Ni et al. explore the relationship between ethylene, the ERF9 and RAP2.4 transcription factors, and anthocyanin biosynthesis in pear. Plant Cell By J. Ni1,3,4, S. Bai1,3,4 and Y. Teng1,2,3,4 1 Department of Horticulture, Zhejiang University, Hangzhou, Zhejiang 310058, PR China 2 Hainan Institute…

Deng, Yang, Li, Chang, Sun et al. explore the interaction between EIN3-like transcription factors and subunits of the Mediator complex in tomato fruit ripening. Background: Fruit ripening relies on the precise spatiotemporal control of RNA polymerase II (Pol II)-dependent transcription of thousands…

The phytohormone ethylene is known for its importance in plant development and mostly for its role in fruit ripening. However, in this review Huang et al. summarize recent findings on ethylene’s role in temperature (hot and cold) stress response and ethylene crosstalk with other hormones. Interestingly,…

Wang et al. explore how plants maintain apical etiolation. By Jiajun Wang (Southwest University, China), Haodong Chen (Tsinghua University, China), Xing Wang Deng (Peking University, China), Ning Wei (Southwest University, China) Background: Seeds germinate underneath the soil; to help the shoot…

Unanticipated flooding conditions challenge the survival and overall growth and development of a plant, for example stomatal development is suppressed under submerged conditions. Stomata are microscopic pores on the surface of leaves of a plant that play an important role in the exchange of gases between…

Huang et al. unravel the roles of ethylene in tomato fruit growth and ripening.  Background: Fruit development is an intriguing evolutionary strategy that functions in both seed protection and seed dispersal. Tomato (Solanum lycopersicum) has long been used as a model system to uncover mechanisms…

Humidity is considered a key component for the growth of fungal plant pathogens. For many infection assays we either maintain plants in high humidity, or wrap the infected area and keep spraying it with water. This is generally performed to facilitate fungal growth and the assumption that this may not…

Qin et al. identify a mechanism by which ethylene activates gibberellin catabolism to determine primary root growth in rice. Hua Qin and Rongfeng Huang Biotechnology Research Institute, Chinese Academy of Agricultural Sciences Background: The optimization of root architecture is one of the…
