“…As mentioned above, the five known 10,11- seco -lathyrane diterpenes were all isolated from Jatropha species. The plants from Jatropha , such as J. curcas , commonly grow on barren lands in tropical and subtropical regions, which often have acidic soils with high aluminum content. , We supposed that highly reactive naturally abundant lathyrane diterpenes might be changed to produce the minor component 10,11- seco -lathyranes under the acid environment. To test this hypothesis, lathyrane type diterpene lathyrol I was exposed to various kinds of natural organic acids (including citric acid, tartaric acid, oxalic acid, malic acid, benzoic acid, and acetic acid) to mimic a weakly acidic natural environment (Supporting Information, SI, Table S1).…”

The question of whether rare 10,11-seco-lathyranes are natural products or artifacts is thoughtfully considered after a Brønsted acid-mediated chemical conversion of naturally abundant 5/11/3 lathyrane type diterpenes into 10,11-seco-lathyranes was developed. Benefiting from this concise route, a series of 10,11seco-lathyrane products (1−14) were smoothly synthesized. The conversion may involve an acid promoted cyclopropane ring opening accompanied by a double bond shift with final trapping of carbocation. The ease of this chemical conversion under mildly acidic conditions may imply that the 10,11-seco-lathyranes isolated to date are artifacts. This work not only develops a new modular synthetic strategy for efficient constructing rare 10,11-seco-lathyranes, but also provides a promising bioactive diterpene with excellent effect against the NO production on LPS-induced BV-2 cells.

“…Aluminum can cause toxicity in the embryonic axis of the seeds, compromising cell division and/or cell elongation, and subsequently, the appearance of abnormal seedlings (Ranal et al, 2016). However, the main effect is seen on the roots, and its length is the first parameter indicated to study in ecotoxicological tests (Senger et al, 2014).…”

The varieties creole are traditionally grown plant, adapted in places where the crops are developed and present in seeds banks of many famers. Thus the objective of this study was to investigate the performance of the germination process and possible toxic effects. Were used seeds of creole cultivars of beans (Phaseolus vulgaris L.), using different concentrations of aluminum. We used a randomized completely design with four repetitions of 25 seeds and the treatments were distributed in 4 x 5 factorial scheme, consisting of four bean cultivars (Carioca, Butter, Black, Red) and five concentrations (0.0, 2.5, 5.0, 7.5, and 10.0 mg L-1) of aluminum sulfate. The characteristics analyzed were percentage of germination, percentage of abnormal seedlings, germination speed index, root length, length of the base of the seedling to the hypocotyl, hypocotyl length of seedlings to the epicotyl, root dry mass and shoot dry mass. The variables germination percentage and germination speed index were not affected by the toxic effect of aluminum. The variables percentage of abnormal seedlings, root length and shoot showed a significant reduction with the increase in aluminum sulfate concentrations, thus showing a greater correlation between them.

“…Acidic soil is widely distributed in tropical and subtropical areas of the world and accounts for approximately 30% of the total area and 50% of the arable land in the world (Sade et al, 2016; Senger et al, 2014). Due to climate‐ and human‐related factors, such as industrial emissions, unreasonable land use, and acid rain, the area of acidic soils is still expanding annually (Bojórquez et al, 2017).…”

“…At pH < 5.5, Al is easily converted to ions that can be absorbed by plants and then severely inhibit their growth and development (Matsumoto, 2000). Therefore, Al‐tolerant plants must be cultivated to improve crop production (Senger et al, 2014).…”

Responses of mineral nutrient contents and transport in red clover under aluminum stress

et al. 2021

Aluminum toxicity is considered the main factor underlying nutrient deficiencies and growth limitations of plants in acidic soil. Red clover (Trifolium pratense L.) is an important legume grass distributed worldwide, and it has medicinal value and strong adaptability to acidic soil with Al. However, few studies have focused on the relationship between nutrient uptake and Al stress. In this study, the changes in nutrients in the organs (root, stem, and leaf) of the cultivars Brilliant, Dory, and Haifa under high aluminum stress were detected. The results indicated that the contents of macronutrients and micronutrients were significantly influenced by Al3+ concentrations and the interaction between Al3+ concentrations and cultivars (P < 0.05). Under the Al3+ treatments, the contents of phosphorus (P) and magnesium (Mg) significantly decreased by 30.5% to 87.2% and 6.3% to 39.2%, respectively. However, potassium (K), zinc (Zn), and manganese (Mn) increased significantly, and these changes were closely correlated with Al resistance. The effect of Al stress on the copper (Cu) content varied with the plant organs, with Cu reduced in the roots but increased in the stems and leaves. Furthermore, the change ranges of nutrition contents in the sensitive cultivar were largest except for Cu. For example, the contents of Ca dropped by 26% in Brilliant leaves but decreased by less than 4% in the leaves of Haifa and Dory at 5‐mM Al3+. Moreover, the nutrient transport efficiencies were positively correlated with the Al3+ treatment concentrations in resistant cultivar except for Mg.
