Over the last decade low (< 130 mg kg -1) soil test potassium (K) levels and increased crop K deficiency have become a major concern in the clay-pan soils of southeast Kansas. The use of more intense crop rotations and the increased production of high K extracting crops (e.g. soybeans (Glycine max L.)) has significantly increased K removal from these soils. In addition, the traditional use of the nutrient sufficiency-based fertilizer recommendations has resulted in K application rates being substantially lower than removal rates. Because of these practices, many soils that had naturally elevated K availability 25 years ago have declined in K content. More troubling is the extreme yearly variation of soil test exchangeable K levels reported in the region, which has many producers and consultants concerned about proper K management. This study was initiated to examine the extent of K soil test variation and to determine if the variability is impacting plant K availability by analyzing soybean leaf K content and crop yield. A major objective of our research is to identify the mechanism(s) driving these changes in soil test K levels and K availability to crops during the growing season. The long-term goal is to be able to design a soil sampling system and develop alternative K fertilizer recommendation strategies that could alleviate K deficiency impacts on crop yield. Evaluation of different K fertilizer application practices including rate of application and broadcast or surface band methods of application were studied as tools to correct soybean K deficiency. The direct and residual impacts of K fertilization and placement were also evaluated on corn (Zea mays L.) grown in the rotation with the soybeans. Results observed from this research showed that monthly soil samples taken during three crop years at multiple locations have ammonium acetate exchangeable K levels that indeed change dramatically. The data we collected together with data accumulated by farmers and crop consultants showed significant fluctuation in exchangeable K levels of up to 50% on a yearly and even on a monthly basis. Levels seem to demonstrate seasonal changes: higher in the spring months and then decline in the summer and fall. Potassium soil test levels also appear to follow a similar trend as monthly precipitation and soil moisture status. During wet months soil levels tend to increase and then decline during drier months, however, this is not a perfect relationship and other factors are likely to be involved in regulating soil test K levels. No clear effect of K fertilization or method of placement on soybean or corn yields was observed during the study. However, soybean leaf samples revealed that on very low (< 90 mg kg -1) soil test sites surface band applied fertilizer increased leaf K concentrations compared to broadcasted applications. Furthermore, the corn study revealed no distinct difference between using a split annual or biannual fertilizer application system. Maintaining soil test K levels above 130 mg kg -1 using a spring soil test appears to be a successful strategy for avoiding K deficiency. Traditionally most soil sampling occurs in late summer or fall when soil conditions are dry. Our data has demonstrated that during this period one should expect to encounter low soil test results that may not be true indicators of soil K levels during the spring planting months. With that said, spring soil sampling can be difficult to do in a timely fashion due to weather, as well as potential labor restrictions. Another critical point is to not switch back and forth between spring and fall sampling dates. Staying consistent with your sample timing will minimize the seasonal variability that is frequently experienced. Additionally, adopting a build and maintain fertilizer recommendation philosophy rather than a nutrient sufficiency-based recommendation approach is a better nutrient budgeting method to avoid having removal rates exceeding nutrient additions. The best K management proposal would be to consider using a build and maintain approach in combination with basing fertilizer rates on spring soil test K levels.

