Genome-Wide Analysis of the MADS-box Gene Family and Expression Analysis during Anther Development in Salvia miltiorrhiza

International Journal of Molecular Sciences (2023)

Songyue Chai Kexin Li Xuexue Deng Long Wang Yuanyuan Jiang

MADS-box genes constitute a large family of transcription factors that play important roles in plant growth and development. However, our understanding of MADS-box genes involved in anther development and male sterility in Salvia miltiorrhiza is still limited. In this study, 63 MADS-box genes were identified from the genome of the male sterility ecotype Sichuan S. miltiorrhiza (S. miltiorrhiza_SC) unevenly distributed among eight chromosomes. Phylogenetic analysis classified them into two types and 17 subfamilies. They contained 1 to 12 exons and 10 conserved motifs. Evolution analysis showed that segmental duplication was the main force for the expansion of the SmMADS gene family, and duplication gene pairs were under purifying selection. Cis-acting elements analysis demonstrated that the promoter of SmMADS genes contain numerous elements associated with plant growth and development, plant hormones, and stress response. RNA-seq showed that the expression levels of B-class and C-class SmMADS genes were highly expressed during anther development, with SmMADS11 likely playing an important role in regulating anther development and male fertility in S. miltiorrhiza_SC. Overall, this study provides a comprehensive analysis of the MADS-box gene family in S. miltiorrhiza, shedding light on their potential role in anther development and male sterility.

Separable regulation of POW1 in TAF2-mediated grain development and BR-mediated leaf angle formation in rice

bioRxiv (Cold Spring Harbor Laboratory) (2019)

Li Zhang Ruci Wang Yueming Wang Yufang Xu Shuang Fang

ABSTRACT Leaf angle is one of the key factors determining rice plant architecture. However, improvement of the leaf angle appears to be unsuccessful in practical breeding because of the simultaneous occurrence of unfavorable traits such as grain size reduction. In this study, we identified the pow1 ( p ut o n w eight 1 ) mutant with enlarged grain size and leaf angle, typical brassinosteroid (BR)-related phenotypes caused by excessive cell proliferation and cell expansion. We show that POW1 encodes a novel protein functioning in grain size regulation by repressing the transcription activity of the interacting protein TAF2, a highly conserved member of the transcription initiation complex TFIID. Loss of function of POW1 increases the phosphorylation of OsBZR1 and decreases the inhibitory effect of OsBZR1 on the transcription of BR biosynthesis genes OsDWARF4 ( D4 ) and D11 , thus participates in BR-mediated leaf angle regulation. The separable functions of POW1 in grain size and leaf angle control provide a promising strategy to design high-yielding varieties in which both traits would be favorably developed, i.e., compact plant architecture and increased grain size, thus would promote the high-yield breeding a step forward in rice.

Daphnipaxianines A–D, Alkaloids from Daphniphyllum paxianum

Journal of Natural Products (2007)

Shu‐Zhen Mu Chun‐Shun Li Hong‐Ping He Ying‐Tong Di Ye Wang

Four new Daphniphyllum alkaloids, daphnipaxianines A–D (1–4), along with six known ones, have been isolated from the leaves and fruits of Daphniphyllum paxianum. Daphnipaxianines A and B (1, 2), a pair of epimers differing at C-10, are the first caliciphylline A type Daphniphyllum alkaloids with a Δ9(15)-unsaturated cyclic ketone unit, and daphnipaxianine D (4) is the first yuzurine-type Daphniphyllum alkaloid containing a hexacyclic ring system. The structures of these alkaloids were characterized by spectroscopic methods, especially 2D NMR techniques. A single-crystal X-ray diffraction analysis was used to confirm the structure of 1.

