Large old trees need more conservation attention: A case of Tamarix aphylla in the arid deserts of the United Arab Emirates

open access: yesJournal of Asia-Pacific Biodiversity, 2015
Large old trees are often recognized for the provision of variety of ecosystem services to humanity. This paper reports the existence of a large old Tamarix aphylla (L.) Karst. tree in the Hamriyah area of Sharjah, the United Arab Emirates.

Similarity between seed bank and herb layer in a natural deciduous temperate lowland forest

open access: yesActa Societatis Botanicorum Poloniae, 2011
Forest seed banks mostly studied in managed forests proved to be small, species poor and not reflecting aboveground species composition. Yet studies conducted in undisturbed communities indicate a different seed bank characteristic. Therefore we aimed at

Banana seed genetic resources for food security: Status, constraints, and future priorities

open access: yesFood and Energy Security, 2022
Storing seed collections of crop wild relatives, wild plant taxa genetically related to crops, is an essential component in global food security. Seed banking protects genetic resources from degradation and extinction and provides material for use by ...

Seed rain and seed bank of a draw-down zone and their similarities to vegetation under the regulated water-level fluctuation in Xiangxi River

open access: yesJournal of Freshwater Ecology, 2020
Construction of the Three Gorges Reservoir converted areas of the original terrestrial ecosystem along the shores into a draw-down zone with a fluctuating water-level at an elevation ranging between 145 and 175 m. The water-level fluctuation is regulated

Study the species richness and similarity of plant cover and soil seed bank in arid areas of Atriplex plantation (Case Study: Shahriar) [PDF]

open access: yesپژوهش‌های آبخیزداری, 2017
Plant cover may be the most important factor in conserving the soil from water and wind erosion. Wise management of plant cover needs accurate and sufficient information from vegetation and soil seed bank capacity. Evaluation of changes in vegetation and

In Site Soil Seed-Banks: Size, Composition and Persistence across Tropical Successional Stages

open access: yesPlants, 2023
I investigated the size, composition and persistence of the seed-bank in primary forests, secondary forests and old-fields in southern Mexico. I also assessed the contribution of the seed-bank to regeneration relative to other propagule sources.

Evolutionarily Distinct Enzymes Uncovered Through Sequence Similarity Network Analysis of De Novo Transcriptomes from Underexplored Protist Axenic Cultures

open access: yesFermentation
Protists represent a vast yet underexplored reservoir of enzymatic diversity across the eukaryotic tree of life. In this study, we established axenic strains of diverse protists from four major eukaryotic supergroups using single-cell isolation and ...

The feasibility of using soil seed bank for natural regeneration of degraded sandy grasslands

open access: yesInternational Soil and Water Conservation Research, 2022
Desertification in degraded grasslands is manifested through the development of bare sandy patches, which eventually lead to habitat fragmentation. The ability of these bare sandy patches to regenerate naturally through in-situ soil seed banks is not ...

Soil seed banks [PDF]

open access: yesScientia Agricola, 1998
The goal of this literature review is to discuss some of the major aspects of the soil seed bank, from its characteristics down to methodological aspects of its determination. Soil seed bank is the reservoir of viable seeds or of vegetative propagules that are present in the soil and that are able to recompose a natural vegetation.

Interaction of HS1BP3 with cortactin modulates TKS5 localisation, cell secretion and cancer malignancy

open access: yesMolecular Oncology, EarlyView.
Here, we demonstrate that HS1BP3 interacts with Cortactin through a proline‐rich region (PRR3.1) and show that this interaction, and HS1BP3 itself, promote cancer cell proliferation and invasion. Inhibition of this interaction leads to build‐up of TKS5 in multivesicular endosomes and altered secretion of CD63 and CD9, providing an explanation for the ...
