How does the autophagic pathway regulate low-nitrogen tolerance in tomato?
Nitrogen (N) deficiency first affects the N uptake and assimilation systems of plants. Nitrate, the main source of plant N, is absorbed and transported by nitrate transporters. Nitrate can be metabolized directly in the roots after absorption and sto.....»»

Salt stress promotes early flowering, inhibits floral organ development by disturbing cell cycle in tomatoes
A research team investigated the impact of salt stress on tomato (Solanum lycopersicum) floral transition, revealing that salt stress significantly reduced plant biomass and caused early flowering and smaller flowers. This study underscores the impor.....»»
"Kink state" control may provide pathway to quantum electronics
The key to developing quantum electronics may have a few kinks. According to a team led by researchers at Penn State, that's not a bad thing when it comes to the precise control needed to fabricate and operate such devices, including advanced sensors.....»»
Net effects of man-made nitrogen attenuate global warming, researchers find
Nitrogen fertilizers and nitrogen oxides from fossil fuels are known for their environmental damage: they pollute the air and drinking water, lead to over-fertilization of water and land ecosystems, reduce biodiversity and damage the ozone layer......»»
Next generation biosensor reveals gibberellin"s critical role in legume nitrogen-fixation
Researchers at the University of Cambridge have demonstrated that the plant hormone gibberellin (GA) is essential for the formation and maturation of nitrogen-fixing root nodules in legumes and can also increase nodule size. They identified the speci.....»»
Critically endangered Guam tree contributes to global leaf research
The intricate leaf design of Guam's Serianthes nelsonii tree was used as a model to contribute to the global goal of understanding how a plant leaf functions, and the results were published in the March issue of the journal Nitrogen......»»
Rhythmic gene expression in plants is crucial for symbiosis with nutrient-providing bacteria, study finds
Legumes thrive in low-nitrogen environments by partnering with rhizobia, soil bacteria that convert atmospheric nitrogen into ammonium, a usable form for the plants. These beneficial bacteria are housed in root nodules formed on legume roots......»»
Groundcherry gets genetic upgrades: Turning a garden curiosity into an agricultural powerhouse
Imagine a small fruit that tastes like a cross between a tomato and a pineapple, wrapped in its own natural paper lantern. That's the groundcherry (Physalis grisea)—a little-known relative of tomatoes that's been quietly growing in gardens and smal.....»»
Bubbling with benefits: Hydrogen nanobubbles boost tomato antioxidants
Tomatoes are a key source of antioxidants, crucial for human health as they help combat oxidative stress. Traditional irrigation methods often fail to significantly enhance these beneficial compounds in crops. Hydrogen, known for its unique antioxida.....»»
From roots to leaves: The nitrogen connection to photosynthetic efficiency
Photosynthesis efficiency in plants is influenced by the type of nitrogen absorbed. Ammonium (NH4+) and nitrate (NO3-) are the primary nitrogen sources, each affecting plant physiology differently. Variations in leaf anatomy, such as cell wall thickn.....»»
