Heat stress reduces grain yield and quality worldwide. Enhancing heat tolerance of crops at all developmental stages is one of the essential strategies required for sustaining agricultural production especially as frequency of temperature extremes escalates in response to climate change. Although heat tolerance mechanisms have been studied extensively in model plant species, little is known abo...

Loss-of-function mutations of SQUINT (SQN)-which encodes the Arabidopsis orthologue of cyclophilin 40 (CyP40)-cause the precocious expression of adult vegetative traits, an increase in carpel number, and produce abnormal spacing of flowers in the inflorescence. Here we show that the vegetative phenotype of sqn is attributable to the elevated expression of miR156-regulated members of the SPL fam...

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...

The reproductive success of sibling cocklebur plants (Compositae: Xunthium strumarium) was monitored after growth at different levels of availability of water and nutrient resources. Variation in reproductive success among individual plants was related to physiological, structural, and phenological characteristics. Reproductive success increased with increased availability of resources, but the...

One strategy to increase shallot productivity is use fertilizers and growth regulators. The aim of the study was determine response vegetative generative shallots local Eban cultivars through application gibberellins P in middle plains North Central Timor District. This used a factorial randomized block design (RBD). first factor (GA3), consisting three treatments, namely without GA3 (control),...

Frequent and intense defoliation of grasses has been associated with the evolution of “grazing morphotypes” that exhibit a variety of vegetative traits correlated with improved grazing resistance. While recovery from a seed bank is not considered an important grazing resistance mechanism, relatively little is actually known regarding seed (caryopsis) production in grazing morphotypes of caespit...

Information is given about the finding of Hieracium pilosella L. in Issyk River valley on northern slope Zailiysky Alatau ridge. The habitat species, composition plant community with its participation are described, data population density ratio generative and vegetative individuals provided. appearance this adventive species immediate vicinity Almaty last decade most likely due to increasing r...

1 Herbivore damage often induces the release of herbivore-induced plant volatiles (HIPVs) or the secretion of extrafloral nectar (EFN). The purpose of this study was to induce such proposed indirect defence responses in plants growing in their natural environment and to monitor the effects on vegetative and generative traits such as herbivory, plant growth and fruit set. 2 I tested whether matu...

background & aim: nowadays, the application of traditional medicine and herbal medicinal plants instead of chemical and synthetic drugs has captured the attention of the researchers. the purpose of this study was to investigate the antimicrobial effects of the aquatic, ethanolic and methanolic (80%) extracts of the aerial and root parts of stachys lavandulifolia vahl which were taken from t...