Full textPotassium deficiency is a common phenomenon in cotton parcels. This problem is quite important in sub-Saharan Africa, where soils are poor and cropping systems are very low intensive. The main effects of potassium deficiency referenced in scientific literature are: (a) a reduction in leaf area, (b) a decrease in nutrient assimilation, and (c) a modification of nutrient repartition amongst compartments (i.e. stems roots, fruits, and leaves). Even though knowledge at the cellular level on the role of potassium is wide, ironically, only but a few models integrate results at the plant or stand levels. The reason comes from the multiplicity of mechanisms used and the complexity of integrating them throughout the plant or stand. The objective of our work is to characterize the effects of K-deficiency on the growth and development of cotton plants by including sufficient intermediate explanatory variables to provide a comparable scheme with the concepts used in growth models for this plant. This objective implies that our research focuses on different scales (i.e. stand, plant, organ, cell) and on physiological variables used in current models such as photosynthesis or water status. Our research had also led us to measure other variables not included in current models, to refine our understanding of the mechanisms of how deficient plants grows (i.e. sugar rates, carboxylation speed, stomata opening…). To meet these objectives, two complementary types of experiments were conducted: (i) field trials were performed in Benin on two different sites, Aplahoué in 2004 and Savalou in 2005, with strict rainfall conditions to compare different levels of potassium-fertilization and describe the effects of K-deficiency at the stand level. (ii) and a greenhouse hydroponic experiment was done in Bordeaux, France in 2006 to analyze the processes used throughout the plant and the organ. The field and the greenhouse tests had different levels of potassium fertilisation (2 to 3 levels in the field, 4 in the greenhouse) and gave us wide ranges of potassium contents in leaves. The minimum value of the leaf K content for the deficient plants were around 8 to 10 mg kg-1, which contrasts with the maximum values measured that were around 30 mg g-1. Potassium levels for the most deficient plants were around 8 to 10 mg Kg-1, while the highest levels measured were 30 g Kg-1. The leaf area index of deficient treatments is inferior to that of controls due to a lower number of leaves and smaller leaf sizes. In the greenhouse test, an important decrease of leaf area is observed but the proportion of the reduction due to a reduction in individual leaf size is more pronounced than in the filed experiments. The temporal analysis of the leaf area growth shows that the relative increase in size of the individual leaves is the same whatever the level of K-deficiency but that the size of the organs at emergence from apical buds is smaller for K-deficient plants. In counterpart, internodes of K-deficient plants have smaller lenght at emergence and a decreased relative growth rate. At stand level, no difference of light conversion efficiency is observed. As a result, observed reductions of dry biomass are essentially due to a decrease in light interception. However, radiation use efficiency in greenhouse tests are affected by K-deficiency but only for the most K-deficient treatment. Measures on gas exchanges made in greenhouse experiment also shows that photosynthesis is affected only for the most K-deficient treatments. This reduction is due to two concomitant effects: poor stomatal opening and a reduction in the maximum velocity of carboxylation. The relative distribution in biomass for all the tests is modified by the potassium-deficiency, benefiting leaves at the expense of the heterotrophic organs. This effect is observed at the plant level through an increase in the specific leaf weight and a relative decrease in stem and root biomass

Full textFor cotton (Gossypium hirsutum L.) to grow and develop normally, plants need to uptake the necessary amount of nutrients and use those nutrients in a beneficial fashion. It is recognized that cotton needs a certain tissue concentration of ions to achieve and maintain growth rates (Siddiqi et al., 1987). One of the most essential and abundant nutrients in cotton is potassium (K), second only by mass to nitrogen (N) (Marschner, 1995; Oosterhuis et al., 2013). Potassium exists in the soil in four separate pools and moves through soil to roots mainly through diffusion (Rengel & Damon, 2008; Samal et al., 2010; Ogaard et al., 2001). Potassium plays a vital role in plant growth and metabolism.
The objectives of this study were to determine the Michaelis-Menten parameters for the high-affinity transport system (HATS) and low-affinity transport system (LATS) uptake mechanisms of cotton, observe how K is partitioned throughout the cotton plant over a growing season with differing K fertilization rates, and to determine if cultivars differed in values from currently available indices formulated for N-status detection from active sensors. It also set out to determine if these N-sensitive indices were sensitive to leaf K concentration and available K2O in the soil, and to evaluate the role these indices play in predicting yield. It was hypothesized that a high K hydroponic environment would lead to more K uptake by cotton roots, which would lead to an increase in VMAX and KM. It was also hypothesized that with increased K fertilization, there would be greater K uptake and larger shift to reproductive components due to the plant having more than enough K in all other parts enabling it to send more to the reproductive components, and that greater K rates would lead to higher yields across all cultivars. It was believed that normalized difference vegetation index (NDVI) would more accurately predict leaf K, available K2O, and yield than normalized difference red edge (NDRE), that NDVI and NDRE would more accurately determine the K parameters chosen than canopy chlorophyll content index (CCCI), due to the strong influence of the red-edge band in the index and that yield would be most accurately predicted by the CCCI, due to yield being influenced by both chlorophyll content and biomass, and the CCCI involving the red-edge band to reflect chlorophyll content and the near infrared band to detect biomass.

