Two maize homologs of mammalian proton-coupled folate transporter, ZmMFS_1-62 and ZmMFS_1-73, are essential to salt and drought tolerance.

Folates are essential to the maintenance of normal life activities in almost all organisms. Proton-coupled folate transporter (PCFT), belonging to the major facilitator superfamily, is one of the three major folate transporter types widely studied in mammals. However, information about plant PCFTs is limited.

MrERF039 transcription factor plays an active role in the cold response of Medicago ruthenica as a sugar molecular switch.

Cold stress severely restricts plant development, causing significant agricultural losses. We found a critical transcription factor network in Medicago ruthenica was involved in plant adaptation to low-temperature. APETALA2/ethylene responsive factor (AP2/ERF) transcription factor MrERF039 was transcriptionally induced by cold stress in M.

Liquid-liquid phase separation in plants: Advances and perspectives from model species to crops.

Membraneless biomolecular condensates play important roles in both normal biological activities and responses to environmental stimuli in living organisms. Liquid‒liquid phase separation (LLPS) is an organizational mechanism that has emerged in recent years to explain the formation of biomolecular condensates. In the past decade, advances in LLPS research have contributed to breakthroughs in disease fields.

The histone methyltransferase SUVR2 promotes DSB repair via chromatin remodeling and liquid-liquid phase separation.

Maintaining genomic integrity and stability is particularly important for stem cells, which are at the top of the cell lineage origin. Here, we discovered that the plant-specific histone methyltransferase SUVR2 maintains the genome integrity of the root tip stem cells through chromatin remodeling and liquid-liquid phase separation (LLPS) when facing DNA double-strand breaks (DSBs). The histone methyltransferase SUVR2 (MtSUVR2) has histone methyltransferase activity and catalyzes the conversion of histone H3 lysine 9 monomethylation (H3K9me1) to H3K9me2/3 in vitro and in Medicago truncatula.

Melatonin Enhances Seed Germination and Seedling Growth of Under Salinity a Putative Melatonin Receptor .

Alfalfa ( L.) is an important forage crop, and salt stress is a major limiting factor in its yield. Melatonin (MT) is a multi-regulatory molecule in plants.

Corrigendum: Ethylene Enhances Seed Germination and Seedling Growth Under Salinity by Reducing Oxidative Stress and Promoting Chlorophyll Content ETR2 Pathway.

Ethylene Enhances Seed Germination and Seedling Growth Under Salinity by Reducing Oxidative Stress and Promoting Chlorophyll Content ETR2 Pathway.

Alfalfa ( L.) is an important forage, and salinity is a major stress factor on its yield. In this study, we show that osmotic stress retards alfalfa seedling growth, while ionic/oxidative stress reduces its seed germination.

Molecular characterisation and expression analysis of NAC transcription factor genes in wild Medicago falcata under abiotic stresses.

The No apical meristem-Arabidopsis transcription activation factor-Cup-shaped cotyledon (NAC) proteins play vital roles in plant development processes and responses to abiotic stress. In this study, 146 unigenes were identified as NAC genes from wild Medicago falcata L. by RNA sequencing.

miR403a and SA Are Involved in Mediated Antiviral Defenses Against TMV Infection in .

RNAi (RNA interference) is an important defense response against virus infection in plants. The core machinery of the RNAi pathway in plants include DCL (Dicer Like), AGO (Argonaute) and RdRp (RNA dependent RNA polymerase). Although involvement of these RNAi components in virus infection responses was demonstrated in , their contribution to antiviral immunity in , a model plant for plant-pathogen interaction studies, is not well understood.

Functional Analysis of Ion Transport Properties and Salt Tolerance Mechanisms of RtHKT1 from the Recretohalophyte Reaumuria trigyna.

Reaumuria trigyna is an endangered recretohalophyte and a small archaic feral shrub that is endemic to arid and semi-arid plateau regions of Inner Mongolia, China. Based on transcriptomic data, we isolated a high-affinity potassium transporter gene (RtHKT1) from R. trigyna, which encoded a plasma membrane-localized protein.

Cloning and characterization of a Ca(2+)/H(+) exchanger from the halophyte Salicornia europaea L.

The calcium ion (Ca(2+)), which functions as a second messenger, plays an important role in plants' responses to various abiotic stresses, and Ca(2+)/H(+) exchangers (CAXs) are an important part of this process. In this study, we isolated and characterized a putative Ca(2+)/H(+) exchanger gene (SeCAX3) from Salicornia europaea L., a succulent, leafless euhalophyte.

Isolation and characterization of two Medicago falcate AP2/EREBP family transcription factor cDNA, MfDREB1 and MfDREB1s.

DREB transcription factors play an important role in tolerance to abiotic stress in high plants. In this work, two new DRE-binding protein genes MfDREB1 and MfDREB1s cDNA that encoded an AP2/EREBP type transcription factor were isolated by RT-PCR from Medicago falcate seedlings. Sequence analysis showed MfDREB1 and MfDREB1s were almost identical except that there was a 202bp fragment at the 3' end of the MfDREB1s cDNA that is absent in MfDREB1 cDNA.

Transformation of a marker-free and vector-free antisense ACC oxidase gene cassette into melon via the pollen-tube pathway.

Melons have short shelf-lives due to fruit ripening caused by ethylene production. The 1-aminocyclopropane-1-carboxylic acid (ACC) oxidase gene is essential for ethylene biosynthesis. As fruit ripening in other fruit crops can be deterred by down-regulation of ACC oxidase expression, we have carried out similar work to improve fruit quality and shelf-life of the melon Cucumis melo.
