The quality of the seeds is of great importance for the cultivation of plants, however, the quality can be altered by the abiotic effects, amongst such, saline stress. Salinity is one of the great obstacles faced by modern agriculture, however, alternatives have been researched to mitigate its effects, where it is possible to mention the use of salicylic acid. The objective of this study was to evaluate the quality of basil (Ocimum basilicum L.) seeds cultivated using applications of salicylic acid to attenuate the irrigation water salinity. The experimental design was a completely randomized complete block design in incomplete factor scheme, with five conductivities for irrigation water (0.5, 1.3, 3.25, 5.2, 6.0 dS m -1 ) and five salicylic acid doses (0.0, 0.29, 1.0, 1.71 and 2.0 mM), with five and four replicates, respectively. The electrical conductivity presented an effect on germination, while the salicylic acid presented an effect on the germination speed index, emergence speed index, shoot length, root and seedling length, and seedlings dry mass. The highest correlations were obtained amongst the germination variables. Therefore, it is possible to affirm that salicylic acid can be used up to the dose of 1.0 mM with no further damage to basil seeds' quality.

Peer Review #2 of "iTRAQ-based quantitative proteome analysis reveals metabolic changes between a cleistogamous wheat mutant and its wild-type wheat counterpart (v0.2)"

Background: Wheat is one of the most important staple crops worldwide. Fusarium head blight severely affects wheat yield and quality. A novel bread wheat mutant, ZK001, characterised as cleistogamic was isolated from a non-cleistogamous variety (YM18) through static magnetic field mutagenesis. Cleistogamy is a promising strategy for controlling Fusarium head blight. However, little is known about the mechanism of cleistogamy in wheat. Methods: We performed a Fusarium head blight resistance test to identify the Fusarium head blight infection rate of ZK001. We also measured the agronomic traits of ZK001 and the starch and total soluble sugar contents of lodicules in YM18 and ZK001. Finally, we performed comparative studies at the proteome level between YM18 and ZK001 based on the proteomic technique of isobaric tags for relative and absolute quantification. Results: The infection rate of ZK001 was lower than that of its wild type and AK58. The abnormal lodicules of ZK001 lost the ability to push the lemma and palea apart during the flowering stage. Proteome analysis showed that the main differentially abundant proteins were related to carbohydrate metabolism, protein transport, and calcium ion binding. These differentially abundant proteins may work together to regulate cellular homeostasis, osmotic pressure and the development of lodicules. This hypothesis is supported by the analysis of starch, soluble sugar content in the lodicules as well as the results of qRT-PCR. Conclusions: Proteomic analysis has provided comprehensive information that should be useful for further research on the lodicule development mechanism in wheat. The ZK001 mutant is optimal for studying flower development in wheat and could be very important for Fusarium head blight resistant projects via conventional crossing.

“…Growth regulators, among them salicylic acid (SA), have been used to increase seed germination and seedling performance in different crops. The mechanisms by which the SA generates these improvements are related to the protection of cell membranes, increases in carbon metabolism, antioxidant system, osmoprotection and photosynthetic pigments (Sharma et al, 2017), and the regulation of stress defense proteins such as glutathione S-transferases, APX and 2-cysteine peroxiredoxin (Kang et al, 2012). Senaratna et al (2000) reported that seed priming with SA in tomato plants exposed to drought induced the capacity to retain a relatively high degree of turgidity and recovery upon watering.…”

Seed priming with salicylic acid potentiates water restriction-induced effects in tomato seed germination and early seedling growth

Seed priming with salicylic acid (SA) has been described as a method with potential to improve seed germination under unfavorable conditions. The present study aimed to evaluate the ability of seed priming with SA to attenuate the impact of water restriction during germination and early seedling growth of tomato. Seeds were subjected to different concentrations of SA (0, 25 and 50 µM) and sowed on substrates at different percentages of the water holding capacity (20, 30, 40 and 100%). The following variables were evaluated: germination, first count of germination, germination speed index, shoots/root length and dry mass, superoxide dismutase, ascorbate peroxidase and catalase activities, contents of hydrogen peroxide and of malondialdehyde. Water restriction significantly decreased the variables related to germination and seedling performance. Despite increasing germination speed and seedling development when combined with well-irrigated conditions, priming with SA negatively impacted those characteristics under water deficit conditions. That was through increases in superoxide dismutase activity and H2O2 accumulation. Thus, it was concluded that seed priming with SA does not improve tomato seed germination and early seedling growth under water deficit.
