Modulating ascorbic acid levels to optimize somatic embryogenesis in Picea abies (L.) H. Karst. Insights into oxidative stress and endogenous phytohormones regulation

Frontiers in Plant Science
Global warming has adversely affected Picea abies (L.) H. Karst. forests in Europe, prompting the need for innovative forest-breeding strategies. Somatic embryogenesis (SE) offers promise but requires protocol refinement.

Rational reduction of a sorghum SynCom that preserves growth promotion reveals flavonoid‐mediated plant–microbe interactions

New Phytologist, Volume 251, Issue 6, Page 3507-3521, September 2026.
Synthetic community complexity reduction designs. Summary Plant growth is influenced by the composition of its associated microbiome. The inherent complexity and functional redundancy of natural plant microbiomes present a formidable barrier to understanding the myriad biological interactions therein.

Brassinosteroids, gibberellins and light-mediated signalling are the three-way controls of plant sprouting.

, 2012
International audienceThe steroid hormones found in plants, the brassinosteroids, were originally genetically identified about 15 years ago as critical regulators of seedling photomorphogenesis.

MYB Factors: Hubs of Plant Stress and Hormone Crosstalk

Plant Biotechnology Journal, Volume 24, Issue 9, Page 5201-5223, September 2026.
ABSTRACT MYB transcription factors function as main regulatory hubs that integrate environmental signals with multi‐hormonal pathways to synchronize plant growth, metabolism and stress responses. This review delineates the regulatory roles of MYB in the signalling pathway of salicylic acid, jasmonic acid, ethylene and abscisic acid signalling.

Role of brassinosteroids in plant response to drought stress

, 2011
Brassinosteroids are steroid phytohormones with a wide range of effects. They improve survivance of plants exposed to drought stress, increase their resistence and yield therethrough.

USE OF ANALYTICAL METHODS TO ASSESS THE POTENTIAL PRESENCE OF BRASSINOSTEROIDS IN CATHARANTHUS ROSEUS L. CARPEL EXUDATES

, 2015
Despite being found in low concentration in plant tissue, brassinosteroids play a significant role in plant growth and development. Past thesis students have shown that treating Catharanthus roseus L. carpels with brassinosteroids has significant effects

A Phytophthora effector hijacks host StKNOX3‐StHUB1/2 complex to reprogram defense gene expression via histone monoubiquitination

The Plant Journal, Volume 127, Issue 5, September 2026.
SUMMARY KNOX (KNOTTED1‐like HOMEOBOX) transcription factors regulate the expression of genes involved in plant growth, development, and immunity by specifically binding to DNA elements. Previously, we found that the Phytophthora infestans RxLR effector Pi22798 targets the potato transcription factor StKNOX3 to promote colonization.

Akt-Dependent Anabolic Activity of Natural and Synthetic Brassinosteroids in Rat Skeletal Muscle Cells

, 2016
Brassinosteroids are plant-derived polyhydroxylated derivatives of 5α-cholestane, structurally similar to cholesterol-derived animal steroid hormones and insect ecdysteroids.

Combining Individual Protective Covers and Homobrassinolide Treatment Prolongs Tree Health and Increases Fruit Yield in Young Tango Mandarin Trees Under Endemic HLB

Agronomy
Huanglongbing (HLB), caused by Candidatus Liberibacter asiaticus (CLas) and vectored by Asian citrus psyllid (Diaphorina citri), remains a major constraint to sustainable citrus production.

Studies on the Effect of Brassinosteroids on the Qualitative Changes in the Storage Roots of Radish [PDF]

, 2012
The effect of 24-epibrassinolide and 28-homobrassinolide on the qualitative changes in the storage roots of radish was studied. Brassinosteroids stimulated the growth of radish roots.
