“…Moreover, in the significant group, Pi starvation caused a decrease in anthocyanins differing from the results of previous studies [ 20 ]. In a recent study, the common physiological responses of Pi deficiency and ethylene were summarized in four categories involving acidification, nutrient transporters, phosphatase, chelating agents, and other compounds, with different genes involved in the different categories [ 31 ]. Induction of Pi by ethylene alone is not sufficient, and the presence of specific signals related to P in plants is abundant [ 32 ].…”

Chinese fir (Cunninghamia lanceolata (Lamb.) Hook) is a widely grown gymnosperm in China. Phosphorus (P) is an indispensable nutrient for the growth of Chinese fir. Inorganic phosphate (Pi) deficiency exists in soils of many Chinese fir planting area regions, and the trees themselves have limited efficiency in utilizing P from the soil. Ethylene is important in regulation responses to nutrient deficiencies. However, little is known about how ethylene signals participate in Pi stress in Chinese fir. A total of six different treatments were performed to reveal the transcript levels of Chinese fir under Pi, ethephon (an ethylene-releasing compound), and CoCl2 (cobalt chloride, an ethylene biosynthesis inhibitor) treatments. We assembled a full-length reference transcriptome containing 22,243 unigenes as a reference for UMI RNA-seq (Digital RNA-seq). There were 586 Differentially Expressed Genes (DEGs) in the Pi starvation (NP) group, while DEGs from additional ethephon or CoCl2 in NP were 708 and 292, respectively. Among the DEGs in each treatment, there were 83 TFs in these treatment groups. MYB (v-myb avian myeloblastosis viral oncogene homolog) family was the most abundant transcription factors (TFs). Three ERF (Ethylene response factor) family genes were identified when only ethylene content was imposed as a variable. Enrichment analysis indicated that the ascorbate and aldarate metabolism pathway plays a key role in resistance to Pi deficiency. This study provides insights for further elucidating the regulatory mechanism of Pi deficiency in Chinese fir.

“…As previously stated, to cope with nutrient deficiencies plants can develop physiological and morphological responses, mainly in roots, aimed to facilitate the acquisition of the deficient nutrient(s) (Shin, 2011;Kobayashi and Nishizawa, 2012;Zhang et al, 2014;García et al, 2015García et al, , 2021aRomera et al, 2021). Following are some of the most frequent physiological and morphological responses.…”

“…Physiological responses include acidification of the rhizosphere; increased expression of specific nutrient transporters, both at the root epidermis and in other tissues; increased synthesis and/or release of chelating agents into the medium (to improve mobilization of nutrients in the soil and/or inside the plant); increased expression of transporters associated with the release of different compounds to the medium; enhancement of some root enzymatic activities, like ferric reductase activity and phosphatase activity; and others (Zhang et al, 2014;García et al, 2015García et al, , 2021aLucena et al, 2015Lucena et al, , 2019Romera et al, 2021).…”

“…Terrestrial plants are sessile organisms that have to continuously change their physiology and morphology to adapt to the availability of different nutrients in the soil. To cope with nutrient deficiencies, they can adopt several strategies (Romera et al, 2021), like to stop growth ("stop growing" strategy), to limit the demand of nutrients (Marschner et al, 1996;Shin, 2011;Marzec and Melzer, 2018); to develop physiological and morphological responses ("searching for nutrients" strategy), to facilitate the acquisition of the deficient nutrient(s) (Kobayashi and Nishizawa, 2012;Zhang et al, 2014;García et al, 2015;Romera et al, 2021); to recycle the deficient nutrient(s) from the oldest leaves and organs to the youngest ones (Masclaux-Daubresse et al, 2017;Chen et al, 2019); and to substitute the deficient nutrient(s) by other(s) that can play a similar role (Wakeel et al, 2011;Lambers et al, 2012;Waters et al, 2012). These different strategies are not incompatible between them and can occur simultaneously.…”

“…In plants, although less studied, the TOR pathway integrates hormonal and nutritional signals to regulate plant growth and development (Robaglia et al, 2012;Barrada et al, 2015;Dobrenel et al, 2016a;Rosenberger and Chen, 2018;Ryabova et al, 2019;Wu et al, 2019;Fu et al, 2020). In relation to the "searching for nutrients" strategy, it is known that plants can develop morphological and physiological responses, mainly in their roots, aimed to facilitate mobilization and acquisition of the deficient nutrient(s) (Zhang et al, 2014;García et al, 2015García et al, , 2021aRomera et al, 2021). These responses are activated when plants suffer from a nutrient deficiency and are switched off once the nutrient has been acquired in sufficient quantity.…”

To grow or not to grow under nutrient scarcity: Target of rapamycin-ethylene is the question

To cope with nutrient scarcity, plants generally follow two main complementary strategies. On the one hand, they can slow down growing, mainly shoot growth, to diminish the demand of nutrients. We can call this strategy as “stop growing.” On the other hand, plants can develop different physiological and morphological responses, mainly in their roots, aimed to facilitate the acquisition of nutrients. We can call this second strategy as “searching for nutrients.” Both strategies are compatible and can function simultaneously but the interconnection between them is not yet well-known. In relation to the “stop growing” strategy, it is known that the TOR (Target Of Rapamycin) system is a central regulator of growth in response to nutrients in eukaryotic cells. TOR is a protein complex with kinase activity that promotes protein synthesis and growth while some SnRK (Sucrose non-fermenting 1-Related protein Kinases) and GCN (General Control Non-derepressible) kinases act antagonistically. It is also known that some SnRKs and GCNs are activated by nutrient deficiencies while TOR is active under nutrient sufficiency. In relation to the “searching for nutrients” strategy, it is known that the plant hormone ethylene participates in the activation of many nutrient deficiency responses. In this Mini Review, we discuss the possible role of ethylene as the hub connecting the “stop growing” strategy and the “searching for nutrients” strategy since very recent results also suggest a clear relationship of ethylene with the TOR system.