Full textA major role of mutualistic interactions between plants and fungi is the improvement of plant nutrition by an exchange of nutrients, due to a better exploration of the soil and a better absorption of water and ions. Therefore, ectomycorrhizal symbiosis, established between woody plants and soil fungi, is crucial for the plant to efficiently take up poorly available nutrients in forest ecosystems. Physiological studies, recent genome sequencing projects and transcriptome analyses have allowed progress towards the identification and characterization of the fungal symbiotic transportome. Potassium (K+) is the most abundant cation in plant cells and is involved in various cellular and physiological processes. Improvement of K+ nutrition by ectomycorrhizal symbiosis has been shown under K+ shortage conditions using the model couple Pinus pinaster and Hebeloma cylindrosporum. Questions are raised to identify the fungal transport systems involved in the uptake of nutrients from the soil and in their transfer towards the plant at the symbiotic fungus-plant interface, called Hartig net. Two types of K+ transporters, Trk and HAK, have been identified as candidates to perform K+ uptake from the soil by extraradical hyphae, and two types of K+ channels, Shaker-like and TOK, that may release K+ by the hyphae of the Hartig net into the plant apoplasm. In my PhD, I focused my research on the three TOK (Two-pore Outward K+) channels of H. cylindrosporum, a channel family specific for fungi. These three TOK channels belong to two different subfamilies, which may imply different roles in potassium nutrition and in symbiosis. One member seems to be especially interesting because of its induction by mycorhization. My PhD aimed to complete the previous results on their functional characterization, expression, localization, and to contribute to the establishment of tools to analyze their physiological roles. In perspective, my results will contribute to a better understanding of the specific roles of these original TOK channel members within the fungus and within the symbiosis

Full textThis Ph.D. thesis focuses on the regulation of K+-Cl- cotransporter type 4 (KCC4) by WNK lysine deficient protein kinase 4 (WNK4), a serine threonine kinase that was discovered in 2001. The cotransporter KCC4 belongs to the cation-Cl- cotransporter (CCC) family that includes nine members. This transporter, along with the three other KCC isoforms, corresponds to cell surface proteins that couple elctroneutral efflux of Cl- with that of K+. In doing so, KCC family members regulate intracellular Cl- (Cl-i), cell volume (Vi) and basolateral reabsorption of Cl- across a variety of epithelia. Although they are activated by an increase in Cl-i and Vi, the signaling intermediates involved remain largely unknown to date. In this regard, WNK4 could correspond to one such intermediate given that it regulates several transport systems including KCC. On the basis of these premises, the main objectives of this thesis were to determine whether WNK4 regulates KCC4 activity during changes in Cl-i and Vi and if so, through which mechanisms. To address these objectives, I exploited a structure-function approach in which mutations were introduced in both KCC4 or WNK4 and in which the effect of such mutations were analyzed in the Xenopus laevis expression system through functional, expression, immunofluorescence studies and phosphorylation. My studies allowed to show for the first time that WNK4 et PP1 are indeed involved in KCC4 regulation during an increase in Vi, but that in contrast to previous assumptions, PP1 would act downstream instead of upstream of WNK4, and that it would also act on KCC4 through additional signaling intermediates. Lastly, we have identified two residues in the C-terminus of KCC4 that mediate the effect of WNK4 and PP1. Taken together, these results could help identifying new signaling pathways of KCC4 regulation by WNK4 and PP1, and thus offer other therapeutic targets to treat electrolyte disorders.
