Plant stem cell niches

open access: yesThe International Journal of Developmental Biology, 2005
Stem cells are required to support the indeterminate growth style of plants. Meristems are a plants stem cell niches that foster stem cell survival and the production of descendants destined for differentiation. In shoot meristems, stem cell fate is decided at the populational level.

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.

A Split-Stem Lesion on Young Hybrid \u3ci\u3ePopulus\u3c/i\u3e Trees Caused by the Tarnished Plant Bug, \u3ci\u3eLygus Lineolaris\u3c/i\u3e (Hemiptera: [Heteroptera]: Miridae) [PDF]

open access: yes, 2017
The tarnished plant bug, known principally as an agricultural pest, injures young hybrid Populus by feeding on the stems and meristems. Tarnished plant bug eggs, fungi associated with some lesions, and simple mechanical stimuli alone from feeding ...

Growth, yield and economics of greenhouse grown coloured capsicum as influenced by trellis system and plant spacing

open access: yesThe Indian Journal of Agricultural Sciences, 2014
The experiment was laid out in split plot design and the treatments comprised V trellis with two stems (T1), V trellis with four stems (T2) and Spanish trellis (T3) as main plot along with three plant spacing levels, viz. S1 (40 cm × 40 cm), S2 (60 cm ×

Exploring the Phytochemical Landscape of the Early-Diverging Flowering Plant Amborella trichopoda Baill. [PDF]

open access: yes, 2019
Although the evolutionary significance of the early-diverging flowering plant Amborella (Amborella trichopoda Baill.) is widely recognized, its metabolic landscape, particularly specialized metabolites, is currently underexplored.

Obstruction of Water Uptake in cut Chrysanthemum Stems after Dry Storage: Role of Wound-induced Increase in Enzyme Activities and Air Emboli [PDF]

open access: yes, 2009
Hydraulic conductance of cut chrysanthemum stems was lowered by the aspiration of air as well as by a wound-induced plant response. By measuring the hydraulic conductance of stem segments in which air could be introduced into and/or removed from the ...

Cavitation resistance of peduncle, petiole and stem is correlated with bordered pit dimensions in Magnolia grandiflora

open access: yesPlant Diversity, 2021
Variation in resistance of xylem to embolism among flowers, leaves, and stems strongly influences the survival and reproduction of plants. However, little is known about the vulnerability to xylem embolism under drought stress and their relationships to ...

Study on the Regulatory Effects of GA3 on Soybean Internode Elongation

open access: yesPlants, 2021
Excessive plant height is an important factor that can lead to lodging, which is closely related to soybean yield. Gibberellins are widely used as plant growth regulators in agricultural production.
