At 3dpi the infected sheaths demonstrated distorted cellular anatomy while no alteration was detected at 1dpi. I was in love.

    For microtome sectioning, the infected and control rice sheaths were immersed in FAA fixative 3. Further, R. Also different strains demonstrate hyper variability in terms of its morphological and pathological attributes. We observed that initially R. The pathogenesis also marked an increase in carbohydrate metabolism in the infected tissues Table S3. In the xanthophyll cycle, violaxanthin is epoxidized and reduced to zeaxanthin during the day under high PPFD and stresses, consuming part of the excess electrons in the photosystem, and at night, with a lower metabolism, zeaxanthin is gradually de-epoxidized to violaxanthin, thus reducing the photoinhibitory effect Takahashi and Badger, Figure 1: Distorted cellular anatomy of R.

    S of rice sheaths were studied through histological staining. Notably, neither toluidine blue nor calcofluor white staining detected any alteration in infected PB1 sheaths at 1 dpi. It is important to quantify and understand the consequences of elevated temperature and carbon dioxide CO 2 on reproductive processes and yield to develop suitable agronomic or genetic management for future climates. Red kidney bean cv. There was no beneficial interaction of CO 2 and temperature, and CO 2 enrichment did not offset the negative effects of high temperatures on reproductive processes and yield.

    Life Cycles and Stages of the Bean Plant

    Symbiotic and kleptoplastic organisms excluded:. The biochemical capacity to use water as the source for electrons in photosynthesis evolved once, in a common ancestor of extant cyanobacteria formerly called blue-green algae. The geological record indicates that this transforming event took place early in Earth's history, at least — million years ago Ma , and, it is speculated, much earlier.

    How does Sunlight effect the growth of a Bean Seed?

    A clear paleontological window on cyanobacterial evolution opened about Ma, revealing an already-diverse biota of Cyanobacteria. Cyanobacteria remained the principal primary producers of oxygen throughout the Proterozoic Eon — Ma , in part because the redox structure of the oceans favored photoautotrophs capable of nitrogen fixation. Cyanobacteria remain critical to marine ecosystems as primary producers of oxygen in oceanic gyres, as agents of biological nitrogen fixation, and, in modified form, as the plastids of marine algae. Although some of the steps in photosynthesis are still not completely understood, the overall photosynthetic equation has been known since the 19th century.

    Jan van Helmont began the research of the process in the midth century when he carefully measured the mass of the soil used by a plant and the mass of the plant as it grew. After noticing that the soil mass changed very little, he hypothesized that the mass of the growing plant must come from the water, the only substance he added to the potted plant. His hypothesis was partially accurate — much of the gained mass also comes from carbon dioxide as well as water.

    However, this was a signaling point to the idea that the bulk of a plant's biomass comes from the inputs of photosynthesis, not the soil itself. Joseph Priestley , a chemist and minister, discovered that, when he isolated a volume of air under an inverted jar, and burned a candle in it which gave off CO 2 , the candle would burn out very quickly, much before it ran out of wax. He further discovered that a mouse could similarly "injure" air.

    He then showed that the air that had been "injured" by the candle and the mouse could be restored by a plant. In , Jan Ingenhousz , repeated Priestley's experiments. He discovered that it was the influence of sunlight on the plant that could cause it to revive a mouse in a matter of hours.

    In , Jean Senebier , a Swiss pastor, botanist, and naturalist, demonstrated that green plants consume carbon dioxide and release oxygen under the influence of light. Thus, the basic reaction by which photosynthesis is used to produce food such as glucose was outlined. Cornelis Van Niel made key discoveries explaining the chemistry of photosynthesis.

    By studying purple sulfur bacteria and green bacteria he was the first to demonstrate that photosynthesis is a light-dependent redox reaction, in which hydrogen reduces donates its — electron to carbon dioxide.

    Robert Emerson discovered two light reactions by testing plant productivity using different wavelengths of light. With the red alone, the light reactions were suppressed. When blue and red were combined, the output was much more substantial. PSI contains only chlorophyll "a", PSII contains primarily chlorophyll "a" with most of the available chlorophyll "b", among other pigment.

    These include phycobilins, which are the red and blue pigments of red and blue algae respectively, and fucoxanthol for brown algae and diatoms. Robert Hill thought that a complex of reactions consisting of an intermediate to cytochrome b 6 now a plastoquinone , another is from cytochrome f to a step in the carbohydrate-generating mechanisms. These are linked by plastoquinone, which does require energy to reduce cytochrome f for it is a sufficient reductant.

