Homeostasis in shoot apical meristems: The balance between stem cells and differentiated cells

Esin OLUK,[DOI: 10.24214/jecet.A.10.2.15971.]

It is known that the shoot apical meristem (SAM) has a dual function in the form of maintaining the existence of an active stem cell population and producing new organs at the same time, and that it maintains these functions with the effect of a group of basic cells in the middle, called the organization centre (OC). A large number of genes and the proteins they encode work in the relevant process. In this study, it has been tried to compile information about some of these genes and their functioning pathways by scanning publications on the subject in recent years.

Leila M. A. Hamed, Gaafar K. Nogod, Hythem S.A. Saeed, and Abdelmonem M. Abdellah ,[DOI: 10.24214/jecet.A.10.2.17283.]

It is well-documented that blood lead concentration level is greatly affected biochemical parameters of lead exposures. In this study, blood lead level of a total of 120 participants who sniffing lead containing substances was measured to investigate its effect on blood biochemical parameters, e.g., calcium (mg/dl), total protein (mg/dl), albumin (mg/dl), total bilirubin (mg/dl), direct bilirubin (mg/dl), indirect bilirubin (mg/dl), AST (U/L), ALT (U/L), cholesterol and triglyceride. Result indicated that all of the studied biochemical parameters were increased slightly by the increase of blood lead concentration level. The significant increase was noticed in both calcium and total bilirubin levels. Therefore, long-term of sniffing lead-containing substances increases blood lead level and accordingly causes negative health effects.

H. Do?a GÜNGÖR and Esin OLUK,[DOI: 10.24214/jecet.A.10.2.18491.]

There may be a difference between individuals belonging to the same plant species or even subspecies or varieties in a population, in terms of the amount and varieties of secondary metabolites they produce. Such individuals, who are systematically in the same category and differ in their chemical properties, are called chemotypes. In this study, the factors that are effective in the formation of chemotypes in plants, the naming of the formed chemotypes, the main compounds that vary and the examples of chemotypes were tried to be examined.

Requirements for Germination and in vitro Culture of Scrophularia depauperata BOISS Seedlings: An Endemic Herbaceous of Turkey

Bu?ra BAHÇEC? and Esin OLUK,[DOI: 10.24214/jecet.A.10.2.19201.]

Seed germination is the critical stage for species survival. Environmental factors are involved as spatio-temporal indicators of favorable conditions during this process. The current study assessed the effects of light, temperature and growth media on the germination and seedling growth of Scrophularia depauperata  BOISS., a norrow endemic herb from western Turkey. The seeds of the species exhibited an obligate light requirement. Highest germination ratio (71.25 %) occurred at 25 °C, under 16/8 photoperiod and in water agar (A), at the end of 14 d. Full strength Murashige Skoog’s medium (F) redounded to 28 d seedling growth in the manner of root/shoot elongation ratio and seedling dry/fresh weight. 1mg/L IBA robusted  the roots of the in vitro grown plantlets. Acclimatization consisted of two steps: Well rooted and acclimated seedlings in sand:peat:perlite substrate in a misty growth chamber (i), then were transferred and survived with 62 % in common garden soil in the greenhouse (ii). These results are expected to provide infromation which could be used for the establishment of Scrophularia depauperata  Boiss. in its natural habitat.

Bu?ra BAHÇEC? Y Esin OLUK,[DOI: 10.24214/jecet.A.10.2.20210]

La germinación de las semillas es el factor crítico para la supervivencia de las especies y depende de diferentes factores ambientales. En este estudio se evaluaron los efectos de la luz, temperatura y del medio de crecimiento sobre la germinación y posterior desarrollo de plántulas de Scrophularia depauperata  BOISS., una planta endémica de la región Oeste de Turquía. Las semillas mostraron un requerimiento total de luz. Las tasas mayores de germinación (71.3%) ocurrieron a 25°C a en un fotoperiodo de 16 h en agar simple (medio A) después de 14 días. Plántulas mantenidas en medio con las sales completas de Murashige y Skoog (medio F) mostraron un buen crecimiento observado como el cociente de la elongación raíz/parte aérea y peso seco/peso seco total. La inclusión de 1 mg l-1 de ácido indolbutírico favoreció el desarrollo de la raíces de las plántulas crecidas in vitro. La aclimatización incluyo una primera etapa en una mezcla tripartita de arena, turba y perlita en una cámara húmeda que resultó en un 62% de sobrevivencia, seguida por el trasplante definitivo a condiciones de invernadero. Estos resultados proveerán información para programas de propagación de Scrophularia depauperata  BOISS.y su posterior establecimiento en condiciones de su hábitat natural.

