“…3 F). Previous studies have linked a number of TFs from MADS, MYB, ARF, and GATA gene families to plant male sterility [ 35 – 39 ]. In our study, 86 differentially m 6 A-modified genes may have encoded members of those TF families (i.e., bHLH: 11, B3: 6, WRKY: 5, NAC: 5).…”

“…Plant male sterility is the outcome of a complex process that has been associated with abnormalities in growth substance metabolism, epigenetic regulation, and mitochondrial function [14,35,[53][54][55]. So far, however, the association of m 6 A methylation with male infertility has only been explored in humans [15].…”

Background N6-methyladenosine (m6A) modification is the most abundant type of RNA modification in eukaryotic cells, playing pivotal roles in multiple plant growth and development processes. Yet the potential role of m6A in conferring the trait of male sterility in plants remains unknown. Results In this study, we performed RNA-sequencing (RNA-Seq) and m6A-sequencing (m6A-Seq) of RNAs obtained from the anther tissue of two wolfberry lines: ‘Ningqi No.1’ (LB1) and its natural male sterile mutant ‘Ningqi No.5’ (LB5). Based on the newly assembled transcriptome, we established transcriptome-wide m6A maps for LB1 and LB5 at the single nucleus pollen stage. We found that the gene XLOC_021201, a homolog of m6A eraser-related gene ALKBH10 in Arabidopsis thaliana, was significantly differentially expressed between LB1 and LB5. We also identified 1642 and 563 m6A-modified genes with hypermethylated and hypomethylated patterns, respectively, in LB1 compared with LB5. We found the hypermethylated genes significantly enriched in biological processes related to energy metabolism and lipid metabolism, while hypomethylation genes were mainly linked to cell cycle process, gametophyte development, and reproductive process. Among these 2205 differentially m6A methylated genes, 13.74% (303 of 2205) were differentially expressed in LB1 vis-à-vis LB5. Conclusions This study constructs the first m6A transcriptome map of wolfberry and establishes an association between m6A and the trait of male sterility in wolfberry.

“…Then, the callose is timely degraded by callase, which is produced by sporophytic tapetum, to dissolve the haploid microspore, which further undergoes an asymmetric mitosis, resulting in a generative cell and a vegetative cell. Subsequently, the generative cell undergoes further mitosis to form a tricellular pollen (TCP) with a vegetative cell and two sperm cells [ 33 , 34 , 35 , 36 , 37 , 38 ].…”

Male gametophyte development in plants relies on the functions of numerous genes, whose expression is regulated by transcription factors (TFs), non-coding RNAs, hormones, and diverse environmental stresses. Several excellent reviews are available that address the genes and enzymes associated with male gametophyte development, especially pollen wall formation. Growing evidence from genetic studies, transcriptome analysis, and gene-by-gene studies suggests that TFs coordinate with epigenetic machinery to regulate the expression of these genes and enzymes for the sequential male gametophyte development. However, very little summarization has been performed to comprehensively review their intricate regulatory roles and discuss their downstream targets and upstream regulators in this unique process. In the present review, we highlight the research progress on the regulatory roles of TF families in the male gametophyte development of flowering plants. The transcriptional regulation, epigenetic control, and other regulators of TFs involved in male gametophyte development are also addressed.

“…During the early maize anther development, stamen primordial cells divide and differentiate into four somatic cell layers that encircle sporogenous cells from the exterior to the interior: (i) the outer epidermis (EP), (ii) the endothecium (EN), (iii) the middle layer (ML), and (iv) the tapetum (TA) (Ma, 2005 ; McCormick, 1993 ; Zhang and Yang, 2014 ). The pollen mother cells (PMCs), also referred to as meiocytes, originate from the sporogenous cells and undergo meiosis to produce haploid microspores (Hou et al ., 2022 ). Post‐meiotic anther development requires cooperative interactions between gametophytic (microspores) and somatic cells, particularly with the tapetum cells that directly contacts male gametophytes and provides nutrients for pollen maturation (Wang et al ., 2011 ).…”

SummaryFertile pollen is critical for the survival, fitness, and dispersal of flowering plants, and directly contributes to crop productivity. Extensive mutational screening studies have been carried out to dissect the genetic regulatory network determining pollen fertility, but we still lack fundamental knowledge about whether and how pollen fertility is controlled in natural populations. We used a genome‐wide association study (GWAS) to show that ZmGEN1A and ZmMSH7, two DNA repair‐related genes, confer natural variation in maize pollen fertility. Mutants defective in these genes exhibited abnormalities in meiotic or post‐meiotic DNA repair, leading to reduced pollen fertility. More importantly, ZmMSH7 showed evidence of selection during maize domestication, and its disruption resulted in a substantial increase in grain yield for both inbred and hybrid. Overall, our study describes the first systematic examination of natural genetic effects on pollen fertility in plants, providing valuable genetic resources for optimizing male fertility. In addition, we find that ZmMSH7 represents a candidate for improvement of grain yield.
