View all With the introduction of a novel genetic function, represented by VEG1, which is placed in between the mutual antagonistic activities of DET and PIM, the pea model explains elegantly how the transient I2 meristem appears and, hence, the development of the compound inflorescence in legumes. 2018 Feb 8;145(3):dev158766.

Similar to veg1, gigas mutants show apparently normal vegetative development, and later in development, the induction of inflorescence markers, such as upregulation of DET and bud outgrowth (Beveridge and Murfet, 1996; Hecht et al., 2011), indicating that transition from vegetative to I1 meristem also takes place in gigas mutants.

Particularly interesting is the specification of the secondary inflorescence (I2) meristem, as the formation of these meristems is crucial for the development of higher order inflorescences and hence for the formation of the characteristic legume compound inflorescences.

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).

Arabidopsis thaliana, where the genetic control of inflorescence development is best known, has a simple inflorescence, where the primary inflorescence meristem directly produces the flowers, which are thus borne in the main inflorescence axis. According to the proposed model, elevated expression of a VEG1 gene in the apical I1 meristem should repress DET expression and cause determination, hence the phenotype of the dt2 mutants is consistent with the proposed repression of DET by VEG1 also being conserved in other grain legumes.

The development of the Arabidopsis inflorescence can be mostly explained by the function and mutual regulation of three genes: TERMINAL FLOWER 1 (TFL1), LEAFY (LFY), and APETALA 1 (AP1) (Shannon and Meeks-Wagner, 1993; Liljegren et al., 1999; Blazquez et al., 2006). Its pattern of expression is similar to AP1, being uniformly expressed in floral meristems at early stages and restricted to the sepal and petal primordia in later stages.

However, expression of PIM and VEG1 is never induced under LD in the inflorescence of the gigas mutants, which indicates that I2 specification does not take place (Hecht et al., 2011; Berbel et al., 2012).

Apical senescence in Pisum: a direct or indirect role for the flowering genes ? (2014). 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. On the contrary, in indeterminate inflorescences the SAM is never converted into a floral meristem and the inflorescence meristem continues producing floral meristems until senescence, as for example, occurs in the model plant species Arabidopsis thaliana (Figure 1; Weberling, 1989a; Benlloch et al., 2007). However, in pea, and in most legume species, there are several FT genes, comprising three distinct clades; analysis of pea FT genes has revealed a much more complex regulation of photoperiodic flowering in pea compared to Arabidopsis, with different FT homologs expressed in leaf and/or apex, and displaying different responsiveness to photoperiod (described by Weller and Ortega, 2015, in this Research Topic).

In the last years, the underlying mutations of some of these phenotypes have been identified, and these have been shown to affect DET/PsTFL1a homologs (Avila et al., 2007; Liu et al., 2010; Repinski et al., 2012; Dhanasekar and Reddy, 2014; Mir et al., 2014). 7, 430–441. 45, 195–201. Genetic coefficients in the CROPGRO–soybean model. Pisum Newslett. These phenotypic alterations are also observed in 35S::AP1 plants and indicate that PIM specifies floral meristem identity, being its expression in the inflorescence meristem sufficient to convert it into a floral meristem. Second, the virus induced gene silencing (VIGS) methods are available to several legume species such as pea, soybean, common bean, Latirus odorata and M. truncatula (Constantin et al., 2004; Grønlund et al., 2008; Zhang et al., 2010). 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. doi: 10.2134/agronj2010.0300, Kapoor, R.

