FRONTIERS IN PLANT SCIENCE 2023; 14:1201486. [PMID: 37457333 PMCID: PMC10340533 DOI: 10.3389/fpls.2023.1201486] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 04/06/2023] [Accepted: 06/09/2023] [Indexed: 07/18/2023]
Abstract
Pogostemon cablin is a well-known protected species widely used in medicine and spices, however the underlying molecular mechanisms and metabolite dynamics of P. cablin flower development remain unclear due to the difficulty in achieving flowering in this species. A comparison of the transcriptome and widely targeted metabolome during P. cablin flower development was first performed in this study. Results showed that a total of 13,469 differentially expressed unigenes (DEGs) and 371 differentially accumulated metabolites (DAMs) were identified. Transcriptomic analysis revealed that the DEGs were associated with starch and sucrose metabolism, terpenoid biosynthesis and phenylpropanoid biosynthesis. Among these DEGs, 75 MIKC-MADS unigenes were associated with the development of floral organs. Gibberellins (GAs), auxin, and aging signaling might form a cross-regulatory network to regulate flower development in P. cablin. According to the metabolic profile, the predominant DAMs were amino acids, flavonoids, terpenes, phenols, and their derivatives. The accumulation patterns of these predominant DAMs were closely associated with the flower developmental stage. The integration analysis of DEGs and DAMs indicated that phenylpropanoids, flavonoids, and amino acids might be accumulated due to the activation of starch and sucrose metabolism. Our results provide some important insights for elucidating the reproductive process, floral organ, and color formation of P. cablin flowers at the molecular level. These results will improve our understanding of the molecular and genetic mechanisms involved in the floral development of P. cablin.

Sidharthan VK, Rajeswari V, Vanamala G, Baranwal VK. Revisiting the amalgaviral landscapes in plant transcriptomes expands the host range of plant amalgaviruses. Virology 2022; 577:65-73. [PMID: 36308887 DOI: 10.1016/j.virol.2022.10.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/03/2022] [Revised: 10/09/2022] [Accepted: 10/16/2022] [Indexed: 11/19/2022]
Abstract
Plant amalgaviruses are monopartite, double-stranded RNA viruses, capable of vertical transmission through seeds. An attempt to revisit plant transcriptome-assembled contigs for amalgaviral sequences identified 40 putative novel amalgaviruses in 35 plant species, nearly doubling the number of plant amalgaviruses. Of the 35 plant species, 33 are reported to host amalgaviruses for the first time, including a pteridophytic and two gymnospermic species. Coding-complete genomes of all identified viruses were recovered and the putative +1 programmed ribosomal frameshift (PRF) sites were determined. Genomes of 35 identified amalgaviruses contained the conserved +1 PRF motif 'UUU_CGN', while variant versions were predicted in five genomes. Phylogenetic analysis grouped pteridophyte- and gymnosperm-infecting amalgaviruses together in divergent sub-clades while few of the related angiosperm-infecting amalgaviruses infect members of the same plant family, reiterating the co-evolution of plant amalgaviruses and their hosts. The current study paves way for further studies on understanding biological properties of identified viruses.

Abstract
A nomenclatural and taxonomic treatment of the name Melastoma candidum f. albiflorum (Melastomataceae) is presented. A lectotype is designated for this name, with an updated morphological description based on fresh material. The name Melastoma candidum f. albiflorum is proposed as a heterotypic synonym of Melastoma candidum.
