By Lingya Yao and Xiaochun Ge
Background: Abscisic acid (ABA) is an important plant hormone that regulates plant seed dormancy and stress responses, especially drought responses.…
Understanding ER Stress in Maize
Research, The Plant Cell, The Plant Cell: In a NutshellBackground: Maize is one of the world’s leading crops that is used for food, feed, and fuel. Maize is vulnerable to adverse environmental conditions that lead to production losses. Such conditions can upset delicate cellular processes in maize cells such as protein folding in the endoplasmic reticulum…

New insights in cell death in plants might generate new leads for weed control
Blog, The Plant Cell, The Plant Cell: NewsSource: SeedQuest
Some plants like the giant sequoia trees can grow into the “Largest Living Things on Earth”. Ironically, most of a tree’s biomass is actually not alive, but is formed by persistent cell corpses that are collectively called wood. Wood development is terminated by a tightly controlled…
Heat Trims the Fat: HIL1 Functions in Lipid Homeostasis
Blog, The Plant Cell, The Plant Cell: In BriefGlobal climate change is one of the most pressing issues facing our world today. The impact of increasing temperatures can be felt in diverse areas, including human health and disease, natural ecosystems, and food security. In the agricultural sector, deciphering how plants respond to changing environmental…
Predominant Golgi-residency of the plant K/HDEL receptor is essential for its function in mediating ER retention (Plant Cell)
Plant Science Research WeeklyCells use a sophisticated sorting system to ensure that proteins get to the proper destination. Proteins that are supposed to stay in the ER carry special tags (KDEL or HDEL, recognized by the ERD2 receptor) that prevent them from being swept along with other proteins out of the ER and into the Golgi.…
Chloroplast biogenesis controlled by DELLA-TOC159 interaction in early plant development (Curr. Biol.)
Plant Science Research WeeklyPlant photosynthesis occurs in the chloroplast, the green organelles that are the most famous members of the plastid family. Chloroplast biogenesis starts with illumination at germination, when the colorles, non-photosynthetic proplastid acquires photosynthetic activity as it greens. Gaining photosynthetic…
