“…A shorter pollen longevity has been reported for the following rice mutants: glossy1-4 (osgl1-4), humidity-sensitive genetic male sterility1 (hms1) and oxidosqualene cyclases 12/poaceatapetol synthase 1 (ososc12/ospts1) ( Table 1) [42][43][44]. The defects in the pollen wall, particularly in the pollen coat, observed in these mutants result in excessive fast dehydration, leading to humidity-sensitive male sterility [42][43][44]. The pollen coat fills the cavities of the pollen exine and protects the male gametophyte from dehydration in rice.…”

Understanding the behavior of pollen during pollination is important for food security in the future. The elucidation of pollen development and growth regulation largely relies on the study of the dicotyledonous model plant Arabidopsis thaliana. However, rice (Oryza sativa) pollen exhibits different characteristics to that of Arabidopsis. The latter undergoes programmed dehydration and withstands adverse environmental conditions, whereas rice pollen is sensitive to desiccation. Moreover, the short longevity of rice pollen significantly hampers hybrid seed production. Although the “omics” data for mature rice pollen have been accumulated, few genes that control pollination and pollen hydration have been identified. Therefore, to facilitate future studies, it is necessary to summarize the developmental processes involved in pollen production in rice and to consolidate the underlying mechanisms discovered in previous studies. In this review, we describe the pollen developmental processes and introduce gametophytic mutants, which form defective pollen in Arabidopsis and rice. In addition, we discuss the perspectives on the research on pollen longevity, adhesion and hydration.

“…Two-line HR technology is regulated by environmental alterations such as photoperiod and/or temperature and humidity conditions and it also termed as an environmental sensitive-genic-male-sterility (EGMS) system. Therefore, we are reporting that the EGMS system can be categorized as the photo-sensitive-genic-male-sterility (PGMS) system, temperature-sensitive-genic-male-sterility (TGMS) system, and humidity-sensitive-genic-male-sterility (HGMS) system [ 41 , 42 ]. The two-line HR technology gained popularity due to simplicity in creating sterile-rice lines by PGMS, TGMS, and HGMS systems and fertility can be restored via crossing any fertile rice-line and there is no need for a specific restorer-rice line as compared to three-line HR technology.…”

The significance of the climate change may involve enhancement of plant growth as well as utilization of the environmental alterations in male fertility (MF) regulation via male sterility (MS) systems. We described that MS systems provide a fundamental platform for improvement in agriculture production and have been explicated for creating bulk germplasm of the two-line hybrids (EGMS) in rice as compared to the three-line, to gain production sustainability and exploit its immense potential. Environmental alterations such as photoperiod and/or temperature and humidity regulate MS in EGMS lines via genetic and epigenetic changes, regulation of the noncoding RNAs, and RNA-metabolism including the transcriptional factors (TFs) implication. Herein, this article enlightens a deep understanding of the molecular control of MF in EGMS lines and exploring the regulatory driving forces that function efficiently during plant adaption under a changing environment. We highlighted a possible solution in obtaining more stable hybrids through apomixis (single-line system) for seed production.

“…In the two-line hybrid technology, EGMS lines are used as the male sterile lines and maintainer lines under contrary environmental conditions, and have the advantage of broad restorer lines. The EGMS lines include photoperiod-sensitive genic male sterility (PGMS) lines, thermo-sensitive genic male sterility (TGMS) lines, and the recently reported humidity-sensitive genic male sterility (HGMS) lines [5]. In upland cotton, CCRI9106, a PGMS mutant isolated from CCRI040029 was controlled by one pair of recessive genes, and showed male sterile under long-day conditions and fertile under short-day conditions [6,7].…”

“…Recently, a HGMS line is isolated in rice and the corresponding gene (HMS1) is characterized as a putative β-ketoacyl-CoA synthase (KCS). The hsm1 mutants show abnormal anther cuticle without white crystals and signi cant reduction of bacula and tryphine in pollen wall [5]. A glossy family protein, OsGL1-4, is require for the synthesis of very long chain alkanes, and is essential to the pollen adhesion and hydration.…”

Background: Male sterility is a simple and efficient pollination control system that is widely exploited in hybrid breeding. In upland cotton, CCRI9106, a photosensitive genetic male sterile (PGMS) mutant isolated from CCRI040029, was reported of great advantages to cotton heterosis. However, little information concerning the male sterility of CCRI9106 is known. Here, comparative transcriptome analysis of CCRI9106 (the mutant, MT) and CCRI040029 (the wild type, WT) anthers in Anyang (long-day, male sterile condition to CCRI9106) was performed to reveal the potential male sterile mechanism of CCRI9106.Results: Light and electron microscopy revealed that the male sterility phenotype of MT was mainly attributed to irregularly exine, lacking tryphine and immature anther cuticle. Based on the cytological characteristics of MT anthers, anther RNA libraries (18 in total) of tetrad (TTP), late uninucleate (LUNP) and binucleate (BNP) stages in MT and WT were constructed for transcriptomic analysis, therefore revealing a total of 870,4 differentially expressed genes (DEGs). By performing gene expression pattern analysis and protein-protein interaction (PPI) networks construction, we found down-regulation of DEGs, which enriched by the lipid biosynthetic process and the synthesis pathways of several types of secondary metabolites such as terpenoids, flavonoids and steroids, may crucial to the male sterility phenotype of MT, and resulting in the defects of anther cuticle and tryphine, even the irregularly exine. Furthermore, several lipid-related genes together with ABA-related genes and MYB transcription factors were identified as hub genes via weighted gene co-expression network analysis (WGCNA). Additionally, the ABA content of MT anthers was reduced across all stages when compared with WT anthers. At last, genes related to the formation of anther cuticle and tryphine could activated in MT under short-day condition.Conclusions: We propose that the down-regulation of genes related to the assembly of anther cuticle and tryphine may lead to the male sterile phenotype of MT, and MYB transcription factors together with ABA played key regulatory roles in these processes. The conversion of fertility in different photoperiods may closely relate to the functional expression of these genes. These findings contribute to elucidate the mechanism of male sterility in upland cotton.
