Cotton (Gossypium hirsutum L.) plants were grown in sand culture on nutrient solution containing adequate or growth-limiting levels of P. When water was withheld from the pots, stomata of the most recently expanded leaf closed at leaf water potentials of approximately -16 and -12 bars in the normal and P-deficient plants, respectively. Pressure-volume curves showed that the stomata of P-deficie...

The focus of the review is on the specific aspects of Ni and Zn effects on growth morphology, Biochemical activity/responses, mineral nutrition and enzyme activity of plants. The quantity of Ni required for normal growth and development of plant is very low. Ni has been identified as a component of various enzymes in plants, various other biochemical, physiological and growth responses. The con...

Although it’s not very well known in the world of nutrition, chlorophyll couldn’t be more important in the world of biology and plants. All green plants contain at least one type of chlorophyll (chlorophyll a). Plants that evolved at a later point in history (“higher plants”) also contain a second type of chlorophyll (chlorophyll b). There are also forms of chlorophyll called chlorophyll c1, c2...

In the course of plant evolution, there is an obvious trend toward an increased complexity of plant bodies, as well as an increased sophistication of plant behavior and communication. Phenotypic plasticity of plants is based on the polar auxin transport machinery that is directly linked with plant sensory systems impinging on plant behavior and adaptive responses. Similar to the emergence and e...

Hydroponics is a way of farming that does not use soil, but only uses water contains nutrients. The growth hydroponic plants can be influenced by various factors, one which lack nutrition in plants. Therefore, this study aims to create system functions control nutrition, as well the availability sufficient reservoirs. This process NodeMCU esp8266 and processes sensor data then sends it firebase...

Since the use of antibiotics in animal feeds has been banned, researches on alternative natural products that modulate ruminal fermentation have been intensified. Natural compounds such as plant extracts have been considered to be replaced antibiotics as safe and sustainable alternatives. Plant extracts especially essential oils and saponins have strong antimicrobial, antiparasitic, antiprotozo...

Iron (Fe) and copper (Cu) homeostasis are tightly linked across biology. Understanding crosstalk between Fe and Cu nutrition could lead to strategies for improved growth on soils with low or excess metals, with implications for agriculture and phytoremediation. Here, we show that Cu and Fe nutrition interact to increase or decrease Fe and/or Cu accumulation in leaves and Fe uptake processes. Le...

Now is the time for the science of nutrition, with its application in food and nutrition policy, to be given a broader definition, additional dimensions and relevant principles, to meet the challenges and opportunities faced by humankind in the twenty-first century. As originally conceived and as now usually studied and practised, nutrition is principally a biological science. This classic biol...

Fungal pathogens derive nutrition from the plants they invade. Some fungi can subvert plant defence responses such as programmed cell death to provide nutrition for their growth and colonisation. Secondary metabolite toxins produced by fungi often play a role in triggering these responses. Knowledge of the biosynthesis of these toxins, and the availability of fungal genome sequences and gene di...

Lead is a nonessential element that has a negative effect on plant growth and development. Plant symbiosis with arbuscular mycorrhizal fungi (AMF) in soils contaminated with heavy metals can affect growth of plant, nutrition and tolerance against heavy metals. In this study, the effect arbuscular mycorrhizal fungi Glomus intraradices on the growth, photosynthetic pigments, protein content, prol...
