ABSTRACT- To investigate the effect of draught stress on water relations, stomatal density, chlorophyll content and yield of rapeseed, an experiment was done with four levels of drought stress including L1 (Field Capacity, FC), L2 (70% Available Water Content, AWC), L3 (50% AWC), and L4 (30% AWC), within three growth stages- including stem elongation (T1), onset of flowering (T2) and silique fo...

linguatula serrata is a zoonotic parasite with global expansion, particularly in tropical and subtropical areas. the aim of this study was to evaluate the pathological lesions caused by l. serrata in mesenteric lymph nodes (mln) of water buffalo. to study the pathological lesions of nymphal stage in water buffaloes, enlarged and swollen mln were collected and examined. grossly, the mln were swo...

Msb1 is not essential for growth in the budding yeast Saccharomyces cerevisiae since msb1Δ cells do not display obvious phenotypes. Genetic studies suggest that Msb1 positively regulates Cdc42 function during bud development, since high-copy MSB1 suppressed the growth defect of temperature-sensitive cdc24 and cdc42 mutants at restrictive temperature, while deletion of MSB1 showed synthetic leth...

In the developing chick leg bud, massive programmed cell death occurs in the interdigital region. Previously, we reported the inhibition of cell death by separation of the interdigital region from neighboring digit cartilage. In this study, we examined the relationship between cell death and cartilaginous tissue in vitro. First, cell fate was observed with DiI that was used to examine cell move...

BACKGROUND Retinoic acid (RA) is present in the chick limb bud, and excess RA induces limb duplications. Here, we have investigated the role of endogenous RA during chick limb development by preventing the synthesis of RA and testing the effect on various genes expressed during limb initiation and outgrowth. RESULTS We demonstrate that the stage 20/21 limb bud synthesizes didehydroretinoic ac...

We searched for bioactive substances involved in flower bud formation of Arabidopsis thaliana. some significantly decreasing HPLC peaks were detected in the extract of flower buds-forming A. thaliana compared with that of the non-flower bud-forming stage. Compound 1, which corresponded to the most decreased HPLC peak, was isolated from aerial parts of A. thaliana. From NmR and ms data, compound...

Peach blossoms were harvested and classified into six developmental stages: (I) bud emerging stage; (II) middle bud stage; (III) large bud stage; (IV) initial-flowering stage; (V) full-flowering stage; and (VI) end-flowering stage. The contents of total phenolics, flavanoids, individual phenolic compounds as well as antioxidant and tyrosinase inhibitory activity of peach blossoms at different d...

Specification and determination (commitment) of positional identities precedes overt pattern formation during development. In the limb bud, it is clear that the anteroposterior axis is specified at a very early stage and is prepatterned by the mutually antagonistic interaction between Gli3 and Hand2. There is also evidence that the proximodistal axis is specified early and determined progressiv...

The outgrowth of the vertebrate tail is thought to involve the proliferation of regionalised stem/progenitor cell populations formed during gastrulation. To follow these populations over extended periods, we used cells from GFP-positive transgenic chick embryos as a source for donor tissue in grafting experiments. We determined that resident progenitor cell populations are localised in the chic...

This paper’s aim was to investigate the influence of variety and climatic year on vegetation phenophases in blueberries grown southwest Romania, Banat region. study carried out during growing season 2020–2022 a blueberry plantation, for ‘Duke’, ‘Hannah’s Choice’ ‘Elliott’ varieties. In study, phenological traits were recorded using BBCH scale observation phenotypic data as Julian days. Thus, it...
