However, current understanding of the reproductive growth process is relatively limited, especially in the later stages of development. Here we report that <em>OsGAMYBL2,</em> a homologous gene of <em>GAMYB,</em> is required for pollen maturation and germination in rice, and that loss of function of <em>OsGAMYBL2</em> leads to male sterility in rice. We generated three alleles of <em>OsGAMYBL2</em> knockout mutants using CRISPR/Cas9 system, all of them lost fertility when grown in the paddy field. Semi-section and electron microscopy observations revealed that there are no visible morphological changes in the outer and inner surfaces of anther and in the surface of mature pollens between mutants and wild type. However, pollens at late developmental stages exhibited much lighter pollen viability staining and some of them shriveled. <em>In vitro</em> and <em>in vivo</em> germination experiments showed that mutant pollens fail to germinate, leading to abnormal pollen tube formation and subsequent defective pollination. Furthermore, we observed that as compared with high temperature at 30 ​°C, low-temperature at 22 ​°C affects less on <em>osgmybl2</em> fertility. Collectively, we proposed that <em>OsGAMYBL2</em> is likely involved in the regulation of starch accumulation during later pollen development with a thermal-sensitive way, which improves our understanding on the reproductive development in plants.</p></div>","PeriodicalId":74667,"journal":{"name":"Reproduction and breeding","volume":"2 1","pages":"Pages 1-8"},"PeriodicalIF":0.0,"publicationDate":"2022-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2667071222000023/pdfft?md5=4ae013254cbebc4b77ead1db719d73d2&pid=1-s2.0-S2667071222000023-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42754439","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the functions of most PKS III superfamily members in rice (<em>Oryza sativa</em> L.) remain unknown. Here, we identified PKS III genes in rice and performed phylogenetic analysis. This divided the 28 rice PKS III superfamily genes into six subgroups, the chalcone synthase (CHS) group and the CHS-like groups CHSL I–V. These PKS III genes share significant genomic synteny. CHS, CHSL I, and II genes are present in single copies in the rice genome, whereas CHSL III–V are present in gene clusters. The chromosomal regions harboring PKS III genes contain numerous transposable elements, which might underlie the duplication and expansion of the PKS III superfamily. Heatmap analysis indicated that PKS III genes in the same subgroup have similar expression patterns. We knocked out two anther-specific genes (<em>OsPKS1</em> and <em>OsPKS2</em>) from subgroup CHSL II in rice to investigate their roles in male reproduction. The double knockout mutant <em>ospks1</em>/<em>2</em> exhibited severer defects in exine and no-pollen phenotype, which is different from the partially abortive-pollen phenotype of the <em>ospks1</em> and <em>ospks2</em> single mutants. <em>OsPKS1</em> is upregulated in <em>ospks2</em> mutants and <em>OsPKS2</em> is upregulated in <em>ospks1</em> mutants, suggesting that the coordinated activities of OsPKS1 and OsPKS2 are essential for pollen development.

Here, we obtained two new types of allotriploids (3nR₂C and 3nRC₂) by the interploid crossing of female 4nAT with the inbred parents (red crucian carp and common carp, respectively).

The measured DNA content and chromosome numbers suggested that both 3nR₂C and 3nRC₂ were allotriploids with 150 chromosomes. Intermediate characteristics of some morphological traits, such as the body length to body height ratio (BL/BH), were observed in 3nR₂C and 3nRC₂. In contrast to the stage II oocytes in the ovaries of the inbred parents, cystic structures formed by small, underdeveloped oogonia were observed in the two allotriploids. In contrast to the observation of mature spermatids in the testes of the inbred parents, spermatids with irregular shapes that began to degrade and disintegrate were observed in the two allotriploids.
