Pinus radiata D. Don is one of the most abundant species in the north of Spain. Knowledge of drought response mechanisms is essential to guarantee plantation survival under reduced water supply as predicted in the future. Tolerance mechanisms are being studied in breeding programs, because information on such mechanisms can be used for genotype selection. In this paper, we analyze the changes o...

Diplodia pinea (syn. Sphaeropsis sapinea) is a well-known latent pathogen of Pinus spp. with a worldwide distribution. As such, this fungus is native where pines are endemic in the northern hemisphere and it has been introduced into all countries of the Southern Hemisphere where pines are exotic. The newly described D. scrobiculata (formerly known as the B morphotype of D. pinea) is thought to ...

the differential expression levels of histone epigenetic marks, being the levels of acetylated Histone H4 and Histone H3K4, associated to gene expression, higher in immature needles whereas the Histone H3K9 was only found in mature needles (Figure 1c). This could be explained by the fact that chromatin needs to be altered and restructured during the differentiation to regulate gene expression [1].

The pitch canker fungus Fusarium circinatum was first associated with mortality of P. radiata in California during the 1980s. Since then it has been dispersed to several countries of the Northern hemisphere together with South Africa and Chile in the southern hemisphere. In Chile the disease caused mortality of seedlings in P. radiata at nursery, and in South Africa the pathogen has already com...

Tree-ring δC is widely employed in ecophysiological studies, because it represents an integra-ted proxy of the ratio between photosynthesis (A) and stomatal conductance (g), which expresses the intrin-sic water use efficiency (iWUE), strongly affected by the environmental conditions experienced by the plant during its life span. Tree-ring δC also reflects long term variations of atmospheric CO2...

Luikov’s theory of heat and mass transfer provides a framework to model drying porous materials. Coupled partial differential equations governing themoisture and heat transfer can be solved using numerical techniques, and in this paper we solve them analytically in a setting suitable for industrial drying situations. We discuss the nature of the solutions using the physical properties of Pinus ...