Macroscopic and microscopic characterizations of the gonads of the Guinean amberjack, Seriola carpenteri (Mather, 1971) from the artisanal maritime fishery in the Exclusive Economic Zone (EEZ) of Côte d'Ivoire.

Laizih Yves-Armand ATTEMENE, Vincent KADJO, Jean Noel YAPI, Mélécony Célestin BLE and Kouakou YAO,[DOI: 10.24214/jecet.A.10.2.21120.]

Characterization of the gonads of the Guinean amberjack, Seriola carpenteri (Mather, 1971) was undertaken based on macroscopic and microscopic observations of the gonads. The specimens come from the Ivorian Economic Exclusive Zone (EEZ), in the Gulf of Guinea. For example, a sample of 360 specimens of Seriola carpenteri (Mather, 1971) was sampled for 30 individuals per month from August 2017 to July 2018. Thus, each month the specimens of Seriola carpenteri sampled, are transported to the laboratory of pathological anatomy (AnaPath) for a histological study of the gonad in order to identify males and females. For each individual, the macroscopic aspect of the gonad was described. Then, a fragment of gonad in each individual was subjected to microscopic study. Macroscopic and microscopic characterization of female and male gonads highlighted six macroscopic and six microscopic stages. The oogenesis is continuous which translates that the ovaries of Seriola carpenteri are part of the synchronous type group.

The morpho-biometric characterization of goats was carried out in the town of Kindu. The animal population consisted of 121 goats including 97 females and 24 males aged between one and five years. The study focused on qualitative characteristics (coat color, presence (horn shape) or absence of horns, ear shape and body shape); on the quantitative characteristics (live weight (PV), length of the head (LT), length of the horns (LCorn), length of the ears (LO), scapulo-ischial length (LSI), length of the pelvis (LB), chest (TP), depth of the chest (PP), height at the withers (HG) and height at the sacrum (HS)) and on the biometric (or zootechnical) indices (body index or ratio (IB), the calculated weight ( PV), relative chest depth (PT) and body ratio (CR)). All the quantitative characteristics studied are positively and strongly correlated with each other. There are significant variations between weight, age and sex, but when it comes to breeding areas, they show no significant difference (p <0.1).Phenotypic diversity was observed within the goat population: Bucks are lighter (20.65 ± 4.64 kg) compared to females (28.10 ± 6.33 kg); they have characteristics similar to Djallonké goats while the females are much more like the Senegalese Sahel goat than the Fouta-Djalon dwarf goat. The average measurements were: PV = 26.62 ± 6.72 kg, LT = 15.53 ± 1.14cm, LCorn = 12.173 ± 3.16cm, LO = 12.69 ± 0.89cm, LSI = 57.545 ± 4.38cm, LB = 18.650 ± 1.56cm, XS = 69.793 ± 6.09cm, PP = 25.177 ± 2.30cm, HG = 51.751 ± 2.99cm and HS = 54.170 ± 2.92cm. Observations relating to zoo technical indices have shown that Kindu goats are mainly short-lined of the rectangular type, small in size (heliometric), close to the ground, with a rectilinear dorsal line, diverse coat color, horn tilted backwards (ibex ) and erect ears.

Brakus YUMA BRAHIMU, Défi AMURI ASSANI, Lingot BULEDI AMURI, Freddy OKITAYELA ONAWOMA,[DOI: 10.24214/jecet.A.10.2.26073.]

