• In the presence of abscisic acid or environmental stress, activated SnRK2s transiently phosphorylate Raptor1B, a regulatory component of the TOR complex, to inhibit plant growth. To examine such transient interactions between a kinase and its substrate, comprehensive genetic or biochemistry evidence is more conclusive than a single negative co-immunoprecipitation test.

• Proteins often work as complexes through protein-protein interactions. MicroProteins are small, single-domain proteins that directly bind and fine-tune the activity of target proteins. We summarize the biological roles and action modes of plant microProteins, and outline future directions for applications of microProteins as biotechnological tools in crop bioengineering.

• Specialized endoplasmic reticulum-derived vesicles in plants: Functional diversity, evolution, and biotechnological exploitation

  Author: Xie Li, Xifeng Li, Baofang Fan, Cheng Zhu and Zhixiang Chen

  J Integr Plant Biol 2022, 64 (4): 821-835.

  Published Online: February 15, 2022

   

• Plants produce specialized endoplasmic reticulum (ER)-derived vesicles (ERDVs) that carry specific ER-synthesized proteins but do not travel through the classic ER-to-Golgi secretory pathway. These ERDVs are directly associated with important plant traits. This review discusses our current understanding of the functional diversity, evolution and biotechnological uses of ERDVs in plants.

Breakthrough Report

• Sphingolipid synthesis inhibitor fumonisin B1 causes verticillium wilt in cotton
  Author: Fan Xu, Li Huang, Junyao Wang, Caixia Ma, Yingqing Tan, Fanlong Wang, Yanhua Fan and Ming Luo

  J Integr Plant Biol 2022, 64 (4): 836-842.

   

• The sphingolipid biosynthesis inhibitor fumonisin B1 (FB1) acts as a toxin and phenocopies the symptoms induced by Verticillium dahliae. Overexpressing GhIQD10, which is downregulated in response to FB1 and V. dahliae, enhanced verticillium wilt resistance in cotton by promoting the expression of brassinosteroid and anti-pathogen genes.

  Author: Lihui Yang, Mingyue Zhu, Yi Yang, Ke Wang, Yulei Che, Shurui Yang, Jinxiang Wang, Xin Yu, Lixin Li, Shuang Wu, Klaus Palme and Xugang Li

  J Integr Plant Biol 2022, 64 (4): 843-843.

   

• In Arabidopsis thaliana roots, CELL DIVISION CONTROL PROTEIN 48B functions in regulating the intercellular trafficking of SHORT-ROOT from the stele to the endodermis for formation of the middle cortex.

  Author: Meng Li, Mengxue Wang, Qingyun Lin, Mengyao Wang, Xufang Niu, Jie Cheng, Meizhi Xu, Yaxin Qin, Xinyi Liao, Jian Xu and Shuang Wu

  J Integr Plant Biol 2022, 64 (4): 859-870.

   

• Exploring the regulation of root development by differentiated columella cells through auxin distribution by specifically blocking root cap symplast pathway signaling highlights the vital role of communication between differentiated root cap cells in root development.

• The Mediator subunit OsMED25 functions in DROUGHT AND SALT TOLERANCE (DST)–CYTOKININ OXIDASE/DEHYDROGENASE 2 (OsCKX2) modulated transcriptional regulation, interacting with DST at the OsCKX2 promoter, and thus affecting spikelet number.

  Author: Jian‐Qiang Yu, Kai‐Di Gu, Li‐Li Zhang, Cui‐Hui Sun, Quan‐Yan Zhang, Jia‐Hui Wang, Chu‐Kun Wang, Wen‐Yan Wang, Meng‐Chi Du and Da‐

• In apple leaves and fruits, the basic helix-loop-helix transcription factor MdbHLH3 regulates sugar accumulation by activating expression of the pyrophosphate-dependent phosphofructokinase gene MdPFPβ and coordinating carbohydrate allocation.

• The NuA4 histone acetyltransferase complex components EPL1A and EPL1B function redundantly in histone acetylation and transcriptional activation of chlorophyll biosynthesis and photosynthesis-related genes and thereby contribute to photomorphogenesis.

Photosynthesis and Crop Physiology

  Author: Weining Zhu, Linqing Xu, Xiaoxia Yu and Ying Zhong

   

• Chloroplast cyclophilin28 affects plant leaf growth, flowering time, and photosynthetic efficiency in Arabidopsis thaliana, and this protein likely regulates Photosystem II–Light-harvesting complex II supercomplex assembly and accumulation by altering the configuration of proline 139 of Lhcb6 via its peptidyl-prolyl cis/trans isomerase activity.

Plant-abiotic Interactions

• The MIEL1-ABI5/MYB30 regulatory module fine tunes abscisic acid signaling during seed germination
  Author: Kaili Nie, Hongyun Zhao, Xiaopei Wang, Yanli Niu, Huapeng Zhou and Yuan Zheng

  J Integr Plant Biol 2022, 64 (4): 930-941.

   

• Releasing the restriction imposed by abscisic acid (ABA) allows seed germination. ABA-INSENSITIVE5 (ABI5) is the major ABA activator during germination and the MYB30-INTERACTING E3 LIGASE1–ABI5–MYB30 regulatory module fine tunes ABA signaling during germination via precising regulation of ABI5.

• Nitrate transporter NRT1.1 and anion channel SLAH3 form a functional unit to regulate nitrate-dependent alleviation of ammonium toxicity 
  Author: Chengbin Xiao, Doudou Sun, Beibei Liu, Xianming Fang, Pengcheng Li, Yao Jiang, Mingming He, Jia Li, Sheng Luan and Kai He

  J Integr Plant Biol 2022, 64 (4): 942-957.

   

• When ammonium is the dominant nitrogen source, the uptake of ammonium by plants often dramatically acidifies the rhizosphere, severely inhibiting plant growth. However, a nitrate transporter–channel complex mediates nitrate transmembrane cycling and alleviates ammonium toxicity by preventing rhizosphere acidification.
