Changes in Foliar Water Uptake Caused by Water Stress in Cattleya Lindl. (Orchidaceae). [PDF]
Physiol PlantABSTRACT In response to water restrictions imposed by the epiphytic environment, orchids have developed strategies to increase water‐use efficiency, such as the expression of Crassulacean Acid Metabolism (CAM) and the foliar water uptake (FWU). In a climate change scenario, FWU may emerge as a strategy to reduce water stress during drought.

From flower to fruit: The origin of the trilocular ovary and fruit development in Phragmipedium longifolium (Warsz. & Rchb.f.) Rolfe (Orchidaceae: Cypripedioideae). [PDF]
Plant Biol (Stuttg)Phragmipedium longifolium has a trilocular ovary with a post‐genital septum, and during fruit development, lignification plays a crucial role in facilitating dehiscence and seed dispersal. Abstract While carpels in Orchidaceae are predominantly unilocular, trilocular carpels can also occur, mainly in branches separated during the early diversification ...

Auxin-Dependent Activation of RHD6-RSL4 Cascade Promotes Root Hair Growth Under Boron Deficiency in Arabidopsis Primary Root Apices. [PDF]
Plant Cell EnvironABSTRACT Plants rapidly adjust their root system architecture to enhance resource uptake and cope with fluctuating soil environments. One such adaptive response is the development of root hairs (RH), which increase the effective root surface area and thereby improve water and nutrient acquisition.
