Betalains replace anthocyanins as color pigments in most families of Caryophyllales. Unlike anthocyanins, betalains are derived from tyrosine via three enzymatic steps: hydroxylation of L-tyrosine to L-3,4-dihydroxyphenylalanine (L-DOPA; step 1), and conversion of L-DOPA to betalamic acid (step 2),

Ribosome-inactivating proteins (RIPs) are N-glycosidases that remove a specific adenine from the sarcin/ricin loop of the large rRNA, thus arresting protein synthesis at the translocation step. In the present study, a protein termed tobacco RIP (TRIP) was isolated from tobacco (Nicotiana tabacum)

The cDNAs encoding the seed antimicrobial peptides (AMPs) from Mirabilis jalapa (Mj-AMP2) and Amaranthus caudatus (Ac-AMP2) have previously been characterized and it was found that Mj-AMP2 and Ac-AMP2 are processed from a precursor preprotein and preproprotein, respectively [De Bolle et al., Plant

Mirabilis crinkle mosaic virus (MiCMV) was tentatively classified as a new member of the genus Potyvirus in the family Potyviridae in 2019. However, it was considered to be basella rugose mosaic virus based on the sequence similarity of the coat protein (CP) region. In this study, infectious MiCMV

ABSTRACT Ribosome-inactivating proteins (RIPs) are N-glycosidases that remove specific purine residues from the sarcin/ricin (S/R) loop of the large rRNA and arrest protein synthesis at the translocation step. In addition to their enzymatic activity, RIPs have been reputed to be potent antiviral

Begomoviruses are whitefly-transmitted single-stranded DNA viruses that are responsible for considerable economic losses. A begomovirus, alphasatellite and betasatellite were characterized in a Mirabilis jalapa plant exhibiting severe leaf curling and mottling symptoms. The complete viral genome

Several tissues of Mirabilis jalapa L. (Nyctaginaceae) were assayed for inhibition of translation by a rabbit reticulocyte lysate (as a signal of ribosome-inactivating activity) and for adenine DNA glycosylase activity, activities that are both due to the presence of a class of enzymes called

Four o'clock (Mirabilis jalapa) and M. himalaica var. chinensis are members of the family Nyctaginaceae and are widely distributed weeds in Yunnan Province, China. In 2009, mosaic and malformation symptoms were observed on leaves of the four o'clock on the campus of Yunnan Agricultural University

In 2000, circular water-soaked lesions typical of bacterial leaf spot were observed on leaves of collards (Brassica oleracea L. var. viridis) throughout commercial fields in northwest Ohio. Light brown, rectangular, water-soaked lesions were observed on turnip leaves (Brassica rapa L.). Bacterial

A virus from a symptomatic plant of the gymnosperm Welwitschia mirabilis Hook. growing as an ornamental plant in a domestic garden in Western Australia was inoculated to a plant of Nicotiana benthamiana where it established a systemic infection. The complete genome sequence of 9636 nucleotides was

We developed an efficient chimeric promoter, MUASMSCP, with enhanced activity and salicylic acid (SA)/abscisic acid (ABA) inducibility, incorporating the upstream activation sequence (UAS) of Mirabilis mosaic virus full-length transcript (MUAS, -297 to -38) to the 5' end of Mirabilis mosaic virus

A full-length transcript (FLt) promoter fragment was isolated from a genomic clone of mirabilis mosaic virus (MMV), a double-stranded DNA plant pararetrovirus belonging to the caulimovirus family. The boundaries required for maximal promoter expression were defined by 5' and 3' deletion analysis of

ABSTRACT The gram-positive tomato pathogen Clavibacter michiganensis subsp. michiganensis induced a local necrotic response on four-o'clock (Mirabilis jalapa) and tobacco (Nicotiana tabacum) plants. This necrosis response was characteristic of the hypersensitive response (HR). The cell-free culture

The present paper was a part of Ph.D research work, conducted during the year 2014, in which 87 poisonous plants belonging to 54 genera, were collected, documented and preserved in the herbarium of Bannu, Department of Botany UST, Bannu Khyber Pakhtunkwa Pakistan. The plants were identified

Betalains are tyrosine-derived red-violet and yellow pigments, found in plants only of the Caryophyllales order. Although much progress has been made in recent years in the understanding of the betalain biosynthetic process, many questions remain open with regards to several of the proposed steps in
