Human colorectal peptides
were subjected to basic-pH reverse-phase
HPLC fractionation. Mixed and labeled peptides were solubilized in
buffer A (5% ACN, 10 mM ammonium bicarbonate, pH 8.0) and separated
on an Agilent 300 Extend C18 column (5 μm particles, 4.6 mm
i.d., and 20 cm in length). Using an Agilent 1100 binary pump equipped
with a degasser and a photodiode array (PDA) detector, a 50 min linear
gradient from 18% to 45% acetonitrile in 10 mM ammonium bicarbonate
pH 8 (flow rate of 0.8 mL/min) separated the peptide mixture into
a total of 96 fractions. The 96 fractions were consolidated into 24
samples, acidified with 10% formic acid, and vacuum-dried. Each sample
was redissolved with 5% formic acid/5% ACN, desalted via StageTip,
dried via vacuum centrifugation, and reconstituted for LC–MS/MS
analysis.
All LC–MS experiments were performed on a Velos-Orbitrap
Elite mass spectrometer (Thermo Fischer Scientific) coupled to a Proxeon
nLC-1000 (Thermo Fisher Scientific) ultra high-pressure liquid chromatography
(UPLC) pump. Peptides were separated on a 75 μm inner diameter
microcapillary column. The tip for the column was pulled in-house
and the column was packed with approximately 0.5 cm of Magic C4 resin
(5 μm, 100 Å, Michrom Bioresources) followed by 25 cm of
Sepax Technologies GP-C18 resin (1.8 μm, 120 Å). Separation
was achieved by applying a 3–22% ACN gradient in 0.125% formic
acid over 165 min at ∼300 nL/min. Electrospray ionization was
enabled by applying a voltage of 2.0 kV through an IDEX high-pressure
fitting at the inlet of the microcapillary column. In the case of
the two-proteome mixture, the linear gradient was shortened to 70
min.

Human breast epithelial cells (MCF10A) were transfected with a pQCXIH vector and were cultured in DMEM/F12 (Invitrogen, Carlsbad, CA) supplemented with 5% horse serum (Invitrogen), 20 ng/mL EGF, 0.5 μg/mL hydro-cortisone, 100 ng/mL cholera toxin, 10 μg/mL insulin, and 50 μg/mL penicillin/streptomycin until 70–80% confluence was reached. The cells were then lysed in a buffer containing 8 M urea, 2.5 mM sodium pyrophosphate, 1 mM β-glycerophosphate, 50 mM ammonium bicarbonate, one-third tablet of protease inhibitor, and 2 mM sodium ortho-vanadate. Proteins were denatured, reduced, and alkylated after which tryptic digestions were performed at an enzyme/substrate ratio of 1:50. For method comparison between SCX and RP, digested peptides were cleaned by flowing through a 1 mL solid-phase extraction C18 column (Discovery DSC-18, SUPELCO, Bellefonte, PA). Samples were concentrated using a Speed-Vac SC 250 Express (Thermo Savant, Holbrook, NY) and stored at −80°C until time for analysis. A 300.0 μg desalted peptide sample was used for each SCX, low-pH RPLC, and high-pH RPLC fractionation. A 300.0 μg nondesalted protein digest was used to evaluate the potential of high-pH approach for desalting.

Leiker bAL222 was used to cross-link the E. coli MG1655 whole-cell lysates. MG1655 was cultured in unlabeled or 15N-labeled M9 medium and collected at OD600 0.6–0.8. Pellets of 40 OD*ml E. coli cells was resuspended in 0.4 ml lysis buffer (50 mM HEPES, pH 7.5, 150 mM NaCl). Cell lysates were prepared using a FastPrep homogenizer (6.5 m/s, 20 s, repeat 5 times). After measuring protein concentration, 1 mg of unlabeled and 15N-labeled lysate was cross-linked separately with 0.33 mg [d0]-bAL2 for 0.5 h at room temperature. Cross-linking reactions were quenched with 20 mM ammonium bicarbonate. The two reactions were mixed together and then precipitated by trichloroacetic acid (TCA) followed by Trypsin digestion. After filtering with a 50 kDa cutoff Amicon Ultra-0.5 Centrifugal Filter Unit, the digested peptides were brought to a volume of 3 mL with 2% ACN, 20 mM HEPES, pH 8.2; the pH was adjusted to 10.0 with ammonia. High-pH reverse-phase separation was used for fractionation. The peptides were eluted with buffer B (80% ACN, 5 mM NH4COOH, pH 10) gradient. A total of 39 two-minute fractions were collected and then combined into five fractions of similar shades of color (bAL2-linked peptides are bright yellow before cleavage of the biotin tag). Each pooled sample was evaporated to 200–300 µl before enrichment of bAL2-linked peptides on 50 µl high-capacity streptavidin beads. After release of beads and desalting through a C18 column, the five fractions of bAL2-linked peptides were analyzed by liquid chromatography–tandem mass spectrometry (LC-MS/MS) using a Q-Exactive HF mass spectrometer coupled with an EASY-nLC 1000 system (both from Thermo Fisher Scientific). Precursors of the + 1, + 2, + 8, or above, or unassigned charge states were rejected and dynamic exclusion was set to 20 s.

