The Loss of the Inverted Repeat in the Putranjivoid Clade of Malpighiales

et al. 2020

The typical plastid genome (plastome) of photosynthetic angiosperms comprises a pair of Inverted Repeat regions (IRs), which separate a Large Single Copy region (LSC) from a Small Single Copy region (SSC). The independent losses of IRs have been documented in only a few distinct plant lineages. The majority of these taxa show uncommonly high levels of plastome structural variations, while a few have otherwise conserved plastomes. For a better understanding of the function of IRs in stabilizing plastome structure, more taxa that have lost IRs need to be investigated. We analyzed the plastomes of eight species from two genera of the putranjivoid clade of Malpighiales using Illumina paired-end sequencing, the de novo assembly strategy GetOrganelle, as well as a combination of two annotation methods. We found that all eight plastomes of the putranjivoid clade have lost their IR B , representing the fifth case of IR loss within autotrophic angiosperms. Coinciding with the loss of the IR, plastomes of the putranjivoid clade have experienced significant structural variations including gene and intron losses, multiple large inversions, as well as the translocation and duplication of plastome segments. However, Balanopaceae, one of the close relatives of the putranjivoid clade, exhibit a relatively conserved plastome organization with canonical IRs. Our results corroborate earlier reports that the IR loss and additional structural reorganizations are closely linked, hinting at a shared mechanism that underpins structural disturbances.

“…The family Malvaceae, commonly referred to as mallows, is comprised of >4225 species of annual and perennial plants [ 39 , 40 ]. Members of this family are distributed worldwide, and occur in temperate, tropical and subtropical regions [ 40 , 41 ]. Some species are important crops, such as cotton and okra [ 41 ]; others are grown as ornamentals or for medicinal purposes; and others are considered invasive weeds, e.g., Abutilon spp., Sida spp.…”

Weed-infecting viruses in a tropical agroecosystem present different threats to crops and evolutionary histories

et al. 2021

In the Caribbean Basin, malvaceous weeds commonly show striking golden/yellow mosaic symptoms. Leaf samples from Malachra sp. and Abutilon sp. plants with these symptoms were collected in Hispaniola from 2014 to 2020. PCR tests with degenerate primers revealed that all samples were infected with a bipartite begomovirus, and sequence analyses showed that Malachra sp. plants were infected with tobacco leaf curl Cuba virus (TbLCuCV), whereas the Abutilon sp. plants were infected with a new bipartite begomovirus, tentatively named Abutilon golden yellow mosaic virus (AbGYMV). Phylogenetic analyses showed that TbLCuCV and AbGYMV are distinct but closely related species, which are most closely related to bipartite begomoviruses infecting weeds in the Caribbean Basin. Infectious cloned DNA-A and DNA-B components were used to fulfilled Koch’s postulates for these diseases of Malachra sp. and Abutilon sp. In host range studies, TbLCuCV also induced severe symptoms in Nicotiana benthamiana, tobacco and common bean plants; whereas AbGYMV induced few or no symptoms in plants of these species. Pseudorecombinants generated with the infectious clones of these viruses were highly infectious and induced severe symptoms in N. benthamiana and Malachra sp., and both viruses coinfected Malachra sp., and possibly facilitating virus evolution via recombination and pseudorecombination. Together, our results suggest that TbLCuCV primarily infects Malachra sp. in the Caribbean Basin, and occasionally spills over to infect and cause disease in crops; whereas AbGYMV is well-adapted to an Abutilon sp. in the Dominican Republic and has not been reported infecting crops.

Klainedoxa gabonensis Pierre ex Engl. is an important tropical tree species. In this study, its complete plastome sequence was determined. This is the first reported complete plastome sequence in the family Irvingiaceae. The plastome is totally 160,118 bp in length, containing a pair of 26,963-bp-long inverted repeat regions (IRs), a large single copy region of 88,157 bp, and a small single copy region of 18,035 bp. A total of 112 unique genes were identified in K. gabonensis plastome, of which 78 are protein-coding genes, 30 are tRNA genes, and four are rRNA genes. Phylogenetic analysis confirmed the close relationship between K. gabonensis and Irvingia malayana.
