The plant stem-cell niche and pluripotency: 15 years of an epigenetic perspective [PDF]

open access: yesFrontiers in Plant Science, 2022
Pluripotent stem-cells are slowly dividing cells giving rise to daughter cells that can either differentiate to new tissues and organs, or remain stem-cells.

Plant Stem Cells in Cosmetic Industry [PDF]

open access: yesPlants
It is interesting to note that some of the most lucrative commercial products available today are derived from plant cell cultures. Apple, grape, ginger, rice, and other plant stem cells have been successfully and extensively utilized in cosmetic preparations all over the world. The advantages of plant cell suspensions over field-grown complete plants,

Optical Caliper for Contactless Measurement of Plant Stem Diameter [PDF]

open access: yesSensors
Precision greenhouse agriculture enhances plant health and crop yields by continuously monitoring key plant parameters. Stem diameter is such a parameter and is monitored to support decisions on plant care.

Mechanisms of Alignment in Feeding Aphids on the Plant Stem [PDF]

open access: yesEcology and Evolution
ABSTRACTAphids are observed on various plant species, with most aphids feeding downward on stems. In this study, I studied the variations in feeding postures of aphids and their mechanisms. My field observations revealed that the majority of individuals from most species fed facing downward, or more precisely, towards the roots.

Competition models for plant stems

open access: yesJournal of Differential Equations, 2020
The models introduced in this paper describe a uniform distribution of plant stems competing for sunlight. The shape of each stem, and the density of leaves, are designed in order to maximize the captured sunlight, subject to a cost for transporting water and nutrients from the root to all the leaves.

Potato crop growth as affected by nitrogen and plant density [PDF]

open access: yesPesquisa Agropecuária Brasileira, 2000
Growth and development variables and dry matter characteristics were studied for cultivar Snowden of potato (Solanum tuberosum L.) to evaluate nitrogen and plant density influence. Disregarding ending of season plant stress, the average number of actives

Stem Cells and Regeneration in Plants [PDF]

open access: yesNephron Experimental Nephrology, 2014
<b><i>Background:</i></b> Plants are characterized by indeterminate post-embryonic development that is evident, for example, in the continuous branching of shoots and roots. High competence to regenerate tissues is another consequence of such intrinsic developmental plasticity in plants.

Plant morphology and allometric relationships in competing and non-competing plants of Tagetes patula L.

open access: yesActa Societatis Botanicorum Poloniae, 2014
Allometric relationships (defined as correlation coefficients between plant mass - stem diameter, plant mass - stem height and stem diameter - stem height) in plants of Tagetes patula L. (Brassicaceae) var. "Tangerine" were analyzed.

The Importance of Stem Photosynthesis for Two Desert Shrubs Across Different Groundwater Depths

open access: yesFrontiers in Plant Science, 2022
Water availability could alter multiple ecophysiological processes such as water use strategy, photosynthesis, and respiration, thereby modifying plant water use and carbon gain.
