“…In particular, NO was demonstrated to delay programmed cell death of barley aleurone cells by promoting the activity of antioxidant enzymes (Beligni et al, 2002). In addition, SNP, commonly used as NO-donor, was shown to alleviate heavy metal stress during seed germination of wheat (Hu et al, 2007), lupin (Kopyra and Gwóźdź, 2003) and rice (Péres da Rocha Oliveiros Marciano et al, 2010). Seed pre-incubation (seed priming) with SNP was also proved to increase salt stress tolerance in wheat (Duan et al, 2007; Zheng et al, 2009).…”

Germination ability is regulated by a combination of environmental and endogenous signals with both synergistic and antagonistic effects. Nitric oxide (NO) is a potent dormancy-releasing agent in many species, including Arabidopsis, and has been suggested to behave as an endogenous regulator of this physiological blockage. Distinct reports have also highlighted a positive impact of NO on seed germination under sub-optimal conditions. However, its molecular mode of action in the context of seed biology remains poorly documented. This review aims to focus on the implications of this radical in the control of seed dormancy and germination. The consequences of NO chemistry on the investigations on both its signaling and its targets in seeds are discussed. NO-dependent protein post-translational modifications are proposed as a key mechanism underlying NO signaling during early seed germination.

“…51 A number of experimental data globally indicates that the transition zone of the root may be considered as a sort of sensory center, enabling the root apex to continuously monitor environment parameters and to trigger appropriate responses. [51][52][53][54][55][56][57][58][59][60][61][62][63] Future studies will be needed to deepen the role of this unique root zone in translating the external stimuli in motoric responses.…”

To search for nutrients and water, roots need to efficiently explore large soil volumes. To this aim they generate complex root systems, allowing them to maximize their resource allocation efficiency. 1 Despite the vital importance of roots, the difficulty in accessing intact root systems for analysis, particularly under field conditions, have slowed down the breeding programs for plant's adaptation to environmental restrictions. 2,3 The capacity of plants to take up nutrients and water is mainly determined by changes in the architecture of the root system. 1 Three major processes affect the overall architecture of the root system: the rate of cell division, the rate of cell differentiation, and the extent of expansion and elongation of cells. [4][5][6] Disturbs in any of these 3 processes can affect the whole root-system architecture and the capacity of plants to survive and develop in adverse environments (Giehl et al. 7 and references therein).The root system results from the coordinated control of both genetic endogenous programs (regulating growth and organogenesis) and the action of abiotic and biotic environmental stimuli. 8,9 The dynamic control of the overall root system architecture (RSA) throughout time finally determines root plasticity and allows plants to efficiently adapt to environmental constraints. 10 The soil-environment from which plants extract nutrients and water is extremely heterogeneous, both spatially and temporally. 11 Among the nutrients present in soil, nitrate (NO 3 − ) may vary by an order of magnitude within centimeters or over the course of a day. 12 The effects of NO 3 − on the root system are complex and depend on several factors, such as the concentration available to the plant, the endogenous nitrogen status and the sensitivity of the species. 10,13,14 A considerable part of the studies aimed to unravel the mechanisms controlling RSA growth and development in response to nitrate have been focused on lateral roots (LR), 8,13,[15][16][17][18][19][20] while the nitrate-regulation of the primary root growth is still unclear. Beside NO 3 − , auxin has been demonstrated to strongly affect and control the LR development, [21][22][23][24] and an increasing number of studies suggests an overlap between auxin and NO 3 − signaling pathways in controlling LR development. [25][26][27][28][29][30][31][32][33] NO 3 -has a Doubtful Role in Regulating the Growth of Primary RootsDespite the high amount of reports published on nitrate effects on root elongation, the lack of univocal results makes it difficult to clearly decipher this response ( Table 1). In Arabidopsis thaliana, inhibition of primary root growth has been observed when nitrate is applied homogeneously at high concentrations (50 mM) for 7 d, but not in a range between 0.1 and 10 mM. 35 On the contrary, in this same species Linkohr et al. 36 showed an inhibition of primary root elongation with the increase of nitrate concentration already beyond 0.01 mM, but in this case seedlings were IAA, indole-3-acetic acid; SNP, sodium n...

“…In recent decades, the acidi cation of soil has become more problematic because of the excessive application of ammonium fertilizer and the increase in acid rain. Studies have proven that excess Al 3+ content in acid soil can inhibit cellular activity in root meristem, prevent mitosis, and retard root growth (Doncheva et al 2005;Marciano et al 2010). A healthy root system is crucial for providing anchorage, the intake of water and nutrients, sensing environmental signals, and interacting with the soil microbiome (Tracy et al 2020).…”

Aluminum (Al) toxicity has become one of the important abiotic stress factorsin areas with acid soil, which hinders the absorption of water and nutrients by roots, and consequently retards the growth of crops. A deeper understanding of the stress response mechanism of Brassica napus may allow us to identify the tolerance gene(s) and use this information in breeding resistant crop varieties. In this study, a population of 138 recombinant inbred lines (RILs) was subjected to aluminum stress, and QTL (quantitative trait locus) mapping was used to preliminarily locate quantitative trait loci related to aluminum stress. Root tissues from seedlings of aluminum-resistant (R) lines and aluminum-sensitive (S) lines from the RIL population were harvested for transcriptome sequencing and metabolome determination. By combining the data on quantitative trait genes (QTGs), differentially expressed genes (DEGs), and differentially accumulated metabolites (DAMs), key candidate genes related to aluminum tolerance in rapeseed were determined. The results showed that there were 3186 QTGs in the RIL population, 14,232 DEGs and 457 DAMs in the comparison between R and S lines. Lastly, 138 hub genes were selected to have a strong positive or negative correlation with 30 important metabolites (|R|≥0.95). These genes were mainly involved in the metabolism of lipids, carbohydrates, and secondary metabolites in response to Al toxicity stress. In summary, this study provides an effective method for screening key genes by combining QTLs, transcriptome sequencing, and metabolomic analysis, but also lists key genes for exploring the molecular mechanism of Al tolerance in rapeseed seedling roots.