The E. coli K12 strain was grown in standard LB medium, harvested, washed in PBS, and lysed in 4% SDS, 100 mm Tris, pH 8.5. Lysates were briefly boiled and DNA sheared using a Sonifier (Branson Model 250). Lysates were cleared by centrifugation at 15,000 × g for 15 min and precipitated with acetone. Proteins were resuspended in 8 m urea, 25 mm Tris, pH 8.5, 10 mm DTT. After 30 min of incubation, 20 mm iodoacetamide was added for alkylation. The sample was then diluted 1:3 with 50 mm ammonium bicarbonate buffer, and the protein concentration was estimated via tryptophan fluorescence emission assay. After 5 h of digestion with LysC (Wako Chemicals) at room temperature, the sample was further diluted 1:3 with ammonium bicarbonate buffer, and trypsin (Promega) digestion was performed overnight (protein-to-enzyme ratio of 60:1 in each case). E. coli peptides were then purified by using a C18 Sep Pak cartridge (Waters, Milford, MA) according to the manufacturer's instructions. UPS1 and UPS2 standards (Sigma-Aldrich) were resuspended in 30 μl of 8 m urea, 25 mm Tris, pH 8.5, 10 mm DTT and reduced, alkylated, and digested in an analogous manner, but with a lower protein-to-enzyme ratio (12:1 for UPS1 and 10:1 for UPS2, both LysC and trypsin). UPS peptides were then purified using C18 StageTips. E. coli and UPS peptides were quantified based on absorbance at 280 nm using a NanoDrop spectrophotometer (Fisher Scientific). For each run, 2 μg of E. coli peptides were then spiked with 0.15 μg of either UPS1 or UPS2 peptides, and about 1.6 μg of the mix was then analyzed via liquid chromatography combined with mass spectrometry on a Q Exactive (Thermo Fisher). Data were analyzed with MaxQuant as described above for the proteome dataset. All files were searched against the E. coli complete proteome sequences plus those of the UPS proteins and common contaminants.

The greenhouse experiment was performed from March to May 2021 under controlled conditions: 30/18°C day/night temperature and 10/14 h light/dark photoperiod (Zhang et al., 2022b (link)). The pots (24 × 18 cm diameter) were filled with 3.5 kg/pot of diseased soil heavily infected with clubroot pathogen collected from the field (Xiadabai County, Kunming, China). Lime and ammonium bicarbonate were added to each pot at the ratio 1:1,300 (m/m), mixed thoroughly with the diseased soil, covered with plastic film (0.08 mm), and placed in a greenhouse at >35°C. The experiment was performed under four different conditions: NB; soil fumigation with lime (2.69 g/pot), N; soil fumigation with ammonium bicarbonate (2.69 g/pot), LNB; soil fumigation with combined ammonium bicarbonate (2.69 g/pot) and lime (2.69 g/pot), and GZ; no soil fumigation as control. After 15 days of anaerobic soil fumigation, Chinese cabbage seedlings were transplanted in pots (5 plants/pots). In addition, fertilizer was applied in each pot before the transplantation of seedlings to overcome the nutrient deficiency (Wei et al., 2021 (link)). The experiment was repeated three times with 15 plants per replication (in total, 45 plants/treatment) and was accomplished using a completely randomized design.

