Enabling the study of gene function in gymnosperms: Virus‐induced gene silencing in Ephedra tweedieana

open access: yesApplications in Plant Sciences, EarlyView.
Abstract Premise As the sister clade to angiosperms, extant gymnosperms are crucial for reconstructing ancestral gene regulatory networks in seed plants. This highlights the need for model systems representing each of their distinct lineages. However, tools to quickly and effectively investigate gene function in gymnosperms are still limited due to the

Increase in leaf temperature opens stomata and decouples net photosynthesis from stomatal conductance in Pinus taeda and Populus deltoides x nigra

open access: yesJournal of Experimental Botany, 2017
Highlight Stomatal conductance of two species (a broadleaf and a conifer) increased with increasing temperature. This response was independent of carbon metabolism, plant water status, or vapour pressure difference.

Early evolutionary history of the seed

open access: yesBiological Reviews, EarlyView.
ABSTRACT The seed is an essential stage in the life history of gymnospermous and angiospermous plants, facilitating both their survival and dispersal. We reappraise knowledge of the evolutionary history of the gymnospermous seed, from its origin in the late Devonian through to the well‐known end‐Permian extinctions – an interval encompassing the ...

Plant Water Use Efficiency over Geological Time – Evolution of Leaf Stomata Configurations Affecting Plant Gas Exchange

open access: yesPLoS ONE, 2013
Plant gas exchange is a key process shaping global hydrological and carbon cycles and is often characterized by plant water use efficiency (WUE - the ratio of CO2 gain to water vapor loss).

The Application of Carbon Dots in Crops for Sustainable Agriculture

open access: yesChemistryEurope, EarlyView.
Carbon dots serve as versatile nanoagents across the crop life cycle. They promote plant growth and photosynthesis, enhance resilience to biotic and abiotic stresses, aid in postharvest preservation, and enable sensitive detection of contaminants.

Effects of Ground Level Ozone on Vegetation [PDF]

open access: yes, 2010
All the experiments conducted in this project use ozone exposures that either are already currently occurring or are expected to occur over UK uplands this century, if predictions of increasing „background‟ ozone exposure are correct.

Distribution of stomata on the young plants of cereals.

open access: yesJapanese Journal of Crop Science, 1949
This paper has been reported on distribution of stomata in coleoptile and mesocotyl of several cereals as prelitninary. 1. Number of stomata and its mode of distribution both on adaxial and abaxial sides of coleoptile are different in each crop. 2. Ratios of number of stomata of abaxial side to adaxial side are different in each crop but those are ...

Interaction Between Actin and Microtubules During Plant Development

open access: yesCytoskeleton, EarlyView.
ABSTRACT The dynamic interaction between actin filaments (AFs) and microtubules (MTs) plays a crucial role in regulating key developmental and physiological processes in plant cells, particularly in the formation of specialized cell types with distinct shapes and functions, such as pollen tubes, trichomes, and leaf epidermal cells.

Rice mutants, selected under severe drought stress, show reduced stomatal density and improved water use efficiency under restricted water conditions

open access: yesFrontiers in Plant Science
IntroductionRice is among the least water-use-efficient crops, and rice plants utilise most of their water uptake for transpirational cooling via stomata.
