Root-Associated Microbiomes, Growth and Health of Ornamental Geophytes Treated with Commercial Plant Growth-Promoting Products.

The microbial community inhabiting a plant's root zone plays a crucial role in plant health and protection. To assess the ability of commercial plant growth-promoting products to enhance the positive effects of this environment, two products containing beneficial soil bacteria and a product containing plant extracts were tested on and . The products were tested in two different growing media: a soil and a soilless medium.

Ecological adaptations influence the susceptibility of plants in the genus Zantedeschia to soft rot Pectobacterium spp.

Soft rot disease caused by Pectobacterium spp. is responsible for severe agricultural losses in potato, vegetables, and ornamentals. The genus Zantedeschia includes two botanical groups of tuberous ornamental flowers that are highly susceptible to the disease.

Host Specificity and Differential Pathogenicity of Strains from Dicot and Monocot Hosts.

Recent phylogenetic studies have transferred certain isolates from monocot plants previously included in the heterogeneous group of (Pc) to a species level termed . The specificity of associated infections had received less attention, and may be of high scientific and economic importance. Here, we have characterized differential responses of isolates from potato (WPP14) and calla lily (PC16) on two typical hosts: var.

Transcriptome Profiling of Leaves and Flowers to Identify Key Carotenoid Genes for CRISPR Gene Editing.

is a popular ornamental monocot native to South Africa with flower colors ranging from pure white to deep orange. Gene editing based on the CRISPR/Cas9 system has recently been shown to hold potential for color improvement in ornamental flower crops. To apply this approach to color manipulation, genomic or transcriptomic data must first be collected.

SELENOPROTEIN O is a chloroplast protein involved in ROS scavenging and its absence increases dehydration tolerance in Arabidopsis thaliana.

The evolutionary conserved family of Selenoproteins performs redox-regulatory functions in bacteria, archaea and eukaryotes. Among them, members of the SELENOPROTEIN O (SELO) subfamily are located in mammalian and yeast mitochondria, but their functions are thus far enigmatic. Screening of T-DNA knockout mutants for resistance to the proline analogue thioproline (T4C), identified mutant alleles of the plant SELO homologue in Arabidopsis thaliana.
