High levels of genetic variation and differentiation in wild tropical gourds provide a novel resource for cucurbit crop improvement

PLANTS, PEOPLE, PLANET, Volume 6, Issue 4, Page 834-846, July 2024.
The genetic variation of crop wild relatives will be key for our survival, as environmental change represents an increasing global threat for agriculture and food security. Cucurbita lundelliana and Cucurbita okeechobeensis subsp. martinezii are wild relatives of cultivated squashes and pumpkins that could be used for crop improvement.

Especies reactivas de oxígeno y la enzima Superóxido Dismutasa como defensa de las plantas al estrés hídrico

Revista de Investigación Agraria y Ambiental, 2014
El cambio climático a escala global y regional ha influido en la frecuencia e intensidad de fenómenos climáticos extremos como las sequías, incrementado las zonas áridas en el planeta, como consecuencia, los eventos de estrés por sequía han aumentado en ...

Microbe‐induced plant resistance against insect pests depends on timing of inoculation but is consistent across climatic conditions

Functional Ecology, Volume 38, Issue 4, Page 848-860, April 2024.
Read the free Plain Language Summary for this article on the Journal blog. Abstract To cope with abiotic and biotic stressors, plants have developed mutualistic associations with beneficial soil microbes, but little is known about how extreme abiotic conditions impact on microbe‐induce resistance to insect herbivores.

Influence of soil fertility on waterlogging tolerance of two Brachiaria grasses

Agronomía Colombiana, 2015
As a consequence of global warming, rainfall is expected to increase in several regions around the world. This, together with poor soil drainage, will result in waterlogged soil conditions.

Homogeneous microenvironmental conditions under nurses promote facilitation

Functional Ecology, Volume 38, Issue 2, Page 350-362, February 2024.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Biotic interactions are highly affected by species traits and micro‐environmental variability. Research on facilitation has primarily focused on how nurse species alleviate abiotic stress for beneficiary species, while the impact of the micro‐environmental variability ...

Divergent selection in a Mediterranean pine on local spatial scales

Journal of Ecology, Volume 112, Issue 2, Page 278-290, February 2024.
This study highlights how divergent selection in heterogeneous microenvironments shapes and maintains the functional genetic variation within populations of long‐lived forest tree species, being the first to focus on adaptive genetic divergence between south‐ and north‐facing slopes within continuous forest stands.

Leveraging whole‐genome sequencing to estimate telomere length in plants

Molecular Ecology Resources, Volume 24, Issue 2, February 2024.
Abstract Changes in telomere length are increasingly used to indicate species' response to environmental stress across diverse taxa. Despite this broad use, few studies have explored telomere length in plants. Thus, evaluation of new approaches for measuring telomeres in plants is needed.

Descubrimiento de ferroquelatasa 1 en Nicotiana tabacum L.: papel en la respuesta al estrés abiótico y el desarrollo de las plantas

Anales de la Academia de Ciencias de Cuba, 2022
Introducción. Cuba está amenazada por el Cambio Climático. En la fisiología de las plantas participan enzimas que actúan como escudo al estrés oxidativo, siempre asociado a la sa- linidad, el déficit o exceso hídrico y las temperaturas extremas; esas ...
