Abstract Petals and leaves share common evolutionary origins but have different phenotypic characteristics, such as the absence of stomata in petals most angiosperm species. Plant NAC transcription factor, NAP, is involved ABA responses regulates senescence-associated genes, especially those that affect stomatal movement. However, regulatory mechanisms significance NAP action senescing astomato...

today, most of the big cities or metropolises around the world have been encountering with the problem of informal habitation. the present study, thus, tries to focus on the role of endogenous development in such type of habitation process. for that matter, the paper takes into account architectural programming and urbanism as its theoretical framework because the endogenous development is rela...

BRs (brassinosteroids), an endogenous hormone in plants, regulate cellulose accumulation, cell elongation and plant growth. Propiconazole (PCZ) is effective inhibitor of BR biosynthesis. DCB (2,6-Dichlorobenzonitrile) can inhibit the synthesis affects chemical composition walls. Celery one important leafy vegetable Apiaceae family with rich dietary fiber (including cellulose). The petioles leng...

background heat shock protein 72 (hsp72) is responsible for maintaining critical cellular function during heat stress. hsp72 confers thermotolerance and may play a role in heat acclimation. animal research suggests a difference between sexes in hsp72 expression in response to exercise, however, human data is lacking. conclusion our findings suggest that men and women differ in their cellular st...

Abstract Background Strawberry ( Fragaria × ananassa Duch.) is an important fruit crop worldwide. It was particularly sensitive to drought stress because of their fibrous and shallow root systems. Mutant rty Arabidopsis thaliana ROOTY RTY ) results in increased endogenous auxin levels, more roots, shoot growth. still unclear whether the gene improves tolerance strawberry. Results isolated from ...

The transition from endogenous to exogenous feeding is critical during fish early life, where appropriate feed availability and timing of initiation influence survival. For European eel (Anguilla anguilla), establishing first culture at a pioneering state, successful production larvae has recently enabled experiments. In the present study, three diets potential benefits yolk-sac stage were expl...

Formation of a complete immunoglobulin heavy-chain transcription unit involves the ordered rearrangement of variable (V), diversity (D), and joining (J) region gene segments. In antibody-producing cells, this process is regulated such that only one of two antibody genes is expressed. Experiments with transgenic mice suggest that this mechanism, known as allelic exclusion, is mediated through th...

Cell cycle checkpoints appear to contribute to an increase in cell survival and a decrease in abnormal heritable genetic changes following exposure to DNA damaging agents. Though several radiation-sensitive yeast mutants have been identified, little is known about the genes that control these responses in mammalian cells. Recent studies from our laboratory have demonstrated a close correlation ...

Transcription from modified chloroplast genes has been studied in vitro, but only with the recently developed ability to stably introduce foreign DNA into Chlamydomonas reinhardtii chloroplast chromosomes in situ has it become possible to do so in vivo. Cloned chloroplast DNA sequences, into which had been inserted chimeric genes composed of the GUS coding sequence reporter under transcriptiona...
