Abstract
KEY MESSAGE Overexpression of JcGAST1 promotes plant growth but inhibits pistil development. The pyrimidine box and CGTCA motif of the JcGAST1 promoter were responsible for the GA and MeJA responses. Members of the gibberellic acid-stimulated Arabidopsis (GASA) gene family play roles in plant growth and development, particularly in flower induction and seed development. However, there is still relatively limited knowledge of GASA genes in Jatropha curcas. Herein, we identified a GASA family gene from Jatropha curcas, namely, JcGAST1, which encodes a protein containing a conserved GASA domain. Sequence alignment showed that the JcGAST1 protein shares 76% sequence identity and 80% sequence similarity with SlGAST1. JcGAST1 had higher expression and protein levels in the female flowers than in the male flowers. Overexpression of JcGAST1 in tobacco promotes plant growth but inhibits pistil development. JcGAST1 expression was upregulated by GA and downregulated by MeJA. Promoter analysis indicated that the pyrimidine box and CGTCA motif were the GA- and MeJA-responsive elements of the JcGAST1 promoter. Using a Y1H screen, six transcription factors were found to interact with the pyrimidine box, and three transcription factors were found to interact with the CGTCA motif. Overall, the results of this study improve our understanding of the JcGAST1 gene and provide useful information for further studies.

[PMID: 36211058 PMCID: PMC9535702 DOI: 10.1021/acsomega.2c02749] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/03/2022] [Accepted: 09/06/2022] [Indexed: 06/16/2023]
Abstract
The herbaceous peony (Paeonia lactiflora Pall.) is a traditional rare flower in China, and production of its cut flowers has developed gradually in many places of the world. However, the inflorescence stems of some P. lactiflora cultivars have such low mechanical strength that the cut flower production was severely restricted. To better understand the causes of this problem from a protein expression level, two P. lactiflora cultivars with different inflorescence stem mechanical strengths were analyzed by two-dimensional electrophoresis and MALDI-TOF/MS. More than 1700 clear protein spots were detected, 53 of which varied significantly. Moreover, 23 of the differentially expressed proteins were identified and confirmed and are involved in various biological processes such as metabolism, protein biosynthesis and transport, signal transduction, and defensive response. Especially, cinnamyl alcohol dehydrogenase (CAD) and xyloglucan endotransglucosylase/hydrolase (XTH) were strongly connected to the inflorescence stem mechanical strength in P. lactiflora.

BMC PLANT BIOLOGY 2021; 21:289. [PMID: 34167466 PMCID: PMC8223347 DOI: 10.1186/s12870-021-03067-6] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/04/2021] [Accepted: 05/17/2021] [Indexed: 05/24/2023]
Abstract
BACKGROUND Blueberry (Vaccinium spp.) is characterized by the production of berries that are smaller than most common fruits, and the underlying mechanisms of fruit size in blueberry remain elusive. V. corymbosum 'O'Neal' and 'Bluerain' are commercial southern highbush blueberry cultivars with large- and small-size fruits, respectively, which mature 'O'Neal' fruits are 1 ~ 2-fold heavier than those of 'Bluerain'. In this study, the ontogenetical patterns of 'O'Neal' and 'Bluerain' hypanthia and fruits were compared, and comparative transcriptomic analysis was performed during early fruit development. RESULTS V. corymbosum 'O'Neal' and 'Bluerain' hypanthia and fruits exhibited intricate temporal and spatial cell proliferation and expansion patterns. Cell division before anthesis and cell expansion after fertilization were the major restricting factors, and outer mesocarp was the key tissue affecting fruit size variation among blueberry genotypes. Comparative transcriptomic and annotation analysis of differentially expressed genes revealed that the plant hormone signal transduction pathway was enriched, and that jasmonate-related TIFYs genes might be the key components orchestrating other phytohormones and influencing fruit size during early blueberry fruit development. CONCLUSIONS These results provided detailed ontogenetic evidence for determining blueberry fruit size, and revealed the important roles of phytohormone signal transductions involving in early fruit development. The TIFY genes could be useful as markers for large-size fruit selection in the current breeding programs of blueberry.
