“…There exist more than 40 TFs that act downstream of photoreceptor genes in Arabidopsis [168]. The TFs regulating starch biosynthesis have been also identified in rice [169][170][171][172][173][174], maize [175][176][177][178], barley [179], cassava [180,181], Panicum virgatum [182], sweet potato [183], and Arabidopsis [184][185][186][187]. It is noteworthy that a rice nuclear factor Y (NF-Y) TF complex activates GBSSI to regulate the grain quality of rice [188].…”

C and N are the most important essential elements constituting organic compounds in plants. The shoots and roots depend on each other by exchanging C and N through the xylem and phloem transport systems. Complex mechanisms regulate C and N metabolism to optimize plant growth, agricultural crop production, and maintenance of the agroecosystem. In this paper, we cover the recent advances in understanding C and N metabolism, regulation, and transport in plants, as well as their underlying molecular mechanisms. Special emphasis is given to the mechanisms of starch metabolism in plastids and the changes in responses to environmental stress that were previously overlooked, since these changes provide an essential store of C that fuels plant metabolism and growth. We present general insights into the system biology approaches that have expanded our understanding of core biological questions related to C and N metabolism. Finally, this review synthesizes recent advances in our understanding of the trade-off concept that links C and N status to the plant’s response to microorganisms.

“…In sweet potato, a DOF protein called SRF1 was found to have an indirect positive effect on starch synthesis (Tanaka et al 2009) (Fig 2). In switchgrass, PvBMY1 (BioMass Yield 1) and PvBMY3 (BioMass Yield 3) regulate photosynthesis and starch synthesis (Ambavaram et al 2018). In Arabidopsis, BAM5 is regulated by two TFs, WRKY DNA-binding domain 75 (WRKY75, At5g13080) and NAC domain-containing protein 96 (NAC096, At5g46590) (Bumee et al 2013) (Fig 2).…”

Biological networks are complex (non-linear), redundant (cyclic) and compartmentalized at the subcellular level. Rational manipulation of plant metabolism may have failed due to inherent difficulties of a comprehensive understanding of regulatory loops. We first need to identify key factors controlling the regulatory loops of primary metabolism. The paradigms of plant networks are revised in order to highlight the differences between metabolic and transcriptional networks. Comparison between animal and plant transcription factors (TFs) reveal some important differences. Plant transcriptional networks function at a lower hierarchy compared to animal regulatory networks. Plant genomes contain more TFs than animal genomes, but plant proteins are smaller and have less domains as animal proteins which are often multifunctional. We briefly summarize mutant analysis and co-expression results pinpointing some TFs regulating starch enzymes in plants. Detailed information is provided about biochemical reactions, TFs and cis regulatory motifs involved in sucrose-starch metabolism, in both source and sink tissues. Examples about coordinated responses to hormones and environmental cues in different tissues and species are listed. Further advancements require combined data from single-cell transcriptomic and metabolomic approaches. Cell fractionation and subcellular inspection may provide valuable insights. We propose that shuffling of promotorpromoter elements might be a promising strategy to improve in the near future starch content, crop yield or food quality.

“…Так, установлено, что у трансгенных растений табака с более быстрым восстановлением от фотоингибирования на 15-20 % возрастала масса сухого вещества [16,17]. Показано также, что увеличение экспрессии генов, влияющих на регуляцию фотосинтеза и связанного с ним метаболизма, у трансгенных растений проса приводило к значительному (на 60 % по сравнению с диким типом) увеличению надземной биомассы [18]. При этом среди трансгенных линий были идентифицированы линии с повышенной скоростью транспорта электронов фотосистем I и II, а также с повышенным уровнем крахмала и водорастворимых сахаров [18].…”

Кроме того, положительное влияние увеличения биомассы надземной части растений на ранних этапах на урожайность может быть обусловленным и пролонгированным взаимодействием генов.…”

Aim. The search of factors influencing grain productivity, based on the comparison of the mass of dry matter in the aboveground parts of modern winter wheat varieties at the early stages of ontogenesis. Methods. Morphometric determination of biomass of the above-ground plant parts. Results. The varieties and lines of winter wheat with higher yields exceeded the less productive ones by the number of shoots per 1 m2 of soil on 8–12 % and by the dry matter weight of the above-ground plant parts on 23–34 % at the early stages of spring vegetation. According to two-year experiments, it was established a linear positive correlation (r = 0.85–0.86) of the dry matter weight of the above-ground plant parts per 1 m2 of soil during the period of stem elongation (BBCH 31-49) with the yield. Conclusions. The close relationship between yield and dry matter weight of the above-ground plant parts at the early stages of spring vegetation makes it possible to rank winter wheat varieties by potential yield. Keywords: Triticum aestivum L., grain productivity, biomass, early stages of ontogenesis.
