“…Moreover, the chosen cultivar "Rivendel" is characterized as small-leaved (BSA, 2016). In a study by Vaseva, Akiscan, Demirevska, Anders, and Feller (2011), smallleaved cultivars of T. repens ranged above medium-leaved cultivars in drought stress tolerance due to the expression of genes encoding for dehydrins. For L. corniculatus, Lanta et al (2012) found BM losses under drought stress in a range comparable to that in the present study.…”

Dairy livestock production systems rely on high‐quality forage legumes, which are widely present in grassland swards all over Europe. A future climatic scenario with higher average annual temperatures and lower precipitation is expected to affect grassland productivity in general and the productivity of the most important forage legume species Trifolium repens in particular. One way to cope with such constraints is the adoption of currently underutilized minor legume species with a higher tolerance towards drought stress. Therefore, the present study investigated legume species with lower moisture requirements than T. repens, these are Lotus corniculatus, Medicago falcata, Medicago lupulina and Onobrychis viciifolia in comparison with T. repens. Legumes were grown in containers as monocultures in a roofed open‐sided greenhouse under conditions of optimal water supply or periodic drought stress. Generally, drought stress decreased the biomass production, but species differed in their reaction. Particularly, M. lupulina and L. corniculatus had lower relative biomass losses (−26%) compared to T. repens (−43%, as averaged over drought stress periods). However, in overall biomass production T. repens still was at one level with M. lupulina and L. corniculatus under drought stress. This was related to high stomata control as indicated by the intrinsic water‐use efficiency. We conclude that there are promising future options of forage legumes as alternatives to T. repens.

“…In Siberian spruce, protein levels of the 53 kDa DHN reach the highest levels during winter and decrease rapidly after freezing stress (Kjellsen et al, 2013). In addition, Vaseva et al (2011) compared the gene and protein profile in two drought-resistant pastures Trifolium pratense and T.…”

Dehydrins (DHNs) are intrinsically disordered proteins expressed under cellular dehydration-related stresses. In this study, we identified potential proteolytic PEST sequences located at the central and C-terminal regions from the Opuntia streptacantha OpsDHN1 protein. In order to evaluate these PEST sequences as proteolytic tags, we generated a translational fusion with the GUS reporter protein and OpsDHN1 coding sequence. We found a GUS degradation effect in tobacco agro-infiltrated leaves and Arabidopsis transgenic lines that expressed the fusion GUS::OpsDHN1 full-length. Also, two additional translational fusions between OpsDHN1 protein fragments that include the central (GUS::PEST-1) or the C-terminal (GUS::PEST-2) PEST sequences were able to decrease the GUS activity, with PEST-2 showing the greatest reduction in GUS activity. GUS signal was abated when the OpsDHN1 fragment that includes both PEST sequences (GUS::PEST-1-2) were fused to GUS. Treatment with the MG132 proteasome inhibitor attenuated the PEST-mediated GUS degradation. Point mutations of phosphorylatable residues in PEST sequences reestablished GUS signal, hence these sequences are important during protein degradation. Finally, in silico analysis identified potential PEST sequences in other plant DHNs. This is the first study reporting presence of PEST motifs in dehydrins.

“…Además, los tréboles blancos, debido a la morfología, presentan un menor requerimiento que los tréboles rojos (Vaseva et al, 2011). Sin embargo, en el presente trabajo se presentó la interacción entre el día de evaluación y la variedad en algunas variables de establecimiento (Cuadro 2 y 3).…”

ResumenLos sistemas de lechería en Colombia se basan en el uso de praderas, por lo cual es necesario determinar la respuesta de los forrajes bajo diferentes condiciones ambientales. El objetivo del presente trabajo fue evaluar el establecimiento y la producción de raigrás perennes y tréboles en dos regiones del trópico alto colombiano. Se evaluaron cinco raigrás perennes (tres diploides y dos tetraploides) y tres tréboles (dos rojos y uno blanco) en Tuta, Boyacá y Mosquera, Cundinamarca. Se establecieron parcelas de 8 m 2 de cada especie con tres repeticiones. Las variables de establecimiento fueron evaluadas quincenalmente durante los primeros cinco meses. Las variables de producción y calidad nutricional fueron evaluadas en temporada de lluvia (abril y mayo) y de sequía (junio y julio). Se utilizó un diseño de bloques completos al azar con medidas repetidas, entre noviembre de 2015 y julio de 2016. Durante el periodo de establecimiento, se encontró una mayor cobertura y grado de adaptación en los raigrás y tréboles entre los días 45 y 60 y 105 y 150 en Tuta y Mosquera, respectivamente. La mayor edad provocó una disminución en la energía neta de lactancia (entre 7 y 15%) y un aumento en la producción diaria de materia seca por hectárea (entre 20 y 78 kg). El día de evaluación presentó una mayor influencia respecto a la variedad y la época de lluvias sobre las variables de establecimiento y producción evaluadas en raigrás y tréboles en trópico alto colombiano.Palabras clave: ganado de leche, sistema agropastoril, plantas forrajeras. AbstractColombian dairy systems are based on grasslands; therefore, it is necessary to define forages response under different environmental conditions. The objective of this study was to assess the establishment and production of five perennial ryegrass and three clovers into two regions of Colombian highlands (Tuta, Boyacá and Mosquera, Cundinamarca). Three 8 m 2 plots of each species were established. Establishment variables were evaluated twice a
