Control biológico de enfermedades mediante el tratamiento de semillas de cucurbitáceas con rizobacterias promotoras del crecimiento de las plantas (PGPR).

open access: yesAgrisost, 2014
Las regulaciones sobre la producción de alimentos sanos limitan actualmente el uso de fungicidas sintéticos para el tratamiento de semillas y, por otra parte, no se dispone de bactericidas efectivos. Se condujeron experimentos en condiciones controladas

Molecular breeding approaches for the improvement of oil content and fatty acid composition in exotic‐derived maize germplasm

open access: yesNew Phytologist, Volume 248, Issue 4, Page 1920-1939, November 2025.
Summary Molecular breeding strategies such as genome‐wide association studies (GWAS) and genomic prediction have revolutionized crop improvement by enhancing selection accuracy and genetic gains. Through a comprehensive evaluation of a large set of maize lines from Germplasm Enhancement of Maize (BGEM) and their testcross hybrids, we aimed to ...

Unlocking grass leaf development: foundations for tunable cereal design

open access: yesNew Phytologist, Volume 248, Issue 4, Page 1655-1676, November 2025.
Summary The grass leaf plays a critical role in global food security, generating the carbon stores in cereal grains, which provide > 50% of global calories. As the global population grows, there is an urgent need to increase food production using fewer resources and to develop more resilient agricultural systems to withstand variable climate conditions

Basal axillary buds in pea are hydraulically connected to the stem but are protected during drought by osmotic adjustment

open access: yesNew Phytologist, Volume 248, Issue 4, Page 1700-1712, November 2025.
Summary Plants prioritise water allocation to tissues that support their survival and reproduction during drought, but little is known about their tissue‐specific drought tolerance mechanisms. In the case of basal buds, the extent to which they are hydraulically connected to the stem is unclear, as are their drought resistance mechanisms.

Breeding for delayed bolting decelerated the circadian clock in cultivated lettuce

open access: yesNew Phytologist, Volume 248, Issue 4, Page 1892-1902, November 2025.
Summary Circadian clocks pace biological events and influence developmental traits, but their role in leafy crop domestication has remained unexplored. We investigated whether selection for delayed bolting during lettuce domestication targeted clock components.
