Arabidopsis hypocotyl growth in darkness requires the phosphorylation of a microtubule-associated protein Plant J. (IF 7.2) Pub Date : 2024-03-17 Denise Soledad Arico, Natalia B. Burachik, Diego Leonardo Wengier, María Agustina Mazzella
Rapid hypocotyl elongation allows buried seedlings to emerge, where light triggers de-etiolation and inhibits hypocotyl growth mainly by photoreceptors. Phosphorylation/dephosphorylation events regulate many aspects of plant development. Only recently we have begun to uncover the earliest phospho-signaling responders to light. Here, we reported a large-scale phosphoproteomic analysis and identified

KU70 and CAF-1 in Arabidopsis: Divergent roles in rDNA stability and telomere homeostasis Plant J. (IF 7.2) Pub Date : 2024-03-17 Michal Závodník, Veronika Pavlištová, Adéla Machelová, Martin Lyčka, Iva Mozgová, Karolína Caklová, Martina Dvořáčková, Jiří Fajkus
Deficiency in chromatin assembly factor-1 (CAF-1) in plants through dysfunction of its components, FASCIATA1 and 2 (FAS1, FAS2), leads to the specific and progressive loss of rDNA and telomere repeats in plants. This loss is attributed to defective repair mechanisms for the increased DNA breaks encountered during replication, a consequence of impaired replication-dependent chromatin assembly. In this

Gibberellins regulate masculinization through the SpGAI-SpSTM module in dioecious spinach Plant J. (IF 7.2) Pub Date : 2024-03-16 Yu-Lan Zhang, Li-Ying Wang, Yi Yang, Xu Zhao, Hong-Wei Zhu, Chen You, Ning Chen, Shuai-Jie Wei, Shu-Fen Li, Wu-Jun Gao
The sex of dioecious plants is mainly determined by genetic factors, but it can also be converted by environmental cues such as exogenous phytohormones. Gibberellic acids (GAs) are well-known inducers of flowering and sexual development, yet the pathway of gibberellin-induced sex conversion in dioecious spinach (Spinacia oleracea L.) remains elusive. Based on sex detection before and after GA3 application

SUMMARYGlutathione (GSH) is required for various physiological processes in plants, including redox regulation and detoxification of harmful compounds. GSH also functions as a repository for assimilated sulfur and is actively catabolized in plants. In Arabidopsis, GSH is mainly degraded initially by cytosolic enzymes, γ‐glutamyl cyclotransferase, and γ‐glutamyl peptidase, which release cysteinylglycine

It's not witchcraft: The role of abscisic acid in Striga germination and conditioning Plant J. (IF 7.2) Pub Date : 2024-02-27 Gwendolyn K. Kirschner
Striga is a parasitic plant that attacks the roots of crop plants, including sorghum, maize and rice, across Africa, India and Australia and causes economic damage of around 1 billion $US per year in Africa (Spallek et al., 2013). After germination, Striga attaches to the host roots with a specialised organ and takes up water and nutrients from the host, which can lead to a slow death of the host plants

SUMMARYApple rust is a serious fungal disease affecting Malus plants worldwide. Infection with the rust pathogen Gymnosporangium yamadae induces the accumulation of anthocyanins in Malus to resist rust disease. However, the mechanism of anthocyanin biosynthesis regulation in Malus against apple rust is still unclear. Here, we show that MpERF105 and MpNAC72 are key regulators of anthocyanin biosynthesis

Hydrotropism mechanisms and their interplay with gravitropism Plant J. (IF 7.2) Pub Date : 2024-02-23 Yonatan Wexler, Julian I. Schroeder, Doron Shkolnik
SUMMARYPlants partly optimize their water recruitment from the growth medium by directing root growth toward a moisture source, a phenomenon termed hydrotropism. The default mechanism of downward growth, termed gravitropism, often functions to counteract hydrotropism when the water‐potential gradient deviates from the gravity vector. This review addresses the identity of the root sites in which hy

Abort the mission: how shading triggers abortion of flower buds in sacred lotus Plant J. (IF 7.2) Pub Date : 2024-02-13 Martin Balcerowicz
Flowering at the appropriate time is vital for a plant's reproductive success. The formation of flowers is an energy-intensive process, and the plant must ensure that sufficient energy, usually in the form of sugars, is available to complete flowering and fruit production. In the model plant Arabidopsis thaliana, the onset of flowering is controlled by the presence of trehalose-6-phosphate, a metabolite

Rhizobial phosphatidylcholine (PC) is thought to be a critical phospholipid for the symbiotic relationship between rhizobia and legume host plants. A PC-deficient mutant of Sinorhizobium meliloti overproduces succinoglycan, is unable to swim, and lacks the ability to form nodules on alfalfa (Medicago sativa) host roots. Suppressor mutants had been obtained which did not overproduce succinoglycan and

Cortical cell size regulates root metabolic cost Plant J. (IF 7.2) Pub Date : 2024-02-10 Jagdeep Singh Sidhu, Jonathan P. Lynch
It has been hypothesized that vacuolar occupancy in mature root cortical parenchyma cells regulates root metabolic cost and thereby plant fitness under conditions of drought, suboptimal nutrient availability, and increased soil mechanical impedance. However, the mechanistic role of vacuoles in reducing root metabolic cost was unproven. Here we provide evidence to support this hypothesis. We first show

A carboxysome-based CO2 concentrating mechanism for C3 crop chloroplasts: advances and the road ahead Plant J. (IF 7.2) Pub Date : 2024-02-06 Nghiem D. Nguyen, Sacha B. Pulsford, Britta Förster, Sarah Rottet, Loraine Rourke, Benedict M. Long, G. Dean Price
The introduction of the carboxysome-based CO2 concentrating mechanism (CCM) into crop plants has been modelled to significantly increase crop yields. This projection serves as motivation for pursuing this strategy to contribute to global food security. The successful implementation of this engineering challenge is reliant upon the transfer of a microcompartment that encapsulates cyanobacterial Rubisco

The dual role of the RETINOBLASTOMA-RELATED protein in the DNA damage response is coordinated by the interaction with LXCXE-containing proteins Plant J. (IF 7.2) Pub Date : 2024-02-06 Jorge Zamora Zaragoza, Katinka Klap, Renze Heidstra, Wenkun Zhou, Ben Scheres
Living organisms possess mechanisms to safeguard genome integrity. To avoid spreading mutations, DNA lesions are detected and cell division is temporarily arrested to allow repair mechanisms. Afterward, cells either resume division or respond to unsuccessful repair by undergoing programmed cell death (PCD). How the success rate of DNA repair connects to later cell fate decisions remains incompletely

MdWER interacts with MdERF109 and MdJAZ2 to mediate methyl jasmonate- and light-induced anthocyanin biosynthesis in apple fruit Plant J. (IF 7.2) Pub Date : 2024-02-06 Xi Zhang, Lujia Yu, Mengjiao Zhang, Ting Wu, Tingting Song, Yuncong Yao, Jie Zhang, Ji Tian
Anthocyanin generation in apples (Malus domestica) and the pigmentation that results from it may be caused by irradiation and through administration of methyl jasmonate (MeJA). However, their regulatory interrelationships associated with fruit coloration are not well defined. To determine whether MdERF109, a transcription factor (TF) involved in light-mediated coloration and anthocyanin biosynthesis
