one of the three flowers, with a different morphology, does not set pod (Srinivasan et al., 2006). In contrast, it is not clear that a strategy to obtain semideterminate varieties through mutation will be possible because the causative mutation(s) of semideterminacy in soybean has not been fully elucidated yet, and also because they are gain-of-function mutations, most likely in regulatory regions of the Dt2 gene, which may be difficult to translate to other legume species (Ping et al., 2014).

Therefore, the number of secondary inflorescences (I2) produced by the primary inflorescence (I1), and the number of flowers produced by the secondary inflorescences, depends on for how long the I1 and I2 meristems, respectively, remain active. Agron. Appl. 53, 369–382. DET/PsTFL1a is expressed only after floral transition, in the I1 meristem, in agreement with its function as an I1 meristem identity gene (Foucher et al., 2003; Berbel et al., 2012).

In tfl1, the indeterminate inflorescence apex (I) is replaced by a terminal flower (F) while in ap1, the flowers are replaced by inflorescence-like structures. Plant Physiol. (2007). The soybean stem growth habit gene Dt1 is an ortholog of arabidopsis TERMINAL FLOWER1. Mutations in the TFL1 gene cause a conversion of the inflorescence meristems into floral meristems, producing the abrupt termination of the main inflorescence stem in a TFL and the substitution of lateral branches by solitary axillary flowers (Figure 2; Shannon and Meeks-Wagner, 1991; Alvarez et al., 1992; Schultz and Haughn, 1993). doi: 10.1093/aob/mcm146, Benlloch, R., D’erfurth, I., Ferrandiz, C., Cosson, V., Beltran, J.

National Center for Biotechnology Information, Unable to load your collection due to an error, Unable to load your delegates due to an error. Artificial selection for determinate growth habit in soybean. Studies in model legumes such as pea (Pisum sativum) or Medicago truncatula have led to a rather good knowledge of the genetic control of the development of the legume compound inflorescence. Apart from the isolation of mutants for the multiflower/multipod genes, an alternative strategy that also might lead to an increased number of flowers per I2 node could be to manipulate the expression of genes that control general meristem activity. From the axil of each leaf, inflorescence develops. Transition from vegetative to I1 meristem apparently takes place but the I1 meristem produces lateral meristems that, unable to acquire I2 identity, continue to develop as I1s, producing vegetative branches that replace I2 inflorescences (Figure 3; Gottschalk, 1979; Reid and Murfet, 1984; Berbel et al., 2012). The inset shows a close up of a secondary inflorescence with two flowers (pods) and the stub (arrowhead). Characterization of primary inflorescence markers in veg1 mutant discarded the possibility that the floral transition was blocked or delayed in this mutant. Inflorescence architecture: a developmental genetics approach. For instance, in crops such as tomato and grain legumes, determinate varieties have been traditionally selected because they show favorable traits for an efficient cultivation and harvest. 153, 198–210.

VEG1 is required to make secondary inflorescences. Plant Sci. Progress on the mapping of the chickpea SFL gene, responsible of the double- and triple-flower phenotypes, has been reported, which places SFL on LG6, (Rajesh et al., 2002; Gaur et al., 2011). Physiological-genetics of flowering in Pisum. Efficient discovery of DNA polymorphisms in natural populations by Ecotilling. This shows that in pea det mutants, rather than the conversion of the inflorescence meristem into floral meristem observed in Arabidopsis tfl1 mutants, what really takes place is the conversion of the I1 meristem into an I2 meristem (Figure 3; Singer et al., 1990). Nat. To date, no linkage analysis has been reported for CYM, the chickpea gene responsible of the multi-flower phenotype. Acad. doi: 10.1126/science.7824951. (2010). Bot. As mentioned above, legumes are characterized by a compound indeterminate inflorescence (Weberling, 1989b; Benlloch et al., 2007; Prenner, 2013; Hofer and Noel Ellis, 2014).

Genome sequence of the palaeopolyploid soybean. 678, 179–190. Rev. Genetic control of floral zygomorphy in pea (Pisum sativum L.). An APETALA1-like gene of soybean regulates flowering time and specifies floral organs. In soybean, semideterminate growth habit has been linked to a dominant mutation leading to high expression in the apex of the main inflorescence of DT2, a homolog of the pea I2 meristem identity gene VEG1 (Ping et al., 2014). However, a closer analysis reveals that the I1 meristem of det mutants do not directly form a (terminal) flower but, instead, it develops as a stem that produces a flower in a lateral position and terminates into a stub, like the I2s. Murfet, I. C., and Reid, J. The genetic control of flowering time in legumes is discussed in another review in this number (see Weller and Ortega, 2015, in this Research Topic). LEAFY interacts with floral homeotic genes to regulate Arabidopsis floral development. This function seems conserved in other grain legumes from the IRCL clade, as mutants in the L. japonicus and M. truncatula UNI homologs, LjLFY and SLG1, also show a strong reduction in the complexity of their leaves (Dong et al., 2005; Wang et al., 2008a). doi: 10.1105/tpc.12.8.1279, Grønlund, M., Constantin, G., Piednoir, E., Kovacev, J., Johansen, I. E., and Lund, O. S. (2008). Likewise, the I2 meristems of the pim mutants are eventually able to produce floral meristems; in these cases the meristems only acquire partial floral fate, as indicated by the production of flowers with bract-like organs and other floral identity defects (Taylor et al., 2002). Epub 2017 Jun 9. WUS homologs have been described in legumes and the available data suggest that they play the same function in meristem activity as in Arabidopsis (Wong et al., 2010).

