Phenotypic plasticity versus ecotypic differentiation under recurrent summer drought in two drought-tolerant pine species

Despite worldwide reports of high tree mortality, growing evidence indicates that many tree species are well adapted to survive repeated dry spells. The drought resilience of trees is related to their phenotypic plasticity and ecotypic differentiation. Whe ...

Workflow to Establish Time-Specific Zones in Precision Agriculture by Spatiotemporal Integration of Plant and Soil Sensing Data

Gabriele Manoli

Management zones (MZs) are used in precision agriculture to diversify agronomic management across a field. According to current common practices, MZs are often spatially static: they are developed once and used thereafter. However, the soil–plant relations ...

Progesterone and Wnt4 control mammary stem cells via myoepithelial crosstalk

Cathrin Brisken, Jacques Rougemont, Ayyakkannu Ayyanan, Marian Caikovski, Renuga Devi Rajaram, Duje Buric

Ovarian hormones increase breast cancer risk by poorly understood mechanisms. We assess the role of progesterone on global stem cell function by serially transplanting mouse mammary epithelia. Progesterone receptor (PR) deletion severely reduces the regene ...

Study of the twinned dendrite tip shape II: Experimental assessment

Michel Rappaz, Marco Cantoni, Pierre Burdet, Mario Alberto Salgado Ordorica

The favorable growth kinetics of twinned dendrites can be explained by their complex morphology, multiple side branching mechanisms, growth undercooling and tip morphology. Three models were proposed for the twinned dendrite tip shape: (i) a grooved tip sa ...

Increased tolerance of sunflower mutant seedlings to Cd and Zn in hydroponic culture

Jean-Paul Schwitzguebel, Erika Nehnevajova

Cadmium and zinc show similarities in their chemistry, geochemistry and environmental properties. Whereas Cd is a phytotoxic non-essential element, Zn is an essential trace element for plant growth and development. Zinc plays a fundamental role in several ...
