Malania oleifera(Olacaceae)is a valued tree species,mostly because its seeds have high precious fatty acid content(particularly nervonic acid).However,seedling mortality rates are often high and regeneration of this tree has been problematic,which greatly hinders its utilization at a large scale.Cultivation difficulties of some tree species in the family Olacaceae have been attributed to their root hemiparasitic habit.Prompted by field observations and the taxonomic proximity of M.oleifera to root hemiparasites in Olacaceae,we hypothesized that tuberous structures observed on the roots of M.oleifera are parasitic organs known as haustoria.To test this hypothesis,we collected root samples from M.oleifera plants of various ages and growth conditions,investigated the morphological and anatomical features of tuberous structures and their connections to neighboring roots.Our analyses confirmed that M.oleifera are root hemiparasites.To the best of our knowledge,this is the first empirical report on root hemiparasitism in M.oleifera.Because life strategies of root hemiparasitic plants differ greatly from autotrophic plants,the root hemiparasitic habit needs to be taken into account for successful seedling regeneration of M.oleifera.This study establishes the foundation for investigations into a long-neglected but essential aspect in research of these highly valued tree species.

Camellia oleifera Abel.is an important economic tree species of southern China.In this study,we evaluated the mating system and genetic diversity of a series of cultivars of C.oleifera‘Ruan Zhi’.A total of 159 individuals from the progenies of four cultivars were tested by simple sequence repeat molecular markers.Results reveal that 11 pairs of primers showed polymorphism and their polymorphism information content value was greater than 0.73,suggesting that these primers could be used to identify the genetic diversity of open-pollinated populations.The average number of effective alleles(Ne=4.88)was significantly different from the average number of alleles(Na=12.18),and their distribution in the sample population was not uniform.The average observed heterozygosity(Ho=0.96)was greater than the average expected heterozygosity(He=0.79),and the population heterozygote was excessive.Shannon index was 1.84 and populations showed high genetic diversity.As regards to the mating system,the multilocus outcrossing rate was 0.996,and the single locus 0.866.These results indicate a high degree of outcrossing by C.oleifera‘Ruan Zhi’.We recommend selecting individuals for high genetic gain from the progenies of cultivars because of outcrossing characteristics and genetic diversity for application to germplasm conservation and promotion.

Camellia oil extracted from the seeds of Camellia oleifera Abel.is a popular and high-quality edible oil,but its yield is limited by seed setting,which is mainly caused by self-incompatibility(SI).One of the obvious biological features of SI plants is the inhibition of self-pollen tubes;however,the underlying mechanism of this inhibition in C.oleifera is poorly understood.In this study,we constructed a semi-in vivo pollen tube growth test(SIV-PGT)system that can screen for substances that inhibit self-pollen tubes without interference from the genetic background.Combined with multi-omics analysis,the results revealed the important role of galloylated catechins in self-pollen tube inhibition,and a possible molecular regulatory network mediated by UDP-glycosyltransferase(UGT)and serine carboxypeptidase-like(SCPL)was proposed.In summary,galloylation of catechins and high levels of galloylated catechins are specifically involved in pollen tube inhibition under self-pollination rather than cross-pollination,which provides a new understanding of SI in C.oleifera.These results will contribute to sexual reproduction research on C.oleifera and provide theoretical support for improving Camellia oil yield in production.

Objective: To evaluate the effect of Moringa oleifera leaf ethanol extract as an adjunct treatment on lead acetate induced hepatonephrotoxicity in rabbits. Methods: Thirty-six male New Zealand White rabbits were assigned into two main groups. The first group(14 rabbits) served as normal control. The second group(22 rabbits) was administered orally with lead acetate at a dose of 40 mg/kg/day, 5 days/week for 8 weeks. At the 4 th and the 8 th week of treatment, 6 animals(3 animals at each period) of the second group were sacrificed while the remaining animals(16 rabbits) were assigned randomly into 2 subgroups(8 rabbits each): treated and non-treated. The first subgroup was orally given 1 m L phosphate-buffered saline for further 4 weeks while the second subgroup was administered orally with Moringa oleifera leaf ethanol extract at a dose of 400 mg/kg/day for the same period. Blood samples were collected to determine hematological and serum biochemical indices. Tissue specimens were collected from the liver and kidney for evaluation of the oxidant/antioxidant markers and for histopathological examinations.Results: Lead acetate exposure decreased the mean body weight gain, hematocrit, hemoglobin, mean corpuscular volume, and lymphocytes count. Moreover, it markedly increased counts of monocytes and platelets, serum enzyme activity, levels of creatinine, total cholesterol, triglycerides, and low-density lipoprotein cholesterol. Malondialdehyde level was markedly increased while the reduced glutathione content was significantly decreased in liver tissue of lead intoxicated-rabbits. Histopathological alterations were also noticed in the liver and kidney of lead intoxicated rabbits. Moringa oleifera leaf ethanol extract significantly improved hematological and serum biochemical parameters and histopathological structure of the liver and kidney. Conclusions: Moringa oleifera leaf ethanol extract ameliorates hemato-biochemical and histopathological alterations caused by lead acetate and improves hepatic and renal function

Objective: To analyze the phytochemical constituents, and to explore potential protective effect of the methanol extract of Moringa oleifera(M. oleifera) seeds and Egyptian propolis, each alone or concurrently administered on acetic acid-induced ulcerative colitis in rats. Methods: Eight groups of 5 rats each were used: normal control group with distilled water, model group, two groups with M. oleifera seeds(100 and 200 mg/kg), two groups with propolis(50 and 100 mg/kg), one group with concurrent administration of both, and one group with prednisolone(reference drug). Macro-and microscopic picture, ulcer index and lesion scores, oxidative markers, inflammatory mediators, in vitro activity of the inflammatory enzymes and 1, 1-diphenyl-2-picrylhydrazyl free radicals scavenging activity were evaluated. The phytochemical constituents of both extracts were explored by GC-MS analysis. Results: Both treatments modulated the macro-and microscopic picture, decreased the ulcerative index, lesion score, oxidative markers and inflammatory mediators, and inhibited the COX-1 and COX-2 enzymes. Propolis appeared to be powerful free radicals scavenger. A powerful synergistic effect of both treatments in modulating the course of the disease was reported. GCMS analysis of methanol extract of M. oleifera seeds and propolis revealed the presence of 50 and 34 compounds, respectively. Conclusions: M. oleifera seeds and propolis methanol extracts have modulated the course of acetic acid-induced ulcerative colitis. Moreover, both treatments induce a good synergistic effect against the disease. Isolation of the active constituents is recommended.
