Plants and the Logic of Development [PDF]

open access: yesGenetics, 1997
It seems likely that plants and animals have independently evolved multicellular development. Members of each kingdom are composed of different types of eukaryotic cells, implying that the two kingdoms diverged when their common eukaryotic ancestor was unicellular and that each lineage had a considerable unicellular history after they separated.

Remarks on H-infinity Controller Design for SISO Plants with Time Delays [PDF]

open access: yes5th IFAC Symposium on Robust Control Design, 2006, 2020
The skew Toeplitz approach is one of the well developed methods to design H-infinity controllers for infinite dimensional systems. In order to be able to use this method the plant needs to be factorized in some special manner. This paper investigates the largest class of SISO time delay systems for which the special factorizations required by the skew ...

Reactive oxygen species in plant development

open access: yesDevelopment, 2018
Reactive oxygen species (ROS) are produced by metabolic pathways in almost all cells. As signaling components, ROS are best known for their roles in abiotic and biotic stress-related events.

Mechanistic insight into a peptide hormone signaling complex mediating floral organ abscission

open access: yeseLife, 2016
Plants constantly renew during their life cycle and thus require to shed senescent and damaged organs. Floral abscission is controlled by the leucine-rich repeat receptor kinase (LRR-RK) HAESA and the peptide hormone IDA.

Constitutive auxin response in Physcomitrella reveals complex interactions between Aux/IAA and ARF proteins

open access: yeseLife, 2016
The coordinated action of the auxin-sensitive Aux/IAA transcriptional repressors and ARF transcription factors produces complex gene-regulatory networks in plants.

RBOH-Dependent ROS Synthesis and ROS Scavenging by Plant Specialized Metabolites To Modulate Plant Development and Stress Responses.

open access: yesChemical Research in Toxicology, 2019
Reactive oxygen species (ROS) regulate plant growth and development. ROS are kept at low levels in cells to prevent oxidative damage, allowing them to be effective signaling molecules upon increased synthesis.

Convergence of developmental mutants into a single tomato model system: 'Micro-Tom' as an effective toolkit for plant development research

open access: yesPlant Methods, 2011
Background The tomato (Solanum lycopersicum L.) plant is both an economically important food crop and an ideal dicot model to investigate various physiological phenomena not possible in Arabidopsis thaliana. Due to the great diversity of tomato cultivars

Effects of Plant and Soil Characteristics on Phyllosphere and Rhizosphere Fungal Communities During Plant Development in a Copper Tailings Dam

open access: yesFrontiers in Microbiology, 2020
Interactions between plants and microbes can affect ecosystem functions, and many studies have demonstrated that plant properties influence mutualistic microorganisms.

Hydro-Responsive Curling of the Resurrection Plant Selaginella lepidophylla [PDF]

open access: yesScientific Reports 5, 8064 (2015), 2017
The spirally arranged stems of the spikemoss Selaginella lepidophylla, an ancient resurrection plant, compactly curl into a nest-ball shape upon dehydration. Due to its spiral phyllotaxy, older outer stems on the plant interlace and envelope the younger inner stems forming the plant centre.
