You said ‘the aim of this review is to present a recapitulation of the latest advances concerning the exogenous application of selected naturally-occurring organic acids (OAs) to crops, the chemical structures of which are shown in Table 1. In each case, their effects at morphological, physiological and molecular levels, and how exogenous supplementation has been used in crop species to mitigate the effects of excess HM levels, are discussed.’

Reviewer 2 Report

I recommend that authors should focus on the detailed mechanisms involved regarding the heavy metals tolerance by exogenous application of organic acids. Moreover, authors should cite more studies and must focus on the recent ones.

Reviewer 3 Report

Title of manuscript to accept

 

From what I’ve read, the manuscript seems to be very good

But ....

1. 53 - Please add paper about photosynthesis ..

The soil composition is / was the primary factor affecting chlorophyll fluorescence (CF) parameters......

.....redirection of photosynthates towards protective mechanisms against toxic effects of metals.

for instance

Bączek-Kwinta R., Antonkiewicz J., Łopata-Stasiak A., Kępka W. 2019. Smoke compounds aggravate stress inflicted on Brassica seedlings by unfavourable soil conditions. Photosynthetica, 57, 1, 1-8. DOI: 10.32615/ps.2019.026

 

Please add figure about effect of heavy metals on physiological parameters .....