    Further experiments to prove that the oxygen developed during the photosynthesis of green plants came from water, were performed by Hill in and He showed that isolated chloroplasts give off oxygen in the presence of unnatural reducing agents like iron oxalate , ferricyanide or benzoquinone after exposure to light.

    The Hill reaction [72] is as follows:. Therefore, in light, the electron acceptor is reduced and oxygen is evolved. Samuel Ruben and Martin Kamen used radioactive isotopes to determine that the oxygen liberated in photosynthesis came from the water. Melvin Calvin and Andrew Benson , along with James Bassham , elucidated the path of carbon assimilation the photosynthetic carbon reduction cycle in plants.

    The carbon reduction cycle is known as the Calvin cycle , which ignores the contribution of Bassham and Benson. Nobel Prize -winning scientist Rudolph A. Marcus was able to discover the function and significance of the electron transport chain.

    Otto Heinrich Warburg and Dean Burk discovered the I-quantum photosynthesis reaction that splits the CO 2 , activated by the respiration. In , first experimental evidence for the existence of photophosphorylation in vivo was presented by Otto Kandler using intact Chlorella cells and interpreting his findings as light-dependent ATP formation. Arnon et al. Louis N. Duysens and Jan Amesz discovered that chlorophyll a will absorb one light, oxidize cytochrome f, chlorophyll a and other pigments will absorb another light, but will reduce this same oxidized cytochrome, stating the two light reactions are in series.

    In , Charles Reid Barnes proposed two terms, photosyntax and photosynthesis , for the biological process of synthesis of complex carbon compounds out of carbonic acid, in the presence of chlorophyll, under the influence of light. Over time, the term photosynthesis came into common usage as the term of choice. Later discovery of anoxygenic photosynthetic bacteria and photophosphorylation necessitated redefinition of the term. After WWII at late at the University of California, Berkeley , the details of photosynthetic carbon metabolism were sorted out by the chemists Melvin Calvin , Andrew Benson, James Bassham and a score of students and researchers utilizing the carbon isotope and paper chromatography techniques.

    For that original and ground-breaking work, a Nobel Prize in Chemistry was awarded to Melvin Calvin in At the University of Arizona, detailed gas exchange research on more than 15 species of monocot and dicot uncovered for the first time that differences in leaf anatomy are crucial factors in differentiating photosynthetic capacities among species. This type of anatomy was termed Kranz anatomy in the 19th century by the botanist Gottlieb Haberlandt while studying leaf anatomy of sugarcane.

    There are three main factors affecting photosynthesis [ clarification needed ] and several corollary factors. The three main are: [ citation needed ]. Total photosynthesis is limited by a range of environmental factors. These include the amount of light available, the amount of leaf area a plant has to capture light shading by other plants is a major limitation of photosynthesis , rate at which carbon dioxide can be supplied to the chloroplasts to support photosynthesis, the availability of water, and the availability of suitable temperatures for carrying out photosynthesis.

    The process of photosynthesis provides the main input of free energy into the biosphere, and is one of four main ways in which radiation is important for plant life. In the early 20th century, Frederick Blackman and Gabrielle Matthaei investigated the effects of light intensity irradiance and temperature on the rate of carbon assimilation. These two experiments illustrate several important points: First, it is known that, in general, photochemical reactions are not affected by temperature. However, these experiments clearly show that temperature affects the rate of carbon assimilation, so there must be two sets of reactions in the full process of carbon assimilation.

    These are the light-dependent 'photochemical' temperature-independent stage, and the light-independent, temperature-dependent stage. Second, Blackman's experiments illustrate the concept of limiting factors. Another limiting factor is the wavelength of light. Cyanobacteria, which reside several meters underwater, cannot receive the correct wavelengths required to cause photoinduced charge separation in conventional photosynthetic pigments. To combat this problem, a series of proteins with different pigments surround the reaction center. This unit is called a phycobilisome.

    As carbon dioxide concentrations rise, the rate at which sugars are made by the light-independent reactions increases until limited by other factors. RuBisCO , the enzyme that captures carbon dioxide in the light-independent reactions, has a binding affinity for both carbon dioxide and oxygen.
