Gene Regulatory Changes Associated With Phenological Transitions in an Ecologically Significant Tree Species

open access: yesPlant-Environment Interactions, Volume 6, Issue 4, August 2025.
Climate change is driving earlier spring leaf‐out across temperate regions, but the genetic mechanisms and environmental interactions underlying this variability are poorly understood. We conducted a controlled growth chamber experiment using excised northern red oak (Quercus rubra) branches, testing the influence of temperature and photoperiod on leaf

Plants and Graviperception [PDF]

open access: yesفناوری در مهندسی هوافضا, 2019
Plants have different mechanisms for understanding and responding to environmental stimuli cues. Gravity is one of the most important directional environmental cues to control growth direction, that plants can permanently adapt to it. Gravitropism can be

Gravitropism in plants: Hydraulics and wall growth properties of responding cells [PDF]

open access: yes
Gravitropism is the asymmetrical alteration of plant growth in response to a change in the gravity vector, with the typical result that stems grow up and roots grow down.

Smartphones, time-lapse and responsible use in the school laboratory [PDF]

open access: yes, 2012
Reports how observing and recording simple biological phenomena over an extended timescale could be enhanced by digital technology, the journey took surprising turns and twists into questions relating to ethics, child protection and reviewing acceptable ...

Exploring the Critical Environmental Optima and Biotechnological Prospects of Fungal Fruiting Bodies

open access: yesMicrobial Biotechnology, Volume 18, Issue 8, August 2025.
Mechanisms and strategies for fungal fruiting body development (FBD) are reported. The critical optima for the relevant environmental cues regulating FBD were synthesised. Fruiting body biotechnological applications and recent advances in designed approaches are elucidated.

Anatomical changes of xylem cells in stem of Pinus radiata seedlings exposed to inclination and ethylene

open access: yesBiologia Plantarum, 2013
In conifers, relationship between ethylene and the response to inclination are not well understood. The aim of this work was to study the consequence for the application of 2-chloroethyl phosphonic acid (ethephon), compound able to release ethylene, in ...

Comparative effects of auxin and abscisic acid on growth, hydrogen ion efflux and gravitropism in primary roots of maize [PDF]

open access: yes
In order to test the idea that auxin action on root growth may be mediated by H(+) movement, the correlation of auxin action on growth and H(+) movement in roots was examined along with changes in H(+) efflux patterns associated with the asymmetric ...

Negative gravitropic response of roots directs auxin flow to control root gravitropism.

open access: yesPlant, Cell and Environment, 2019
Root tip is capable of sensing and adjusting its growth direction in response to gravity, a phenomenon known as root gravitropism. Previously, we have shown that negative gravitropic response of roots (NGR) is essential for the positive gravitropic ...

A method for the quantification of phototropic and gravitropic sensitivities of plants combining an original experimental device with model-assisted phenotyping: Exploratory test of the method on three hardwood tree species.

open access: yesPLoS ONE, 2019
Perception of inclination in the gravity field and perception of light direction are two important environmental signals implicated in the control of plant shape and habit. However, their quantitative study in light-grown plants remains a challenge.