Seeds of wheat (cultivar Jimai 22) were surface-sterilized using 70% ethanol for 45 s and washed 5 times with distilled water. The sterilized seeds were then germinated on moist filter paper placed inside Petri dishes at 23 °C. After 3 days, the uniform-sized seedlings were transferred to black plastic pots with dimensions of 10 cm × 8 cm × 5 cm (length, width, height) containing distilled water and grown in a growth chamber at 25 °C/21 °C (day/night) under 14 h/10 h (light/dark) for 5 days under the following conditions: light intensity 450 µmol m−2 s−1 and humidity 70 ± 5%. Each pot contained 15 plants and the distilled water was renewed every 2 days.
In our preliminary experiment, we found that the roots of 8-day-old seedlings grew best in half-strength Hoagland nutrient solution containing 7.5 mM NO3 (Table S1), and 7.5 mM NH4+ showed significant inhibition of root growth compared with 7.5 mM NO3. An experiment using gradient concentrations showed that 3 mM HCO3 significantly improved the root growth of wheat seedlings fed 7.5 mM NH4+. Therefore, the following experiment was conducted using 8-day-old seedlings that were fixed on polystyrene plates and hydroponically cultured in half-strength Hoagland nutrient solution containing 7.5 mM NO3 (CK, applied as KNO3 and Ca(NO3)2), 7.5 mM NH4+ (sole ammonium (SA), applied as 7.5 mM NH4Cl), or 7.5 mM NH4+ + 3 mM HCO3 (ammonium and bicarbonate (AC), applied as 7.5 mM NH4Cl and 3 mM KHCO3). The solutions were renewed every 2 days. Each treatment was repeated in triplicate. Potassium in the nutrient solution was balanced by the addition of K2SO4.

A soil sample bag with a height of 30 cm and an inner diameter of 10 cm was adopted. The soil required to fill a 21 cm soil column was calculated as 850 g, and the air-dried soil treated in the early stage was weighed and evenly filled to form a soil column. The soil was treated with water injection to ensure that the water content in the bag was 30%, 40%, and flooded, respectively, and stood for 24 h. Each soil water content was treated as follows: local farmers commonly use urea, ammonium bicarbonate, ammonium bicarbonate, and ammonium sulfate. Four nitrogen fertilizers (i.e., ammonium bicarbonate, ammonium sulfate, ammonium chloride, and urea) were treated with oxalic acid, DMPP, and NBPT, respectively (A1 ammonium bicarbonate, A2 ammonium bicarbonate + oxalic acid, A3 ammonium bicarbonate +DMPP, A4 ammonium bicarbonate +NBPT, collectively referred to as A treatment; B1 ammonium sulfate, B2 ammonium sulfate + oxalic acid, B3 ammonium sulfate +DMPP, B4 ammonium sulfate +NBPT, collectively referred to as B treatment; C1 ammonium chloride, C2 ammonium chloride + oxalic acid, C3 ammonium chloride +DMPP, C4 ammonium chloride +NBPT, collectively referred to as C treatment; D1 urea, D2 urea + oxalic acid, D3 urea +DMPP, D4 urea +NBPT, collectively referred to as D treatment). Each treatment was replicated three times. The mixture was applied to the surface of the soil column after resting. Then, the soil was covered at 135 g, the height was 3 cm, and the specific amount of water injected was calculated according to the quality of the covering soil. The mouth of the soil column was wrapped and sealed with a rope, and five small holes with a diameter of about 1 cm were pricked with needles to ensure ventilation, avoid an anaerobic environment, reduce water loss, and maintain soil water content during cultivation. Then, the soil column was placed horizontally indoors for 30 days.

Determination of the cAMP content of purified CNBD proteins performed following the procedure previously described13 (link). Endogenous cAMP bound to His6-MBP tagged HCN1/2 CNBDs purified from Escherichiacoli Rosetta strain (EMD Millipore) was released by boiling the protein sample (∼1 mg) for 2 min. The boiled protein samples were centrifuged at maximum speed for 10 min, at room temperature, and the supernatant was diluted in 5 mM ammonium bicarbonate. The sample was loaded onto an anion exchange chromatography column (HiTrapQ (1 ml), GE Healthcare), previously equilibrated with 5 mM ammonium bicarbonate. After a washing step (7 column volumes) with 5 mM ammonium bicarbonate, cAMP was eluted with a linear gradient of ammonium bicarbonate (5–1000 mM) in 20 column volumes. Calibration curves were performed by loading in the HiTrapQ column 5, 10 and 20 nmoles of cAMP diluted in 5 mM ammonium bicarbonate. Chromatographies were performed at 4 °C and monitored using the AKTApurifier UPC 10 fast protein liquid system (GE Healthcare). Calculation of the area of the peaks of cAMP eluted from the HiTrapQ column was performed by using the software UNICORN5.11.
