Cold influences male reproductive development in plants : a hazard to fertility, but a window for evolution [PDF]

, 2019
Being sessile organisms, plants suffer from various abiotic stresses including low temperature. In particular, male reproductive development of plants is extremely sensitive to cold which may dramatically reduce viable pollen shed and plant fertility ...

Tapetal Expression of BnaC.MAGL8.a Causes Male Sterility in Arabidopsis

Frontiers in Plant Science, 2019
Monoacylglycerol lipase (MAGL) hydrolyzes monoacylglycerol, producing free fatty acid and glycerol. Although this enzyme has been shown to play important roles in mammal, its potential function in plants remains poorly understood. In a survey of the MAGL

Localisation and origin of the bacteriochlorophyll-derived photosensitizer in the retina of the deep-sea dragon fish Malacosteus niger [PDF]

, 2016
Most deep-sea fish have a single visual pigment maximally sensitive at short wavelengths, approximately matching the spectrum of both downwelling sunlight and bioluminescence.

Functional Characterization of microRNA171 Family in Tomato

Plants, 2019
Deeply conserved plant microRNAs (miRNAs) function as pivotal regulators of development. Nevertheless, in the model crop Solanum lycopersicum (tomato) several conserved miRNAs are still poorly annotated and knowledge about their functions is lacking ...

Perspectives on deciphering mechanisms underlying plant heat stress response and thermotolerance [PDF]

, 2013
Global warming is a major threat for agriculture and food safety and in many cases the negative effects are already apparent. The current challenge of basic and applied plant science is to decipher the molecular mechanisms of heat stress response (HSR ...

Specialized ommatidia of the polarization-sensitive dorsal rim area in the eye of monarch butterflies have non-functional reflecting tapeta [PDF]

, 2018
Many insects exploit sky light polarization for navigation or cruising-course control. The detection of polarized sky light is mediated by the ommatidia of a small specialized part of the compound eye: the dorsal rim area (DRA).
