“…Pollen cell wall development is a crucial part of pollen production, and an abnormal pollen cell wall may be associated with male sterility in plants ( Li et al, 2006 ; Ma et al, 2007 ; Wijeratne et al, 2007 ; Wei et al, 2013a ; Hu et al, 2016 ; Xu et al, 2017 ; Zhou et al, 2017 ; Chen et al, 2018 , 2019 ; Hamid et al, 2019 ; Nugent et al, 2019 ; Sutthinon et al, 2019 ; Mondol et al, 2020 ). Some genes controlling pollen development have been identified and cloned ( Shi et al, 2011 ), including DMD1 ( Ren et al, 2020 ), DPW2 ( Xu et al, 2017 ), and DPW3 ( Mondol et al, 2020 ).…”

Cytoplasmic male sterility (CMS) is an important plant characteristic for exploiting heterosis to enhance crop traits during breeding. However, the CMS regulatory network remains unclear in plants, even though researchers have attempted to isolate genes associated with CMS. In this study, we performed high-throughput sequencing and degradome analyses to identify microRNAs (miRNAs) and their targets in a soybean CMS line (JLCMS9A) and its maintainer line (JLCMS9B). Additionally, the differentially expressed genes during reproductive development were identified using RNA-seq data. A total of 280 miRNAs matched soybean miRNA sequences in miRBase, including mature miRNAs and pre-miRNAs. Of the 280 miRNAs, 30, 23, and 21 belonged to the miR166, miR156, and miR171 families, respectively. Moreover, 410 novel low-abundant miRNAs were identified in the JLCMS9A and JLCMS9B flower buds. Furthermore, 303 and 462 target genes unique to JLCMS9A and JLCMS9B, respectively, as well as 782 common targets were predicted based on the degradome analysis. Target genes differentially expressed between the CMS line and the maintainer line were revealed by an RNA-seq analysis. Moreover, all target genes were annotated with diverse functions related to biological processes, cellular components, and molecular functions, including transcriptional regulation, the nucleus, meristem maintenance, meristem initiation, cell differentiation, auxin-activated signaling, plant ovule development, and anther development. Finally, a network was built based on the interactions. Analyses of the miRNA, degradome, and transcriptome datasets generated in this study provided a comprehensive overview of the reproductive development of a CMS soybean line. The data presented herein represent useful information for soybean hybrid breeding. Furthermore, the study results indicate that miRNAs might contribute to the soybean CMS regulatory network by modulating the expression of CMS-related genes. These findings lay the foundation for future studies on the molecular mechanisms underlying soybean CMS.

“…This typical structural pattern can be altered by deviations in the developmental pathway (Twell et al 1998;Dunwell 2010) and loss of reproductive potential, usually leading to male sterility to varying degrees. Alterations in the programmed cell death (PCD) in tapetum is an intrinsic phenomenon widely related to male sterility (Li et al 2006;González-Melendi et al 2008;Hu et al 2014;Haddad et al 2019;Sutthinon et al 2019), and often associated with cytoplasmic male sterility (CMS), which combined generate a total or partial sterility in the developing anthers. In such cases, the alterations usually result in unviable free microspores and, consequently, in pollen sterility and abortion (Haddad et al 2019;Sutthinon et al 2019).…”

In such cases, the alterations usually result in unviable free microspores and, consequently, in pollen sterility and abortion (Haddad et al 2019;Sutthinon et al 2019). Other factors such as stress, caused by high temperatures and low water availability (Ji et al 2010; De Storme and Geelen 2013), or biotic factors such as hybridization (Chaturvedi et al 1990(Chaturvedi et al , 1999Bohra et al 2016), or cytomixis (Haroun 1995;Kumar and Srivastava 2009;Kumar et al 2010;Singhal and Kaur 2011) are also potentials causes for deviations and interruptions in pollen development that may not always lead to abortions.…”

“…Surprisingly, they find that the pollen grains (the male spores) develop and mature completely normally, which means that the reason for the male sterility must be searched for either in the release of the spores (so called anther dehiscence) or in the development of the resulting macrogametophyte (the pollen tube). Also, the work by Sutthinon et al (2019) in the current issue is motivated by the need to understand male sterility, this case for mangosteen. This important tropical crop is endowed with a quite mysterious sexuality.…”
