MicroRNA1432 regulates rice drought stress tolerance by targeting the CALMODULIN-LIKE2 gene Plant Physiol. (IF 7.4) Pub Date : 2024-03-11 Guangyu Luo, Lin Li, Xiaoyu Yang, Yu Yu, Lei Gao, Beixin Mo, Xuemei Chen, Lin Liu
Due to climate change, drought has become a major threat to rice (Oryza sativa L.) growth and yield worldwide. Understanding the genetic basis of drought tolerance in rice is therefore of great importance. Here, we identified a microRNA, miR1432, which regulates rice drought tolerance by targeting the CALMODULIN-LIKE2 (OsCaML2) gene. Mutation of MIR1432 (Bhardwaj et al., 2014). Moreover, recent studies

Woolly mutation with Get02 locus overcomes the polygenic nature of trichome-based pest resistance in tomato Plant Physiol. (IF 7.4) Pub Date : 2024-03-11 Eloisa Vendemiatti, Inty O Hernández-De Lira, Roxane Snijders, Tanmayee Torne -Srivastava, Rodrigo Therezan, Gabriela Simioni Prants, Carlos Lopez-Ortiz, Umesh Reddy, Petra Bleeker, Craig A Schenck, Lázaro Eustáquio Pereira Peres, Vagner Augusto Benedito
Type-IV glandular trichomes, which only occur in the juvenile developmental phase of the cultivated tomato (Solanum lycopersicum), produce acylsugars that broadly protect against arthropod herbivory. Previously, we introgressed the capacity to retain type-IV trichomes in the adult phase from the wild tomato, Solanum galapagense, into the cultivated species cv. Micro-Tom (MT). The resulting MT-Get (MicroTom-Galapagos

Knockout of GRAIN WIDTH2 has a dual effect on enhancing leaf rust resistance and increasing grain weight in wheat Plant Biotech. J. (IF 13.8) Pub Date : 2024-03-09 Shujuan Liu, Hong Liu, Mengjiao Guo, Yuxue Pan, Chenyang Hao, Jian Hou, Liuling Yan, Xueyong Zhang, Xinhong Chen, Tian Li
Wheat leaf rust, caused by the fungal pathogen Puccinia triticina Eriksson (Pt), poses a major threat to global wheat production. The widespread presence and rapid evolution of Pt races lead to frequent epidemics, particularly in favourable climates, causing yield losses of 30%–50% (Prasad et al., 2020). Employing resistant genes and cultivars remains the most effective strategy against leaf rust.

Arbuscular mycorrhizal conserved genes are recruited for ectomycorrhizal symbiosis New Phytol. (IF 9.4) Pub Date : 2024-03-09 Huchen Li, Yueyang Ge, Zhiyong Zhang, Haolin Zhang, Yiyang Wang, Mingdong Wang, Xin Zhao, Jundi Yan, Qian Li, Ling Qin, Qingqin Cao, Ton Bisseling
Introduction Ectomycorrhizal (ECM) symbiosis evolved more recently than the well-studied arbuscular mycorrhizal (AM) symbiosis. AM symbiosis enables plants to take up scarce minerals from the soil through their fungal partner, by its extraradical hyphae and its highly branched intracellular structures named arbuscules. It was predicted to have a single evolutionary origin and to have facilitated the

miR396b/GRF6 module contributes to salt tolerance in rice Plant Biotech. J. (IF 13.8) Pub Date : 2024-03-08 Huanran Yuan, Mingxing Cheng, Ruihua Wang, Zhikai Wang, Fengfeng Fan, Wei Wang, Fengfeng Si, Feng Gao, Shaoqing Li
SummarySalinity, as one of the most challenging environmental factors restraining crop growth and yield, poses a severe threat to global food security. To address the rising food demand, it is urgent to develop crop varieties with enhanced yield and greater salt tolerance by delving into genes associated with salt tolerance and high‐yield traits. MiR396b/GRF6 module has previously been demonstrated

Proteolytic control of the RNA silencing machinery Plant Cell (IF 11.6) Pub Date : 2024-03-08 Pascal Genschik, Marlene Schiaffini, Esther Lechner
Studies in plants were often pioneering in the field of RNA silencing and revealed a broad range of small RNA (sRNA) categories. When associated with ARGONAUTE (AGO) proteins, sRNAs play important functions in development, genome integrity, stress responses, and antiviral immunity. Today, most of the protein factors required for the biogenesis of sRNA classes, their amplification through the production

A tail of two horses? Guard cell abscisic acid and carbon dioxide signalling in the Equisetum ferns New Phytol. (IF 9.4) Pub Date : 2024-03-08 Caspar C. C. Chater
Equisetum, or horsetail, is stubborn. This fern is the bane of gardeners and farmers alike and is one of the world's most pernicious agricultural weeds. No wonder it is perhaps the oldest single extant genus of vascular plants. Its mere 16 or so species are the last stout survivors of a mighty lineage rooted deep in the Devonian–Carboniferous coal swamps and forests. Equisetum's story is, in some ways

Signal‐specific spatiotemporal organization of AtRGS1 in plant pattern‐triggered immunity New Phytol. (IF 9.4) Pub Date : 2024-03-08 Bodan Su, Anqi Wang, Jinxing Lin, Daoxin Xie, Xiaoyi Shan
Introduction The plasma membrane (PM) constitutes a regulatory platform for the transduction of external signals into the interior of cells to regulate various physiological processes. The dynamics of plant membrane proteins on the PM, as well as exocytic and endocytic trafficking between the PM and endosomes, are thought to be important determinants that control signaling activation and passivation

The role of thermodiffusion in transpiration New Phytol. (IF 9.4) Pub Date : 2024-03-08 Danielle S. Griffani, Pierre Rognon, Graham D. Farquhar
Summary Plant leaf temperatures can differ from ambient air temperatures. A temperature gradient in a gas mixture gives rise to a phenomenon known as thermodiffusion, which operates in addition to ordinary diffusion. Whilst transpiration is generally understood to be driven solely by the ordinary diffusion of water vapour along a concentration gradient, we consider the implications of thermodiffusion
