Strigolactone-induced senescence of a bamboo leaf in the dark is alleviated by exogenous sugar.

J Pestic Sci 2018 Aug;43(3):173-179

The Nurturing Station for the State Key Laboratory of Subtropical Silviculture, Zhejiang Agriculture and Forestry University, 666, Wusu Rd, Lin'an, China.

Strigolactones (SLs) are a series of sesquiterpene lactones that serve as plant hormones to regulate plant growth and development, such as shoot branching, lateral root formation, and root hair elongation. Recently, SLs have been reported to accelerate the leaf senescence, which is also regulated by sugar signals. In this study, we utilized segments of a bamboo leaf to observe leaf senescence and confirmed that SL accelerates leaf senescence and triggers cell death under a dark condition rather than under a light condition.

Distinctive diet-tissue isotopic discrimination factors derived from the exclusive bamboo-eating giant panda.

Integr Zool 2016 Nov;11(6):447-456

Key Laboratory of Animal Ecology and Conservational Biology, Institute of Zoology, Chinese Academy of Sciences, Beijing, China.

Stable isotope analysis is very useful in animal ecology, especially in diet reconstruction and trophic studies. Differences in isotope ratios between consumers and their diet, termed discrimination factors, are essential for studies of stable isotope ecology and are species-specific and tissue-specific. Given the specialized bamboo diet and clear foraging behavior, here, we calculated discrimination factors for carbon and nitrogen isotopes from diet to tissues (tooth enamel, hair keratin and bone collagen) for the giant panda (Ailuropoda melanoleuca), a species derived from meat-eating ancestors.

Netherton syndrome with ichthyosis linearis circumflexa and trichorrhexis invaginatum.

Dermatol Online J 2014 Dec 16;20(12). Epub 2014 Dec 16.

New York University School of Medicine.

Netherton syndrome is a rare, autosomal recessive disorder that is characterized by congenital ichthyosis, trichorrhexis invaginata, and atopic diathesis. Ichthyosis presents at birth with erythroderma and subsequently evolves into ichthyosis linearis circumflexa; hair shaft abnormalities tend to present later. The disorder is caused by loss-of-function mutations in the SPINK5 (serine protease inhibitor Kazal-type 5) gene that encodes LEKTI (lympho-epithelial Kazal-type related inhibitor), which is a protease inhibitor that counteracts epidermal proteases involved in desquamation.