La caractérisation morpho biométrique des caprins a été réalisée dans la ville de Kindu. La population animale était constituée de 121 caprins dont 97 femelles et 24 mâles âgés de un à cinq ans. L’étude a porté  sur les caractères qualitatifs  (couleur de la robe, présence (forme de corne) ou absence des cornes, forme des oreilles et forme du corps) ; sur  les  caractères quantitatifs (poids vif (PV), longueur de la tête (LT), longueur des cornes (LCorn), longueur des oreilles (LO), longueur scapulo-ischiale (LSI), longueur du bassin (LB), tour de la poitrine (TP), profondeur de la poitrine (PP), hauteur au garrot (HG) et hauteur au sacrum (HS))  et sur les indices biométriques (ou zootechniques) ( indice ou rapport corporel (IB), le poids calculé (PV), profondeur thoracique relative (PT) et ratio corporel(RC)). Tous les caractères quantitatifs étudiés sont corrélés positivement et fortement entre eux. Il y a des variations significatives entre le poids, l’âge et le sexe mais quant aux zones d’élevage, ils ne présentent aucune différence significative (p<0,1).Une diversité phénotypique a été observée au sein de la population caprine : Les boucs sont moins lourds (20,65 ± 4,64 kg) par rapport aux femelles (28,10 ± 6,33 kg) ; ils présentent des caractéristiques proches aux boucs Djallonké tandis que les femelles s’apparentent beaucoup plus à la chèvre du Sahel Sénégalaise qu’à la chèvre naine de Fouta-Djalon. Les mensurations moyennes ont été : PV=26,62 ± 6,72 kg, LT=15,53 ± 1,14cm, LCorn=12,173±3,16 cm, LO=12,69±0,89cm, LSI=57,545±4,38cm, LB=18,650±1,56cm, TP=69,793±6,09cm, PP=25,177±2,30cm, HG=51,751±2,99cm et HS=54,170±2,92cm. Les observations relatives aux  indices zootechniques  ont montré que les caprins de Kindu sont majoritairement brévilignes du type rectangulaire, de petit format (héliométrique), près de terre, à ligne dorsale rectiligne, couleur de la robe diversifiée, corne inclinée vers l’arrière (ibex) et à oreilles dressées.

Uptake of Cd, Cr, Cu, Ni and Pb by castor oil plant (Ricinus communis L., Euphorbiaceae) growing wildly near waste dump site and assessment of phytoextraction capability for heavy metals">

Alok Awasthi ,[DOI: 10.24214/jecet.A.10.2.27484.]

Several plants have unique characteristic to selectively bio-concentrate heavy metals from contaminated soil into the roots and translocating to their shoots. Present study was carried out to evaluate the metal uptake potential of Castor oil plant, Ricinus communis L, Eurphobaceae, abundantly growing near waste dump site, for Cd, Cr, Cu, Ni and Pb. The bio-concentrated levels of studied metals in the samples of soil and plant parts were determined. The bio-concentration factors (BCF), translocation factors (TF) and bio-accumulation coefficients (BAC) for studied metals were computed, to assess the phytoremediation potential of the Castor oil plant for studied heavy metals.  The levels of heavy metals observed in soil, root and shoots of castor oil plant samples were: Pb (18.28 ±0.52) > Cr (14.46± 0.41) > Ni (7.54± 0.28) > Cu (6.88± 0.23) > Cd (2.86± 0.11) and Pb (18.64± 0.45) > Cr (15.92±0.36) > Ni (10.57±0.31) >Cu (9.14± 0.27) > Cd (3.84± 0.13) and Pb (19.76±0.49) > Cr (17.83±0.41)>Ni (13.95 ±0.29)>Cu (11.52±0.33) > Cd (5.42±0.16 mg/Kg, dw), respectively.  The computed values of soil to roots bio-concentration factors, BCFRoot for studied metals were: Cd (1.34) > Cu (1.33) >Ni (1.11) > Cr (1.10)>Pb (1.02). The order of various root to shoot translocation factors, TFShoot for these metals in Ricinus communis L. was: Cd (1.41) > Ni (1.32) > Cu (1.26) > Cr (1.12) > Pb (1.06) and the order of soil to shoot bio-accumulation coefficients, BACShoot was: Cd (1.89) > Ni (1.85)> Cu (1.67) > Cr (1.23) >Pb (1.08), respectively.  The higher values of BCF, TF and BAC all being >1 for studied metals suggests that the Ricinus communis L. has a good potential for phytoextraction (phytoremediation) of studied heavy metals from contaminated soil.
