Recurrent water deficit causes epigenetic and hormonal changes in citrus plants

Water-deficit stress-induced anatomical changes in higher plants.

Water is vital for plant growth and development. Water-deficit stress, permanent or temporary, limits the growth and the distribution of natural vegetation and the performance of cultivated plants more than any other environmental factors do. Although research and practices aimed at improving water-stress resistance and water-use efficiency have been carried out for many years, the mechanism in...

Hormonal causes of recurrent pregnancy loss (RPL).

Endocrine disorders play a major role in approximately 8% to 12% of recurrent pregnancy loss (RPL). Indeed, the local hormonal milieu is crucial in both embryo attachment and early pregnancy. Endocrine abnormalities, including thyroid disorders, luteal phase defects, polycystic ovary syndrome, hyperprolactinaemia and diabetes have to be evaluated in any case of RPL. Moreover, elevated androgen ...

Cryopreservation Causes Genetic and Epigenetic Changes in Zebrafish Genital Ridges

Cryopreservation is an important tool routinely employed in Assisted Reproduction Technologies (ARTs) and germplasm banking. For several years, the assessment of global DNA fragmentation seemed to be enough to ensure the integrity of genetic material. However, cryopreservation can produce molecular alterations in key genes and transcripts undetectable by traditional assays, such modifications c...

effect of glomus mosseae and water deficit stress on growth and root antioxidant enzyme changes in citrus

a greenhouse experiment was performed in the framework of a completely randomized design and a factorial arrangement to evaluate the effect of arbuscular mycorrhizal fungi (amf) on growth and on root antioxidant enzyme changes of two citrus rootstocks (sour orange and rough lemon). the experimental factors were: mycorrhizal treatments at two levels (inoculation with glomus mosseae vs. control) ...
