“…A water-soluble lectin, robin, initially discovered in black locust inner bark (Jones et al 1925), is presumably toxic to cattle, horses, and humans (Homo sapiens L.) which consume the plant (Hui et al 2004). The flavonoid acacetin, obtained from a whole-tree extract of black locust, is cytotoxic to a human tumor cell line (Tian and McLaughlin 2000).…”

Ranchers need alternative livestock feeds when herbaceous forages become limiting in summer. Our objectives were to determine: (1) leaf and stem biomass components, (2) nutritive value [in vitro dry matter digestibility (IVDMD), total nonstructural carbohydrate (TNC), N, and N digestibility] of leaves for animal browse, (3) concentration of the secondary metabolites robinin and mimosine, and (4) in vitro leaf and bark toxicity for black locust (Robinia pseudoacacia L.) and mimosa (Albizia julibrissin Durz.), respectively, pollarded at 50 cm in Arkansas, USA.Black locust exceeded mimosa for every yield component (leaf mass tree -1 , leaves shoot -1 , shoots tree -1 , shoot mass tree -1 , stem basal area, and biomass tree -1 ) except mass leaf -1 . Projected yields were 1,900 and 1,600 kg leaves ha -1 for black locust and mimosa, respectively, assuming a population of 12,300 trees ha -1 . Mimosa leaves had greater IVDMD, TNC, and N digestibility than black locust. Mimosa leaves exceeded the nutritional N requirements of growing cattle (Bos taurus L.) and goats (Capra hircus L.), but protein supplementation would be needed for growing goats grazing black locust leaves. Tissue concentrations of secondary metabolites robinin and mimosine were below detectable limits in black locust and mimosa, respectively. The extract of black locust bark, but not leaves, was toxic to bioassayed African green monkey (Cercopithecus aethiops L.) cells. Either black locust or mimosa could provide moderate quantities of high quality, rotationally grazed forage for goats during summer months when herbaceous forage may in short supply.

“…This phenomenon might be explained by the allelopathic effect of black locust, which can produce and release secondary metabolites (e.g. toxalbumins, robin and phasin) that can reveal inhibition effects on protein synthesis that certain species cannot tolerate (Hui et al 2004;Rahmonov 2009;Lazzaro et al 2018). Community structure as emphasized by the CDI index is more evenly distributed among species in the native sessile oak plots, while the few eudominants with higher abundance and the majority of species at relatively low numbers in the black locust plantation might also reflect unfavourable conditions for certain groups of Collembola.…”

Impact of former long-term fertilization on springtail communities in a reforested experimental area

At the beginning of the 1970's, two fertilization experimental areas were established in Gödöllő. After different long-term fertilization treatments, sessile oak (Quercus petraea) and black locust (Robinia pseudoacacia) plantations were planted in the second half of the 1990's. In the present research, the effects of former fertilization were studied in these two different forests, with the help of soil Collembola communities as indicators. Soil cores and litter samples were collected from the chosen 30 plots to determine the most important soil parameters and to extract Collembola specimens. According to the results, soil organic carbon (SOC), AL-P 2 O 5 and AL-K 2 O contents were significantly higher in the two highest-dose treatments of the sessile oak plantation compared to the control. In the black locust plantation, only AL-P 2 O 5 content differed significantly in the second highest-dose treatment when compared to the control. Among the two plantations significant differences can be observed in almost every parameter, except for AL-K 2 O and nitrogen content. The effects of former fertilizer application are reflected in occasional differences in total Collembola abundance, species richness and diversity, mostly related to the treatments with the highest doses. Due to the relatively young age of the plantations, very few typical forest Collembola species were observed, while species characteristic for open habitats are still predominant. The higher SOC content in the black locust plots is well reflected in the higher Collembola abundance compared to the sessile oak plots. Nevertheless, species richness, diversity and equitability were higher in the plantations of the native sessile oak.

“…10 In an orphanage where 32 children ate bark from the black locust, the clinical presentation included vomiting, mild hematemesis, pallor, peripheral cyanosis, dilated pupils, and stupor. 13 The vomiting began about 2 1 / 2 hours after chewing the bark, and the vomiting responded to anti -emetic medication. There were no fatalities.…”

Black locust (Robinia pseudoacacia L.) is an easy to raise, fast growing, medium-sized deciduous tree species highly tolerant to harsh eco-conditions, i.e., drought and harsh winters , and it is widely adaptable to sandy, loamy, and marshy soils. The basis for this adaptability remains to be investigated at the transcriptomic level using real-time quantitative PCR (qPCR). Selection of a reliable gene for the normalization of qPCR data is important for obtaining accurate results in gene expression. The goal of this study was to identify an appropriate reference gene from 12 candidate genes for gene expression analysis in black locust exposed to various stressors such as abscisic acid (ABA), NaCl, polyethylene glycol (PEG) and varying temperatures. In GeNorm and NormFinder analyses, ACT (actin) and GAPDH (glyceraldehyde-3-phosphate dehydrogenase) gene expression were the most stable in all conditions except heat stress, but in BestKeeper analysis, GAPDH and helicase gene expression were the most stable under NaCl and heat stress. In contrast, ACT and GAPDH were highest under abscisic acid (ABA), GAPDH and βTUB (beta tubulin) under cold stress, and helicase and EF1α (elongation factor 1 alpha) under PEG stress. We found that the most stable reference gene combination for all conditions was ACT and GAPDH. Additionally, the expression pattern of NAC2 (a transcription factor) and BGL2 in different tissues and under different stress conditions was analyzed relative to ACT and GAPDH and UBQ (ubiquitin) the least stably expressed gene. NAC2 and BGL2 both had highest expression in flowers and pods under ABA stress at 48h. This study provides useful reference genes for future gene expression studies in black locust.
