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.

Repression of the auxin response pathway increases Arabidopsis susceptibility to necrotrophic fungi

, 2008
In plants, resistance to necrotrophic pathogens depends on the interplay between different hormone systems, such as those regulated by salicylic acid (SA), jasmonic acid (JA), ethylene, and abscisic acid.

A Water‐Saving Drought Survival Phenotype in a Wheat TILLING Mutant Involves Survival‐Biased Metabolic and Phosphorylation Reprogramming

Plant, Cell &Environment, EarlyView.
ABSTRACT Drought tolerance in crops often involves trade‐offs between water conservation, growth and reproduction. Understanding how water‐saving strategies are implemented at physiological and metabolic levels remains critical for improving crop performance under water‐limited conditions.

Exogenous IAA application alleviated altered physiological and biochemical processes through promoting H‐ATPase and Fe chelate reductase activities in common bean (Phaseolus vulgaris L.) subjected to iron deficiency

Plant Biology, EarlyView.
Exogenous IAA supply enhances the strategy I response in common bean under iron deficiency. Abstract Iron deficiency is a common nutritional disorder observed in calcareous soils, where its resolution by classical methods has shown its failure. However, the exploitation of certain potentialities possessed by crops (rhizosphere acidification, H‐ATPase ...

Time‐ and space‐resolved transcriptional regulation in Arabidopsis thaliana

Plant Biology, EarlyView.
Transcript abundance patterns in time and space of kinases, E3 ligases and transcription factors in Arabidopsis thaliana demonstrate ample room for dynamic and specific regulation of metabolism and stress responses. Abstract General metabolism and responses to internal or external signals are tightly regulated in plants.

Locally adapted Arabidopsis thaliana accessions show transcriptomic plasticity in a multi‐timescale analysis of whole‐genome gene expression in a natural environment

Plant Biology, EarlyView.
Natural Arabidopsis thaliana accessions showed remarkable plasticity in both life‐cycle phenology and whole‐genome gene expression patterns in in natura field experiments. Nevertheless, local adaptation in fitness‐related life‐history traits can also be detected at the whole‐genome gene expression level.

トウモロコシ ミジュク シュシ ニ フクマレル ショクブツ セイチョウ ブッシツ ノ タンリ ト ドウテイ [PDF]

, 1998
【抄録】植物の未熟種子は完成された種子の形成に向けて活性状態にあると考えられる.したがって,そこに存在し機能している生長調節物質は質的にも量的にも完熟種子とは異なることが期待される.本研究はトウモロコシの未熟種子を対象に生長調節物質の検索をおこなった結果を取りまとめたものである.未熟トウモロコシ種子(Zea Mays L.,cv.Honey bantam)の酢酸エチル可溶区中のアセトニトリル可溶区からライスラミナ屈曲試験に強い活性を示す画分を得た.この画分をメタンボロン酸で処理しGC-EI ...

Chemical treatment rescues reduced growth of the autoimmune mutant chs3‐2D without compromising its immune responses

Plant Biology, EarlyView.
We generated a compound by chemical modification that can efficiently rescue growth without decreasing the immune response of the chs3‐2D autoimmune mutants, thus chemically uncoupling its growth–defence trade‐off. Abstract Plant development in many species including Arabidopsis relies on the accurate balance between growth and defence.

Effects of dopamine on reducing salt stress damage in pepper (Capsicum annuum L.) at morphological, physiological, biochemical, and molecular levels

Annals of Applied Biology, Volume 189, Issue 1, July 2026.
Salt stress causes oxidative and osmotic stress, resulting in decreased nutrient uptake, plant growth, and photosynthetic rate. This study suggests that foliar application of dopamine can reduce salinity‐induced oxidative damage in pepper plants by altering antioxidant activity, biochemical, and molecular responses.
