Floral Homeotic

The studies on floral homeotic mutants of the model plant species Arabidopsis thaliana (L.) Heynh. and Antirrhinum majus L. have clarified many important aspects of the genetic control of flower development. However, the details of this process can vary in species representing different lineages of flowering plants. The studies on floral homeotic mutants of nonmodel plant species may significantly improve the understanding of the mechanisms of morphological evolution of flowers. We report here the results of the genetic and morphological analysis of two floral homeotic mutants of common buckwheat ( Fagopyrum esculentum Moench.). The mutant, tepal-like bract (tlb), is characterized by the transformation of bracts into petaloid organs, whereas fagopyrum apetala (fap), has a carpelloid perianth. Both mutant phenotypes are caused by a single recessive nuclear mutation. The double mutant fap tlb combines the features of tlb and fap. Our results show that single gene mutations are sufficient to convert the buckwheat bract into a tepal and to confer carpel identity on first whorl organs. These results are consistent with the premise that variations on the ABC model can be used to explain a wide range of floral architectures.

Fagopyrum Esculentum Moench

Beekeeping is one of the promising enterprises for economically poor farmers in Nepal but beekeeping farmers lack flora calendar for pollination, bee foraging, and honey production. Therefore, a study was conducted visiting farmers’ fields every 15-20 days during 2012-2013 to monitor the common plant species visited by bees, which were considered as bee forage plants categorized as major, and minor sources of pollen and/or nectar.  Relevant information was also gathered through key informant interviews and group discussions. During the study period a total of 252 plant species were recorded and their floral calendar prepared. In the study area. The main species identified were: rice, Oryza sativa L.; maize, Zea mays L.; buckwheat, Fagopyrum esculentum Moench.; rapeseed, Brassica campestris L.; sesame, Sesamum   orientale L.; litchi, Litchi chinensis Sonner; and cucurbits (bottle gourd,  Lagenaria siceraria (Molina) Standl; sponge gourd, Luffa cylindrica  (L.) Roem.; bitter gourd, Momordica charantia L.), Leucas (gumpate), Leucas lanata Benth.; Butternut (chiuri),  Bassia butyracea Roxb.; Pogostemon (rudilo), Pogostemon glaber Benth.; guava, Pisum sativum L;  Sisoo, Dalbergia sissoo Roxb.; Throughwort (Banmara), Eupatorium sp.; silk tree (Padke), Albizia julibrissin Durazz ; Terminalia (Saj) Terminalia bellirica (Geartn.) Roxb. and Murraya (kadipatta) Murraya koenigii (L.) Spreng.  Species of Brassica, Pogestemon, Bassia, Citrus, and Artemisia, Pisum, Ipomoea and Eupatorium species were some of the important plants which bloomed during winter. And, Lagerstroemia sp., Impatiens sp, Sesamum indicum L., Zea mays L., Albizia sp. and many cucurbits bloomed during rainy season. Fagopyrum esculentum Moench, Brassica campestral L, Lagerstroemia indica L, Bombax ceiba L, Albizia julibrissin Durazz., Eugenia formosa Wall., Shorea robusta, Guartn. Upatorium grandulosum, Pogostemon glaber Benth. Terminalia alata Heyne ex.Roth, Murraya koenigii (L.) Spreng Sesamum orientale L. Dalbergia sissoo Roxb. were the major bee flora both rich in nectar and pollen.

Background: Fagopyrum esculentum Moench. is a herb consumed as food and has medicinal value. It is a rich source of bioactive nutrients which cure and prevent many ailments. Traditionally, it is used to treat hypertension, diabetes, constipation, cancer etc. Methods and Objective: Present work illustrates morphological, microscopic and physicochemical parameters of Fagopyrum esculentum seeds as per WHO guidelines, in vitro antioxidant activity; assessed by DPPH scavenging method, hydrogen peroxide scavenging assay and β-carotene linoleic acid bleaching method and study of lipid lowering potential of the ethyl acetate and ethanol extract of seeds on normal diet fed Wistar rats. Results: Morphological studies delineated the triangular shape, dark brown colour, 8 mm length and 6 mm width of the seed. The microscopic examination of the transverse section of seed depicted features like testa or pericarp (seed coat), the endosperm, embryo and sclerenchyma cells. Study of physiochemical parameters exhibited 0.3±0.02% of foreign matter and 1.44±0.51% crude fibre content. Total ash, acid insoluble ash and water soluble ash value were 6.7±1.7%, 1.9±0.23% and 3.9± 0.31% respectively. Alcohol soluble and water soluble extractive value came out to be 65.02± 3.21 mg/g and 12.7±1.24 mg/g respectively. Foaming index was less than 100, swelling index was found to be 0.5±0.01 ml/g. Loss on drying was 4.02±1.27%. Phytochemical screening of ethyl acetate and ethanol extract revealed the presence of alkaloids, carbohydrates, phenolic compounds, phytosterols and flavonoids. Trace amount of heavy metals (arsenic, cadmium, lead, mercury) were determined by atomic absorption spectrophotometer. Pesticide residue analysis confirmed the presence of nontoxic pesticides like dimethipin, hymexazol, phenothrin-2, methoprene, triadimenol, prohydrojasmon- 1, jasmolin ii, triademinol, jasmolin i, prohydrojasmone i, cyromazine in both the extracts by gc-ms spectrometer. The ethyl acetate and ethanol extract has shown significant in-vitro antioxidant activities demonstrated by the DPPH method (IC50 = 94.37±2.51 and 216.04±4.39 μg/ml respectively), hydrogen peroxide scavenging assay (IC50 = 83.72±3.72 and 193.47±5.05 µg/ml respectively) and β-carotene bleaching method (IC50 = 100.67±4.01 and 205.39±2.89 µg/ml respectively). Lipid lowering study performed on Wistar rats demonstrated a significant (p<0.001) decrease in serum Total Cholesterol (TC), Triglyceride (TG) and increase in High Density Lipoprotein (HDL) level as compared to normal group. Both the extracts have shown a non significant difference in the level of TG as compared to standard drug atorvastatin, depicting that the efficacy of extracts is at par with that of standard drug atorvastatin. Conclusion: Pharmacognostical study of the plant can be a very good tool for identification as well as authentication of a herb. Moreover, these parameters may be helpful in the development of monograph of the plant. Pharmacological activity confirmed Fagopyrum esculentum Moench. seed to be a good antioxidant and have lipid lowering potential.

Fagopyrum Esculentum Moench

Common buckwheat (Fagopyrum esculentum Moench) is a valuable source of proteins, B vitamins, manganese, tryptophan, phytochemicals with an antioxidant effect, and the natural flavonoid rutin. Due to its composition, buckwheat supports the human immune system, regulates blood cholesterol, and is suitable for patients with diabetes or celiac disease. The study aimed to compare the allocation of selected phenolic acids (neochlorogenic acid, chlorogenic acid, trans-caffeic acid, trans-p-coumaric acid, trans-sinapic acid, trans-ferulic acid) and flavonoids (rutin, vitexin, quercetin, kaempferol) in the leaves, flowers, and grain of buckwheat cultivars of different origin. The content of individual phenolics was determined by the HPLC-DAD method. The results confirmed the determining role of cultivar on the relative content of chlorogenic acid, trans-caffeic acid, trans-sinapic acid, vitexin, and kaempferol in buckwheat plants. A significantly negative correlation among concentrations of phenolic acids in different common buckwheat plant parts shows that there are different mechanisms of genetic influences on the concentration of phenolic substances in common buckwheat flowers, leaves, and grain. These differences should be taken into account when breeding buckwheat for a high concentration of selected phenolic substances.