The pea GIGAS gene is a FLOWERING LOCUS T homolog necessary for graft-ransmissible specification of flowering but not for responsiveness to photoperiod. In contrast, other plants have evolved to a more complex architecture and have compound inflorescences (Figure 1; Weberling, 1989a). Inflorescence traits amenable to improvement in legumes could be divided into two categories: (1) traits related to the identity of the meristems in the inflorescence apex, and (2) traits related to the activity of the inflorescence meristems. 10.1105/tpc.11.8.1405 Cloning and molecular analysis of the Arabidopsis gene terminal flower 1.

Plant Sci., 21 July 2015 Indeed, homologous genes of the major inflorescence regulators can be found in the sequence databases of several grain legumes (Table 1), therefore facilitating the identification of suitable alleles to breed inflorescence traits in the legume crop of interest. The number of flowers per I2 (multipod/multiflower) is an inflorescence trait related to the activity of the inflorescence meristem that might be amenable to improvement in grain legumes (Figure 4). VEGETATIVE1 is essential for development of the compound inflorescence in pea. (2003) also showed that the early flowering phenotype of recessive mutations in the pea LATE FLOWERING loci (LF, described by Weller and Ortega, in this Research Topic) was due to mutations in another TFL1-like gene, PsTFL1c, a paralogue of DET/PsTFL1a.

On the other hand, and according to the proposed genetic model, the non-flowering phenotype of pea veg1 mutants appears to be caused by ectopic expression of the TFL1-homolog DET gene in all the meristems in the inflorescence apex, which transforms the branches produced in the “inflorescence” apex into primary inflorescences (I1s) and inhibit the formation of flowers (Hecht et al., 2011; Berbel et al., 2012). doi: 10.1242/dev.158766. ...

(2004). Plant genome engineering in full bloom. A putative CENTRORADIALIS/TERMINAL FLOWER 1-like gene, Ljcen1, plays a role in phase transition in Lotus japonicus. Conversely, in a veg1 mutant, DET is ectopically expressed in the lateral meristems produced by the I1 and these lateral meristems then fail to acquire I2 identity, developing as I1 inflorescences. (2009). In the case of pea, where I2 meristems usually produce 1–2 flowers, several studies have identified loci responsible for limiting the number of floral meristems initiated by the I2 meristem before stub formation. Homologs of main regulators of inflorescence development in legumes. Thus, the veg2-1 mutant displays a non-flowering phenotype similar to veg1, while veg2-2, a weaker allele, shows a delay in flowering and a conversion of I2 inflorescences into flower-bearing branch-like structures with indeterminate growth, which resemble the primary I1 inflorescence of WT plants (Murfet and Reid, 1993). This category has only the following subcategory. eCollection 2018. Plant Cell 11, 1405–1418. 3:797. doi: 10.1038/ncomms1801, Berbel, A., Navarro, C., Ferrandiz, C., Cañas, L. A., Madueño, F., and Beltran, J. P. (2001). In plants with an indeterminate growth habit, such as grain legumes, the SAMs produce lateral structures, branches and flowers, while they remain active. Curr. The Medicago genome provides insight into the evolution of rhizobial symbioses. Classical studies indicate that this trait is controlled by two genes, Fn and Fna, whose single recessive mutations cause an increase in the number of flowers per I2, being higher in the double recessive genotypes, the so-called multipod phenotype (White, 1917; Lamprecht, 1947). Front. 6:207. doi: 10.3389/fpls.2015.00207. Thus, in double ap1 cal mutants, inflorescence meristems produce new meristems that completely fail to acquire floral fate behaving like new inflorescence meristems that continue to divide, producing proliferating structures with cauliflower morphology (Bowman et al., 1993; Kempin et al., 1995; Mandel and Yanofsky, 1995). 31, 688–691. In contrast, legumes represent a more complex inflorescence type, the compound inflorescence, where flowers are not directly borne in the main inflorescence axis but, … B. Plant Physiol. In summary, the increasing availability of genomic tools and resources offers a unique opportunity to accelerate breeding of inflorescence architecture and, in general, of agronomic important traits in legumes. Keywords: In the world of legumes, records surpassing such lengths are very rare and are not well authenticated. This has lead to the attractive idea that the TFL1 function, which in Arabidopsis controls both the vegetative and the inflorescence phases (Ratcliffe et al., 1998), in pea would be divided between two genes, DET and LF (Foucher et al., 2003). 46, 1337–1342.

In addition to these genetic factors, the number of flowers per I2 is also affected by growing conditions (Hole and Hardwick, 1976; Murfet, 1985; Singer et al., 1999) and mutations in the flowering time genes HIGH RESPONSE (HR) and STERILE NODES (SN), involved in photoperiod response, also strongly influence this trait, with the number of flowers being decreased by recessive sn alleles and increased by dominant HR alleles (Murfet, 1985; Reid et al., 1996; Weller et al., 2012; Liew et al., 2014). a) mulberry.

Finally, as it was also observed that loss-of-function of PIM leads to a missexpression of VEG1 in the newly formed “floral” meristems, this ectopic VEG1 expression would explain why these meristems do not acquire floral fate but instead develop as I2 meristems. Nonetheless, much work still needs to be done and genomics and related disciplines will be of great help to speed up progress in this area.
