Cheng et al. demonstrate that a fully functional ROP fluorescent fusion protein marks future polarity sites 1–2 cell cycles ahead of growth. The Plant Cell (2020) https://doi.org/10.1105/tpc.20.00440. By Xiaohang Cheng and Magdalena Bezanilla Background: Unlike animals, plants can’t simply run away from their surroundings. To adapt, they must change their growth pattern. Polarity at the […]
María Jazmín Abraham-Juárez, Amanda Schrager-Lavelle et. al. explore how variation in a key floral regulator affects floral development, downstream gene expression and protein complex assembly in maize.

Liang et al. demonstrate that auxin modulates sucrose transport to repress petal abscission in rose. The Plant Cell (2020). https://doi.org/10.1105/tpc.19.00695 By Yue Liang, Chuyan Jiang, Yang Liu, Yuerong Gao, Jingyun Lu, Palinuer Aiwail, Zhangjun Fei, Cai-Zhong Jiang, Bo Hong, Chao Ma and Junping Gao. Background: Abscission, a common process in plants, involves the detachment of […]
Li et al. identify a link between the unfolded protein response and the heat shock response. Plant Cell https://doi.org/10.1105/tpc.20.00260 By Zhaoxia Li and Stephen Howell Plant Sciences Institute, Iowa State University, Ames, Iowa USA Background: In the face of climate change, heat stress tolerance is a critical trait in crop plants. Plants have evolved different […]
Zhou et al. demonstrate that phosphatidylserine regulates Rab GTPase-mediated vesicle trafficking and polar growth of pollen tubes. Plant Cell https://doi.org/10.1105/tpc.19.00844 Background: Pollen tube growth is an indispensable event during double fertilization in flowering plants. This peculiar polarized cell growth, in which the elongation occurs only at the tip area and the growth rate is exceedingly […]
In a systematic multi-lab study, Arora et al. apply a variety of proximity-dependent biotin labelling approaches using several different plant systems and bait proteins, to demonstrate its wide applicability for the plant community. Plant Cell https://doi.org/10.1105/tpc.20.00235. Background: Protein-protein interaction studies rely on preserving the interaction between the bait and prey proteins throughout the process of […]
Yalin Liu, Handong Su, Jing Zhang, et al. explore centromere birth and death by inducing rearrangements via pollen irradiation in maize. Plant Cell https://doi.org/10.1105/tpc.20.00389 Background: The centromere is one of the most important components of chromosomes. Every normal chromosome has one functional centromere. The centromere is essential for accurate orientation and distribution during each cell […]