Short and Solid Culm/RFL/APO2 for culm development in rice

The Plant Journal (2017)

Juan Wang Ruci Wang Yueming Wang Li Zhang Li Zhang

Summary The culm development of rice is characterized by elongation and medullary cavity ( MC ) formation, which are determined by node formation meristem and residual meristem, respectively. Although many factors have been shown to affect culm elongation, molecules involved in MC formation remained to be identified. In this study, we show that a point mutation in SHORT and SOLID CULM ( SSC ), the rice homologue of Arabidopsis LFY , resulted in plants with drastically reduced culm length and completely abolished MC formation. Analysis of transgenic plants with moderately enhanced SSC expression revealed significant decreases in plant height and MC size in contrast to slight changes in heading date, indicating that the culm developmental process is much more tightly monitored by the gene. Transcriptomic analysis revealed the differential expression of knotted‐1 like homeobox ( KNOX ) protein genes and gibberellin ( GA ) metabolic genes in the ssc mutant background, and most of the genes contained well‐conserved LFY ‐binding cis ‐elements that could be effectively recognized by SSC . Genetic analysis found that the reduced culm length of the mutant could be largely rescued by the GA ‐accumulating mutation eui , whereas MC formation remained unchanged in the double mutant plants. Taken together, our results suggest that SSC affects culm elongation mainly through maintaining GA homeostasis, while functions in MC formation by mediating residual meristem activity possibly via the KNOX pathway. The present study provides a potential strategy for improving the culm morphology and plant architecture in rice by manipulating SSC and/or its downstream components.

Genome-Wide Analysis of the TCP Transcription Factor Genes in Dendrobium catenatum Lindl.

International Journal of Molecular Sciences (2021)

Li Zhang Cheng Li Danni Yang Yuhua Wang Yongping Yang

Teosinte branched1/cycloidea/proliferating cell factor (TCP) gene family members are plant-specific transcription factors that regulate plant growth and development by controlling cell proliferation and differentiation. However, there are no reported studies on the TCP gene family in Dendrobium catenatum Lindl. Here, a genome-wide analysis of TCP genes was performed in D. catenatum, and 25 TCP genes were identified. A phylogenetic analysis classified the family into two clades: Class I and Class II. Genes in the same clade share similar conserved motifs. The GFP signals of the DcaTCP-GFPs were detected in the nuclei of tobacco leaf epidermal cells. The activity of DcaTCP4, which contains the miR319a-binding sequence, was reduced when combined with miR319a. A transient activity assay revealed antagonistic functions of Class I and Class II of the TCP proteins in controlling leaf development through the jasmonate-signaling pathway. After different phytohormone treatments, the DcaTCP genes showed varied expression patterns. In particular, DcaTCP4 and DcaTCP9 showed opposite trends after 3 h treatment with jasmonate. This comprehensive analysis provides a foundation for further studies on the roles of TCP genes in D. catenatum.

Separable regulation of POW1 in grain size and leaf angle development in rice

Plant Biotechnology Journal (2021)

Li Zhang Ruci Wang Yide Xing Yufang Xu Dunping Xiong

Leaf angle is one of the key factors that determines rice plant architecture. However, the improvement of leaf angle erectness is often accompanied by unfavourable changes in other traits, especially grain size reduction. In this study, we identified the pow1 (put on weight 1) mutant that leads to increased grain size and leaf angle, typical brassinosteroid (BR)-related phenotypes caused by excessive cell proliferation and cell expansion. We show that modulation of the BR biosynthesis genes OsDWARF4 (D4) and D11 and the BR signalling gene D61 could rescue the phenotype of leaf angle but not grain size in the pow1 mutant. We further demonstrated that POW1 functions in grain size regulation by repressing the transactivation activity of the interacting protein TAF2, a highly conserved member of the TFIID transcription initiation complex. Down-regulation of TAF2 rescued the enlarged grain size of pow1 but had little effect on the increased leaf angle phenotype of the mutant. The separable functions of the POW1-TAF2 and POW1-BR modules in grain size and leaf angle control provide a promising strategy for designing varieties with compact plant architecture and increased grain size, thus promoting high-yield breeding in rice.
