Melatonin (MT) regulates several physiological activities in plants. However, information on how MT regulates soybean growth under low-temperature (LT) stress is lacking. To better understand how MT promotes plant growth and development under LT stress, we designed this study to evaluate the role of MT pretreatment on soybean seedlings exposed to LT stress. Our results showed that LT stress increased oxidative damage by increasing reactive oxygen species (ROS) accumulation, which affected the growth and development of soybean seedlings. However, the application of 5 µmol L–1 MT significantly decreased the oxidative damage by increasing plant mineral element concentrations and the transcript abundance of antioxidant related genes, which enhanced the decrease in ROS accumulation. These results collectively suggest the involvement of MT in improving LT stress tolerance of soybean seedlings by mediating plant mineral elements and the expression of genes involved in the antioxidant pathway.

Potassium (K+) is one of essential mineral elements for plant growth and development. K+ channels, especially AKT1-like channels, play crucial roles in K+ uptake in plant roots. Maize is one of important crops; however, the K+ uptake mechanism in maize is little known. Here, we report the physiological functions of K+ channel ZMK1 in K+ uptake and homeostasis in maize. ZMK1 is a homolog of Arabidopsis AKT1 channel in maize, and mainly expressed in maize root. Yeast complementation experiments and electrophysiological characterization in Xenopus oocytes indicated that ZMK1 could mediate K+ uptake. ZMK1 rescued the low-K+-sensitive phenotype of akt1 mutant and enhanced K+ uptake in Arabidopsis. Overexpression of ZMK1 also significantly increased K+ uptake activity in maize, but led to an oversensitive phenotype. Similar to AKT1 regulation, the protein kinase ZmCIPK23 interacted with ZMK1 and phosphorylated the cytosolic region of ZMK1, activating ZMK1-mediated K+ uptake. ZmCIPK23 could also complement the low-K+-sensitive phenotype of Arabidopsis cipk23/lks1 mutant. These findings demonstrate that ZMK1 together with ZmCIPK23 plays important roles in K+ uptake and homeostasis in maize.

Low Sulfur

Vesicular-arbuscular mycorrhizae (VAM) generally enhances uptake and translocation of P and encourages plant growth and development in nutrient-deficient soils. Contradictory reports about the role of VAM in S uptake and translocation may result from insufficient consideration of soil S status. In this study, using soils of low S status, VAM inoculation increased the content of radioactively labelled S (35S) in shoots of maize plants.

Structural Levels

Plant hormones are master regulators of plant growth and development. Better knowledge of their spatial signaling and homeostasis (transport and metabolism) on the lowest structural levels (cellular and subcellular) is therefore crucial to a better understanding of developmental processes in plants. Recent progress in phytohormone analysis at the cellular and subcellular levels has greatly improved the effectiveness of isolation protocols and the sensitivity of analytical methods. This review is mainly focused on homeostasis of two plant hormone groups, auxins and cytokinins. It will summarize and discuss their tissue- and cell-type specific distributions at the cellular and subcellular levels.
