BLADE‐ON‐PETIOLE Genes Enable Genetic Bottleneck Mitigation Through Cross‐Species Repurposing of Floral Persistence Traits

Advanced Science, Volume 13, Issue 32, 9 June 2026.
This study shows that BLADE‐ON‐PETIOLE (BOP) proteins regulate floral abscission and senescence in tomato by interacting with TFAM1 to form transcriptional condensates controlling the ARABIDOPSIS THALIANA HOMEOBOX GENE 1 (ATH1)‐mediated abscission pathway.

The impacts of biological invasions

Biological Reviews, Volume 101, Issue 3, Page 1255-1310, June 2026.
ABSTRACT The Anthropocene is characterised by a continuous human‐mediated reshuffling of the distributions of species globally. Both intentional and unintentional introductions have resulted in numerous species being translocated beyond their native ranges, often leading to their establishment and subsequent spread – a process referred to as biological

Exploring Floristic Diversity and Medicinal Plant Uses in Venda, Limpopo, South Africa

Feddes Repertorium, Volume 137, Issue 2, June 2026.
ABSTRACT Plants have been an important source of medicine for thousands of years. To better understand the current diversity and usage of medicinal plants, floristic studies are essential. This report documents an expedition conducted in the Venda region of Limpopo, South Africa. The study was carried out in Shanzha and surrounding villages, as well as

A source-sink model explains the difference in the metabolic mechanism of mechanical damage to young and senescing leaves in Catharanthus roseus

BMC Plant Biology, 2021
Background Mechanical damage is an unavoidable threat to the growth and survival of plants. Although a wound to senescing (lower) leaves improves plant vitality, a wound to younger (upper) leaves often causes damage to or death of the whole plant. Source-

A Malectin‐Like Receptor Kinase and Bacterial Motility Shape Tissue‐Specific Maize–Xanthomonas vasicola Interactions

Molecular Plant Pathology, Volume 27, Issue 6, June 2026.
Dual RNA‐seq reveals that ZmCrRLK1L19 and bacterial motility drive tissue‐specific maize–Xanthomonas interactions, distinguishing mesophyll from vascular colonization strategies. ABSTRACT Understanding how pathogens infect different tissue types and how plants mount tissue‐specific defences against bacterial pathogens is critical for improving disease ...

The Structure of Carboxyl Methyltransferase Provides Insights Into the Substrate Specificity and Divergent Evolution of Iridoid

Plant Biotechnology Journal, Volume 24, Issue 6, Page 3708-3722, June 2026.
ABSTRACT Iridoids constitute a prominent class of plant‐specialised metabolites, with carbocyclic iridoids (e.g., geniposide) and secoiridoids (e.g., loganin) diverging early in their biosynthetic pathways. This divergence is marked by substrate‐specific carboxyl methyltransferases—GjGAMT and CrLAMT—that catalyse the decisive methylation step in ...
