SummaryEcologists are being challenged to predict how ecosystems will respond to climate changes. According to the Multi‐Colored World (MCW) hypothesis, climate impacts may not manifest because consumers such as fire and herbivory can override the influence of climate on ecosystem state. One MCW interpretation is that climate determinism fails because alternative ecosystem states (AES) are possible

Effector MoSDT1 enhances Magnaporthe oryzae virulence and plays a dual role in regulating rice defense Plant Physiol. (IF 6.5) Pub Date : 2024-07-09 Hongfeng Chen, Shunyu Su, Shumin Yang, Tianqi Zhao, Ping Tang, Qiong Luo, Yuanyuan Zhong, Jing Yang
C2H2 zinc effectors are a class of pathogen proteins that play a dual role in plant-pathogen interactions, promoting pathogenicity and enhancing plant defense. In our previous research, we identified MoSDT1 (Magnaporthe Oryzae Systemic Defense Trigger 1) as a C2H2 zinc effector that activates rice (Oryza sativa) defense when overexpressed in rice. However, its regulatory roles in pathogenicity and

Two Calcium Sensor-Activated Kinases Function in Root Hair Growth Plant Physiol. (IF 6.5) Pub Date : 2024-07-09 Xianming Fang, Beibei Liu, Haiyan Kong, Jingyou Zeng, Yixin Feng, Chengbin Xiao, Qianshuo Shao, Xuemei Huang, Yujun Wu, Aike Bao, Jia Li, Sheng Luan, Kai He
Plant pollen tubes and root hairs typical polarized tip growth. It is well established that calcium ions (Ca2+) play essential roles in maintaining cell polarity and guiding cell growth orientation. Ca2+ signals are encoded by Ca2+ channels and transporters and are decoded by a variety of Ca2+-binding proteins often called Ca2+ sensors, in which calcineurin B-like protein (CBL) proteins function by

Bt corn and cotton planting may benefit peanut growers by reducing aflatoxin risk Plant Biotech. J. (IF 10.1) Pub Date : 2024-07-08 Jina Yu, David A. Hennessy, Felicia Wu
SummaryDecades of studies have shown that Bt corn, by reducing insect damage, has lower levels of mycotoxins (fungal toxins), such as aflatoxin and fumonisin, than conventional corn. We used crop insurance data to infer that this benefit from Bt crops extends to reducing aflatoxin risk in peanuts: a non‐Bt crop. In consequence, we suggest that any benefit–cost assessment of how transgenic Bt crops

The H1/H5 domain contributes to OsTRBF2 phase separation and gene repression during rice development Plant Cell (IF 10.0) Pub Date : 2024-07-08 Hua Xuan, Yanzhuo Li, Yue Liu, Jingze Zhao, Jianhao Chen, Nan Shi, Yulu Zhou, Limin Pi, Shaoqing Li, Guoyong Xu, Hongchun Yang
Transcription factors (TFs) tightly control plant development by regulating gene expression. The phase separation of TFs plays a vital role in gene regulation. Many plant TFs have the potential to form phase-separated protein condensates; however, little is known about which TFs are regulated by phase separation and how it affects their roles in plant development. Here, we report that the rice (Oryza
