Structural Analysis of Reproductive Development in Pistillate Flowers of Laurus nobilis L.

open access: yesNotulae Botanicae Horti Agrobotanici Cluj-Napoca, 2013
In Laurus nobilis L. (Lauraceae) the development of female flowers (pistillate), between floral meristem differentiation and fruit formation was inspected through histological sections and SEM techniques. The reproductive development of the female flower

Localization of acid phosphatase in the differentiating root meristem

open access: yesBiologia Plantarum, 1964
The localization of acid phosphatase was studied by Gomori’s newer technique and by azo-coupling methods (α-naphthyl phosphate + fast red ITR or fast garnet GBC; AS or AS D phosphate + fast blue B or fast red violet LB) in the root tips ofVicia faba L. on paraffin sections (fixation with Wolman’s acidified ethanol) and on frozen sections (fixation with

DNA methylation is reconfigured at the onset of reproduction in rice shoot apical meristem

open access: yesNature Communications, 2020
The shoot apical meristem of flowering plants transitions from forming leaves to floral organs. Here Higo et al. show that DNA methylation of many transposons that are hypermethylated in gametes is established in the SAM before flowering, suggesting it ...

Interplay between Proline Metabolism and ROS in the Fine Tuning of Root-Meristem Size in Arabidopsis

open access: yesPlants, 2022
We previously reported that proline modulates root meristem size in Arabidopsis by controlling the ratio between cell division and cell differentiation.

From A. rhizogenes RolD to Plant P5CS: Exploiting Proline to Control Plant Development [PDF]

open access: yes, 2018
The capability of the soil bacterium Agrobacterium rhizogenes to reprogram plant development and induce adventitious hairy roots relies on the expression of a few root-inducing genes (rol A, B, C and D), which can be transferred from large virulence ...

Cadmium and arsenic affect root development in Oryza sativa L. negatively interacting with auxin [PDF]

open access: yes, 2018
Cadmium (Cd) and arsenic (As), non essential, but toxic, elements for animals and plants are frequently present in paddy fields. Oryza sativa L., a staple food for at least the half of world population, easily absorbs As and Cd by the root, and in this ...

Callose homeostasis at plasmodesmata: molecular regulators and developmental relevance [PDF]

open access: yes, 2014
Plasmodesmata are membrane-lined channels that are located in the plant cell wall and that physically interconnect the cytoplasm and the endoplasmic reticulum (ER) of adjacent cells.

Plant Cellular and Molecular Biotechnology: Following Mariotti's Steps [PDF]

open access: yes, 2019
This review is dedicated to the memory of Prof. Domenico Mariotti, who significantly contributed to establishing the Italian research community in Agricultural Genetics and carried out the first experiments of Agrobacterium-mediated plant genetic ...

Cadmium and arsenic-induced-stress differentially modulates Arabidopsis root architecture, peroxisome distribution, enzymatic activities and their nitric oxide content [PDF]

open access: yes, 2020
In plant cells, cadmium (Cd) and arsenic (As) exert toxicity mainly by inducing oxidative stress through an imbalance between the production of reactive oxygen species (ROS) and reactive nitrogen species (RNS), and their detoxification. Nitric oxide (NO)

Differential spatial distribution of miR165/6 determines variability in plant root anatomy [PDF]

open access: yes, 2017
A clear example of interspecific variation is the number of root cortical layers in plants. The genetic mechanisms underlying this variability are poorly understood, partly due to the lack of a convenient model.
