Dactylotrochus cervicornis (= Tridacophyllia cervicornisMoseley, 1881), which occurs in Indo-Pacific waters between 73 and 852m,was originally described as an astraeid butwas later transferred to theCaryophylliidae.Assumed to be solitary, this species has no stolons and only one elongated fossa, and is unique among azooxanthellate scleractinians in often displaying extremely long thecal extensi...

BEL1-like transcription factors are ubiquitous in plants and interact with KNOTTED1 types to regulate numerous developmental processes. In potato (Solanum tuberosum subsp. andigena), the BEL1-like transcription factor StBEL5 and its Knox protein partner regulate tuber formation by targeting genes that control growth. RNA detection methods and heterografting experiments demonstrated that StBEL5 ...

Imperata cylindrica Linn. Beauv (Poaceae), commonly known as Darbh in Hindi, is an important drug of “Trinpanchmool” and used extensively for the treatment of various ailments viz. urinary calculi, retention of urine, diabetes, cardiac disorder, gout, common cough and cold, inflammation, anemia, as aphrodisiac, etc. The present study was aimed to undertake pharmacognostical studies to fulfill t...

Pistia stratiotes is an aquatic macrophyte that grows in temporary-ponds in the southern Pantanal, Brazil. It reproduces both sexually and asexually and is usually observed forming dense mats on the water surface, a condition favored by the plant's vegetative reproduction coupled with an ability for rapid growth. In this study we examined the effect of densely crowded conditions on the producti...

BACKGROUND AND AIMS Because plants protect each other from wind, stand density affects both the light climate and the amount of mechanical stress experienced by plants. But the potential interactive effects of mechanical stress and canopy shading on plant growth have rarely been investigated and never in stoloniferous plants which, due to their creeping growth form, can be expected to respond d...

BELL1-like transcription factors interact with their protein partners from the KNOTTED1 family to bind to target genes and regulate numerous developmental and metabolic processes. In potato (Solanum tuberosum), the BELL1 transcription factor StBEL5 and its protein partner POTH1 regulate tuber formation by affecting hormone levels. Overexpression of StBEL5 in transgenic lines produces plants tha...

Caulerpa racemosa is a tropical green alga introduced into the Mediterranean probably as an immigrant from the Red Sea. This study evaluated the modifications caused by C. racemosa invasion on the structure of the benthic macroalgal community near Leghorn (northwestern Mediterranean). To achieve this objective, we studied invasion by C. racemosa of algal assemblages on 2 different substrata by ...

Clonal plants, which reproduce by means of stolons and rhizomes, are common in frequently flooded habitats. Resilience to disturbance is an important trait enabling plants to survive in such highly disturbed habitats. Resource storage is thought to enable clonal plants to resume growth after clonal fragmentation caused by disturbance. Here we investigated if submergence prior to disturbance red...

In the genus Gunnera , the species of subgenus Panke are unique in having large, triangular scales between the leaves on the rhizomes. The morphological significance of these scales has been extensively debated in the past. They have been interpreted as stipules, ligules, or cataphylls, with attempts made to identify homologous structures in representatives of the other subgenera. In the stolon...

The scientific research aims to establish the effect of modern insectofungicides Prestige and Respect on development potato rhizoctoniosis in agroecosystem crops region. authors evaluated effectiveness preparations under conditions production planting potatoes JSC “Sea Fields” during period from 2015 2020. Under farm conditions, seed tubers are heavily (on average 38.5%) infested with sclerotia...
