Reduced snow cover at the alpine treeline: resistance and recovery of saplings

open access: yesNew Phytologist, EarlyView.
Summary At high elevations, tree saplings and shrubs are usually protected by mid‐winter snow cover, although climate change is expected to extend the snow‐free (SF) period. Exposure to winter drought, freeze–thaw events and freezing temperatures will therefore increase, inducing damages to the hydraulic system and to living cells, resulting in reduced

UJI EFEKTIVITAS LARVISIDA REBUSAN DAUN SIRIH (PIPER BETLE L.) TERHADAP LARVA AEDES AEGYPTI : STUDI PADA NILAI LC50, LT50, SERTA KECEPATAN KEMATIAN LARVA

open access: yesJurnal Kedokteran Diponegoro, 2017
Latar Belakang Pengendalian hayati terhadap larva Aedes aegypti semakin banyak digunakan, salah satunya dengan daun sirih. Ekstrak daun sirih efektif dalam membunuh larva Aedes aegypti tetapi pembuatannya cukup rumit untuk dilakukan secara mandiri oleh masyarakat. Penggunaan rebusan daun sirih sebagai larvisida belum pernah diteliti. Tujuan Membuktikan

A Hierarchical VvbHLH30‐VvERF70‐VvACS2 Module Orchestrates Ethylene Biosynthesis and Cold Adaptation in Grapevine

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Ethylene is a key gaseous phytohormone that plays crucial roles in regulating plant growth, development and stress responses. However, ethylene‐associated biosynthetic and transcriptional regulatory mechanisms governing cold‐adaptation responses in plants remain poorly understood.
