Skotomorphogenesis exploits threonine to promote hypocotyl elongation

Quantitative Plant Biology, 2022
Abstract Mobilisation of seed storage reserves is important for seedling establishment in Arabidopsis . In this process, sucrose is synthesised from triacylglycerol via core metabolic processes.

Phytochrome, Gibberellins, and Hypocotyl Growth (A Study Using the Cucumber (Cucumis sativus L.) long hypocotyl Mutant) [PDF]

Plant Physiology, 1995
The possible involvement of gibberellins (GAs) in the regulation of hypocotyl elongation by phytochrome was examined. Under white light the tall long hypocotyl (lh) cucumber (Cucumis sativus L.) mutant, deficient in a type B-like phytochrome, shows an increased "responsiveness" (defined as response capability) to applied GA4 (the main endogenous active

Auxin and Gibberellins Are Required for the Receptor-Like Kinase ERECTA Regulated Hypocotyl Elongation in Shade Avoidance in Arabidopsis

Frontiers in Plant Science, 2018
Plants use shade avoidance strategy to escape the canopy shade when grown under natural conditions. Previous studies showed that the Arabidopsis receptor-like kinase ERECTA (ER) is involved in shade avoidance syndrome.

Exogenously Applied Polyamines Reduce Reactive Oxygen Species, Enhancing Cell Division and the Shoot Regeneration from Brassica oleracea L. var. capitata Protoplasts

Agronomy, 2021
Polyamines (PAs) are organic molecules that are found in plants and animals. In plants, they are involved in the regulation of cellular growth, apoptosis, rooting, flower development, and stress responses.

Influence of altered temperatures on allelopatic properties of Amaranthus cruentus L.

Acta Agriculturae Slovenica, 2017
The relationships between allelochemicals and environmental factors are a key factor for the growth of plants under rotation. We investigated the allelopathic potential of Amaranthus cruentus L, grown under different temperature conditions in in vitro ...

Auxin Asymmetry during Gravitropism by Tomato Hypocotyls [PDF]

Plant Physiology, 1989
Gravitropic asymmetry of auxin was observed in hypocotyls of tomato (Lycopersicon esculentum Mill.) soon after horizontal placement: the ratio of apically supplied [3H]IAA collected from the lower sides to that from the upper sides was about 1.4 between 5 and 10 minutes. This was adequately early to account for the beginning of curvature.

Telomere‐to‐Telomere Genomes Reveal that Multiscale Evolution Shapes the Largest Metabolic Arsenal of Diaporthe Fungi

Advanced Science, EarlyView.
This study presents the first telomere‐to‐telomere genomes and population resources for Diaporthe pathogens, uncovering the largest known fungal repertoire of secondary metabolite gene clusters. Structural variations and horizontal gene transfer drive cluster diversification, while specific rapidly evolving clusters control virulence, offering novel ...

Single‐Cell Transcriptomics Reveals FLS2‐Dependent Hypoxia Signaling and ERF13‐Mediated Transcription During flg22‐Triggered Immunity

Advanced Science, EarlyView.
This study employs sc‐RNA sequencing, genetics, and phenotyping to systematically map the cell‐type‐specific immune responses triggered by flg22. It reveals FLS2‐dependent transcriptional reprogramming in epidermal and mesophyll cells, and uncovers crosstalk between immune and hypoxia signaling pathways.

Organospecific reactions of yellow lupin seedlings to lead

Acta Societatis Botanicorum Poloniae, 2014
Changes caused by lead, supplied in the form of Pb(NO3)2, in roots and hypocotyls of 4 day old yellow lupin (Lupinus luteus L. cv. ventus) seedlings have been analyzed using a transmission electron microscope and polyacrylamide gel electrophoresis (PAGE).