Hence, meristems produced by the SAM after floral transition in loss-of-function lfy mutants have problems to acquire floral identity and retain features typical of inflorescence meristems. A common mechanism controls the life cycle and architecture of plants. (2008). Plant Cell 15, 2742–2754. An alternative strategy that might allow obtaining semideterminate varieties in grain legumes would be the generation of plants overexpressing Dt2/VEG1. Ann. Science 309 1052–1056. AP1; TFL1; VEG1; inflorescence architecture; legumes; meristem identity; pea. The identity of the floral meristems produced by the I2 is controlled by PIM, the homolog of AP1. In pea, floral meristem identity is controlled by the homologs of the LFY and AP1 genes from Arabidopsis. In some cases, the number of I2 (flowering) nodes has been found to limit yield in legume crops (Roche et al., 1998; Kahlon et al., 2011), which indicates that the number of flowering nodes is a trait with the potential to improve yield. Plant Sci. doi: 10.1126/science.7824951. Devi J, Mishra GP, Sanwal SK, Dubey RK, Singh PM, Singh B. PLoS One. Rev. Upon floral transition, the SAM becomes an inflorescence meristem that, either directly or in flower-bearing shoots, produces the floral meristems that form the flowers. Arrowheads, indeterminate shoot; open circles, flowers, closed circles, abnormal flowers. 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). Development and control of the number of flowers per node in Pisum sativum L. Ann. 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, legumes represent a more complex inflorescence type, the compound inflorescence, where flowers are not directly borne in the main … Besides, there is also a special type of inflorescence which fits into none of these groups. 40, 622–631. As mentioned before, while wild accessions of most grain legumes have an indeterminate growth habit, where the main (primary) inflorescence meristem continues growing and producing lateral (secondary) inflorescences until its senescence, in many legume crop species determinate varieties exist, in which the growth of the primary inflorescence meristem is interrupted, soon after onset of flowering, by the production of a terminal inflorescence (Figures 3 and 4; Singer et al., 1990; Tian et al., 2010; Kwak et al., 2012). Crit. The availability of genome sequences and other genomic resources should greatly facilitate the translation of basic knowledge obtained in a few legume models to the breeding of legume crops, and the reader is referred to recently published reviews on this subject for more details (Bolger et al., 2014; Varshney et al., 2014a,b). (2014).  |  The number of leaflets is reduced in uni mutant and tendrils are not formed. In addition, the increasing availability of genetic and genomic tools for legumes is allowing to rapidly extending this knowledge to other grain legume crops. (2008a). (2011). Plant Cell 3, 771–781. 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). The pea VEGETATIVE2 gene is an FD homolog that is essential for flowering and compound inflorescence development. However, pim I2 meristems, rather than producing floral meristems, produce new I2 meristems in a reiterative manner (Figure 3; Taylor et al., 2002; Berbel et al., 2012), somehow resembling the proliferative inflorescences of the Arabidopsis ap1 cal double mutant (Kempin et al., 1995). In the world of legumes, records surpassing such lengths are very rare and are not well authenticated. Périlleux C, Bouché F, Randoux M, Orman-Ligeza B.

Expression of UNI in pea floral meristems is detected in developing floral organ primordia, declining as they expand. 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). 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. Consistent with this model, the missexpression of VEG1 in the inflorescence apex of det mutant plants would cause the apical meristem to acquire I2 identity and to develop as a terminal I2. Therefore, the tfl1 mutation changes the Arabidopsis inflorescence from an indeterminate to a determinate type.

In addition, different reverse genetic and genomic tools that can be used to validate the function of candidate genes for architectural traits are now available in several model and non-model legume species. In contrast, legumes represent a more complex inflorescence type, the compound inflorescence, where flowers are not directly borne in the main inflorescence axis but, … The SAM is located at the tip of the plant shoot and contains a central pool of stem cells that are able to self-maintain together with peripheral dividing cells required for organ initiation (Steeves and Sussex, 1989).

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. Legume crops phylogeny and genetic diversity for science and breeding. Huala, E., and Sussex, I. M. (1992). The genetic basis of I2 meristem identity acquisition was elucidated by the analysis of a pea mutant in the VEGETATIVE1 (VEG1) locus. This simple model based on the DET/VEG1/PIM regulatory module (Figure 3) is a more complex version of the TFL1/LFY/AP1 model (Figure 2) that explains the development of the Arabidopsis simple inflorescence.

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).
