Triose phosphate export from chloroplasts and cellular sugar content regulate anthocyanin biosynthesis during high light acclimation

Max-Emanuel Zirngibl et al.

Summary: Plants use multiple strategies to adapt to rapid environmental changes, and during high light acclimation, the biosynthesis of photoprotective flavonoids is induced through carbon fixation, export of photosynthates, and an increase in cellular sugar content. Reactive oxygen species and phytohormones play a minor role, while sugar signaling is vital for the activation of anthocyanin biosynthesis.

Interplay between ethylene and nitrogen nutrition: How ethylene orchestrates nitrogen responses in plants

Biao Ma et al.

Summary: The stress hormone ethylene plays a key role in plant adaptation to adverse environmental conditions. Changes in nitrogen availability or forms can affect ethylene biosynthesis and signaling. Ethylene serves as a cellular signal to mediate various physiological responses, including root system architecture adaptation, nitrogen uptake and translocation, ammonium toxicity, anthocyanin accumulation, and premature senescence. Specifically, in rice, ethylene is essential for its survival under hypoxic conditions.

Physiological and molecular response of colored wheat seedlings against phosphate deficiency is linked to accumulation of distinct anthocyanins

Satveer Kaur et al.

Summary: Anthocyanin rich colored wheat has attracted attention for its potential in addressing malnutrition and its differential response to phosphorus deficiency. This study investigated how different colored wheat genotypes adapt to phosphorus stress and found that the black wheat genotype with the highest anthocyanin content showed the best adaptation. This research has implications for the future cultivation practices in agriculture.

The SLIM1 transcription factor affects sugar signaling during sulfur deficiency in Arabidopsis

Anna Wawrzynska et al.

Summary: The homeostasis of major macronutrient metabolism, particularly sulfur metabolism and glucose signaling, play important roles in plant growth and stress responses. This study demonstrates that the transcription factor SLIM1 is involved in glucose signaling during sulfur deficiency in Arabidopsis, affecting germination rate and gene expression. SLIM1 modulates sulfur metabolism and directly controls PAP1 expression, leading to changes in anthocyanin production under sulfur deficiency stress.

Activation of anthocyanin biosynthesis in high light - what is the initial signal?

Galileo Estopare Araguirang et al.

Summary: Due to their immobile nature, plants have evolved mechanisms to cope with sudden environmental changes. The acclimation response to abiotic factors affects cellular functions at all levels and involves rapid modifications of enzymatic activities, the metabolome, proteome, and transcriptome. When acclimating to high light (HL), plants rapidly activate the flavonoid biosynthesis (FB) pathway to accumulate photoprotective and antioxidative flavonoids in leaf tissue. The signals and signaling pathways regulating the conditional activation of FB in HL are still debated.

The involvement of abscisic acid-insensitive mutants in low phosphate stress responses during rhizosphere acidification, anthocyanin accumulation and Pi homeostasis in Arabidopsis

Kai Jian Lei et al.

Summary: Phosphorus is an essential nutrient for plants and the hormone abscisic acid (ABA) may play a role in plant responses to low phosphorus stress. This study investigated ABA-insensitive Arabidopsis mutants under low phosphorus stress and found that they exhibited different phenotypic characteristics, including enhanced rhizosphere acidification, altered anthocyanin accumulation, and changes in phosphorus uptake and transportation. Further research showed that ABI5 regulated the expression of PHT1;5 and WRKY42 by binding to their promoters.

The apple BTB protein MdBT2 positively regulates MdCOP1 abundance to repress anthocyanin biosynthesis

Hui Kang et al.

Summary: The study reveals that MdBT2 interacts with and stabilizes MdCOP1 protein in apple, leading to repression of anthocyanin biosynthesis. MdBT2 enhances the ubiquitination and degradation of the transcription factor MdMYB1 mediated by MdCOP1, resulting in the inhibition of anthocyanin biosynthesis gene expression and anthocyanin accumulation.

SPX4 interacts with both PHR1 and PAP1 to regulate critical steps in phosphorus-status-dependent anthocyanin biosynthesis

Yuqing He et al.

Summary: Phosphate is the plant-accessible form of phosphorus, and its deficiency limits plant growth. Studies show that phosphate deficiency can lead to over-accumulation of anthocyanins in plants, and SPX4 plays a role in transmitting the phosphate starvation signal to anthocyanin biosynthesis pathways.

The apple 14-3-3 protein MdGRF11 interacts with the BTB protein MdBT2 to regulate nitrate deficiency-induced anthocyanin accumulation

Yi-Ran Ren et al.

Summary: This study revealed that MdBT2 undergoes posttranslational modifications in response to nitrate deficiency, and interacts with MdGRF11, a 14-3-3 protein, which negatively regulates the stability of MdBT2 protein via a 26S proteasome-dependent pathway. This leads to increased abundance of MdMYB1 proteins and activation of anthocyanin biosynthesis-related genes. The results demonstrate the critical role of 14-3-3 proteins in the regulation of nitrate deficiency-induced anthocyanin accumulation.

Jasmonate induces biosynthesis of anthocyanin and proanthocyanidin in apple by mediating the JAZ1-TRB1-MYB9 complex

Jian-Ping An et al.

Summary: This study revealed the interaction between the apple telomere-binding protein MdTRB1 and MdMYB9 in regulating the accumulation of anthocyanin and proanthocyanidin. Furthermore, it was found that the JA signaling repressor MdJAZ1 interfered with the interaction between MdTRB1 and MdMYB9, leading to a negative modulation of the biosynthesis of anthocyanin and proanthocyanidin.

Dynamic Nutrient Signaling Networks in Plants

Lei Li et al.

Summary: This article reviews the multifaceted roles of nutrients in plants, discussing the regulation of signaling networks by sugars, nitrate, and phosphate, as well as key regulators newly discovered. The paper highlights the dynamic nutrient, energy, growth, and stress signaling networks that coordinate systemwide transcriptional, translational, and metabolic reprogramming and respond to environmental stimuli.

Photoprotection of Arabidopsis leaves under short-term high light treatment: The antioxidant capacity is more important than the anthocyanin shielding effect

Zheng-Chao Yu et al.

Summary: Plants have evolved photoprotection strategies to cope with high light stress, with antioxidant capacity being the major mechanism of plant photoprotection against short-term high light stress. Plants with high antioxidant capacity show higher resistance to short-term high light stress, while those with lower antioxidant capacity exhibit lower resistance.
