An L-type lectin receptor-like kinase promotes starch ...

Downregulation of this gene results in failed accumulation of starch in pollen, thus leading to male sterility (Mu et al., 2009). RA68 is a gene expressed preferentially in shoots and flowers with unknown function; RA68 knockdown plants show a reduction in pollen viability due to severely defective starch accumulation (Li et al., 2010).

Molybdenum | Linus Pauling Institute | Oregon State University

Disease Prevention Esophageal cancer. Linxian is a small region in northern China where the incidence of cancer of the esophagus and stomach is very high (10 times higher than the average in China and 100 times higher than the average in the US). The soil in this region is low in molybdenum and other mineral elements; therefore, dietary molybdenum intake is also low.

Soil, the biologically active, porous medium that has developed in the uppermost layer of Earth''s crust. It is one of the principal substrata of life on Earth, serving as a reservoir of water and nutrients, as a medium for the filtration and breakdown of wastes, and as a participant in the cycling of elements.

An L-type lectin receptor-like kinase promotes starch ...

Starch accumulation is key for the maturity of rice pollen grains; however, the regulatory mechanism underlying this process remains unknown. Here, we have isolated a male-sterile rice mutant, abnormal pollen 1 (ap1), which produces nonviable pollen grains with defective starch accumulation.Functional analysis revealed that AP1 encodes an active L-type lectin receptor-like kinase (L-LecRLK).

Heavy Metal Polluted Soils: Effect on Plants and ...

Soils polluted with heavy metals have become common across the globe due to increase in geologic and anthropogenic activities. Plants growing on these soils show a reduction in growth, performance, and yield. Bioremediation is an effective method of treating heavy metal polluted soils. It is a widely accepted method that is mostly carried out in situ</i>; hence it is suitable for the ...

anthracnose | Description, Symptoms, & Control | Britannica

Anthracnose causes the wilting, withering, and dying of tissues. It commonly infects the developing shoots and leaves. The causative fungi (usually Colletotrichum or Gloeosporium) characteristically produce spores in tiny, sunken, saucer-shaped fruiting bodies known as acervuli.Symptoms include sunken spots or lesions of various colours in leaves, stems, fruits, or flowers, and some infections ...

Mechanism of Salinity Tolerance in Plants: Physiological ...

Salinity is a major abiotic stress limiting growth and productivity of plants in many areas of the world due to increasing use of poor quality of water for irrigation and soil salinization. Plant adaptation or tolerance to salinity stress involves complex physiological traits, metabolic pathways, and molecular or gene networks. A comprehensive understanding on how plants respond to salinity ...

Aminolevulinic acid - Wikipedia

δ-Aminolevulinic acid (also dALA, δ-ALA, 5ALA or 5-aminolevulinic acid), an endogenous non-proteinogenic amino acid, is the first compound in the porphyrin synthesis pathway, the pathway that leads to heme in mammals, as well as chlorophyll in plants.. 5ALA is used in photodynamic detection and surgery of cancer.

Nicotine - Wikipedia

Nicotine is a chiral alkaloid that is naturally produced in the nightshade family of plants (most predominantly in tobacco and Duboisia hopwoodii) and is widely used recreationally as a stimulant and anxiolytic.As a pharmaceutical drug, it is used for smoking cessation to relieve withdrawal symptoms. Nicotine acts as a receptor agonist at most nicotinic acetylcholine receptors (nAChRs), except ...

Diseases | Free Full-Text | Anti-Angiogenic Therapy ...

Anti-angiogenics currently used in cancer therapy target angiogenesis by two major mechanisms: (i) neutralizing angiogenic factors or their receptors by using macromolecule anti-angiogenic drugs (e.g., therapeutic antibodies), and (ii) blocking intracellularly the activity of receptor tyrosine kinases with small molecule (Mr &lt; 1 kDa) inhibitors. Anti-angiogenics halt the growth and spread ...

How Plants Survive The Cold (Or Not) – How Plants Work

Jan 07, 2010· How Do Plants Cope With the Cold? To answer this question we have to consider plants at the cellular level. How do the cells of cold-tolerant plants survive sub-freezing temperatures, i.e., withstand dehydration and, more importantly at very low temperatures (below 0 o F or -18 o C), avoid the formation of ice crystals in the cell? 1.

Phosphorus Uptake by Plants: From Soil to Cell | Plant ...

P is an important plant macronutrient, making up about 0.2% of a plant''s dry weight. It is a component of key molecules such as nucleic acids, phospholipids, and ATP, and, consequently, plants cannot grow without a reliable supply of this nutrient. Pi is also involved in controlling key enzyme

Soil - Wikipedia

Soil formation, or pedogenesis, is the combined effect of physical, chemical, biological and anthropogenic processes working on soil parent material.Soil is said to be formed when organic matter has accumulated and colloids are washed downward, leaving deposits of clay, humus, iron oxide, carbonate, and gypsum, producing a distinct layer called the B horizon.

Effects of abiotic stress on plants: a systems biology ...

Nov 17, 2011· The natural environment for plants is composed of a complex set of abiotic stresses and biotic stresses. Plant responses to these stresses are equally complex. Systems biology approaches facilitate a multi-targeted approach by allowing one to identify regulatory hubs in complex networks. Systems biology takes the molecular parts (transcripts, proteins and metabolites) of an organism and ...

Bioaccumulation - Wikipedia

Bioaccumulation is the gradual accumulation of substances, such as pesticides or other chemicals, in an organism. Bioaccumulation occurs when an organism absorbs a substance at a rate faster than that at which the substance is lost or eliminated by catabolism and excretion.Thus, the longer the biological half-life of a toxic substance, the greater the risk of chronic poisoning, even if ...

Magnesium deficiency in plants: An urgent problem ...

Apr 01, 2016· Putrescine accumulation in cells is a universal response to stress in plants. Anthocyanins in red grape cell suspension culture are increased and their catabolism is decreased under Mg 2 + treatment [105], as is in several ornamental plants by spraying the foliage or by drenching pot plants with Mg 2 + solution [106], [107] .

Phytoextraction: The Use of Plants to Remove Heavy Metals ...

Jan 01, 2016· MTs synthesis in plants is initiated when it encounters heavy metals such as Cd, Hg, Zn, Pb, and silver, but the highest levels of MTs are released in the presence of Cd toxicity. PCs are involved in providing tolerance to heavy metals and allow efficient accumulation of these metals in plants organs. They are thiol peptides with γ-Glu-Cys ...

Effects of growth under different light spectra on the ...

Under such conditions, sugar accumulation can help plants to cope with HL damage (Ciereszko et al. 2001). Carbohydrate accumulation can induce the production of anthocyanin. Chalcone synthase as the key enzyme in anthocyanin biosynthesis can be activated by the signal from soluble carbohydrates (Koch 1996; Deng et al. 2014).

Silica in Plants: Biological, Biochemical and Chemical ...

Oct 06, 2007· Si accumulation has been found to a greater extent, but not exclusively, in monocotyledonous plants. Plants of the families Poaceae, Equisetaceae and Cyperaceae show high Si accumulation (>4 % Si), the Cucurbitales, Urticales and Commelinaceae show intermediate Si accumulation (2–4 % Si), while most other species demonstrate little accumulation.
