Hydrogen peroxide in micropropagation of Lilium: A comparison with a traditional methodology [PDF]

, 2006
The micropropagation of Lilium longiflorum requires adequate equipment which may not be afforded by small laboratories or producers. In this work we compared traditional methodology with a protocol that included easily available elements to sterilize ...

Unstable anthocyanin pigmentation in Streptocarpus sect. Saintpaulia (African violet) is due to transcriptional selectivity of a single MYB gene

New Phytologist, Volume 247, Issue 3, Page 1426-1444, August 2025.
Summary Saintpaulia (African violet) pigmentation is notoriously unstable and sometimes forms white stripes, particularly following passage through tissue culture. White‐striped petals were thought to be due to periclinal chimeras, but we confirmed that white stripes result from epigenetic regulation rather than periclinal chimeras based on the flower ...

Seed germination and in vitro regeneration of the African medicinal and pesticidal plant, Bobgunnia madagascariensis [PDF]

, 2011
Propagation of the medicinal and pesticidal tree, Bobgunnia madagascarensis is difficult due to poor and erratic germination of its seeds and slow growth of its seedlings. This study involved two separate experiments.

COmapper: high‐resolution mapping of meiotic crossovers by long‐read sequencing in Arabidopsis

New Phytologist, Volume 247, Issue 4, Page 1942-1957, August 2025.
Summary Meiotic crossovers rearrange existing genetic variation between homologous chromosomes, profoundly affecting genomic diversity. Crossovers are typically constrained to one to three events per chromosome pair, and their distribution is shaped by chromatin accessibility and DNA polymorphisms.

Root Hair Development Is Suppressed by Long‐Term Mild Heat Through Down‐Regulation of RHD6 and RHD6‐like Genes

Plant, Cell &Environment, Volume 48, Issue 8, Page 5861-5873, August 2025.
ABSTRACT Roots located in the upper soil layers are prone to experiencing high temperatures. Despite their importance for water and nutrient absorption, little is known about the effect of high temperature on root hairs. Here, we found that exposure of Arabidopsis thaliana seedlings to long‐term mild heat suppressed root hair initiation.

A Holistic Investigation of Arabidopsis Proteomes Altered in Chloroplast Biogenesis and Retrograde Signalling Identifies PsbO as a Key Regulator of Chloroplast Quality Control

Plant, Cell &Environment, Volume 48, Issue 8, Page 6373-6396, August 2025.
ABSTRACT Communication between the diverse compartments of plant cells relies on an intricate network of molecular interactions that orchestrate organellar development and adaptation to environmental conditions. Plastid‐to‐nucleus signalling pathways play a key role in relaying information from developing, mature, and damaged or disintegrating ...
