Distinct hormonal and morphological control of dormancy and germination in Chenopodium album dimorphic seeds

open access: yesFrontiers in Plant Science, 2023
Dormancy and heteromorphism are innate seed properties that control germination timing through adaptation to the prevailing environment. The degree of variation in dormancy depth within a seed population differs considerably depending on the genotype and

Homozygous Transgenic Barley (Hordeum vulgare L.) Plants by Anther Culture

open access: yesPlants, 2020
Production of homozygous lines derived from transgenic plants is one of the important steps for phenotyping and genotyping transgenic progeny. The selection of homozygous plants is a tedious process that can be significantly shortened by androgenesis ...

Regulation of body growth [PDF]

open access: yesCurrent Opinion in Pediatrics, 2015
Recent basic studies have yielded important new insights into the molecular mechanisms that regulate growth locally. Simultaneously, clinical studies have identified new molecular defects that cause growth failure and overgrowth, and genome-wide association studies have elucidated the genetic basis for normal human height variation.The Hippo pathway ...

Auxin-mediated seed germination and crosstalk with other phytohormones

open access: yesFrontiers in Plant Science
Seed germination is a critical and highly regulated process that transitions a dormant seed to an actively growing seedling. This process plays a vital physiological role in regulating seedling establishment, plant growth, and development, while ...

Innovative UAV LiDAR Generated Point-Cloud Processing Algorithm in Python for Unsupervised Detection and Analysis of Agricultural Field-Plots

open access: yesRemote Sensing, 2021
The estimation of plant growth is a challenging but key issue that may help us to understand crop vs. environment interactions. To perform precise and high-throughput analysis of plant growth in field conditions, remote sensing using LiDAR and unmanned ...

Quantification of karrikins in smoke water using ultra-high performance liquid chromatography–tandem mass spectrometry

open access: yesPlant Methods, 2019
Background Karrikins (KARs) are plant growth regulators that promote seed germination and the subsequent growth and development of seedlings of many plant species.

Hormonal crosstalk controls cell death induced by kinetin in roots of Vicia faba ssp. minor seedlings

open access: yesScientific Reports, 2023
Studies of vitality/mortality of cortex cells, as well as of the concentrations of ethylene (ETH), gibberellins (GAs), indolic compounds/auxins (ICs/AUXs) and cytokinins (CKs), were undertaken to explain the hormonal background of kinetin (Kin)-regulated

Growth Regulation by Macrophages [PDF]

open access: yes, 1982
The evidence reviewed here indicates that macrophages, either acting alone or in concert with other cells, influence the proliferation of multiple types of cells. Most of the data indicate that these effects are mediated by soluble macrophage-elaborated products (probably proteins) although the role of direct cell-to-cell contacts cannot be ruled out ...

Plant hormone cytokinin at the crossroads of stress priming and control of photosynthesis

open access: yesFrontiers in Plant Science, 2023
To cope with biotic and abiotic stress conditions, land plants have evolved several levels of protection, including delicate defense mechanisms to respond to changes in the environment. The benefits of inducible defense responses can be further augmented

ZINC-FINGER interactions mediate transcriptional regulation of hypocotyl growth in Arabidopsis [PDF]

open access: yes, 2018
Integration of environmental signals and interactions among photoreceptors and transcriptional regulators is key in shaping plant development. TANDEM ZINC-FINGER PLUS3 (TZP) is an integrator of light and photoperiodic signaling that promotes flowering in
