New paper – Predictability of leaf morphological traits for paleoecological reconstruction: the case of leaf cuticle and leaf dry mass per area

Posted on December 15, 2019 by laanisto

Text by Linda-Liisa Veromann-Jürgenson and Tiina Tosens We just published a paper about the plausibility of using cuticle thickness in gymnosperms as a proxy for leaf mass per dry area (LMA). It was as the result of a wonderful collaboration … Continue reading →

New publication – Are stomata in ferns and allies sluggish? Stomatal responses to CO2, humidity and light and their scaling with size and density

Posted on October 4, 2019 by laanisto

Text by Liisa Kübarsepp Recently our lab published a new paper in New Phytologist on the stomatal reactions of ferns and allies. In this paper, we question the overall sluggishness that is assumed of evolutionarily older plants, and study thoroughly … Continue reading →

New publication – Anatomical constraints to nonstomatal diffusion conductance and photosynthesis in lycophytes and bryophytes

Posted on March 4, 2019 by laanisto

Text by Kristiina Mark Bryophytes – polyphyletic group consisting liverworts, hornworts and mosses – and lycophytes (also known as ‘fern allies’) are considered the earliest living relatives to ancient land plants that first migrated from aquatic environment to land. Both, … Continue reading →

New publication – Glandular trichomes as a barrier against atmospheric oxidative stress: Relationships with ozone uptake, leaf damage, and emission of LOX products across a diverse set of species

Posted on March 25, 2018 by laanisto

Text from Research in Estonia page (translated from this Novaator article) Study led by scientists from the Estonian University of Life Sciences indicate that many crops with hairier leaves tolerate ground-level ozone better. The relative content of ground-level ozone in … Continue reading →

New papers published – Glandular trichomes and stomatal conductance play crucial roles in protecting plants against ozone stress

Posted on January 10, 2018 by laanisto

Text by Shuai Li Two papers studying how plants cope with ozone stress were recently published in the journal Plant Cell & Environment. The first paper estimates the possible protective role of non-glandular and glandular trichomes on the leaf surface … Continue reading →

New paper published – Physiological and structural tradeoffs underlying the leaf economics spectrum

Posted on October 9, 2017 by laanisto

Text and graph by Tiina Tosens In the world-wide leaf economics spectrum (Wright et al. 2004, Nature) variability of three key traits: photosynthesis rate, leaf nitrogen content, and leaf dry mass per area of 2500 species (from study sites with … Continue reading →
