“…As shown in previous studies (Sunkar and Jagadeeswaran, 2008), most miRNAs from the gynophore are highly conserved in different plant species, indicating that ancient regulatory pathways of conserved miRNAs are present in the peanut gynophore (Li et al, 2016). miRNA members of different gynophore stages were compared with each other and great differences were found between any two stages.…”

ABSTRACT. Peanut is one of the most important oilseed crops in the world that provides a significant amount of lipids and protein for many people. The gynophore plays an important role in gynophore development after fertilization of the peanut ovule. MicroRNAs (miRNAs) play an important role in numerous developmental and physiological plant processes. Therefore, it is essential to analyze the miRNA sequences at different gynophore stages to explore and validate gene function. Multiple small RNAs were sequenced and collected from gynophore stages A1, A2, and A3 (5, 10, and 20 days of development, respectively) for further prediction. We obtained 266 known and 357 novel miRNAs from the three different stages. Stage A3 had the largest number of reads. Genes involved in the lignin catabolic process 2 Y. Shen et al. Genetics and Molecular Research 15 (4): gmr15048691were identified only at stage A1. The copper ion-binding process also specifically emerged at stage A1, whereas negative regulation of biological processes occurred only in stages A2 and A3. The genes related to growth were found only at stage A3, suggesting that the gynophore may contribute to rapid development of the gynophore at this stage. Our identification and assessment of miRNAs from different gynophore stages may serve as a basis for further studies of gynophore miRNA regulation mechanisms. Some biological processes were specifically regulated at different gynophore stages indicating that miRNAs play an important role in the gynophore development.

“…The expression levels of BjuSBP05, 06, 07 and 08 belonging to group G1 were high and similar in all the four stages of stem development. Similarly, the transcriptome data showed that most genes belonging to the G3 and G4 in the four stages were highly expressed in early stages of development but down-regulated in maturation, similar to peanut seed formation [46]. The expression of some genes belonging to G2 and G6 was very low at all the stages, whereas some SlySBP genes in tomatoes were hardly expressed during fruit development [12].…”

The SQUAMOSA promoter binding protein (SBP)-box consists of a family of transcription factors unique to plants and mediates important roles in plant growth and development. We identified 57 SBP genes in the Brassica juncea (swollen-stem mustard) genome, and analyzed the structural characteristics, evolutionary relationships, as well as their involvement in regulation and response to environmental stress. By the help of phylogenetic analysis, the SBP genes were divided into seven subgroups (G1-G7). Interestingly, most members of the same group shared conserved gene structure and motifs as well as gene duplications. This suggests that their functions are redundant highlighting evolutionary relatedness. Identification of the cis-acting elements of the promoter revealed multiple regulatory elements that responded to phytohormone or abiotic stresses. In addition, data from GO annotation indicated that BjuSBPs play a role in biological processes. Further interrogation of the expression of BjuSBPs in different stages of swollen-stem mustard showed spatiotemporal expression patterns. On the other hand, quantitative real-time polymerase chain reaction (qRT-PCR) showed that the expression levels of SBP genes at the development stage correlated with their transcriptome data but treatment with phytohormones affected their expression levels. Our study showed that the SBP-box responds to phytohormone signals and the genes might confer different functions in the development of the mustard plant. Our data lay the foundation for further studies evaluating the regulatory mechanisms of SBP-box family of genes.

“…These variations seem to be controlled at a genetic level by genes of the ABC model. Indeed, the genetic studies in Arachis hypogaea have focused on the regulation of pod formation by MADS-box genes (Li et al 2016). Some of these genes have been cloned by Mei et al (2005), who states that they are related to flower morphogenesis in A. hypogaea.…”

“…On the other hand, the expression of AP2 has been proved to be significantly increased in response to drought (Dang et al 2012). Additionally, the expression profile of A. hypogaea studied by Li et al (2016) showed that SPL proteins are capable of interacting with different coding genes belonging to the MADS-box family. This gene has also been reported to have floral homeotic A function (Theißen et al 2016).…”

From the ancestral bisexual flower (BC model) with radial symmetry to Fabaceae flower with bilateral symmetry and a keel petal, it is critical to understand ABC model because high seed yield and food safety depend on flower bud development. Thus, we summarize the information of the genetic mechanism that explains the identity of the floral organs for Sophoreae, Phaseoleae, Dalbergieae and Genisteae tribes. Moreover, we examine the role of non-coding RNAs on floral development at Cajaninae subtribe, Dalbergieae and Genisteae tribes.
