Inoculation of in vitro cultures with rhizosphere microorganisms improve plant development and acclimatization during immature embryo rescue in nectarine and pear breeding programs
(Elsevier, 2020-08-14)
In the present study, two fungi Cladosporium ramotenellum strain PGP02 and Phoma spp. strain PGP03 and the bacterium Pseudomonas oryzihabitans PGP01 were isolated from Pyrus and Prunus in vitro rescued ...
Non-volatile signals and redox mechanisms are required for the responses of Arabidopsis roots to Pseudomonas oryzihabitans
(Oxford University Press, 2022-08-24)
Soil bacteria promote plant growth and protect against environmental stresses, but the mechanisms involved remain poorly characterized, particularly when there is no direct contact between the roots and ...
Rhizosphere microorganisms enhance in vitro root and plantlet development of Pyrus and Prunus rootstocks
(Springer, 2021-03-14)
The rooting of fruit tree rootstocks is the most challenging step of the in vitro propagation process.
The use of rhizosphere microorganisms to promote in vitro rooting and plant growth as an alternative ...
Susceptibility Evaluation to Fire Blight and Genome-Wide Associations within a Collection of Asturian Apple Accessions
(MDPI, 2023-12-04)
Fire blight, caused by Erwinia amylovora, is one of the most devastating apple diseases. The selection of cultivars of low susceptibility and the study of the genetic mechanisms of the disease play ...
Adventitious regeneration from haploid melon (Cucumis melo L.) leaves as an approach to increase the frequency of diploid plants
(Springer, 2023-02-16)
An efficient process of adventitious regeneration from haploid plant leaves to increase the proportion of diploid plants of six elite melon lines ‘Védrantais’ French cultivar, ‘Piel de Sapo’ Spanish ...
Using plant growth‑promoting microorganisms (PGPMs) to improve plant development under in vitro culture conditions
(Springer, 2022-05-05)
Plant in vitro culture techniques are highly useful to obtain signifcant amounts of true-to-type and disease-free
plant materials. One of these techniques is clonal micropropagation which consists on ...
Optimization of a food industry-waste-based medium for the production of the plant growth promoting microorganism Pseudomonas oryzihabitans PGP01 based on agro-food industries by-products
(Elsevier, 2021-09-16)
In this study, three wastes based on potato peels and pulps, tomato seeds and wheat bran were used as basis for the preparation of a cheap medium to produce the bacterium P. oryzihabitans PGP01. In ...
Rhizosphere Acidification as the Main Trait Characterizing the Differential In Vitro Tolerance to Iron Chlorosis in Interspecific Pyrus Hybrids
(MDPI, 2022-06-18)
Physiological responses of different interspecific Pyrus hybrids and an open pollinated Pyrus
communis ‘Williams’ (Pcw) grown under in vitro culture conditions simulating lime induced chlorosis
were ...
Differential response to calcium-labelled (44Ca) uptake and allocation in two peach rootstocks in relation to transpiration under in vitro conditions
(Elsevier, 2023-11-28)
Calcium-labelled (44Ca) uptake and transport under in vitro GreenTray® temporary immersion bioreactor conditions have been studied related to aeration conditions. For this aim, Rootpac®-20 (RP-20) and ...
Acidification of the culture medium as a strategy to control endophytic contaminations in Prunus spp. rootstocks cultured in GreenTray TIS bioreactor
(Elsevier, 2021-08-20)
Overgrowth of endophytes in some in vitro cultures may disrupt the normal shoot tip growth and proliferation, being necessary to obtain endophytes-free cultures to achieve a normal plant micropropagation ...
