since alkaline substances can rapidly penetrate into the cornea and subsequently damage limbal stem cells, another source of stem cells may be necessary to reconstruct the ocular surface. omentum has some such characteristics like ability to regenerate tissue as well as anti-inflammatory capacity. presence of adult stem cells and pluripotent embryonic cell markers make it suitable in wound heal...
Drought is a major abiotic factor adversely affecting wheat productivity. Water deficit reduces significantly photosynthesis and hence the remobilization of stored assimilate reserves from stem becomes important sources for grain filling. We assessed ability different internodes leaf sheaths to deposit remobilize reserve assimilates as well their role in yield formation 6 winter varieties under...
Background and Objective: Differentiation of mesenchymal stem cells into neurons has great potential in the therapy of damaged nerve tissue. Neural tissue engineering offers tremendous promise to combat the effects of disease, aging and injury in the nervous system. The aim of this study was to investigate the differentiation of adipose derived stem cells to neuron like cells on aligned nanofib...
To estimate potential impact of climate change on wheat fusarium ear blight, simulated weather for the A1B climate change scenario was imported into a model for estimating fusarium ear blight in central China. In this work, a logistic weather-based regression model for estimating incidence of wheat fusarium ear blight in central China was developed, using up to 10 years (2001-2010) of disease, ...
A recombinant inbred durum wheat population was grown under three contrasting regimes: long days following vernalization (LDV), long days without vernalization (LD), and short days following vernalization (SDV). The length of several pre-anthesis stages and the number of leaves and the phyllochron were measured. Different groups of genes were involved in determining the phenology in the three t...
Understanding the impact of the warming trend on phenological stages and phases of cotton (Gossypium hirsutum L.) in central and lower Punjab, Pakistan, may assist in optimizing crop management practices to enhance production. This study determined the influence of the thermal trend on cotton phenology from 1980-2015 in 15 selected locations. The results demonstrated that observed phenological ...
Plant vasculatures are complex tissues consisting of (pro)cambium, phloem, and xylem. The (pro)cambium serves as vascular stem cells that produce all vascular cells. The Arabidopsis ERECTA (ER) receptor kinase is known to regulate the architecture of inflorescence stems. It was recently reported that the er mutation enhances a vascular phenotype induced by a mutation of TDR/PXY, which plays a s...
Stem elongation in peas (Pisum sativum L.) is under partial control by gibberellins, yet the mechanism of such control is uncertain. In this study, we examined the cellular and physical properties that govern stem elongation, to determine how gibberellins influence pea stem growth. Stem elongation of etiolated seedlings was retarded with uniconozol, a gibberellin synthesis inhibitor, and the ...
BACKGROUND AND AIMS There is good evidence for deciduous trees that competition for carbohydrates from shoot growth accentuates early fruit abscission and reduces yield but the effect for evergreen trees is not well defined. Here, whole-tree tip-pruning at anthesis is used to examine the effect of post-pruning shoot development on fruit abscission in the evergreen subtropical tree macadamia (Ma...
